atmIfConnMapVccProvTableThis group is obsolete. Please refer to the Override component
below for the current provisioning group
This group contains provisionable attributes which specify the VCC
space to be supported by an ATM interface. The VCC space
consists of an optional 'VPI Zero VCC Space' and an optional
'Programmable VCC Space'.
The VPI Zero VCC Space is used to support VCCs with a VPI of
zero. The VCI values supported in this space range from 0 to a
provisioned maximum. The size of the VPI Zero VCC Space must
either be 0 or a multiple of 256. A value of 0 implies that no
programmable VCCs can be used. In this case
atmNumberOfNonZeroVpisForVccs_m must also be 0.
The optional Programmable VCC Space is used to support VCCs
with a VPI other than zero. The VPI values supported in this space
must lie in a single contiguous range which excludes VPI 0. The
VCI values supported in this space range from 0 to a provisioned
maximum. The size of the Programmable VCC Space (should it
exist) must adhere to the following rules:
If (firstNonZeroVpiForVccs = 1) THEN
(numNonZeroVpisForVccs + 1) *
numVccsPerNonZeroVpi must be a multiple of 256
OTHERWISE
numNonZeroVpisForVccs * numVccsPerNonZeroVpi

If the AtmIf is linked to a LogicalProcessor with a cardType of
3pE3Atm, 3pDS3Atm, 3pOC3MmAtm, 3pOC3SmAtm, 3pE1Atm,
3pDS1Atm or 2pJ6MAtm, the size of the entire VCC space (both
mandatory and optional parts) and VPC space must not exceed the
capacity of the port to which the interface is linked, which is
defined in the Arc component's totalConnectionPoolCapacity or
connectionPoolCapacity attribute (whichever is non-zero). When
using the totalConnectionPoolCapacity attribute, the capacity of the
port is (totalConnectionPoolCapacity divided by the number of
physical ports). The number of connection identifiers in the VCC
and VPC space can be determined as follows:
IF (numNonZeroVpisForVccs = 0) THEN
number of connection ids = 256 + numVccsForVpiZero

atmIfConnMapOperTableThis group contains operational attributes which specify the VCC
space to be supported by an ATM interface. The VCC space
consists of an optional 'VPI Zero VCC Space' and an optional
'Programmable VCC Space'.
The VPI Zero VCC Space is used to support VCCs with a VPI of
zero. The VCI values supported in this space range from 0 to an
optionally provisioned maximum of numVccsForVpiZero. The size
of the VPI Zero VCC Space is either 0 or a multiple of 256. A value
of 0 implies that not only can no VCCs be provisioned in the VPI
Zero VCC Space but no Programmable VCCs can be used. In this
case numNonZeroVpisForVccs will also be 0.
The optional Programmable VCC Space supports VCCs with a VPI
other than zero. The VPI values supported in this space lie in a
single contiguous range which excludes VPI 0. The VCI values
supported in this space range from 0 to an optionally provisioned

conforming or non-conforming based on the connection's traffic
descriptor type. The larger the CDVT value, the more tolerant is the
UPC of bandwidth usage beyond the traffic contract.rw Unsigned32 .1.3.6.1.4.1.3764.1.1.30.114.3.2.100.1.20 |
atmIfCACbrCdvThis attribute specifies the peak-to-peak cell delay variation (CDV)
which is contributed to the entire ATM Interface for CBR traffic.
The CDV is a measure of the delay jitter introduced mostly by
traffic buffering and cell scheduling. The worst case value of this
attribute can be computed as the txQueueLimit divided by the link
rate of this ATM Interface.
The value of this attribute is used by PNNI in the Resource
Availability Information Group (RAIG) topology updates and route
selection. It is also used by CAC at connection set-up time to
determine whether this ATM Interface can meet the CDV
requirements of the connection. If so, the value of this attribute is
added to the cumulative CDV field of the extended QoS information
element.rw Unsigned32 .1.3.6.1.4.1.3764.1.1.30.114.3.2.100.1.30 |
atmIfCACbrMaxCtdThis attribute specifies the maximum cell transfer delay (MaxCTD)
which is applied to the entire ATM Interface for CBR traffic.
MaxCTD is the sum of the fixed delay and the CDV. The
components of the fixed delay include propagation delay through
the physical media, delays induced by the transmission system, and
fixed components of switch processing delay.
This attribute is used by PNNI in the Resource Availability
Information Group (RAIG) topology updates and route selection. It
is also used by CAC at connection set-up time to determine whether
this ATM Interface can meet the ATM connection's MaxCTD
requirement.rw Unsigned32 .1.3.6.1.4.1.3764.1.1.30.114.3.2.100.1.40 |
atmIfCACbrProvClrThis attribute specifies the tolerable cell loss ratio (CLR) for CBR
traffic except for connections managed by a Vpt CA. The number is
the negative logarithm (base 10) of the CLR. For example, if the
target CLR = 1E-10 then Cbr cellLossRatio = 10. This number must
be the same as the RtVbr cellLossRatio since CBR and rt-VBR
traffic have the same discard priority. The Cbr cellLossRatio is used
by the Connection Admission Control (CAC) algorithm to compute
the required (equivalent) cell rate for CBR connections.
There is a trade-off between the service category CLR and the
achievable link utilization. To guarantee an excellent service
category, the CLR should be as small as possible (e.g., 1E-10).
However, a smaller CLR results in a larger equivalent cell rate for a
given connection and hence a lower link utilization.
Setting this attribute to 0 means that a CLR of 1 can be tolerated. In
this case, no bandwidth is reserved for CBR connections, and CAC
is effectively turned off. All CBR connections are admitted.rw Unsigned32 .1.3.6.1.4.1.3764.1.1.30.114.3.2.100.1.50 |
atmIfCACbrTxQueueLimitThis attribute specifies the default maximum queue length for the
emission queues used to buffer the traffic of the CBR service
category. It is used as the basis for setting the discard thresholds on
both common and per-VC queues. For the common queue, the
discard thresholds are set at approximately 35, 75, and 90 percent of
the value of this attribute for traffic at discard priority 3 (DP=3),
DP=2 and DP=1 respectively.
For a per-VC queue, the actual limit may be reduced depending on
the shaping rate of the connection (for standard Vpt Vccs, this is the
shaping rate of the Vpt). The discard thresholds are set at
approximately 35, 75 and 90 percent of the scaled queue limit for
traffic at discard priority 3 (DP=3), DP=2 and DP=1 respectively.
However, a reduction will never result in a value that is less than the
value set for the minPerVcQueueLimit attribute. CQC-based ATM
cards do not support per-VC queues at the CBR service category.
When this attribute is set to autoConfigure, an appropriate value is
selected based on the card type. It is set to 96 for all Passport ATM
cards (DS1, E1, IMA, JT2, DS3, E3, OC3, both CQC-based cards
and ATM IP cards).
For ATM IP FPs, the per-VC queue limit may be overridden for a
permanent connection by specifying a value in the Vcd Tm or Vpd
Tm txQueueLimit attribute.
The operational value of the maximum length of a queue (common
or per-VC) is indicated by the Vcc Tm, Vpc Tm, or Vpt Tm
txQueueThresholds attribute.
For standard Vpts, this attribute does not apply when using per-VC
queuing and only applies when using common queueing. When
using per-VC queueing, regardless of the Vpt's service category,
standard Vpts use the AtmIf Ca NrtVbr txQueueLimit value as their
default.
This attribute does not apply to basic Vpts.

atmIfCACbrHoldingPriorityThis attribute specifies the holding priority which applies to SVP
and SVC CBR connections. It takes a value from 0 (highest
priority) to 4 (lowest priority). In a situation where the link
bandwidth fluctuates, such as over an IMA link, holding priority is
used to determine which connections are held and which are
released. Holding priority 4 connections are the first to be released.
Holding priority 0 connections are the last to be released.

atmIfCACbrMinPerVcQueueLimitThis attribute specifies the minimum queue limit for the per-VC
queues of connections of the CBR service category.
This attribute is ignored on CQC-based ATM cards, because they do
not support per-VC queues at the CBR service category.
The queue limit of a per-VC queue is obtained by scaling down the
txQueueLimit based on the shaping rate of that queue (shaping rate
for the connection, and for standard Vpt Vccs, the shaping rate of
the Vpt). This produces a constant delay for various queue lengths.
The txQueueLimit provides an upper bound while
minPerVcQueueLimit provides the lower bound. The value of this
attribute must not be greater than the value of the txQueueLimit
attribute. If this service category is used by Trunks the value of
minPerVcQueueLimit must be at least 88.
For Vpts, this attribute does not apply. Regardless of Vpt service
category, standard Vpts always use the AtmIf Ca NrtVbr
minPerVcQueueLimit value as their default. To determine the queue
limit of a standard Vpt Vcc, the txQueueLimit is scaled down by the
Vpt shaping rate.rw Unsigned32 .1.3.6.1.4.1.3764.1.1.30.114.3.2.100.1.80 |
atmIfCACbrPerVcQueueLimitReferenceRateThis attribute specifies the shaping rate to be used in computing the
tolerable delay for per-VC queues of connections of the CBR
service category. The delay is computed as the txQueueLimit
divided by the value of this attribute.
This attribute is ignored on CQC-based ATM cards, because they do
not support per-VC queues at the CBR service category.
When the value of this attribute is autoConfigure, an appropriate
default is selected based on the card type. It is set to 80000 for all
cards which support per-VC queuing at the CBR service category
(3pDS3Atm2, 3pE3Atm2, 2pOC3SmAtm2, 2pOC3MmAtm2).
For Vpts, this attribute does not apply. Regardless of Vpt service

atmIfCACbrEmissionPriorityThis attribute is not applicable and is ignored for CQC-based ATM
cards.
This attribute specifies the emission priority (EP) which is used to
transmit traffic of the CBR service category. A lower numerical
value for this attribute specifies a higher emission priority. 0 is the
highest EP and 7 is the lowest. Cells at a higher emission priority
receive higher preference for link bandwidth. EPs 0 and 1 are in the
absolute priority range, and are unaffected by any minimum
bandwidth guarantees. EPs 2 through 7 are in the guaranteed
bandwidth range. Minimum bandwidth guarantee is specified in the
AtmIf/n Ep/m component.
Emission priority setting must comply with all of the following
constraints:
1. The emission priority numbers must be in the following order:
CBR <= rt-VBR <= nrt-VBR <= ABR <= UBR
2. Two different ATM service categories may share the same EP
only if they are both shaped.
3. CBR and rt-VBR may be placed either in the absolute priority
range (EP 0 or 1) or in the guaranteed bandwidth range (EP 2
through 7).
4. If both CBR and rt-VBR are shaped, rt-VBR must share the
same EP with CBR or ABR. If either one of CBR or rt-VBR are
not shaped, then they cannot share the same EP.
5. ABR service category is always deemed to be shaped. If nrt-VBR
is shaped, it must share the same EP with ABR. If nrt-VBR is not
shaped it must have a higher EP than ABR.
6. If UBR is shaped, it must share the same EP with ABR. If UBR
is not shaped, it must have a lower EP than ABR.

atmIfCACbrTrafficShapingThis attribute specifies the default traffic shaping option for
connections of the CBR service category. An override to this default
may be specified for a provisioned connection under the Vcd Tm or
Vpd Tm component.
When this attribute is set to disabled, traffic shaping cannot be
enabled for any CBR connections.
For CQC-based ATM FPs, this attribute must be set to disabled.
Traffic shaping is not supported for CBR connections on CQC-
based ATM FPs.
If the Vcc Tm, Vpc Tm, or Vpt Tm txTrafficDescType indicates type
1 or 2, this attribute is ignored, and traffic shaping is not applicable
for that connection.
When this attribute is set to inverseUpc, traffic shaping for a
connection is enabled according to the value of the Vcc Tm, Vpc
Tm, or Vpt Tm txTrafficDescType.
If this attribute is set to inverseUpc, and the txTrafficDescType is 3,
4, or 5, linear traffic shaping is enabled. Linear traffic shaping uses
a single static traffic shaping rate.
If this attribute is set to inverseUpc, and the txTrafficDescType is 6,
7, or 8, inverse-UPC (also referred to as VBR or dual leaky bucket)
traffic shaping is enabled. Inverse-UPC traffic shaping can burst
above the sustained cell rate to the peak cell rate for the duration
defined by maximum burst size. Inverse-UPC traffic shaping exactly
conforms to the requirements of a dual leaky bucket UPC enforcer.
When this attribute is set to enabled and the txTrafficDescType is 3,
4, 5, 6, 7, or 8, traffic shaping for a connection is enabled using
linear shaping.
Enabling or disabling traffic shaping may require a matching
change to the emissionPriority attribute and
unshapedTransmitQueueing attribute for this service category.

atmIfCACbrShapeRecoupPolicyThis attribute specifies the shaping recoup policy for the CBR
service category. This is the policy which is used to recoup shaping
opportunities which are lost when more than one connection
schedules a cell for the same transmit opportunity. In this case, one
connection is scheduled, and the cell from the other connection is
delayed by one cell time. This attribute affects how the transmit
time is calculated for the next cell on the delayed connection. This
attribute is ignored if this service category is not shaped.
When the connection which was delayed schedules the next cell to
transmit, it may calculate the time as a difference from either the
previous actual cell transmit time, or the time when the previous
cell should have been transmitted.
Setting this attribute to maximumEfficiency results in each
connection trying to recoup or regain any delays in scheduling. The
transmit time from the next cell is calculated from the time when
the cell should originally have been sent. Cell delay variation
(CDV) occurs in this case since the cells are sent with less than the
shaping delay between them. However, in general the shaper
recovers (recoups) lost opportunities and improves efficiency.
Setting this attribute to minimumCdv results in connections not
trying to recoup or regain any delays in scheduling. The transmit
time for the next cell is calculated from the time when the previous
cell was actually transmitted. This minimizes CDV, but results in
missed cell opportunities.

atmIfCACbrUnshapedTransmitQueueingThis attribute specifies the default queuing option for unshaped
connections of the CBR service category. On ATM IP cards, this
attribute controls whether common or per-VC queueing is used.
Per-VC queueing means that each connection has its own buffering
and queue limits.
Common queueing means that cells are queued in First In First Out
order on a common queue for this service category. The common
queue has one set of congestion control levels for all cells enqueued
on it.
For CQC-based ATM cards, this attribute must be set to common.
CQC-based ATM cards do not support per-VC queueing for the
CBR service category.
For ATM IP cards, if traffic shaping for this service category is not
disabled, this attribute must be set to perVc.

atmIfCACbrWeightPolicyThis attribute specifies the default policy which is applied when
calculating the fairness weight for unshaped connections of the
CBR service category. The fairness weight for a connection
determines the relative amount of bandwidth which that connection
obtains, compared to other connections in the same service
category. Connections with equal weight get equal transmit
opportunities. Connections with higher weights get more transmit
opportunities compared with connections that have lower weights.
An override to this default may be specified for a provisioned
connection under the Vcd Tm or Vpd Tm component.
The fairness weight for a connection is directly proportional to the
value of one of the traffic descriptor parameters for that connection.
This attribute specifies which traffic descriptor parameter is used for
connections of the CBR service category.
This attribute is ignored on CQC-based ATM cards. This attribute is
also ignored on ATM IP cards if unshapedTransmitQueueing is set
for common queuing.
If this attribute is set to scr, the fairness weight is proportional to the
transmit sustained cell rate (SCR) of a connection. Connections
with a higher SCR have a higher fairness weight. For connections
with txTrafficDescType 3, which have no SCR, the sustained cell
rate is assumed to be equal to the peak cell rate.
If this attribute is set to pcr, the fairness weight is proportional to
the transmit peak cell rate (PCR) of a connection. Connections with
a higher PCR have a higher fairness weight. Connections with
txTrafficDescType 1 or 2 get a minimum weight, which is 1.
If this attribute is set to ecr, the fairness weight is proportional to
the equivalent cell rate (ECR) of a connection as calculated by
connection admission control (CAC). Connections with a higher
ECR have a higher fairness weight. Connections with an ECR of 0
get a minimum weight, which is 1.
The weight of a connection is visible in the Vcc Tm, Vpc Tm, or Vpt
Tm weight attribute.

atmIfCACbrForceTaggingThis attribute specifies the default of whether to force tagging
(CLP=1) of all cells for all CBR connections. An override to this
default may be specified for a provisioned connection under the Vcd
Tm or Vpd Tm component.
When this attribute is set to enabled, CLP is set to 1 for all cells in
the transmit direction. Force tagging is only supported on ATM IP
FPs.
On CQC-based ATM FPs, this attribute must be set to disabled.
When this attribute is set to disabled, CLP is unchanged for all cells
in the transmit direction.

atmIfCACbrUsageParameterControlThis attribute specifies the default usage parameter control (UPC)
option for connections of the CBR service category. This attribute is
ignored if the rxTrafficDescriptorType indicates 1 or 2. An override
to this default may be specified for a provisioned connection under
the Vcd Tm or Vpd Tm component.
When this attribute is set to enforced, UPC is enforced by default
for each connection. When UPC is enforced, non-conforming cells
are either tagged or discarded depending on the
rxTrafficDescriptorType.
On ATM IP FPs, when this attribute is set to monitored, UPC
conformance checking is performed, except, instead of the non-
conforming cells being tagged or discarded, they are merely
counted in the UPC violations counts, and passed on unchanged.
On CQC-based ATM FPs, when this attribute is set to monitored, it
has the same effect as setting it to disabled.
When this attribute is set to disabled, UPC is disabled on the receive
path for all CBR connections.

If Usage Parameter Control (UPC) is enabled for a connection,

atmIfCARtVbrCdvThis attribute specifies the peak-to-peak cell delay variation (CDV)
which is contributed to the entire ATM Interface for rt-VBR traffic.
The CDV is a measure of the delay jitter introduced mostly by
traffic buffering and cell scheduling. The worst case value of this
attribute can be computed as the txQueueLimit divided by the link
rate of this ATM Interface.
The value of this attribute is used by PNNI in the Resource

determine whether this ATM Interface can meet the CDV
requirement for that connection. If so, the value of this attribute is

atmIfCARtVbrMaxCtdThis attribute specifies the maximum cell transfer delay (MaxCTD)
which is applied to the entire ATM Interface for rt-VBR traffic.
MaxCTD is the sum of the fixed delay and the CDV. The
components of the fixed delay include propagation delay through
the physical media, delays induced by the transmission system, and
fixed components of switch processing delay.

atmIfCARtVbrCellLossRatioThis attribute specifies the tolerable cell loss ratio (CLR) for rt-
VBR traffic except for connections managed by a Vpt CA. The
number is the negative logarithm (base 10) of the CLR. For
example, if the target CLR = 1E-10 then RtVbr cellLossRatio = 10.
This number must be the same as the Cbr cellLossRatio since CBR
and rt-VBR traffic have the same discard priority. The RtVbr
cellLossRatio is used by the Connection Admission Control (CAC)
algorithm to compute the required (equivalent) cell rate for rt-VBR
connections. This number must be less than or equal to the NrtVbr
cellLossRatio, since rt-VBR traffic has a higher discard priority.
There is a trade-off between the service category CLR and the
achievable link utilization. To guarantee an excellent service
category, the CLR should be as small as possible (e.g., 1E-10).
However, a smaller CLR results in a larger equivalent cell rate for a
given connection and hence a lower link utilization.
Setting this attribute to 0 means that a CLR of 1 can be tolerated. In
this case, no bandwidth is reserved for rt-VBR connections, and
CAC is effectively turned off. All rt-VBR are admitted.rw Unsigned32 .1.3.6.1.4.1.3764.1.1.30.114.3.3.100.1.50 |
atmIfCARtVbrTxQueueLimitThis attribute specifies the default maximum queue length for the
emission queues used to buffer the traffic of the rt-VBR service
category. It is used as the basis for setting the discard thresholds on
both common and per-VC queues. For the common queue, the
discard thresholds are set at approximately 35, 75, and 90 percent of
the value of this attribute for traffic at discard priority 3 (DP=3),
DP=2, and DP=1 respectively.
For a per-VC queue, the actual limit may be reduced depending on
the shaping rate of the connection (for standard Vpt Vccs, this is the
shaping rate of the Vpt). The discard thresholds are set at
approximately 35, 75, and 90 percent of the scaled queue limit for
traffic at discard priority 3 (DP=3), DP=2, and DP=1, respectively.
However, a reduction will never result in a value that is less than the
value set for the minPerVcQueueLimit attribute.
When the value of this attribute is autoConfigure, an appropriate
value is selected based on the card type. It is set to 288 for low
speed cards such as DS1, E1 and IMA, and set to 480 for high
speed cards such as JT2, DS3, E3 and OC3 (including ATM IP
FPs).
For ATM IP FPs, the per-VC queue limit may be overridden for a
permanent connection by specifying a value in the Vcd Tm or Vpd
Tm txQueueLimit attribute.
The operational value of the maximum length of a queue (common
or per-VC) is indicated by the Vcc Tm, Vpc Tm, or Vpt Tm
txQueueThresholds attribute.
For standard Vpts, this attribute does not apply when using per-VC
queuing and only applies when using common queueing. When
using per-VC queueing, regardless of the Vpt's service category,
standard Vpts use the AtmIf Ca NrtVbr txQueueLimit value as their
default.

atmIfCARtVbrMinPerVcQueueLimitThis attribute specifies the minimum queue limit for the per-VC
queues of connections of the rt-VBR service category.
The queue limit of a per-VC queue is obtained by scaling down the
txQueueLimit based on the shaping rate of that queue (shaping rate

the Vpt). This produces a constant delay for various queue lengths.
The txQueueLimit provides an upper bound while
minPerVcQueueLimit provides the lower bound. The value of this
attribute must not be greater than the value of the txQueueLimit

minPerVcQueueLimit must be at least 88.
For Vpts, this attribute does not apply. Regardless of Vpt service
category, standard Vpts always use the AtmIf Ca NrtVbr
minPerVcQueueLimit value as their default. To determine the queue
limit of a standard Vpt Vcc, the txQueueLimit is scaled down by the

When the value of this attribute is autoConfigure, an appropriate
default is selected based on the card type. It is set to 3685 for low
speed cards such as DS1, E1, and IMA, and set to 14740 for high

atmIfCARtVbrEmissionPriorityThis attribute is not applicable and is ignored for CQC-based ATM
cards.
This attribute specifies the emission priority (EP) which is used to
transmit traffic of the rt-VBR service category. A lower numerical
value for this attribute specifies a higher emission priority. 0 is the
highest EP and 7 is the lowest. Cells at a higher emission priority
receive higher preference for link bandwidth. EPs 0 and 1 are in the
absolute priority range, and are unaffected by any minimum
bandwidth guarantees. EPs 2 through 7 are in the guaranteed
bandwidth range. Minimum bandwidth guarantee is specified in the
AtmIf/n Ep/m component.
Emission priority setting must comply with all of the following
constraints:
1. The emission priority numbers must be in the following order:
CBR <= rt-VBR <= nrt-VBR <= ABR <= UBR
2. Two different ATM service categories may share the same EP
only if they are both shaped.
3. CBR and rt-VBR may be placed either in the absolute priority
range (EP 0 or 1) or in the guaranteed bandwidth range (EP 2
through 7).
4. If both CBR and rt-VBR are shaped, rt-VBR must share the
same EP with CBR or ABR. If either one of CBR or rt-VBR are
not shaped, then they cannot share the same EP.
5. ABR service category is always deemed to be shaped. If nrt-VBR
is shaped, it must share the same EP with ABR. If nrt-VBR is not
shaped it must have a higher EP than ABR.
6. If UBR is shaped, it must share the same EP with ABR. If UBR
is not shaped, it must have a lower EP than ABR.

atmIfCARtVbrTrafficShapingThis attribute specifies the default traffic shaping option for
connections of the rt-VBR service category. An override to this
default may be specified for a provisioned connection under the Vcd
Tm or Vpd Tm component.
When this attribute is set to disabled, traffic shaping cannot be
enabled for any rt-VBR connections.
For CQC-based ATM cards, this attribute may be set to enabled
only if the interface supports shaping, as defined by the
perVcQueueInterfaces attribute in the AtmResourceControl Cqc
Override component. If that component does not exist, this attribute
must be set to disabled.
If the Vcc Tm, Vpc Tm, or Vpt Tm txTrafficDescType indicates type
1 or 2, this attribute is ignored, and traffic shaping is not applicable
for that connection.
When this attribute is set to inverseUpc, traffic shaping for a
connection is enabled according to card type and the value of the
Vcc Tm, Vpc Tm, or Vpt Tm txTrafficDescType.
If this attribute is set to inverseUpc, and the txTrafficDescType is 3,
4, or 5, linear traffic shaping is enabled. Linear traffic shaping uses
a single static traffic shaping rate.
On CQC-based ATM FPs, if this attribute is set to inverseUpc, and
the txTrafficDescType is 6, 7, or 8, linear traffic shaping is enabled.
On ATM IP FPs, if this attribute is set to inverseUpc, and the
txTrafficDescType is 6, 7, or 8, inverse-UPC (also referred to as
VBR or dual leaky bucket) traffic shaping is enabled. Inverse-UPC
traffic shaping can burst above the sustained cell rate to the peak
cell rate for the duration defined by maximum burst size. Inverse-
UPC traffic shaping exactly conforms to the requirements of a dual
leaky bucket UPC enforcer.
When this attribute is set to enabled and the txTrafficDescType is 3,
4, 5, 6, 7, or 8, traffic shaping for a connection is enabled using
linear shaping.
Enabling or disabling traffic shaping may require a matching
change to the emissionPriority attribute and
unshapedTransmitQueueing attribute for this service category.

atmIfCARtVbrShapeRecoupPolicyThis attribute specifies the shaping recoup policy for the rt-VBR
service category. This is the policy which is used to recoup shaping
opportunities which are lost when more than one connection
schedules a cell for the same transmit opportunity. In this case, one
connection is scheduled, and the cell from another connection is
delayed by one cell time. This attribute affects how the transmit
time is calculated for the next cell on the delayed connection. This
attribute is ignored if this service category is not shaped.
When the connection which was delayed schedules the next cell to
transmit, it may calculate the time as a difference from either the
previous actual cell transmit time, or the time when the previous
cell should have been transmitted.
Setting this attribute to maximumEfficiency results in each
connection trying to recoup or regain delays in scheduling. The
transmit time from the next cell is calculated from the time when
the cell should originally have been sent. Cell delay variation
(CDV) occurs in this case since the cells are sent with less than the
shaping delay between them. However, in general the shaper
recovers (recoups) lost opportunities and improves efficiency.
Setting this attribute to minimumCdv results in connections not
trying to recoup or regain any delays in scheduling. The transmit
time for the next cell is calculated from the time when the previous
cell was actually transmitted. This minimizes CDV, but results in
missed cell opportunities.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.114.3.3.100.1.87 |
atmIfCARtVbrUnshapedTransmitQueueingThis attribute specifies the default queuing option for unshaped
connections of the rt-VBR service category. This attribute controls
whether common or per-VC queueing is used.
Per-VC queueing means that each connection has its own buffering
and queue limits.
Common queueing means that cells are queued in First In First Out
order on a common queue for this service category. The common
queue has one set of congestion control levels for all cells enqueued
on it.
For ATM IP cards, if traffic shaping for this service category is
disabled, this attribute may take any of the three values. In this case,
the value autoConfigure is interpreted to mean per-VC queueing.
For ATM IP cards, if traffic shaping for this service category is not
disabled, the only permitted values are perVc and autoConfigure.
In this case, the result is that all connections use per-VC queueing.
For CQC-based ATM cards, if the perVcQueueInterfaces attribute
of the Lp Eng Arc Cqc component permits shaping for this
interface, then this attribute may take any of the three values. In this
case, the value autoConfigure is interpreted to mean per-VC
queueing.
For CQC-based ATM cards, if the perVcQueueInterfaces attribute
of the Lp Eng Arc Cqc component does not permit shaping for this
interface, then this attribute may take values common or
autoConfigure. In this case, the value autoConfigure is interpreted
to mean common queueing.
If this attribute is set to autoConfigure, an override to this default
may be specified for a provisioned connection under the Vcd Tm or
Vpd Tm component.
The opUnshapedTransmitQueueing attribute of this component
indicates whether the transmit queueing is perVc or common.

atmIfCARtVbrUsageParameterControlThis attribute specifies the default usage parameter control (UPC)
option for connections of the rt-VBR service category. This attribute
is ignored if the rxTrafficDescriptorType indicates 1 or 2. An
override to this default may be specified for a provisioned
connection under the Vcd Tm or Vpd Tm component.
When this attribute is set to enforced, UPC is enforced for each
connection. When UPC is enforced, non-conforming cells are either
tagged or discarded depending on the rxTrafficDescriptorType.
On ATM IP FPs, when this attribute is set to monitored, UPC
conformance checking is performed, except, instead of the non-
conforming cells being tagged or discarded, they are merely
counted in the UPC violations counts, and passed on unchanged.
On CQC-based ATM FPs, when this attribute is set to monitored, it
has the same effect as setting it to disabled.
When this attribute is set to disabled, UPC is disabled on the receive
path for all rt-VBR connections.

atmIfCARtVbrWeightPolicyThis attribute specifies the policy which is applied when calculating
the fairness weight for unshaped connections of the rt-VBR service
category. The fairness weight for a connection determines the
relative amount of bandwidth which that connection obtains,
compared to other connections in the same service category.
Connections with equal weight get equal transmit opportunities.
Connections with higher weights get more transmit opportunities
compared with connections that have lower weights. An override to
this default may be specified for a provisioned connection under the
Vcd Tm or Vpd Tm component.
The fairness weight for a connection is directly proportional to the
value of one of the traffic descriptor parameters for that connection.
This attribute specifies which traffic descriptor parameter is used for
connections of the rt-VBR service category.
This attribute is ignored on CQC-based ATM cards. This attribute is
also ignored on ATM IP cards if unshapedTransmitQueueing is set
for common queuing.
If this attribute is set to scr, the fairness weight is proportional to the
transmit sustained cell rate (SCR) of a connection. Connections
with a higher SCR have a higher fairness weight. For connections
with txTrafficDescType 3, which have no SCR, the sustained cell
rate is assumed to be equal to the peak cell rate.
If this attribute is set to pcr, the fairness weight is proportional to
the transmit peak cell rate (PCR) of a connection. Connections with
a higher PCR have a higher fairness weight. Connections with
txTrafficDescType 1 or 2 get a minimum weight, which is 1.
If this attribute is set to ecr, the fairness weight is proportional to
the equivalent cell rate (ECR) of a connection as calculated by
connection admission control (CAC). Connections with a higher
ECR have a higher fairness weight. Connections with an ECR of 0
get a minimum weight, which is 1.
The weight of a connection is visible in the Vcc Tm, Vpc Tm, or Vpt
Tm weight attribute.

(CLP=1) of all cells for all rt-VBR connections. An override to this
default may be specified for a provisioned connection under the Vcd

When this attribute is set to enabled, CLP is set to 1 for all cells in
the transmit direction. Force tagging is only supported on ATM IP
FPs.
On CQC-based ATM FPs, this attribute must be set to disabled.
When this attribute is set to disabled, CLP is unchanged for all cells

txPacketWiseDiscard feature must specify a transmit queue limit
which is at least 5.71 times this offset. This ensures that the derived
Epd threshold will never be less than 17.5 % of the transmit queue

support the non-real-time variable bit rate (nrt-VBR) service
category except for connections managed by a Vpt CA. The
percentage of link capacity reserved for the given bandwidth pool is
the maximum bandwidth that can be allocated to nrt-VBR traffic.

atmIfCANrtVbrCdvtThis attribute specifies the default cell delay variation tolerance
(CDVT) for all connections of the nrt-VBR service category. An
override to this default may be specified for a provisioned
connection under the Vcd Tm or Vpd Tm component.
If Usage Parameter Control (UPC) is enabled for a connection,
CDVT is used by the UPC function to decide whether a cell is
conforming or non-conforming based on the connection's traffic
descriptor type. The larger the CDVT value, the more tolerant is the
UPC of bandwidth usage beyond the traffic contract.rw Unsigned32 .1.3.6.1.4.1.3764.1.1.30.114.3.4.100.1.2 |
atmIfCANrtVbrCellLossRatioThis attribute specifies the tolerable cell loss ratio (CLR) for nrt-
VBR traffic except for connections managed by a Vpt CA. The
number is the negative logarithm (base 10) of the CLR. In other
words if the target CLR = 1E-10 then NrtVbr cellLossRatio = 10.
This number must be greater than or equal to RtVbr cellLossRatio
since rt-VBR traffic has a higher discard priority. The NrtVbr
cellLossRatio is used by the Connection Admission Control (CAC)
algorithm to compute the required (equivalent) cell rate for nrt-VBR
connections.
There is a trade-off between the service category CLR and the
achievable link utilization. To guarantee an excellent service
category, the CLR should be as small as possible (e.g., 1E-10).
However, a smaller CLR results in a larger equivalent cell rate for a
given connection and hence a lower link utilization.
Setting this attribute to 0 means that a CLR of 1 can be tolerated. In
this case no bandwidth is reserved for nrt-VBR connections, and
CAC is effectively turned off. All nrt-VBR connections are
admitted.rw Unsigned32 .1.3.6.1.4.1.3764.1.1.30.114.3.4.100.1.3 |
atmIfCANrtVbrTxQueueLimitThis attribute specifies the default maximum queue length for the
emission queues used to buffer the traffic of the nrt-VBR service
category. It is used as the basis for setting the discard thresholds on
both common and per-VC queues. For the common queue, the
discard thresholds are set at approximately 35, 75, and 90 percent of
the value of this attribute for traffic at discard priority 3 (DP=3),
DP=2, and DP=1 respectively.
For per-VC queue, the actual limit may be reduced depending on
the shaping rate of the connection (for standard Vpt Vccs, this is the
shaping rate of the Vpt). The discard thresholds are set at
approximately 35, 75, and 90 percent of the scaled queue limit for
traffic at discard priority 3 (DP=3), DP=2, and DP=1 respectively.
However, a reduction will never result in a value that is less than the
value set for the minPerVcQueueLimit attribute.
When the value of this attribute is autoConfigure, an appropriate
value is selected based on the card type. It is set to 1792 for low
speed cards such as DS1, E1, and IMA, set to 2304 for high speed
CQC-based ATM cards such as JT2, DS3, E3 and OC3, and set to
10240 for high speed ATM IP cards such as 3pDS3Atm2,
3pE3Atm2, 2pOC3SmAtm2 and 2pOC3MmAtm2.
For ATM IP FPs, the per-VC queue limit may be overridden for a
permanent connection by specifying a value in the Vcd Tm or Vpd
Tm txQueueLimit attribute.
On CQC-based ATM cards, this attribute must be set to the same
value for CA NrtVbr, Abr and Ubr components.
The operational value of the maximum length of a queue (common
or per-VC) is indicated by the Vcc Tm, Vpc Tm, or Vpt Tm

atmIfCANrtVbrMinPerVcQueueLimitThis attribute specifies the minimum queue limit for the per-VC
queues of connections of the nrt-VBR service category.
The queue limit of a per-VC queue is obtained by scaling down the
txQueueLimit based on the shaping rate of that queue (shaping rate
for the connection, and for standard Vpt Vccs, the shaping rate of
the Vpt). This produces a constant delay for various queue lengths.

atmIfCANrtVbrTrafficShapingThis attribute specifies the default traffic shaping option for
connections of the nrt-VBR service category. An override to this
default may be specified for a provisioned connection under the Vcd
Tm or Vpd Tm component.
When this attribute is set to disabled, traffic shaping cannot be
enabled for any nrt-VBR connections.
For CQC-based ATM cards, this attribute may be set to enabled
only if the interface supports shaping, as defined by the
perVcQueueInterfaces attribute in the AtmResourceControl Cqc
Override component. If that component does not exist, this attribute
must be set to disabled.
If the Vcc Tm, Vpc Tm, or Vpt Tm txTrafficDescType indicates type
1 or 2, this attribute is ignored, and traffic shaping is not applicable
for that connection.
When this attribute is set to inverseUpc, traffic shaping for a
connection is enabled according to card type and the value of the
Vcc Tm, Vpc Tm, or Vpt Tm txTrafficDescType.
If this attribute is set to inverseUpc, and the txTrafficDescType is 3,
4, or 5, linear traffic shaping is enabled. Linear traffic shaping uses
a single static traffic shaping rate.
On CQC-based ATM FPs, if this attribute is set to inverseUpc, and
the txTrafficDescType is 6, 7, or 8, linear traffic shaping is enabled.
On ATM IP FPs, if this attribute is set to inverseUpc, and the
txTrafficDescType is 6, 7, or 8, inverse-UPC (also referred to as
VBR or dual leaky bucket) traffic shaping is enabled. Inverse-UPC
traffic shaping can burst above the sustained cell rate to the peak
cell rate for the duration defined by maximum burst size. Inverse-
UPC traffic shaping exactly conforms to the requirements of a dual
leaky bucket UPC enforcer.
When this attribute is set to enabled and the txTrafficDescType is 3,
4, 5, 6, 7, or 8, traffic shaping for a connection is enabled using
linear shaping.
Enabling or disabling traffic shaping may require a matching
change to the emissionPriority attribute and
unshapedTransmitQueueing attribute for this service category.

atmIfCANrtVbrShapeRecoupPolicyThis attribute specifies the shaping recoup policy for the nrt-VBR
service category. This is the policy which is used to recoup shaping
opportunities which are lost when more than one connection
schedules a cell for the same transmit opportunity. In this case, one
connection is scheduled, and the cell from the other connection is
delayed by one cell time. This attribute affects how the transmit
time is calculated for the next cell on the delayed connection. This
attribute is ignored if this service category is not shaped.
When the connection which was delayed schedules the next cell to
transmit, it may calculate the time as a difference from either the
previous actual cell transmit time, or the time when the previous
cell should have been transmitted.
Setting this attribute to maximumEfficiency results in each
connection trying to recoup or regain any delays in scheduling. The
transmit time from the next cell is calculated from the time when
the cell should originally have been sent. Cell delay variation
(CDV) occurs in this case since the cells are sent with less than the
shaping delay between them. However, in general the shaper
recovers (recoups) lost opportunities and improves efficiency.
Setting this attribute to minimumCdv results in connections not
trying to recoup or regain any delays in scheduling. The transmit
time for the next cell is calculated from the time when the previous
cell was actually transmitted. This minimizes CDV, but results in
missed cell opportunities.

atmIfCANrtVbrUnshapedTransmitQueueingThis attribute specifies the default queuing option for unshaped
connections of the nrt-VBR service category. This attribute controls
whether common or per-VC queueing is used.
Per-VC queueing means that each connection has its own buffering
and queue limits.
Common queueing means that cells are queued in First In First Out
order on a common queue. The common queue has one set of
congestion control levels for all cells enqueued on it. For ATM IP
cards, there is one common queue for the nrt-VBR service category.
For CQC-based ATM cards, there is one common queue which is
shared by the nrt-VBR, ABR and UBR service categories.
For ATM IP cards, if traffic shaping for this service category is
disabled, this attribute may take any of the three values. In this case,
the value autoConfigure is interpreted to mean per-VC queueing.
For ATM IP cards, if traffic shaping for this service category is not
disabled, the only permitted values are perVc and autoConfigure.
In this case, the result is that all connections use per-VC queueing.
For CQC-based ATM cards, if the perVcQueueInterfaces attribute
of the Lp Eng Arc Cqc component permits shaping for this
interface, then this attribute may take any of the three values. In this
case, the value autoConfigure is interpreted to mean per-VC
queueing.
For CQC-based ATM cards, if the perVcQueueInterfaces attribute
of the Lp Eng Arc Cqc component does not permit shaping for this
interface, then this attribute may take the values common or
autoConfigure. In this case, the value autoConfigure is interpreted
to mean common queueing.
If this attribute is set to autoConfigure, an override to this default
may be specified for a provisioned connection under the Vcd Tm or
Vpd Tm component.
The opUnshapedTransmitQueueing attribute of this component
indicates whether the transmit queueing is perVc or common.

atmIfCANrtVbrUsageParameterControlThis attribute specifies the default usage parameter control (UPC)
option for connections of the nrt-VBR service category. This
attribute is ignored if the rxTrafficDescriptorType indicates 1 or 2.
An override to this default may be specified for a provisioned
connection under the Vcd Tm or Vpd Tm component.
When this attribute is set to enforced, UPC is enabled for each
connection. When UPC is enforced, non-conforming cells are either
tagged or discarded depending on the rxTrafficDescriptorType.
On ATM IP FPs, when this attribute is set to monitored, UPC
conformance checking is performed, except, instead of the non-
conforming cells being tagged or discarded, they are merely
counted in the UPC violations counts, and passed on unchanged.
On CQC-based ATM FPs, when this attribute is set to monitored, it
has the same effect as setting it to disabled.
When this attribute is set to disabled, UPC is disabled on the receive
path for all nrt-VBR connections.

atmIfCANrtVbrWeightPolicyThis attribute specifies the policy which is applied when calculating
the fairness weight for unshaped connections of the nrt-VBR
service category. The fairness weight for a connection determines
the relative amount of bandwidth which that connection obtains,
compared to other connections in the same service category.
Connections with equal weight get equal transmit opportunities.
Connections with higher weights get more transmit opportunities
compared with connections that have lower weights. An override to
this default may be specified for a provisioned connection under the
Vcd Tm or Vpd Tm component.
The fairness weight for a connection is directly proportional to the
value of one of the traffic descriptor parameters for that connection.
This attribute specifies which traffic descriptor parameter is used for
connections of the nrt-VBR service category.
This attribute is ignored on CQC-based ATM cards. This attribute is
also ignored on ATM IP cards if unshapedTransmitQueueing is set
for common queuing.
If this attribute is set to scr, the fairness weight is proportional to the
transmit sustained cell rate (SCR) of a connection. Connections
with a higher SCR have a higher fairness weight. For connections
with txTrafficDescType 3, which have no SCR, the sustained cell
rate is assumed to be equal to the peak cell rate.
If this attribute is set to pcr, the fairness weight is proportional to
the transmit peak cell rate (PCR) of a connection. Connections with
a higher PCR have a higher fairness weight. Connections with
txTrafficDescType 1 or 2 get a minimum weight, which is 1.
If this attribute is set to ecr, the fairness weight is proportional to
the equivalent cell rate (ECR) of a connection as calculated by
connection admission control (CAC). Connections with a higher
ECR have a higher fairness weight. Connections with an ECR of 0
get a minimum weight, which is 1.
The weight of a connection is visible in the Vcc Tm, Vpc Tm, or Vpt
Tm weight attribute.

(CLP=1) of all cells for all nrt-VBR connections. An override to
this default may be specified for a provisioned connection under the
Vcd Tm or Vpd Tm component.
When this attribute is set to enabled, CLP is set to 1 for all cells in
the transmit direction. Force tagging is only supported on ATM IP
FPs.
On CQC-based ATM FPs, this attribute must be set to disabled.
When this attribute is set to disabled, CLP is unchanged for all cells

atmIfCANrtVbrEpdOffsetThis attribute indicates the Early Packet Discard (EPD) offset which
is currently in use for this service category. The EPD offset is used
to derive the EPD thresholds for each CC level.
Any connection under this service category which requires the
txPacketWiseDiscard feature must specify a transmit queue limit
which is at least 5.71 times this offset. This ensures that the derived
Epd threshold will never be less than 17.5 % of the transmit queue

atmIfCAAbrTxQueueLimitThis attribute specifies the default maximum queue length for the
emission queues used to buffer the traffic of the ABR service
category. It is used as the basis for setting the discard thresholds on
ABR per-VC queues.
For per-VC queue, the actual limit may be reduced depending on
the peak cell rate. The discard thresholds are set at approximately
35, 75 and 90 percent of the scaled queue limit for traffic at discard
priority 3 (DP=3), DP=2 and DP=1 respectively. However, a
reduction will never result in a value that is less than the value set
for the minPerVcQueueLimit attribute.
When the value of this attribute is autoConfigure, an appropriate
value is selected based on the card type. It is set to 1792 for low
speed cards such as DS1, E1 and IMA, set to 2304 for high speed
CQC-based ATM cards such as JT2, DS3, E3 and OC3, and set to
10240 for high speed ATM IP cards such as 3pDS3Atm2,
3pE3Atm2, 2pOC3SmAtm2 and 2pOC3MmAtm2.
On CQC-based ATM cards, this attribute must be set to the same
value for CA NrtVbr, Abr and Ubr components.
For ATM IP FPs, the per-VC queue limit may be overridden for a
permanent connection by specifying a value in the Vcd Tm or Vpd
Tm txQueueLimit attribute.
The operational value of the maximum length of a queue (common
or per-VC) is indicated by the Vcc Tm, Vpc Tm, or Vpt Tm

atmIfCAAbrMinPerVcQueueLimitThis attribute specifies the minimum queue limit for the per-VC
queues of connections of the ABR service category.
The queue limit of a per-VC queue is obtained by scaling down the
txQueueLimit based on the peak cell rate of that queue. This
produces a constant delay for various queue lengths. The
txQueueLimit provides an upper bound while minPerVcQueueLimit
provides the lower bound. The value of this attribute must not be
greater than the value of the txQueueLimit attribute. If this service
category is used by Trunks the value of minPerVcQueueLimit must
be at least 88.
On CQC-based ATM cards, this attribute must be set to the same
value for CA NrtVbr, Abr and Ubr components.
For Vpts, this attribute does not apply. Regardless of Vpt service
category, standard Vpts always use the AtmIf Ca NrtVbr
minPerVcQueueLimit value as their default. To determine the queue
limit of a standard Vpt Vcc, the txQueueLimit is scaled down by the

atmIfCAAbrEmissionPriorityThis attribute is not applicable and is ignored for CQC-based ATM
cards.
This attribute specifies the emission priority (EP) which is used to
transmit traffic of the ABR service category. A lower numerical
value for this attribute specifies a higher emission priority. 0 is the
highest EP and 7 is the lowest. Cells at a higher emission priority
receive higher preference for link bandwidth. EPs 0 and 1 are in the
absolute priority range, and are unaffected by any minimum
bandwidth guarantees. EPs 2 through 7 are in the guaranteed
bandwidth range. Minimum bandwidth guarantee is specified in the
AtmIf/n Ep/m component.
Emission priority setting must comply with all of the following
constraints:
1. The emission priority numbers must be in the following order:
CBR <= rt-VBR <= nrt-VBR <= ABR <= UBR
2. Two different ATM service categories may share the same EP
only if they are both shaped.
3. CBR and rt-VBR may be placed either in the absolute priority
range (EP 0 or 1) or in the guaranteed bandwidth range (EP 2
through 7).
4. If both CBR and rt-VBR are shaped, rt-VBR must share the
same EP with CBR or ABR. If either one of CBR or rt-VBR are
not shaped, then they cannot share the same EP.
5. ABR service category is always deemed to be shaped. If nrt-VBR
is shaped, it must share the same EP with ABR. If nrt-VBR is not
shaped it must have a higher EP than ABR.

performing explicit rate calculations. Each ABR connection is
assigned a weight. Connections with a higher weight get a greater
proportion of the available ABR bandwidth compared with
connections that have lower weights. This attribute is ignored on
CQC-based ATM cards.
If the value is mcr, the congestion fairness weight is based on the
Minimum Cell Rate (MCR) of the connection.
If the value is pcr, the congestion fairness weight is based on the
Peak Cell Rate (PCR) of the connection.
If the value is pcrMinusMcr, the congestion fairness weight is
based on the difference between the Peak Cell Rate and the

atmIfCAAbrFrttPortionThis attribute specifies the portion of the Fixed Round Trip Time
(FRTT) which is added to each ABR call setup which traverses this
interface. The FRTT for the entire call is the sum of the FRTT
portions for each interface traversed by the call. FRTT is used by
the ABR Source or Virtual Source to adjust the value of ICR
according to the rules specified in the ATM Forum TM Version 4.0
specification.
The frttPortion includes propagation delay through the physical
media, plus delays included by the transmission system, plus fixed

atmIfCAAbrAbrConnectionTypeThis attribute specifies the default type for ABR connections. It may
be overridden by the abrConnectionType attribute under the Vcd Tm
or Vpd Tm component, or by other configuration options. For
example, for ABR end point connections originating at this switch,
the Vcc Tm abrConnectionType will show sourceDest regardless of
the setting of this attribute.
If this attribute is set to abrSwitch, traversing ABR connections
default either to erSwitch or to efciSwitch, depending on the card
type and connection type. If the interface to which traffic is directed
across the backplane is configured as type virtualSourceDest and
this is a ATM IP FP, then connection points under this AtmIf are
activated as type virtualSourceDest.
If this attribute is set to virtualSourceDest, traversing ABR
connections may be instantiated as one of the following types:
erSwitch, efciSwitch, or virtualSourceDest. A Virtual Source-
Virtual Destination (VS/VD) boundary forms a break in the end to
end flow of RM cells as defined in the ATM Forum Specification for
Traffic Management Version 4.0. On ATM IP cards, a VS/VD
boundary can be configured for a connection providing all of the
following conditions are met:
1. the ABR connection is traversing (not terminating at) this
interface;
2. both this interface and next hop interface to which traffic is
directed across the backplane are located on ATM IP cards;
3. one or both connecting points are configured as
virtualSourceDest,
4. the next hop interface to which traffic is directed across the
backplane is not configured as nonAbrInterworking,
5. the connection is not a Vcc under a standard VPT.
If this attribute is set to nonAbrInterworking, this interface is
defined as a point of interworking between an ABR and a non-ABR
connection. In this case the next hop interface to which traffic is
directed across the backplane is activated as type sourceDest.
The Vcc or Vpc Tm abrConnectionType operational attribute

the Minimum Cell Rate (MCR) for the connection.
When this attribute is set to usePcr, ICR is set to the same value as
the Peak Cell Rate (PCR) for the connection.
When this attribute is set to some explicit number, that number is

atmIfCAAbrRateDecreaseFactorThis attribute specifies the default Rate Decrease Factor (RDF) for
ABR connections. An override to this default may be specified for a
provisioned connection under the Vcd Tm Abr or Vpd Tm Abr

The RDF value is computed by using the provisioned value of this
attribute, n, as 2 to the inverse power n. For example, if the value of
this attribute is 8, RDF is 2E-8 = 1/256.
RDF controls the amount by which the cell transmission rate may
decrease upon receipt of a backward Resource Management (B-
RM) cell. For example, if a backward RM cell is received with the
Congestion Indication (CI) field set to 1, the Allowed Cell Rate
(ACR) value would be reduced by the amount (RDF*ACR). The
ACR is not allowed to fall below the Minimum Cell Rate (MCR), in

ABR connections. An override to this default may be specified for a
provisioned connection under the Vcd Tm Abr or Vpd Tm Abr

Element.
The RIF value is computed by using the provisioned value of this
attribute, n, as 2 to the inverse power n. For example, if the value of
this attribute is 6, RIF is 2E-6 = 1/64.
RIF controls the amount by which the cell transmission rate may
increase upon receipt of a backward Resource Management (B-RM)
cell. For example, if a backward RM cell is received with the
Congestion Indication (CI) and the No Increase (NI) fields both set

atmIfCAAbrMaxCellPerRmCellThis attribute specifies the default number of user cells per
Resource Management cell (NRM) for ABR connections. An
override to this default may be specified for a provisioned
connection under the Vcd Tm Abr or Vpd Tm Abr component, or
signalled as the NRM parameter in the ABR Additional Parameters
Information Element.
NRM is the maximum number of cells an ABR source may transmit
for each forward Resource Management (F-RM) cell. The count of
the cells transmitted includes user cells, OAM cells, backward RM
cells, and the forward RM cell.
Note that a value of 2 is not recommended even though it is
permitted according to the ATM Forum standard. When this
attribute is set to a value of 2, it is possible that only one forward
and one backward RM cell are repeatedly transmitted, and all data
traffic is queued up indefinitely.
This attribute is ignored under all conditions where the Vcc Tm or
Vpc Tm operational attribute abrConnectionType indicates
explicitRateMarking.rw Unsigned32 (2 | 4 | 8 | 16 | 32 | 64 | 128 | 256) .1.3.6.1.4.1.3764.1.1.30.114.3.5.100.1.26 |
atmIfCAAbrMaxTimeBetweenRmCellsThis attribute specifies the default time between Resource
Management cells (TRM) for ABR connections. An override to this
default may be specified for a provisioned connection under the Vcd
Tm Abr or Vpd Tm Abr component, or signalled in the ABR
Additional Parameters Information Element.
TRM provides an upper bound on the time interval between forward
Resource Management (F-RM) cells for an ABR source. Since the
last F-RM cell was sent, if at least TRM time has elapsed and at
least 2 other cells have been sent, the next cell to be transmitted
would be a forward RM cell.
This attribute is ignored under all conditions where the Vcc Tm or
Vcd Tm operational attribute abrConnectionType is displayed as
erSwitch.

atmIfCAAbrCutoffDecreaseFactorThis attribute specifies the default Cutoff Decrease Factor (CDF)
parameter for ABR connections. An override to this default may be
specified for a provisioned connection under the Vcd Tm Abr or Vpd
Tm Abr component, or signalled in the ABR Additional Parameters
Information Element.
When the value of this attribute is non-zero, CDF is computed as
the inverse of the value. For example, if the value is 32, the value of
CDF is 1/32. When the value of this attribute is 0, CDF is also zero.
CDF controls the decrease in the Allowed Cell Rate (ACR)
associated with the CRM parameter. CRM is the limit of the
number of forward Resource Management (F-RM) cells which may
be sent in the absence of received backward RM cells. When this
limit is crossed, the ACR value would be decreased by the amount
(CDF*ACR). The ACR is not allowed to fall below the MCR, in
which case the ACR is set to MCR.rw Unsigned32 (0 | 1 | 2 | 4 | 8 | 16 | 32 | 64) .1.3.6.1.4.1.3764.1.1.30.114.3.5.100.1.28 |
atmIfCAAbrAcrDecreaseTimeFactorThis attribute specifies the default Allowed Cell Rate Decrease
Time Factor (ADTF) parameter for ABR connections. An override
to this default may be specified for a provisioned connection under
the Vcd Tm Abr or Vpd Tm Abr component, or signalled in the ABR
Additional Parameters Information Element.
ADTF is the time interval permitted between sending forward
Resource Management (F-RM) cells before the Allowed Cell Rate
(ACR) is decreased to the Initial Cell Rate (ICR). In other words, if
the source does not transmit a forward RM cell for a period of
ADTF centi-seconds (hundredths of a second), it will reduce its
ACR to the value of its ICR. If ACR is already at or below ICR,
further rate reductions are defined by the CRM ABR parameter.rw Unsigned32 .1.3.6.1.4.1.3764.1.1.30.114.3.5.100.1.29 |
atmIfCAAbrDgcraMaximumDelayThis attribute specifies the default maximum delay for Dynamic
General Cell Rate Algorithm (DGCRA) rate changes for ABR
connections. An override to this default may be specified for a
provisioned connection under the Vcd Tm Abr or Vpd Tm Abr
component.
This attribute specifies an upper bound on the delay after which the
rate change induced by a backward Resource Management (B-RM)
cell departing from this interface (in the backward direction) is
expected to be observed at the interface (in the forward connection).
This upper bound may be approximated as the round trip sum of the
fixed and propagation delays and the maximum queueing delays
between the ABR source and this interface.
The value of this attribute is used in policing an ABR connection
using the DGCRA. A larger value for this attribute implies a more
lenient policer. When there is a decrease in the Allowed Cell Rate
(ACR), the policer waits a correspondingly longer period of time
before it enforces the new cell rate.
The value of this attribute must be greater than or equal to
dgcraMinimumDelay, since the maximum delay must be greater
than or equal to the minimum delay.rw Unsigned32 .1.3.6.1.4.1.3764.1.1.30.114.3.5.100.1.30 |
atmIfCAAbrDgcraMinimumDelayThis attribute specifies the default minimum delay for Dynamic
General Cell Rate Algorithm (DGCRA) rate changes for ABR
connections. An override to this default may be specified for a
provisioned connection under the Vcd Tm Abr or Vpd Tm Abr
component.
This attribute specifies a lower bound on the delay after which the
rate change induced by a backward Resource Management (B-RM)
cell departing from this interface (in the backward direction) is
expected to be observed at the interface (in the forward connection).
This lower bound may be approximated as the round trip sum of the
fixed and propagation delays between the ABR source and this
interface.
The value of this attribute is used in policing an ABR connection
using the DGCRA. A smaller value for this attribute implies a more
lenient policer. When there is an increase in the Allowed Cell Rate
(ACR), the policer waits for a correspondingly shorter period of
time before it enforces the new cell rate.
The value of this attribute must be less than or equal to
dgcraMaximumDelay, since the maximum delay must be greater
than or equal to the minimum delay.rw Unsigned32 .1.3.6.1.4.1.3764.1.1.30.114.3.5.100.1.31 |
atmIfCAAbrHoldingPriorityThis attribute specifies the default holding priority which applies to
SVP and SVC ABR connections. It takes a value from 0 (highest
priority) to 4 (lowest priority). In a situation where the link
bandwidth fluctuates, such as over an IMA link, holding priority is
used to determine which connections are held and which are
released. Holding priority 4 connections are the first to be released.
Holding priority 0 connections are the last to be released.
This attribute does not apply to Vpt Vccs. When bandwidth
fluctuates, the entire Vpt, along with all Vpt Vccs is released as a
unit, according to the Vpt's holdingPriority.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.114.3.5.100.1.32 |

atmIfCAAbrEpdOffsetThis attribute indicates the Early Packet Discard (EPD) offset which
is currently in use for this service category. The EPD offset is used
to derive the EPD thresholds for each CC level.
Any connection under this service category which requires the
txPacketWiseDiscard feature must specify a transmit queue limit
which is at least 5.71 times this offset. This ensures that the derived
Epd threshold will never be less than 17.5 % of the transmit queue
limit. If this is not done, txPacketWiseDiscard for the connection
will be automatically disabled.

atmIfCAUbrPoolThis attribute specifies the bandwidth pool which is to be used to
support the unspecified bit rate (UBR) service category except for
connections managed by a Vpt CA. The percentage of link capacity
reserved for the given bandwidth pool is the maximum bandwidth
that can be allocated to UBR traffic. The percentage allocated to
each bandwidth pool can be provisioned through the bandwidthPool
attribute under the CA.
The amount of bandwidth reserved for each UBR connection is

atmIfCAUbrMinimumCellRateThis attribute specifies the minimum cell rate (MCR) which is
allocated from the UBR bandwidth pool for each UBR connection
which is admitted using Connection Admission Control (CAC)
except for connections managed by a Vpt CA. UBR connections
normally are serviced on a best effort basis, but this attribute allows

atmIfCAUbrTxQueueLimitThis attribute specifies the default maximum queue length for the
emission queues used to buffer the traffic of the UBR service
category. It is used as the basis for setting the discard thresholds on
both common and per-VC queues. For the common queue, the
discard thresholds are set at approximately 35, 75 and 90 percent of
the value of this attribute for traffic at discard priority 3 (DP=3),
DP=2 and DP=1 respectively.
For per-VC queue, the actual limit may be reduced depending on
the shaping rate of the connection (for standard Vpt Vccs, this is the
shaping rate of the Vpt). The discard thresholds are set at
approximately 35, 75 and 90 percent of the scaled queue limit for
traffic at discard priority 3 (DP=3), DP=2 and DP=1 respectively.
However, a reduction will never result in a value that is less than the
value set for the minPerVcQueueLimit attribute.
When the value of this attribute is autoConfigure, an appropriate
value is selected based on the card type. It is set to 1792 for low
speed cards such as DS1, E1 and IMA, set to 2304 for high speed
CQC-based ATM cards such as JT2, DS3, E3 and OC3, and set to
10240 for high speed ATM IP cards such as 3pDS3Atm2,
3pE3Atm2, 2pOC3SmAtm2 and 2pOC3MmAtm2.
On CQC-based ATM cards, this attribute must be set to the same
value for CA NrtVbr, Abr and Ubr components.
For ATM IP FPs, the per-VC queue limit may be overridden for a
permanent connection by specifying a value in the Vcd Tm or Vpd
Tm txQueueLimit attribute.
The operational value of the maximum length of a queue (common
or per-VC) is indicated by the Vcc Tm, Vpc Tm, or Vpt Tm
txQueueThresholds attribute.
For standard Vpts, this attribute does not apply when using per-VC
queuing and only applies when using common queueing. When
using per-VC queueing, regardless of the Vpt's service category,
standard Vpts use the AtmIf Ca NrtVbr txQueueLimit value as their
default.

atmIfCAUbrMinPerVcQueueLimitThis attribute specifies the minimum queue limit for the per-VC
queues of connections of the UBR service category.
The queue limit of a per-VC queue is obtained by scaling down the
txQueueLimit based on the shaping rate of that queue (shaping rate
for the connection, and for standard Vpt Vccs, the shaping rate of
the Vpt). This produces a constant delay for various queue lengths.
The txQueueLimit provides an upper bound while
minPerVcQueueLimit provides the lower bound. The value of this
attribute must not be greater than the value of the txQueueLimit
attribute. If this service category is used by Trunks the value of
minPerVcQueueLimit must be at least 88.
On CQC-based ATM cards, this attribute must be set to the same
value for CA NrtVbr, Abr and Ubr components.
For Vpts, this attribute does not apply. Regardless of Vpt service
category, standard Vpts always use the AtmIf Ca NrtVbr
minPerVcQueueLimit value as their default. To determine the queue
limit of a standard Vpt Vcc, the txQueueLimit is scaled down by the
Vpt shaping rate.rw Unsigned32 .1.3.6.1.4.1.3764.1.1.30.114.3.6.100.1.13 |
atmIfCAUbrPerVcQueueLimitReferenceRateThis attribute specifies the shaping rate to be used in computing the
tolerable delay for per-VC queues of connections of the UBR
service category. The delay is computed as the txQueueLimit
divided by the value of this attribute.
When the value of this attribute is autoConfigure, an appropriate
default is selected based on the card type. It is set to 3685 for low
speed cards such as DS1, E1 and IMA, set to 14740 for high speed

speed ATM IP cards such as 3pDS3Atm2, 3pE3Atm2,
2pOC3SmAtm2 and 2pOC3MmAtm2.
On CQC-based ATM cards, this attribute must be set to the same
value for CA NrtVbr, Abr and Ubr components.

atmIfCAUbrEmissionPriorityThis attribute is not applicable and is ignored for CQC-based ATM
cards.
This attribute specifies the emission priority (EP) which is used to
transmit traffic of the UBR service category. A lower numerical
value for this attribute specifies a higher emission priority. 0 is the
highest EP and 7 is the lowest. Cells at a higher emission priority
receive higher preference for link bandwidth. EPs 0 and 1 are in the
absolute priority range, and are unaffected by any minimum
bandwidth guarantees. EPs 2 through 7 are in the guaranteed
bandwidth range. Minimum bandwidth guarantee is specified in the
AtmIf/n Ep/m component.
Emission priority setting must comply with all of the following
constraints:
1. The emission priority numbers must be in the following order:
CBR <= rt-VBR <= nrt-VBR <= ABR <= UBR
2. Two different ATM service categories may share the same EP
only if they are both shaped.
3. CBR and rt-VBR may be placed either in the absolute priority
range (EP 0 or 1) or in the guaranteed bandwidth range (EP 2
through 7).
4. If both CBR and rt-VBR are shaped, rt-VBR must share the
same EP with CBR or ABR. If either one of CBR or rt-VBR are
not shaped, then they cannot share the same EP.
5. ABR service category is always deemed to be shaped. If nrt-VBR
is shaped, it must share the same EP with ABR. If nrt-VBR is not
shaped it must have a higher EP than ABR.
6. If UBR is shaped, it must share the same EP with ABR. If UBR
is not shaped, it must have a lower EP than ABR.

atmIfCAUbrTrafficShapingThis attribute specifies the default traffic shaping option for
connections of the UBR service category. An override to this default
may be specified for a provisioned connection under the Vcd Tm or
Vpd Tm component.
When this attribute is set to disabled, traffic shaping cannot be
enabled for any UBR connection.
For CQC-based ATM cards, this attribute may be set to enabled
only if the interface supports shaping, as defined by the
perVcQueueInterfaces attribute in the AtmResourceControl Cqc
Override component. If that component does not exist, this attribute
must be set to disabled.
If the Vcc Tm, Vpc Tm, or Vpt Tm txTrafficDescType indicates type
1 or 2, this attribute is ignored, and traffic shaping is not applicable
for that connection.
When this attribute is set to inverseUpc, traffic shaping for a
connection is enabled according to card type and the value of the
Vcc Tm, Vpc Tm, or Vpt Tm txTrafficDescType.
If this attribute is set to inverseUpc, and the txTrafficDescType is 3,
4, or 5, linear traffic shaping is enabled. Linear traffic shaping uses
a single static traffic shaping rate.
On CQC-based ATM FPs, if this attribute is set to inverseUpc, and
the txTrafficDescType is 6, 7, or 8, linear traffic shaping is enabled.
On ATM IP FPs, if this attribute is set to inverseUpc, and the
txTrafficDescType is 6, 7, or 8, inverse-UPC (also referred to as
VBR or dual leaky bucket) traffic shaping is enabled. Inverse-UPC
traffic shaping can burst above the sustained cell rate to the peak
cell rate for the duration defined by maximum burst size. Inverse-
UPC traffic shaping exactly conforms to the requirements of a dual
leaky bucket UPC enforcer.
When this attribute is set to enabled and the txTrafficDescType is 3,
4, 5, 6, 7, or 8, traffic shaping for a connection is enabled using
linear shaping.
Enabling or disabling traffic shaping may require a matching
change to the emissionPriority attribute and
unshapedTransmitQueueing attribute for this service category.

atmIfCAUbrShapeRecoupPolicyThis attribute specifies the shaping recoup policy for the UBR
service category. This is the policy which is used to recoup shaping
opportunities which are lost when more than one connection
schedules a cell for the same transmit opportunity. In this case, one
connection is scheduled, and the cell from the other connection is
delayed by one cell time. This attribute affects how the transmit
time is calculated for the next cell on the delayed connection. This
attribute is ignored if this service category is not shaped.
When the connection which was delayed schedules the next cell to
transmit, it may calculate the time as a difference from either the
previous actual cell transmit time, or the time when the previous
cell should have been transmitted.
Setting this attribute to maximumEfficiency results in each
connection trying to recoup or regain any delays in scheduling. The
transmit time from the next cell is calculated from the time when
the cell should originally have been sent. Cell delay variation
(CDV) occurs in this case since the cells are sent with less than the
shaping delay between them. However, in general the shaper
recovers (recoups) lost opportunities and improves efficiency.
Setting this attribute to minimumCdv results in connections not
trying to recoup or regain any delays in scheduling. The transmit
time for the next cell is calculated from the time when the previous
cell was actually transmitted. This minimizes CDV, but results in
missed cell opportunities.

atmIfCAUbrUnshapedTransmitQueueingThis attribute specifies the default queuing option for unshaped
connections of the UBR service category. This attribute controls
whether common or per-VC queueing is used.
Per-VC queueing means that each connection has its own buffering
and queue limits.
Common queueing means that cells are queued in First In First Out
order on a common queue. The common queue has one set of
congestion control levels for all cells enqueued on it. For ATM IP
cards, there is one common queue for the UBR service category.
For CQC-based ATM cards, there is one common queue which is
shared by the nrt-VBR, ABR and UBR service categories.
For ATM IP cards, if traffic shaping for this service category is
disabled, this attribute may take any of the three values. In this case,
the value autoConfigure is interpreted to mean per-VC queueing.
For ATM IP cards, if traffic shaping for this service category is not
disabled, the only permitted values are perVc and autoConfigure.
In this case, the result is that all connections use per-VC queueing.
For CQC-based ATM cards, if the perVcQueueInterfaces attribute
of the Lp Eng Arc Cqc component permits shaping for this
interface, then this attribute may take any of the three values. In this
case, the value autoConfigure is interpreted to mean per-VC
queueing.
For CQC-based ATM cards, if the perVcQueueInterfaces attribute
of the Lp Eng Arc Cqc component does not permit shaping for this
interface, then this attribute may take the values common or
autoConfigure. In this case, the value autoConfigure is interpreted
to mean common queueing.
If this attribute is set to autoConfigure, an override to this default
may be specified for a provisioned connection under the Vcd Tm or
Vpd Tm component.
The opUnshapedTransmitQueueing attribute of this component
indicates whether the transmit queueing is perVc or common.

atmIfCAUbrUsageParameterControlThis attribute specifies the default usage parameter control (UPC)
option for connections of the UBR service category. This attribute is
ignored if the rxTrafficDescriptorType indicates 1 or 2. An override
to this default may be specified for a provisioned connection under
the Vcd Tm or Vpd Tm component.
When this attribute is set to enforced, UPC is enforced for each
connection. When UPC is enforced, non-conforming cells are either
tagged or discarded depending on the rxTrafficDescriptorType.
On ATM IP FPs, when this attribute is set to monitored, UPC
conformance checking is performed, except, instead of the non-
conforming cells being tagged or discarded, they are merely
counted in the UPC violations counts, and passed on unchanged.
On CQC-based ATM FPs, when this attribute is set to monitored, it
has the same effect as setting it to disabled.
When this attribute is set to disabled, UPC is disabled on the receive
path for all UBR connections.

atmIfCAUbrWeightPolicyThis attribute specifies the policy which is applied when calculating
the fairness weight for unshaped connections of the UBR service
category. The fairness weight for a connection determines the
relative amount of bandwidth which that connection obtains,
compared to other connections in the same service category.
Connections with equal weight get equal transmit opportunities.
Connections with higher weights get more transmit opportunities
compared with connections that have lower weights. An override to
this default may be specified for a provisioned connection under the
Vcd Tm or Vpd Tm component.
The fairness weight for a connection is directly proportional to the
value of one of the traffic descriptor parameters for that connection.
This attribute specifies which traffic descriptor parameter is used for
connections of the UBR service category.
This attribute is ignored on CQC-based ATM cards. This attribute is
also ignored on ATM IP cards if unshapedTransmitQueueing is set

If this attribute is set to mcr, the fairness weight is proportional to
the default minimum cell rate (MCR) for UBR connections. If the
default minimum cell rate is 0, all UBR connections get a minimum
weight, which is 1.
If this attribute is set to pcr, the fairness weight is proportional to
the transmit peak cell rate (PCR) of a connection. Connections with
a higher PCR have a higher fairness weight. Connections with
txTrafficDescType 1 or 2 get a minimum weight, which is 1.
If this attribute is set to ecr, the fairness weight is proportional to
the equivalent cell rate (ECR) of a connection as calculated by
connection admission control (CAC). Connections with a higher
ECR have a higher fairness weight. Connections with an ECR of 0
get a minimum weight, which is 1.
The weight of a connection is visible in the Vcc Tm, Vpc Tm, or Vpt
Tm weight attribute.

atmIfCAUbrForceTaggingThis attribute specifies the default of whether to force tagging
(CLP=1) of all cells for all UBR connections. An override to this
default may be specified for a provisioned connection under the Vcd
Tm or Vpd Tm component.
When this attribute is set to enabled, CLP is set to 1 for all cells in
the transmit direction. This is in conformance with the ATM Forum
TM4.0 UBR.2 service definition. Force tagging is only supported
on ATM IP FPs.
On CQC-based ATM FPs, this attribute must be set to disabled.
When this attribute is set to disabled, CLP is unchanged for all cells

atmIfVpcVpdTmAbrTransientBufferExposureThis attribute specifies the Transient Buffer Exposure (TBE) for this
connection. TBE is the negotiated number of cells that the network
would like to limit the source to send during start-up periods, before
the first Resource Management (RM) cell returns.
TBE divided by fixedRoundTripTime determines an upper bound
for the operational value of initialCellRate, the rate at which a
source should send initially and after an idle period.
TBE divided by maxCellsPerRmCell specifies the operational value
of forwardRmCellLimit, the limit of the number of forward
Resource Management (RM) cells which may be sent in the
absence of received backward RM cells.

atmIfVpcVpdTmAbrFixedRoundTripTimeThis attribute specifies the Fixed Round-Trip Time (FRTT)
parameter for this connection. FRTT is the sum of the fixed and
propagation delays from the source to a destination and back.
The value of transientBufferExposure divided by the value of FRTT
(in seconds) determines an upper bound for the operational value of
initialCellRate, the rate at which a source should send initially and
after an idle period.
This attribute is ignored under all conditions where the operational
attribute abrConnectionType indicates erSwitch or efciSwitch.rw Unsigned32 .1.3.6.1.4.1.3764.1.1.30.114.4.2.2.2.110.1.12 |
atmIfVpcVpdTmAbrRateDecreaseFactorThis attribute specifies the Rate Decrease Factor (RDF) for this
connection. The RDF value is computed by using the provisioned
value of this attribute, n, as 2 to the inverse power n. For example, if
the value of this attribute is 8, RDF is 2E-8 = 1/256.
RDF controls the amount by which the cell transmission rate may
decrease upon receipt of a backward Resource Management (RM)
cell. For example, if a backward RM cell is received with the
Congestion Indication (CI) field set to 1, the Allowed Cell Rate
(ACR) value would be reduced by the amount (RDF*ACR). The
ACR is not allowed to fall below the Minimum Cell Rate (MCR), in
which case the ACR is set to MCR.
This attribute is ignored under all conditions where the operational
attribute abrConnectionType has the value erSwitch.

atmIfVpcVpdTmAbrRateIncreaseFactorThis attribute specifies the Rate Increase Factor (RIF) for this
connection. The RIF value is computed by using the provisioned
value of this attribute, n, as 2 to the inverse power n. For example, if
the value of this attribute is 6, RIF is 2E-6 = 1/64.
RIF controls the amount by which the cell transmission rate may
increase upon receipt of a backward Resource Management (RM)
cell. For example, if a backward RM cell is received with the
Congestion Indication (CI) and the No Increase (NI) fields both set
to 0, the Allowed Cell Rate (ACR) value would be increased by the
amount (RIF*ACR). The ACR is not allowed to exceed the Peak
Cell Rate (PCR), in which case the ACR is set to PCR.

atmIfVpcVpdTmAbrMaxCellPerRmCellThis attribute specifies the maximum number of cells an ABR
source may transmit for each forward Resource Management (RM)
cell. The count of the cells transmitted includes data cells, OAM
cells, backward RM cells, and the forward RM cell.
A value of 2 is not recommended although it is permitted according
to the ATM Forum standard. When this attribute is set to a value of
2, it is possible that only one forward and one backward RM cell
are repeatedly transmitted, and all data traffic is queued up
indefinitely.

atmIfVpcVpdTmAbrMaxTimeBetweenRmCellsThis attribute specifies the TRM parameter for this connection.
TRM provides an lower bound on the time interval between forward
Resource Management (RM) cells for an ABR source. Since the last
forward RM cell was sent, if at least TRM time has elapsed since
and at least two other cells have been sent, then the next cell to be
transmitted would be a forward RM cell.

atmIfVpcVpdTmAbrCutoffDecreaseFactorThis attribute specifies the Cutoff Decrease Factor (CDF) parameter
for this connection. When the value of this attribute is non-zero,
CDF is computed as the inverse of the value. For example, if the
value is 32, the value of CDF is 1/32. When the value of this
attribute is 0, CDF is also zero.
CDF controls the decrease in the Allowed Cell Rate (ACR)
associated with the CRM parameter, the limit of the number of
forward Resource Management (RM) cells which may be sent in
the absence of received backward RM cells. When this limit is
crossed, the ACR value would be decreased by the amount
(CDF*ACR). The ACR is not allowed to fall below the Minimum
Cell Rate (MCR), in which case the ACR is set to MCR.
The value of CRM is indicated by the forwardRmCellLimit
attribute.

atmIfVpcVpdTmAbrAcrDecreaseTimeFactorThis attribute specifies the Allowed Cell Rate Decrease Time Factor
(ADTF) parameter for this connection.
ADTF is the maximum time interval permitted between sending
forward Resource Management (RM) cells before the Allowed Cell
Rate (ACR) is decreased to initialCellRate. In other words, if the
source does not transit a forward RM cell for the period specified by
adtf, it reduces its ACR to the value of its initialCellRate.

atmIfVpcVpdTmAbrDgcraMaximumDelayThis attribute specifies an upper bound on the delay after which the
rate change induced by a backward Resource Management (RM)
cell departing from this connection point (in the backward

forward direction).
This upper bound may be approximated as the sum of the round trip
fixed and propagation delays and the maximum queuing delays
between the ABR source and this interface.
The value of this attribute is used in policing an ABR connection
using the Dynamic General Cell Rate Algorithm (DGCRA). A
larger value for this attribute implies a more lenient policer. When
there is a reduction in the Allowed Cell Rate (ACR), the policer
waits for a correspondingly longer period of time before it enforces

The value of this attribute is used in policing an ABR connection
using the Dynamic Generic Cell Rate Algorithm (DGCRA). A
larger value for this attribute implies a more lenient policer. When
the delay between two consecutive forward Resource Management

basic Vpts.
A value of sameAsCa means to use the default common or per-VC
transmit queue limit as defined by the CA service category for this
connection.
A value from 5 to 63,488 indicates that a specific transmit queue
limit is requested which differs from the default which is defined
under the CA component for this service category. A specific value

atmIfVpcVpdTmHoldingPriorityThis attribute specifies the holding priority of this connection. In a
situation where the link bandwidth fluctuates, such as over an IMA
link, holding priority is used to determine which connections are
held and which are released. Holding priority 4 connections are the
first to be released. Holding priority 0 connections are the last to be
released. This value provisioned in the Vcd or Vpd may be
overridden by certain applications, for example Vcc Test, which run
over this connection. The default holding priority for a provisioned

atmIfVpcVpdTmAtmServiceCategoryThis attribute specifies the ATM service category for both directions
of the connection.
The value derivedFromBBC may only be used if the SrcPvc
component is provisioned under this Vcc. Otherwise a specific
ATM service category must be specified.
If this attribute is set to derivedFromBBC, the Broadband Bearer
Capability (BBC) and bestEffort attributes are used to determine the
atmServiceCategory of this connection.
If this attribute is set to other than derivedFromBBC, the value of
this attribute is used to override the provisioned BBC Information
Element parameters. In those cases, the BBC attributes are not used.
The constantBitRate service category is intended for real time
applications, that is those requiring tightly constrained delay and
delay variation, as would be appropriate for voice and video
applications. The consistent availability of a fixed quantity of
bandwidth is considered appropriate for CBR service. Cells which
are delayed beyond the value specified by Cell Transfer Delay are
assumed to be of significantly reduced value to the application.
The rtVariableBitRate service category is intended for real time
applications, that is those requiring tightly constrained delay and
delay variation, as would be appropriate for voice and video
applications. Sources are expected to transmit at a rate which varies
with time. Equivalently, the source can be described as 'bursty'.
Cells which are delayed beyond the value specified by CTD are
assumed to be of significantly reduced value to the application. Real
time VBR service may support statistical multiplexing of real time
sources.
The nrtVariableBitRate service category is intended for non-real
time applications which have bursty traffic characteristics and which
can be characterized in terms of a PCR, SCR, and MBS. For those
cells which are transferred within the traffic contract, the application
expects a low cell loss ratio. For all connections, it expects a bound
on the mean cell transfer delay. Non-real time VBR service may
support statistical multiplexing of connections.
The availableBitRate service is an ATM layer service category for
which the limiting ATM layer transfer characteristics provided by
the network may change subsequent to connection establishment.
ABR service has a flow control mechanism which supports several
types of feedback to control the source rate in response to changing
ATM layer transfer characteristics. ABR service is not intended to
support real-time applications.
The unspecifiedBitRate service is intended for non-real time
applications; that is, those not requiring tightly constrained delay
and delay variation. UBR sources are expected to be bursty. UBR
service supports a high degree of statistical multiplexing among
sources. UBR service does not specify traffic related service
guarantees. No numerical commitments are made with respect to
the cell loss ratio experienced by a UBR connection, or as to the
cell transfer delay experienced by cells on the connection.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.114.4.2.2.100.1.42 |
atmIfVpcVpdTmTrafficShapingThis attribute specifies whether this connection uses traffic shaping
when transmitting traffic to the ATM interface.
This attribute is ignored if the atmServiceCategory is
availableBitRate.
When sameAsCa is selected, traffic shaping for the connection is
based on the trafficShaping attribute of the connection's service
category component under the CA. If the service category has
trafficShaping set to enabled or inverseUpc, then traffic shaping is
enabled for the connection. Note that enabling traffic shaping may
have no effect under certain cases. These cases are listed in the
description of the trafficShaping operational attribute, which is
under the Vcc Tm, Vpc Tm, or Vpt Tm components.
When disabled is selected, traffic shaping for this connection is

category component.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.114.4.2.2.100.1.50 |
atmIfVpcVpdTmUnshapedTransmitQueueingThis attribute only applies when this connection is unshaped. This
attribute specifies the transmit queueing method for this connection
if it is unshaped. The two possible methods are per-VC queuing and
common queuing.
On ATM IP FPs, this attribute must be set to sameAsCa.
This attribute is ignored in the following situations:
- if the connection has trafficShaping enabled or inverseUpc, or
- if the atmServiceCategory is availableBitRate, or
- if the atmServiceCategory is constantBitRate and this is a CQC-
based ATM FP.
- for basic Vpts and standard Vpt Vccs
When this attribute is set to sameAsCa, the transmit queueing
method for the connection is based on the
unshapedTransmitQueueing attribute of the connection's service
category component under the CA.
When this attribute is set to common, transmit traffic on this
unshaped connection is destined for the common queue.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.114.4.2.2.100.1.60 |
atmIfVpcVpdTmWeightThis attribute specifies an override for the weight of this unshaped
connection. This attribute is ignored for shaped connections, for
ABR connections, for connections on a CQC-based ATM FP, and
basic Vpts.
When the value is set to sameAsCa, the weight is determined by the
fairnessWeight attribute under the CA service category component
for all but standard Vpt Vccs. For standard Vpt Vccs, the weight is
determined by the Vcc's service category, when the value is set to
sameAsCa.
When this attribute is set to a value from 1 to 4095, that value is
used for the fairness weight of this connection relative to other
connections. For all but standard Vpt Vccs, fairness weight
determines the proportion of transmit cell opportunities which are
allocated to this connection, compared to other connections in the
same service category. For standard Vpt Vccs, fairness weight
determines the proportion of transmit cell opportunities which are
allocated to this connection, compared to other connections
associated with the Vpt.
When the value is set to upToQueueLimit, the fairness weight is
limited only by the txQueueLimit.

atmIfVpcVpdTmForceTaggingThis attribute specifies whether force tagging is enforced for this
connection for cells in the transmit direction.
On CQC-based ATM cards, and for Vpts, this attribute is not
applicable and is ignored.
When the value is set to sameAsCa, the force tagging functionality
is determined by the forceTagging attribute under the CA service
category component.
When the value is set to enabled, force tagging is enabled for cells
in the transmit direction on this connection. When this option is
selected, the CLP bit is set to 1 for all cells in the transmit direction.
Cells which are tagged are counted in the txCellClp attribute.
When the value is set to disabled, force tagging is disabled for cells
in the transmit direction on this connection. When this option is
selected, the CLP bit is unchanged for cells in the transmit
direction.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.114.4.2.2.100.1.62 |
atmIfVpcVpdTmUsageParameterControlThis attribute specifies whether this connection enforces usage
parameter control when receiving traffic from the ATM interface.
When sameAsCa is selected, UPC for the connection is based on
the usageParameterControl attribute of the service category
component under the AtmIf CA. If the service category has UPC
enforced or monitored, then UPC is set to that value for the
connection.
When disabled is selected, UPC for this connection is disabled
regardless of the provisioning of the service category.
When enforced is selected, UPC for this connection is enforced
regardless of the provisioning of the service category.
ATM IP cards provide the ability to monitor UPC violations without
tagging or discarding. When monitored is selected, UPC is actively
checking conformance for the connection and counting the
violations, but is not discarding or tagging cells which do not
conform to the connection traffic contract.
If this is a connection of serviceCategory abr on an ATM IP card,
and the abrConnectionType is sourceDest, virtualSourceDest or
explicitRate, selecting enforced enables dynamic generic cell rate
algorithm (DGCRA) to discard violating cells. Selecting monitored
enables DGCRA to count violating cells.
Note that setting UPC to enforced or monitored may have no effect
under certain cases. These cases are listed in the description of the
usageParameterControl operational attribute, which is under the

atmIfVpcVpdTmBearerClassBbcThis attribute specifies the bearer capability. This attribute is only
used for SPVC and SPVP connections. It is one of the Broadband
Bearer Capability (BBC) attributes. The purpose of the BBC
information element is to indicate a requested broadband
connection-oriented bearer service to be provided by the network.
The value derivedFromServiceCategory specifies that the actual
value which is used for this connection is derived from the value of
the atmServiceCategory. Either, this attribute must be set to
derivedFromServiceCategory, or the atmServiceCategory attribute
must be set to derivedFromBBC, but not both.
Class a service is a connection-oriented, constant bit rate ATM
transport service. Class a service has end to end timing
requirements and may require stringent cell loss, cell delay and cell
delay variation performance.When a is set, the user is requesting
more than an ATM only service. The network may look at the AAL
to provide interworking based upon its contents.
Class c service is a connection-oriented, variable bit rate ATM
transport service. Class c service has no end-to-end timing
requirements. When c is set, the user is requesting more than an
ATM only service. The network interworking function may look at
the AAL and provide service based on it.
Class x service is a connection-oriented ATM transport service
where the AAL, trafficType (vbr or cbr) and timing requirements
are user defined (that is, transparent to the network).When x is set
the user is requesting an ATM only service from the network. In this
case, the network shall not process any higher layer protocol.
Class vp service is used to specify a transparent VP service. When
the value of this attribute is vp, the user is requesting an ATM only
service from the network. In this case, the network shall not process
any higher layer protocol. This service differs from class x service
in that with the class vp service both the VCI field (except or VCI
values 0, 3, 4, and 6 through 15) and Payload Type field are
transported transparently by the network. This attribute value is
only applicable to SPVP connections.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.114.4.2.2.100.1.71 |

The VBR traffic type refers to traffic offered on services such as
packetized audio and video, or data.
The value no indication for traffic type is used if the user has not set
the traffic type; similarly for end-to-end timing.
The value yes for end-to-end timing indicates that end-to-end
timing is required.
The value no for end-to-end timing indicates that end-to-end timing
is not required.
The value derivedFromServiceCategory specifies that the actual

atmIfVpcVpdTmTxPacketWiseDiscardThis attribute specifies whether packet-wise discard functions are to
be enabled or disabled in the transmit data direction for this
connection. Packet-wise discard functions should only be requested
if this connection is transferring AAL5 frame traffic. This attribute
is not applicable for Vpts.
Packet-wise functions increase the 'goodput' of the link. The
transmit packet-wise functions are Early Packet Discard (EPD) and
Partial Packet Discard (PPD).
EPD allows the connection to discard an entire frame once the
transmit queue has reached the EPD threshold. EPD increases the
'goodput' of a link, since discarding an entire frame means that
some queue capacity is guarded for some other frame which is
already partially transmitted. All cells of the frame are discarded
from the Beginning of Message (BOM) cell up to and including the
End of Message (EOM) cell.
PPD allows the connection to discard the remainder of a cell-
forwarded AAL5 frame if one cell of this frame has been discarded.
All cells are discarded up to but not including the EOM cell. The
PPD function increases the 'goodput' of the link, since cells which
are only going to be discarded at the AAL5 reassembly point are
not transmitted.
On CQC-based ATM cards, the packet-wise discard functions are
PPD and EPD. PPD is available at VCC cell-transfer points. PPD is
not applicable at frame-cell conversion points, and is not applicable
for Vpcs. PPD is configured by this attribute. Packet-wise discard
should only be enabled for connections carrying AAL5
segmentation traffic. Setting the value to enabled for any other
traffic type may result in all traffic being discarded. On CQC-based
ATM FPs, EPD is automatically enabled at frame-to-cell conversion
points, independent of the setting of this attribute.
On ATM IP cards, packet-wise discard functions include EPD and
PPD. PPD and EPD apply to individual VCCs and VCCs within
VPCs at all connection points, including tandem VPC connections.
Both PPD and EPD are controlled by this attribute. This attribute
may safely be set to enabled for any connection (Vcc or Vpc) on
ATM IP FPs since they have the ability to automatically detect
AAL5-segmented traffic on a connection, and only enable packet-
wise discards if AAL5-segmented traffic is detected.
When this attribute is set to enabled, packet-wise discard functions
are applied to transmit traffic at this connection point. When this
attribute is set to disabled, packet-wise discard functions are not
applied to transmit traffic at this connection point.
At a SPVC origin on a PNNI interface, a value of enabled specifies
that frame discard is requested in the backward direction. When this
attribute is set to disabled, backward frame discard is not requested
in the SPVC call setup.
The transmit packet-wise discard functions that are active are
visible in the Vcc/Vpc Tm txPacketWiseDiscard operational
attribute.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.114.4.2.2.100.1.76 |
atmIfVpcVpdTmTxWredModeThis attribute specifies the activation of weighted random early
detection (WRED) functionality. WRED is only available on ATM
IP FPs. On CQC-based ATM FPs, this attribute is ignored. If
txPacketWiseDiscard is set to disabled this attribute is ignored. This
attribute is not applicable for Vpts or Vpt Vccs.
WRED is applied in the transmit direction for this connection.
WRED function should be enabled only for connections which are
transferring TCP/IP traffic. WRED acts to prevent synchronization
of multiple TCP/IP sources by randomly discarding a small
percentage of frames when transmit queue congestion reaches the
designated level. W-RED may also be used to differentiate service
on VCC's by preferentially discarding one VCC before another.
Discards start at 0% of cells, when the queue is part-way to the
Early Packet Discard (EPD) threshold, and rise to 100% of cells
discarded at the EPD threshold. WRED discards all the cells in a
frame.
If this attribute is set to enabled, WRED is enabled for all
applications linked to the given Vcc. If it is set to perFlow, each
TCP application has individual control over whether to enable or
disable WRED
If txPacketWiseDiscard is set to disabled, or if this attribute is set to
disabled, WRED functionality is disabled.
If WRED is active, it is visible in the Vcc/Vpc Tm

atmIfVpcVpdTmRxPacketWiseDiscardThis attribute specifies whether packet-wise discard functions are to
be enabled or disabled in the receive data direction for this
connection. Packet-wise discard functions should only be requested
if this connection is transferring AAL5 frame traffic. This attribute
is not applicable for Vpts.
Packet-wise functions increase the 'goodput' of the link. The
receive packet-wise function is Partial Packet Discard (PPD).
PPD allows the connection to discard the remainder of a cell-
forwarded AAL5 frame if one cell of this frame has been discarded,
for example due to UPC. All cells are discarded up to but not
including the EOM cell. The PPD function increases the 'goodput'
of the link, since cells which are only going to be discarded at the
AAL5 reassembly point are not transmitted.
PPD is available at all VCC connection points where UPC may be
activated. PPD is not applicable for Vpcs.
On CQC-based ATM FPs, packet-wise discards should only be
enabled for connections carrying AAL5 segmentation traffic.
Setting the value to enabled for any other traffic type may result in
traffic being discarded.
On ATM IP cards, this attribute may safely be set to enabled for any
connection (Vcc or Vpc) since they have the ability to automatically
detect AAL5-segmented traffic on a connection, and only enables
packet-wise discards if AAL5-segmented traffic is detected.
When this attribute is set to enabled, packet-wise discard functions
are applied to receive traffic at this connection point. When this
attribute is set to disabled, packet-wise discard functions are not
applied to receive traffic at this connection point.
At a SPVC origin on a PNNI interface, a value of enabled specifies
that frame discard is requested in the forward direction. When this
attribute is set to disabled, forward frame discard is not requested in
the SPVC call setup.
The receive packet-wise discard functions that are active are visible
in the Vcc/Vpc Tm rxPacketWiseDiscard operational attribute.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.114.4.2.2.100.1.78 |
atmIfVpcVpdTmAbrConnectionTypeThis attribute specifies the type of ABR behavior which is to be
enforced at this connection. This attribute is only applicable if the
atmServiceCategory attribute is availableBitRate. If the
atmServicecategory attribute is not availableBitRate, this attribute
value is ignored.
The actual ABR functionality which is in effect is visible in the
Vcc/Vpc/Vpt Tm abrConnectionType operational attribute.
For CQC-based ATM cards, the only allowable values are
sameAsCa, nonAbrInterworking or abrSwitch. If abrSwitch is
selected, the CQC implements EFCI marking behavior.
sameAsCa is used to request the default behavior as specified in the
CA Abr component for this Vcc. Otherwise, this attribute overrides
the default behavior.
virtualSourceDest is used to request that this connection point
function as a virtual source/virtual destination. VS/VD functionality
is only supported on ATM IP FPs.
sourceDest requires that this connection point function as a S/D for
RM cells. S/D mode is automatically invoked at this connection
point either if this is a connection end point, or if the next hop
connection point is configured as nonAbrInterworking.
nonAbrInterworking is used to request that this connection point
function as an interworking between ABR and non-ABR service
categories. This means that there are no RM cells on the link side of
this connection, and that the next hop connection point is
performing as an ABR sourceDest.
abrSwitch is used to request ABR switch behavior for this
connection point. The ABR switch behavior is first, to confirm to
virtualSourceDest or nonAbrInterworking setting on the next hop,
and otherwise to implement ABR ER switch behavior. For CQC-
based FPs, ABR switch behavior is implemented as EFCI marking.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.114.4.2.2.100.1.90 |
atmIfVpcVpdTmTxTdpTableThis attribute is a vector of five traffic parameters whose meanings
are defined by the txTrafficDescType attribute.
The values of peak cell rate (PCR), sustained cell rate (SCR),
Minimum Cell Rate (MCR) and requested shaping rate are
expressed in cell/s. Maximum burst size (MBS) is expressed in
cells. CDVT is expressed in microseconds. The values of PCR,
SCR, MCR, MBS and CDVT are used for connection admission
control (CAC). The value of CDVT is only used for connections
where the atmServiceCategory is constantBitRate. For all other
values of atmServiceCategory, CDVT is ignored. The values of
PCR, SCR, MCR and requested shaping rate are used to determine
the actual shaping rate where traffic shaping is enabled.
When txTrafficDescType is 1 or 2, all of the parameters must be set
to zero.
When txTrafficDescType is 3, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic; parameter 4 represents the CDVT; and
parameter 5 represents the requested shaping rate. A non-zero value
in parameter 5 overrides any value in parameter 1. This result is
used as the PCR. Parameter 1 must be non-zero. Parameters 2 and 3
must be zero.
When txTrafficDescType is 4, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic with cell discard; parameter 2
represents the PCR for CLP equal to 0 traffic; parameter 4
represents the CDVT; and parameter 5 represents the requested
shaping rate. A non-zero value in parameter 5 overrides any value in
parameter 1. This result is used as the PCR. Parameter 1 must be
greater than or equal to parameter 2. Parameters 1 and 2 must be
non-zero. Parameter 3 must be zero.
When txTrafficDescType is 5, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic with cell tagging; parameter 2
represents the PCR for CLP equal to 0 traffic; parameter 4
represents the CDVT; and parameter 5 represents the requested
shaping rate. A non-zero value in parameter 5 overrides any value in
parameter 1. This result is used as the PCR. Parameter 1 must be
greater than or equal to parameter 2. Parameters 1 and 2 must be
non-zero. Parameter 3 must be zero.
When txTrafficDescType is 6, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic; parameter 2 represents the SCR for
CLP equal to 0 and 1 traffic; parameter 3 represents the MBS for
CLP equal to 0 and 1 traffic; parameter 4 represents the CDVT; and
parameter 5 represents the requested shaping rate. A non-zero value
in parameter 5 overrides any value in parameter 1. This result is
used as the PCR. Parameters 1, 2 and 3 must be non-zero.
Parameter 1 must be greater than or equal to parameter 2. Parameter
5, must either be zero (unused) or greater than or equal to parameter
2.
When txTrafficDescType is 7, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic; parameter 2 represents the SCR for
CLP equal to 0 with cell discard; parameter 3 represents the MBS
for CLP equal to 0 traffic; parameter 4 represents the CDVT; and
parameter 5 represents the requested shaping rate. A non-zero value
in parameter 5 overrides any value in parameter 1. This result is
used as the PCR. Parameters 1, 2 and 3 must be non-zero.
Parameter 1 must be greater than or equal to parameter 2. Parameter
5, must either be zero (unused) or greater than or equal to parameter
2.
When txTrafficDescType is 8, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic; parameter 2 represents the SCR for
CLP equal to 0 traffic with cell tagging; parameter 3 represents the
MBS for CLP equal to 0 traffic; parameter 4 represents the CDVT;
and parameter 5 represents the requested shaping rate. A non-zero
value in parameter 5 overrides any value in parameter 1. This result
is used as the PCR. Parameters 1, 2 and 3 must be non-zero.
Parameter 1 must be greater than or equal to parameter 2. Parameter
5, must either be zero (unused) or greater than or equal to parameter
2.
When txTrafficDescType is 9, parameter 1 represents the PCR;
parameter 2 represents the CDVT; parameter 3 represents the MCR;
parameter 4 and parameter 5 represent are not used and must be
zero. Parameter 1 must be non-zero and must be greater than or
equal to parameter 3. Parameter 3 may be optionally zero.
Whenever it is valid for PCR to be specified, parameter 5 may also
be used to specify a requested shaping rate. A non-zero value in
parameter 5 overrides the value in parameter 1 and is used as the
peak cell rate in calculations of CAC and shaping rate. When the
atmServiceCategory is availableBitRate (ABR), the shaping rate is
dynamically chosen, based on the ABR flow control mechanism, as
a value between the MCR and the PCR or the requested shaping
rate if applicable.
For txTrafficDescType 3, 4 and 5, the transmit traffic is shaped at
the next available shaping rate less than the PCR.
For txTrafficDescType 6, 7 and 8 if linear traffic shaping is selected,
the transmit traffic is shaped at the highest available rate which is
between PCR and SCR. However, if there is no available shaping
rate between PCR and SCR, traffic is shaped at the next rate above
the PCR.
For txTrafficDescType 6, 7 and 8 if inverse-UPC traffic shaping is
selected, the transmit traffic is shaped at a variable rate which
conforms to the PCR, SCR and MBS of the connection traffic
descriptor. Inverse-UPC traffic shaping is available only on ATM IP
cards. SEQUENCE OF AtmIfVpcVpdTmTxTdpEntry .1.3.6.1.4.1.3764.1.1.30.114.4.2.2.456 |

are defined by the rxTrafficDescType attribute. The values of peak
cell rate (PCR), sustained cell rate (SCR) and Minimum Cell Rate
(MCR) are expressed in cell/s. Maximum burst size (MBS) is
expressed in cells. The value of CDVT is expressed in

When rxTrafficDescType is 3, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic. Parameter 1 must be non-zero.
Parameters 2 and 3 must be set to zero (unused).
When rxTrafficDescType is 4, parameter 1 represents the PCR

Parameter 4 is not used and must be zero. Parameter 1,must be non-
zero and must be greater than or equal to parameter 3. Parameter 3
may optionally be zero.
When rxTrafficDescType is any value from 3 through 8, parameter
4 represents the CDVT.
If the value of CDVT either in parameter 2 or in parameter 4 is zero,
the CDVT is taken from the CA defaults for the particular
atmServiceCategory of this connection.
On a CQC-based ATM card, when rxTrafficDescriptorType is 3
through 8, there are certain extreme combinations of
rxTrafficDescParm which are outside the capabilities of the UPC
hardware. The check prov command detects such cases and
generates an error message. If this happens, adjust the parameters
until they fall within the supported limits.
To calculate the limits, use the following formulae:
I1 = 1 000 000 000 / PCR
L1 = CDVT * 1000
I2 = 1,000,000,000 / SCR
L2 = CDVT + (MBS - 1) * (I2 - I1)
I1 and I2 must be less than or equal to 335,523,840. I1 + L1 must
be less than or equal to 1,342,156,800. I2 + L2 must be less than or
equal to 1,342,156,800. Note that I2 and L2 only apply when the
rxTrafficDescriptorType is 6 through 8.
If the values of I1, L1, I2 or L2 are closer to the limits described
above, a further restriction applies. Specifically, if either:
I1 > 41,940,480 or
I2 > 41,940,480 or
I1 + L1 > 167,769,600 or
I2 + L2 > 167,769,600
then both I1 and I2 must be greater than 20,480.
Parameter 5 of the rxTrafficDescParm is always unused.
If the rxTrafficDescType is sameAsTx, the values provisioned in
this attribute are ignored. The traffic parameters for the receive
direction are taken from the txTrafficDescParm. SEQUENCE OF AtmIfVpcVpdTmRxTdpEntry .1.3.6.1.4.1.3764.1.1.30.114.4.2.2.457 |

component is provisioned under this Vcc.Otherwise a specific ATM
service category must be specified.
If this attribute is set to derivedFromBBC, the Broadband Bearer
Capability (BBC) and bestEffort attributes are used to determine the
atmServiceCategory of this connection.
If this attribute is set to other than derivedFromBBC, the value of
this attribute is used to override the provisioned BBC Information
Element parameters. In those cases, the BBC attributes are not used.
The constantBitRate service category is intended for real time
applications, that is those requiring tightly constrained delay and
delay variation, as would be appropriate for voice and video
applications. The consistent availability of a fixed quantity of
bandwidth is considered appropriate for CBR service. Cells which
are delayed beyond the value specified by Cell Transfer Delay are
assumed to be of significantly reduce value to the application.
The rtVariableBitRate service category is intended for real time
applications, that is those requiring tightly constrained delay and
delay variation, as would be appropriate for voice and video
applications. Sources are expected to transmit at a rate which varies
with time. Equivalently, the source can be described as 'bursty'.
Cells which are delayed beyond the value specified by CTD are
assumed to be of significantly reduced value to the application. Real
time VBR service may support statistical multiplexing of real time
sources.
The nrtVariableBitRate service category is intended for non-real
time applications which have bursty traffic characteristics and which
can be characterized in terms of a PCR, SCR, and MBS. For those
cells which are transferred within the traffic contract, the application
expects a low cell loss ratio. For all connections, it expects a bound
on the mean cell transfer delay. Non-real time VBR service may
support statistical multiplexing of connections.
The unspecifiedBitRate service is intended for non-real time
applications; that is, those not requiring tightly constrained delay
and delay variation. UBR sources are expected to be bursty. UBR
service supports a high degree of statistical multiplexing among
sources. UBR service does not specify traffic related service
guarantees. No numerical commitments are made with respect to
the cell loss ratio experienced by a UBR connection, or as to the
cell transfer delay experienced by cells on the connection.rwobsolete Enumeration .1.3.6.1.4.1.3764.1.1.30.114.4.2.110.1.42 |
atmIfVpcVpdTrafficShapingThis attribute is migrated to the AtmTmProv group.
This attribute specifies whether this connection uses traffic shaping
when transmitting traffic to the ATM interface.
When sameAsInterface is selected, traffic shaping for the
connection is based on the trafficShaping attribute of the
connection's parent AtmIf componentif the ATM interface has
traffic shaping enabled, then traffic shaping is enabled for the
connection. Note that enabling traffic shaping may have no effect
under certain cases. These cases are listed in the description of the
trafficShaping operational attribute, which is under the Vcc and Vpc
components.
When disabled is selected, traffic shaping for this connection is

This attribute specifies whether this connection enforces usage
parameter control when receiving traffic from the ATM interface.
When sameAsInterface is selected, UPC for the connection is
based on the usageParameterControl attribute of the connection's
parent AtmIf componentif the ATM interface has UPC enabled,
then UPC is enabled for the connection. Note that enabling UPC
may have no effect under certain cases. These cases are listed in the

atmIfVpcVpdBearerClassBbcThis attribute is migrated to the AtmTmProv group.
This attribute specifies the bearer capability. This attribute is only
used for SPVC and SPVP connections. It is one of the Broadband
Bearer Capability (BBC) attributes. The purpose of the BBC
information element is to indicate a requested broadband
connection-oriented bearer service to be provided by the network.
The value derivedFromServiceCategory specifies that the actual
value which is used for this connection is derived from the value of
the atmServiceCategory. Either, this attribute must be set to
derivedFromServiceCategory, or the atmServiceCategory attribute
must be set to derivedFromBBC, but not both.
Class a service is a connection-oriented, constant bit rate ATM
transport service. Class a service has end to end timing
requirements and may require stringent cell loss, cell delay and cell
delay variation performance.When a is set, the user is requesting
more than an ATM only service. The network may look at the AAL
to provide interworking based upon its contents.
Class c service is a connection-oriented, variable bit rate ATM
transport service. Class c service has no end-to-end timing
requirements. When c is set, the user is requesting more than an
ATM only service. The network interworking function may look at
the AAL and provide service based on it.
Class x service is a connection-oriented ATM transport service
where the AAL, trafficType (vbr or cbr) and timing requirements
are user defined (that is, transparent to the network).When x is set
the user is requesting an ATM only service from the network.
Class vp service is used to specify a transparent VP service. When
the value of this attribute is vp, the user is requesting an ATM only
service from the network. In this case, the network shall not process
any higher layer protocol. This service differs from class x service
in that with the class vp service both the VCI field (except or VCI
values 0, 3, 4, and 6 through 15) and Payload Type field are
transported transparently by the network. This attribute value is
only applicable to SPVP connections.rwobsolete Enumeration .1.3.6.1.4.1.3764.1.1.30.114.4.2.110.1.71 |
atmIfVpcVpdTransferCapabilityBbcThis attribute is migrated to the AtmTmProv group.
This attribute specifies the transfer capability for this connection.
Uni 3.0/3.1 traffic type and end-to-end timing parameters are
mapped into this parameter as follows:
<transferCapability: TrafficType, Timing>
0: NoIndication, NoIndication
1: NoIndication, yes
2: NoIndication, no
5: CBR, yes
8: VBR, NoIndication
9: VBR, yes
10: VBR, no
NotApplicable specifies that the user does not want to specify the
transfer capability.
The CBR traffic type refers to traffic offered on services such as a
constant bit rate video service or a circuit emulation.
The VBR traffic type refers to traffic offered on services such as
packetized audio and video, or data.
The value no indication for traffic type is used if the user has not set
the traffic type; similarly for end-to-end timing.
The value yes for end-to-end timing indicates that end-to-end
timing is required.
The value no for end-to-end timing indicates that end-to-end timing
is not required.
The value derivedFromServiceCategory specifies that the actual
value which is used for this connection is derived from the value of
the atmServiceCategory. Either, this attribute must be set to
derivedFromServiceCategory, or the atmServiceCategory attribute
must be set to derivedFromBBC, but not both.rwobsolete Enumeration .1.3.6.1.4.1.3764.1.1.30.114.4.2.110.1.72 |

This attribute specifies the value for the clipping susceptibility
parameter in the BBC Information Element. This attribute is only
used for SPVC connections. It is one of the Broadband Bearer

This attribute specifies the value of the best effort parameter in the
ATM Traffic Descriptor Information Element. This attribute is only
used for Soft PVC connections. It is one of the Broadband Bearer

The value indicated implies that the quality of service for this
connection is not guaranteed.
The value notIndicated implies that the quality of service for this
connection is guaranteed.
The value derivedFromServiceCategory specifies that the actual
value which is used for this connection is derived from the value of
the atmServiceCategory. Either, this attribute must be set to

must be set to derivedFromBBC, but not both.rwobsolete Enumeration .1.3.6.1.4.1.3764.1.1.30.114.4.2.110.1.75 |
atmIfVpcVpdFwdFrameDiscardThis attribute specifies the activation of frame discard functionality
in the forward data direction, at relay points, for this connection. It
applies to each hop of the connection. Frame discard functions
should not be requested if this connection is not transferring frame
(AAL5) traffic. Setting the value to indicated for any other traffic
type results in all traffic being discarded.
If this connection point is a permanent (provisioned) VCC mid-
point, this attribute specifies whether the Partial Packet
Discard (PPD) function is to be enabled or disabled in the transmit
direction at this connecting point. The PPD function allows the
connecting point to discard the remainder of a cell-forwarded AAL5
frame if one cell of this frame has been discarded. The PPD
function increases the 'goodput' of the link, since cells which are
only going to be discarded by the AAL5 reassembly are not
transmitted.
At a permanent VCC connecting point which is not a connection
endpoint, when this attribute is set to indicated, the PPD function is
applied to transmit traffic at this connecting point. It should not be
indicated for connections whose end points are not performing
AAL5 segmentation and reassembly. When this attribute is set to
notIndicated, the PPD feature is not applied to transmit traffic at
this connecting point.
At a SPVC origin on a PNNI interface, a value of indicated
specifies that frame discard is requested in the forward direction.
The frame discard function for SPVCs consists of PPD at the SPVC
origin and at all intermediate connecting points. When this attribute
is set to notIndicated, forward frame discard is not requested in the
SPVC call setup. Thus PPD is not enabled at the SPVC origin nor at
any intermediate connecting point.
At all points along a VPC, this setting is ignored.
At a permanent VCC connection endpoint, this value is ignored. If
AAL5 segmentation and reassembly has been requested, PPD and
Early Packet Discard (EPD) are automatically enabled.

atmIfVpcVpdBwdFrameDiscardThis attribute specifies the activation of frame discard functionality
in the backward data direction, at relay points, for this connection.
It applies to each hop of the connection. Frame discard functions
should not be requested if this connection is not transferring frame
(AAL5) traffic. Setting the value to indicated for any other traffic
type results in all traffic being discarded.
If this connection point is a permanent (provisioned) VCC mid-
point, this attribute specifies whether the Partial Packet Discard
(PPD) function is to be enabled or disabled in the receive direction
at this connecting point. The PPD function allows the connecting
point to discard the remainder of a cell-forwarded AAL5 frame if
one cell of this frame has been discarded. The PPD function
increases the 'goodput' of the link, since cells which are only going
to be discarded by the AAL5 reassembly are not received.
At a permanent VCC connecting point which is not a connection
endpoint, when this attribute is set to indicated, the PPD function is
applied to receive traffic at this connecting point. It should not be
indicated for connections whose end points are not performing
AAL5 segmentation and reassembly. When this attribute is set to
notIndicated, the PPD feature is not applied to receive traffic at this
connecting point.
At a SPVC origin on a PNNI interface, a value of indicated
specifies that frame discard is requested in the backward direction.
The frame discard function for SPVCs consists of PPD at the SPVC
origin and at all intermediate connecting points. When this attribute
is set to notIndicated, backwards frame discard is not requested in
the SPVC call setup. Thus PPD is not enabled at the SPVC origin
nor at any intermediate connecting point.
At all points along a VPC, this setting is ignored.
At a permanent VCC connection endpoint, this value is ignored. If
AAL5 segmentation and reassembly has been requested, PPD and
Early Packet Discard (EPD) are automatically enabled.

atmIfVpcVpdTxTdpTableThis attribute is migrated to the AtmTmProv group.
This attribute is a vector of five traffic parameters whose meanings
are defined by the txTrafficDescType attribute. The values of peak
cell rate (PCR), sustained cell rate (SCR) and requested shaping rate
are expressed in cell/s. Maximum burst size (MBS) is expressed in
cells. CDVT is expressed in microseconds. The values of PCR,
SCR, MBS and CDVT are used for connection admission control
(CAC). The value of CDVT is only used for connections where the
atmServiceCategory is constantBitRate. For all other values of
atmServiceCategory, CDVT is ignored. The values of PCR, SCR
and requested shaping rate are used to determine the actual shaping
rate where traffic shaping is enabled.
When txTrafficDescType is 1 or 2, all of the parameters must be set
to zero.
When txTrafficDescType is 3, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic; parameter 4 represents the CDVT; and
parameter 5 represents the requested shaping rate. A non-zero value
in parameter 5 overrides any value in parameter 1. This result is
used as the PCR. Parameter 1 must be non-zero. Parameters 2 and 3
must be zero.
When txTrafficDescType is 4, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic with cell discard; parameter 2
represents the PCR for CLP equal to 0 traffic; parameter 4
represents the CDVT; and parameter 5 represents the requested
shaping rate. A non-zero value in parameter 5 overrides any value in
parameter 1. This result is used as the PCR. Parameter 1 must be
greater than or equal to parameter 2. Parameters 1 and 2 must be
non-zero. Parameter 3 must be zero.
When txTrafficDescType is 5, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic with cell tagging; parameter 2
represents the PCR for CLP equal to 0 traffic; parameter 4
represents the CDVT; and parameter 5 represents the requested
shaping rate. A non-zero value in parameter 5 overrides any value in
parameter 1. This result is used as the PCR. Parameter 1 must be
greater than or equal to parameter 2. Parameters 1 and 2 must be
non-zero. Parameter 3 must be zero.
When txTrafficDescType is 6, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic; parameter 2 represents the SCR for
CLP equal to 0 and 1 traffic; parameter 3 represents the MBS for
CLP equal to 0 and 1 traffic; parameter 4 represents the CDVT; and
parameter 5 represents the requested shaping rate. A non-zero value
in parameter 5 overrides any value in parameter 1. This result is
used as the PCR. Parameters 1, 2 and 3 must be non-zero.
Parameter 1 must be greater than or equal to parameter 2. Parameter
5, must either be zero (unused) or greater than or equal to parameter
2.
When txTrafficDescType is 7, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic; parameter 2 represents the SCR for
CLP equal to 0 with cell discard; parameter 3 represents the MBS
for CLP equal to 0 traffic; parameter 4 represents the CDVT; and
parameter 5 represents the requested shaping rate. A non-zero value
in parameter 5 overrides any value in parameter 1. This result is
used as the PCR. Parameters 1, 2 and 3 must be non-zero.
Parameter 1 must be greater than or equal to parameter 2. Parameter
5, must either be zero (unused) or greater than or equal to parameter
2.
When txTrafficDescType is 8, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic; parameter 2 represents the SCR for
CLP equal to 0 traffic with cell tagging; parameter 3 represents the
MBS for CLP equal to 0 traffic; parameter 4 represents the CDVT;
and parameter 5 represents the requested shaping rate. A non-zero
value in parameter 5 overrides any value in parameter 1. This result
is used as the PCR. Parameters 1, 2 and 3 must be non-zero.
Parameter 1 must be greater than or equal to parameter 2. Parameter
5, must either be zero (unused) or greater than or equal to parameter
2.
Whenever it is valid for PCR to be specified, parameter 5 may also
be used to specify a requested shaping rate. A non-zero value in
parameter 5 overrides the value in parameter 1 and is used as the
peak cell rate in calculations of CAC and shaping rate.
For txTrafficDescType 3, 4 and 5, the transmit traffic is shaped at
the next rate less than the PCR.
For txTrafficDescType 6, 7 and 8, the transmit traffic is shaped at
the highest available rate which is between PCR and SCR.
However, if there is no available shaping rate between PCR and
SCR, traffic is shaped at the next rate above the PCR.obsolete SEQUENCE OF AtmIfVpcVpdTxTdpEntry .1.3.6.1.4.1.3764.1.1.30.114.4.2.297 |

zero. Parameter 1 must be greater than or equal to parameter 2.
When rxTrafficDescType is any value from 3 through 8, parameter
4 represents the CDVT. If this value is zero, the CDVT is taken
from the ConnectionAdministrator defaults for the particular
atmServiceCategory of this connection.
When rxTrafficDescriptorType is 3 through 8, there are certain
extreme combinations of rxTrafficDescParm which are outside the
capabilities of the UPC hardware. The check prov command detects
such cases and generates an error message. If this happens, adjust
the parameters until they fall within the supported limits.
To calculate the limits, use the following formulae:
I1 = 1 000 000 000 / PCR
L1 = CDVT * 1000
I2 = 1 000 000 000 / SCR
L2 = CDVT + (MBS - 1) * (I2 - I1)
I1 and I2 must be less than or equal to 335 523 840. I1 + L1 must
be less than or equal to 1 342 156 800. I2 + L2 must be less than or
equal to 1 342 156 800. Note that I2 and L2 only apply when the
rxTrafficDescriptorType is 6 through 8.
If the values of I1, L1, I2 or L2 are closer to the limits described
above, a further restriction applies. Specifically, if either:
I1 > 41 940 480 or
I2 > 41 940 480 or
I1 + L1 > 167 769 600 or
I2 + L2 > 167 769 600
then both I1 and I2 must be greater than 20 480.
Parameter 5 of the rxTrafficDescParm is always unused.
If the rxTrafficDescType is sameAsTx, the values in this attribute
are taken from the txTrafficDescParm.obsolete SEQUENCE OF AtmIfVpcVpdRxTdpEntry .1.3.6.1.4.1.3764.1.1.30.114.4.2.298 |

This attribute indicates the Initial Cell Rate (ICR) parameter for this
connection. ICR is the rate at which a source should send initially
and after an idle period.
For nailed-up connections, this attribute is determined by the
provisioned value of the initialCellRate attribute. For signalled
connections, it is indicated in the ABR Setup Parameters
Information Element.
The ICR for a connection is a value between the MCR and the PCR.

atmIfVpcTmAbrRateDecreaseFactorThis attribute is applicable and is displayed only for connections for
which the operational Tm abrConnectionType is displayed as
sourceDest or virtualSourceDest.
This attribute indicates the Rate Decrease Factor (RDF) for this
connection. The RDF value is computed by using the operational
value of this attribute, n, as 2 to the inverse power n. For example, if
the value of this attribute is 8, RDF is 2E-8 = 1/256.
RDF controls the amount by which the cell transmission rate may
decrease upon receipt of a backward Resource Management (RM)
cell. For example, if a backward RM cell is received with the
Congestion Indication (CI) field set to 1, the Allowed Cell Rate
(ACR) value would be reduced by the amount (RDF*ACR). The
ACR is not allowed to fall below the Minimum Cell Rate (MCR), in
which case the ACR is set to MCR.

atmIfVpcTmAbrRateIncreaseFactorThis attribute is applicable and is displayed only for connections for
which the operational Tm abrConnectionType is displayed as
sourceDest or virtualSourceDest.
This attribute indicates the Rate Increase Factor (RIF) for this
connection. The RIF value is computed by using the operational
value of this attribute, n, as 2 to the inverse power n. For example, if
the value of this attribute is 6, RIF is 2E-6 = 1/64.
RIF controls the amount by which the cell transmission rate may
increase upon receipt of a backward Resource Management (RM)
cell. For example, if a backward RM cell is received with the
Congestion Indication (CI) and the No Increase (NI) fields both set
to 0, the Allowed Cell Rate (ACR) value would be increased by the
amount (RIF*ACR). The ACR is not allowed to exceed the Peak
Cell Rate (PCR), in which case the ACR is set to PCR.

atmIfVpcTmAbrMaxCellPerRmCellThis attribute is applicable and is displayed only for connections for
which the operational Tm abrConnectionType is displayed as
sourceDest or virtualSourceDest.
This attribute indicates the maximum number of cells an ABR
source may transmit for each forward Resource Management (RM)
cell. The count of the cells transmitted includes data cells, OAM
cells, backward RM cells, and the forward RM cell.
For nailed-up connections, this attribute is determined by the
provisioned value of the maxCellsPerRmCell attribute. For
signalled connections, it is indicated in the ABR Additional

atmIfVpcTmAbrMaxTimeBetweenRmCellThis attribute is applicable and is displayed only for connections for
which the operational Tm abrConnectionType is displayed as
sourceDest or virtualSourceDest.
This attribute indicates the TRM parameter for this connection.
TRM provides an upper bound on the time interval between forward
Resource Management (RM) cells for an ABR source. Since the last
forward RM cell was sent, if at least TRM time has elapsed since
and at least 2 other cells have been sent, the next cell to be
transmitted would be a forward RM cell.
For nailed-up connections, this attribute is determined by the
provisioned value of the maxTimeBetweenRmCell attribute. For
signalled connections, it is indicated in the ABR Additional
Parameters Information Element.ro Unsigned32 (781 | 1563 | 3125 | 6250 | 12500 | 25000 | 50000 | 100000) .1.3.6.1.4.1.3764.1.1.30.114.4.9.2.110.1.16 |
atmIfVpcTmAbrCutoffDecreaseFactorThis attribute is applicable and is displayed only for connections for
which the operational Tm abrConnectionType is displayed as
sourceDest or virtualSourceDest.
This attribute indicates the Cutoff Decrease Factor (CDF) parameter
for this connection. When the value of this attribute is non-zero,
CDF is computed as the inverse of the value. For example, if the
value is 32, the value of CDF is 1/32. When the value of this
attribute is 0, CDF is also zero.
CDF controls the decrease in the Allowed Cell Rate (ACR)
associated with the forwardRmCellLimit attribute, the limit of the
number of forward Resource Management (RM) cells which may
be sent in the absence of received backward RM cells. When this
limit is crossed, the ACR value would be decreased by the amount
(CDF*ACR). The ACR is not allowed to fall below the Minimum
Cell Rate (MCR), in which case the ACR is set to MCR.
For nailed-up connections, this attribute is determined by the
provisioned value of the cutoffDecreaseFactor attribute. For
signalled connections, it is indicated in the ABR Additional

atmIfVpcTmAbrAcrDecreaseTimeFactorThis attribute is applicable and is displayed only for connections for
which the operational Tm abrConnectionType is displayed as
sourceDest or virtualSourceDest.
This attribute indicates the Allowed Cell Rate Decrease Time Factor
(ADTF) parameter for this connection.
ADTF is the time interval permitted between sending forward
Resource Management (RM) cells before the Allowed Cell Rate
(ACR) is decreased to initialCellRate. In other words, if the source
does not transit a forward RM cell for the period specified by adtf, it
reduces its ACR to the value of its initialCellRate.

This attribute indicates the CRM parameter for this connection.
CRM is the limit of the number of forward Resource Management
(RM) cells which may be sent in the absence of received backward
RM cells. When this limit is crossed, the Allowed Cell Rate (ACR)
value would be decreased by the amount (CDF*ACR), where CDF
is determined by the cutoffDecreaseFactor. The ACR is not allowed
to fall below the Minimum Cell Rate (MCR), in which case the
ACR is set to MCR.
The value of CRM is obtained as transientBufferExposure divided
by maxCellsPerRmCell.ro Unsigned32 (1 | 3 | 7 | 15 | 31 | 63 | 127 | 255 | 511 | 1023 | 2047 | 4095) .1.3.6.1.4.1.3764.1.1.30.114.4.9.2.110.1.19 |

atmIfVpcTmAtmServiceCategoryThis attribute indicates the ATM service category used for traffic in
both directions of the connection. This attribute does not apply to
Virtual Link VPTs and will always be displayed as
constantBitRate.
The constantBitRate service category is intended for real time
applications, that is, those requiring tightly constrained delay and
delay variation, as would be appropriate for voice and video
applications. The consistent availability of a fixed quantity of
bandwidth is considered appropriate for CBR service. Cells which
are delayed beyond the value specified by Cell Transfer Delay are
assumed to have significantly reduced value for the application.
The rtVariableBitRate service category is intended for real time
applications; that is those requiring tightly constrained delay and
delay variation, as would be appropriate for voice and video
applications. Sources are expected to transmit at a rate which varies
with time. Equivalently, the source can be described as 'bursty'.
Cells which are delayed beyond the value specified by Cell Transfer
Delay are assumed to be of significantly reduced value to the
application. Real time VBR service may support statistical
multiplexing of real time sources.
The nrtVariableBitRate service category is intended for non-real
time applications which have bursty traffic characteristics and which
can be characterized in terms of a PCR, SCR, and MBS. For those
cells which are transferred within the traffic contract, the application
expects a low cell loss ratio. For all connections, it expects a bound
on the mean cell transfer delay. Non-real time VBR service may
support statistical multiplexing of connections.
The availableBitRate service is an ATM layer service category for
which the limiting ATM layer transfer characteristics provided by
the network may change subsequent to connection establishment.
ABR service has a flow control mechanism which supports several
types of feedback to control the source rate in response to changing
ATM layer transfer characteristics. ABR service is not intended to
support real-time applications.
The unspecifiedBitRate service is intended for non-real time
applications, that is those not requiring tightly constrained delay
and delay variation. UBR sources are expected to be bursty. UBR
service supports a high degree of statistical multiplexing among
sources. UBR service does not specify traffic related service
guarantees. No numerical commitments are made with respect to
the cell loss ratio experienced by a UBR connection, or as to the
cell transfer delay experienced by cells on the connection.ro Enumeration .1.3.6.1.4.1.3764.1.1.30.114.4.9.100.1.62 |
atmIfVpcTmTrafficShapingThis attribute indicates the traffic shaping state of the connection.
A value of notApplicable indicates that traffic shaping is not
applicable or not supported for this connection. This is the case:
- when the txTrafficDescType is 1 or 2.
- for standard Vpt Vccs and basic Vpts.
- for CQC-based ATM cards, when the atmServiceCategory is
constantBitRate.
In these cases, the value of notApplicable is set regardless of
whether traffic shaping is enabled or disabled in the provisioning
data.
A value of disabled indicates that traffic shaping is applicable and
supported for the type of connection but has been turned off in the
provisioning data.
A value of linear or inverseUpc indicates that traffic shaping is
applicable and supported for the type of connection and has been
turned on in the provisioning data. This is the only case that
indicates that traffic shaping is performed on the connection. In this
case, the actual shaping rate is reflected in the txTrafficDescParm
attribute, parameter number 4. A value of linear indicates that
traffic is being shaped at the constant rate indicated in
txTrafficDescParm 4.
A value of inverseUpc is possible only on ATM IP cards. This value
indicates that the shaper strictly conforms to the requirements of a
dual leaky bucket UPC enforcer. This value is indicated if traffic
shaping is enabled, and the txTrafficDescType for this connection is
6, 7 or 8.
Traffic shaping for connections with atmServiceCategory as
availableBitRate (txTrafficDescType 9) depends upon the
abrConnectionType attribute. If abrConnectionType is sourceDest
or virtualSourceDest, the value of this attribute is dynamic. If
abrConnectionType is erSwitch or efciSwitch, this attribute is

Class c service is a connection-oriented, variable bit rate ATM
transport service. Class c service has no end-to-end timing
requirements.When c is displayed, the user is requesting more than
an ATM only service. The network interworking function may look
at the AAL and provide service based on it.
Class x service is a connection-oriented ATM transport service
where the AAL, trafficType (cbr or vbr), and timing requirements
are user defined (that is, transparent to the network). When the
value of this attribute is x, the user is requesting an ATM only
service from the network. In this case, the network shall not process
any higher layer protocol.
Class vp service is used to indicate a transparent VP service when
the user is requesting an ATM only service from the network. In this
case, the network does not process any higher layer protocol. This
service differs from class x service in that with the class vp service
both the VCI field (except for VCI values 0, 3, 4, and 6 through 15)
and Payload Type field are transported transparently by the network.

ATM IP cards provide the ability to monitor UPC violations without
tagging or discarding. A value of monitored indicates that UPC is
actively checking conformance for the connection and counting the
violations, but is not discarding or tagging cells which do not
conform to the connection traffic contract. The traffic descriptor
parameters used for UPC conformance are reflected in the
rxTrafficDescParms of the connection. The counts of UPC
violations are visible in the Vcc, Vpc, or Vpt
rxUpcViolationsOnEnforcer1 or rxUpcViolationsOnEnforcer2
attributes. The value of monitored appears only on ATM IP cards.

atmIfVpcTmBandwidthElasticThis attribute is only of importance for connections which are
carried on a link with a variable bandwidth. For example, the
bandwidth may be reduced in the event that one or more physical
links in the IMA group fail, such that the originally requested
bandwidth cannot be maintained. This attribute shows whether the
application (for example, Trunk) running on this connection can
continue to operate if the bandwidth is reduced. If the bandwidth is
reduced, the amount by which it is reduced is displayed in the
bandwidthReduction attribute.
A value of yes, indicates that this connection is elastic, and the
bandwidth may be reduced but the connection is not released.
A value of no indicates that the bandwidth for this connection is not
reduced in the event of link bandwidth reduction. However, this
connection may be released based on its holdingPriority.
Bandwidth elasticity has no effect for connections which have an
equivalent cell rate (ECR) of zero.
This attribute is not applicable for Vpts and Vpt Vccs.ro Enumeration .1.3.6.1.4.1.3764.1.1.30.114.4.9.100.1.90 |
atmIfVpcTmBandwidthReductionThis attribute shows the amount by which the bandwidth has been
reduced for this connection. This value is non-zero only for
connections which have bandwidthElastic displayed as yes, and
which are also operating in a reduced bandwidth mode. This is
typically the case for selected connections running over an IMA
link. This attribute takes a value from 0 (no reduction) up to the
ECR. For all connections which are running at their full allocated
bandwidth, bwReduction has the value 0. Connections which have
been reduced in allocated bandwidth have a positive number for this
attribute. The bwReduction may be subtracted from the ECR (which
is displayed as txTrafficDescParm 5) to determine the actual
bandwidth allocated to this connection.ro Unsigned32 .1.3.6.1.4.1.3764.1.1.30.114.4.9.100.1.100 |
atmIfVpcTmAbrConnectionTypeThis attribute indicates the type of ABR behavior which is in effect
at this connection. This attribute is only applicable if the
atmServiceCategory attribute is availableBitRate. If the
atmServiceCategory attribute is not availableBitRate, or if the
connection is not active, this attribute value is displayed as
notApplicable.
For CQC-based ATM cards, the only possible values are
notApplicable, efciSwitch or nonAbrInterworking. In EFCI
marking mode, the Explicit Forward Congestion Indication (EFCI)
field in the data cell headers is used to indicate transmit queue
congestion.
For ATM IP cards, if the connectionPointType is displayed as
connectionEndPoint, this attribute has the value sourceDest. In this
mode, the ABR Source and Destination behavior is in effect at this
connection. This attribute is also sourceDest in the case where the
next hop connection is specified as nonAbrInterworking. The next
hop connection is the Vcc or Vpc identified by the nextHop attribute
of the Nrp or Rp component.
If the connectionPointType is not connectionEndPoint, the value of
this attribute depends upon the abrConnectionType provisioning
and the card type to which the traffic is forwarded on the backplane.
The default abrConnectionType is provisioned at the CA Abr
abrConnectionType attribute, and may be overridden for a
provisioned connection in the Vcd Tm abrConnectionType or Vpd
Tm abrConnectionType attribute. If the CA Abr abrConnectionType
attribute is virtualSourceDest at either one of the two connection
points, and if both the connection points are defined on ATM IP
cards, virtual source and destination behavior is applied to the
connection. In this instance, the attribute displays the value
virtualSourceDest.
This attribute has the value erSwitch if ABR explicit rate
functionality is in effect at this connection. In this mode, the switch
may modify the Explicit Rate (ER) field of backward Resource
Management (RM) cells to indicate the status of congestion at this
connection point.
This attribute has the value nonAbrInterworking in the case where
this connection point is functioning as an SPVC origin for an ABR
connection where the link side of this connection is configured as a
non-ABR ATM service category. This means that there are no RM
cells on the link side of this connection, and that the next hop
connection point is performing as an ABR sourceDest.ro Enumeration .1.3.6.1.4.1.3764.1.1.30.114.4.9.100.1.110 |
atmIfVpcTmTxTdpTableThis attribute is a vector of five transmit traffic parameters whose
mapping is defined by the txTrafficDescType attribute.
The values of peak cell rate (PCR), sustained cell rate (SCR),
Minimum Cell Rate (MCR), actual cell rate (ACR), explicit rate
(ER), equivalent cell rate (ECR), and actual shaping rate are
expressed in cell/s. Maximum burst size (MBS) is expressed in
cells. CDVT is expressed in microseconds.
When txTrafficDescType is 1 or 2, parameters 1 through 5 are
unused.
In this description, PCR is the greater of either the PCR or the
requested shaping rate (parameter 1 or parameter 5) specified in the
txTrafficDescParm attribute under the Vcd Tm or Vpd Tm
component.
When txTrafficDescType is 3, parameter 1 represents the PCR for
CLP equal to 0 or 1 traffic; parameters 2 and 3 are unused.
When txTrafficDescType is 4, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic; parameter 2 represents the PCR for
CLP equal to 0 traffic with cell discard.
When txTrafficDescType is 5, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic; parameter 2 represents the PCR for
CLP equal to 0 traffic with cell tagging.
When txTrafficDescType is 6, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic; parameter 2 represents the SCR for
CLP equal to 0 and 1 traffic; parameter 3 represents the MBS for

CLP equal to 0 traffic with cell discard; parameter 3 represents the
MBS for CLP equal to 0 traffic.
When txTrafficDescType is 8, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic; parameter 2 represents the SCR for
CLP equal to 0 traffic with cell tagging; parameter 3 represents the
MBS for CLP equal to 0 traffic.
When txTrafficDescType is 3, 4, 5, 6, 7, or 8, parameter 4 reflects
the actual shaping rate in cell/s for this connection. For CQC-based
ATM cards, the set of available shaping rates is based on the
number of interfaces doing shaping (attribute
perVcQueueInterfaces), and the shapingScalingFactor attribute of
the Arc Cqc Override component. A rate of zero (0) indicates that
shaping is not performed, or that the interface is down.
When txTrafficDescType is 9, parameter 1 represents the PCR;
parameter 2 represents the Cell Delay Variation Toleration (CDVT);
parameter 3 represents the Minimum Cell Rate (MCR); the meaning
of parameter 4 depends upon the value of the abrConnectionType
attribute. if abrConnectionType is sourceDest or
virtualSourceDest, parameter 4 represents the Allowed Cell Rate
(ACR); If abrConnectionType is erSwitch, parameter 4 represents
the Explicit Rate (ER); and if abrConnectionType is efciSwitch,
parameter 4 reflects the actual shaping rate in cell/s for this
connection.
When txTrafficDescType is 3, 4, 5, 6, 7, 8, or 9, parameter 5 reflects
the equivalent cell rate in cell/s for this connection as determined by
the Connection Admission Control (CAC) algorithm. The
equivalent cell rate is useful in determining the admission
characteristics of this connection. SEQUENCE OF AtmIfVpcTmTxTdpEntry .1.3.6.1.4.1.3764.1.1.30.114.4.9.451 |

atmIfVpcRxOamCellCongestionStateThis attribute contains the current state of the receive side OAM cell
congestion for this connection. Its value reflects whether the rate of
received OAM cells for this connection is below a specified
threshold. The connection maintains a count of the number of OAM
cells which are terminated per second. Once that count exceeds the
specified threshold, extraction of all OAM cells for this connection
is disabled for a period of one minute. This is a congestion
management mechanism to prevent the processor from being
overloaded with handling OAM cells for a particular connection.
This mechanism ensures that tasks, such as trunks obtain enough
processor cycles to remain in service, and are not adversely affected
by excessive rate of OAM cells on a particular connection.
The value is good when the rate of received OAM cells is less than
the allowed threshold.
The value is bad when the arrival rate has exceeded the allowed
threshold. It remains bad for one minute, before returning to good
again. During this timeout, extraction of all OAM cells is disabled
for this connection. As a result, other loopback failure conditions
may occur.
The value is unknown when the application has not yet begun to
use this connection. An example is the Test component before a test
has been started.
Each type of OAM cell is counted separately. The threshold for AIS
cells is three cells per second. If more than three AIS cells are
received within a one second interval, this attribute is set to bad.
The threshold for RDI cells and each loopback type is also three,
but the threshold for trace cells is 250 per second.
The state of this attribute has no direct effect on the value of the

atmIfVpcAtmServiceCategoryThis attribute is HISTORICAL. Please refer to the attribute of the
same name in the group AtmTmOper.
This attribute indicates the ATM service category used for traffic in
both directions of the connection.
The constantBitRate service category is intended for real time
applications, that is, those requiring tightly constrained delay and
delay variation, as would be appropriate for voice and video
applications. The consistent availability of a fixed quantity of
bandwidth is considered appropriate for CBR service. Cells which
are delayed beyond the value specified by Cell Transfer Delay are
assumed to have significantly reduced value of the application.
The rtVariableBitRate service category is intended for real time
applications; that is those requiring tightly constrained delay and
delay variation, as would be appropriate for voice and video
applications. Sources are expected to transmit at a rate which varies
with time. Equivalently, the source can be described as 'bursty'.
Cells which are delayed beyond the value specified by Cell Transfer
Delay are assumed to be of significantly reduced value to the
application. Real time VBR service may support statistical
multiplexing of real time sources.
The nrtVariableBitRate service category is intended for non-real
time applications which have bursty traffic characteristics and which
can be characterized in terms of a PCR, SCR, and MBS. For those
cells which are transferred within the traffic contract, the application
expects a low cell loss ratio. For all connections, it expects a bound
on the mean cell transfer delay. Non-real time VBR service may
support statistical multiplexing of connections.
The unspecifiedBitRate service is intended for non-real time
applications, that is those not requiring tightly constrained delay
and delay variation. UBR sources are expected to be bursty. UBR
service supports a high degree of statistical multiplexing among
sources. UBR service does not specify traffic related service
guarantees. No numerical commitments are made with respect to
the cell loss ratio experienced by a UBR connection, or as to the
cell transfer delay experienced by cells on the connection.roobsolete Enumeration .1.3.6.1.4.1.3764.1.1.30.114.4.130.1.62 |
atmIfVpcTrafficShapingThis attribute is HISTORICAL. Please refer to the attribute of the

when the atmServiceCategory is constantBitRate, or when the
txTrafficDescType is 1 or 2. In these cases, the value of
notApplicable is set regardless of whether traffic shaping is enabled
or disabled in the provisioning data.
A value of disabled indicates that traffic shaping is applicable and
supported for the type of connection but has been turned off in the
provisioning data.
A value of enabled indicates that traffic shaping is applicable and
supported for the type of connection and has been turned on in the
provisioning data. This is the only case that indicates that traffic
shaping is performed on the connection. In this case, the actual

atmIfVpcBearerClassBbcThis attribute is HISTORICAL. Please refer to the attribute of the
same name in the group AtmTmOper.
This attribute indicates the bearer capability for this connection.
Class a service is a connection-oriented, constant bit rate ATM
transport service. Class a service has end to end timing
requirements and may require stringent cell loss, cell delay and cell
delay variation performance.When a is displayed, the user is
requesting more than an ATM only service. The network may look
at the AAL to provide interworking based upon its contents.
Class c service is a connection-oriented, variable bit rate ATM
transport service. Class c service has no end-to-end timing
requirements.When c is displayed, the user is requesting more than
an ATM only service. The network interworking function may look
at the AAL and provide service based on it.
Class x service is a connection-oriented ATM transport service
where the AAL, trafficType (cbr or vbr) and timing requirements
are user defined (that is, transparent to the network). When the
value of this attribute is x, the user is requesting an ATM only
service from the network. In this case, the network shall not process
any higher layer protocol.
Class vp service is used to indicate a transparent VP service when
the user is requesting an ATM only service from the network. In this
case, the network does not process any higher layer protocol. This
service differs from class x service in that with the class vp service
both the VCI field (except for VCI values 0, 3, 4, and 6 through 15)
and Payload Type field are transported transparently by the network.

atmIfVpcBandwidthElasticThis attribute is HISTORICAL. Please refer to the attribute of the
same name in the group AtmTmOper.
This attribute is only of importance for connections which are
carried on a link with a variable bandwidth. For example, the
bandwidth may be reduced in the event that one or more physical
links in the IMA group fail, such that the originally requested
bandwidth cannot be maintained. This attribute shows whether the
application (for example, Trunk) running on this connection can
continue to operate if the bandwidth is reduced. If the bandwidth is
reduced, the amount by which it is reduced is displayed in the
bandwidthReduction attribute.
A value of yes, indicates that this connection is elastic, and the
bandwidth may be reduced but the connection is not released.
A value of no indicates that the bandwidth for this connection is not
reduced in the event of link bandwidth reduction. However, this
connection may be released based on its holdingPriority.
Bandwidth elasticity has no effect for ubr atmServiceCategory or
txTrafficDescriptorType 1 or 2 connections.roobsolete Enumeration .1.3.6.1.4.1.3764.1.1.30.114.4.130.1.90 |
atmIfVpcBandwidthReductionThis attribute is HISTORICAL. Please refer to the attribute of the
same name in the group AtmTmOper.
This attribute shows the amount by which the bandwidth has been
reduced for this connection. This value is non-zero only for
connections which have bandwidthElastic displayed as yes, and
which are also operating in a reduced bandwidth mode. This is
typically be the case for selected connections running over an IMA
link. This attribute takes a value from 0 (no reduction) up to the
ECR. All connections which are running at their full allocated
bandwidth, bwReduction have the value 0. Connections which have
been reduced in allocated bandwidth have a positive number for this
attribute. The bwReduction may be subtracted from the ECR (which
is displayed as txTrafficDescParm 5) to determine the actual
bandwidth allocated to this connection.roobsolete INTEGER .1.3.6.1.4.1.3764.1.1.30.114.4.130.1.100 |

atmIfVpcTxQThreshTableThis attribute is HISTORICAL. Please refer to the attribute of the
same name in the group AtmTmOper.
This attribute indicates the queue limit and the discard thresholds
for the transmit queue of this connection.
The first element indicates the queue limit. Depending upon the
atmServiceCategory of the connection, the provisioned value of the
transmit queue limit is derived from the txQueueLimit attribute
under one of the subcomponents of the AtmIf CA component. If the
connection has traffic shaping disabled, then this attribute relates to
the common queue. If traffic shaping is enabled, then this attribute
relates to the per-VC queue.
The second element is the threshold that marks the transition from
congestion state 1 to congestion state 0. This is the threshold at
which traffic with discard priority (DP) = 1 is discarded. This
threshold is set approximately at 90 percent of the first parameter,
the operational queue limit.
The third element is the threshold that marks the transition from
congestion state 2 to congestion state 1. This is the threshold at
which traffic with DP = 2 is discarded. This threshold is set
approximately at 75 percent of the first parameter, the operational
queue limit.
The fourth element is the threshold that marks the transition from
congestion state 3 to congestion state 2. This is the threshold at
which traffic with DP = 3 is discarded. This threshold is set
approximately at 35 percent of the first parameter, the operational
queue limit.obsolete SEQUENCE OF AtmIfVpcTxQThreshEntry .1.3.6.1.4.1.3764.1.1.30.114.4.352 |

atmIfVccVcdTmAbrInitialCellRateThis attribute specifies the Initial Cell Rate (ICR) parameter for this
connection. ICR is the rate at which a source should send initially
and after an idle period.
When this attribute is set to sameAsCa, the initial cell rate is
determined by the AtmIf CA Abr/0 icr attribute. When the value of
this attribute is set to useMcr, ICR is set to the same value as the
Minimum Cell Rate (MCR) for the connection.
When the value of this attribute is set to usePcr, ICR is set to the
same value as the Peak Cell Rate (PCR) for the connection.
If this attribute is specified less than the MCR of the connection,
then the MCR is used as the ICR. If this attribute is specified more
than PCR of the connection, then PCR is used as the ICR.
This attribute is ignored under all conditions where the operational
attribute abrConnectionType indicates erSwitch or efciSwitch.

atmIfVccVcdTmAbrTransientBufferExposureThis attribute specifies the Transient Buffer Exposure (TBE) for this
connection. TBE is the negotiated number of cells that the network
would like to limit the source to send during start-up periods, before
the first Resource Management (RM) cell returns.
TBE divided by fixedRoundTripTime determines an upper bound
for the operational value of initialCellRate, the rate at which a
source should send initially and after an idle period.
TBE divided by maxCellsPerRmCell specifies the operational value
of forwardRmCellLimit, the limit of the number of forward
Resource Management (RM) cells which may be sent in the
absence of received backward RM cells.
This attribute is ignored under all conditions where the operational

atmIfVccVcdTmAbrFixedRoundTripTimeThis attribute specifies the Fixed Round-Trip Time (FRTT)
parameter for this connection. FRTT is the sum of the fixed and
propagation delays from the source to a destination and back.
The value of transientBufferExposure divided by the value of FRTT
(in seconds) determines an upper bound for the operational value of
initialCellRate, the rate at which a source should send initially and
after an idle period.
This attribute is ignored under all conditions where the operational
attribute abrConnectionType indicates erSwitch or efciSwitch.rw Unsigned32 .1.3.6.1.4.1.3764.1.1.30.114.5.2.2.2.110.1.12 |
atmIfVccVcdTmAbrRateDecreaseFactorThis attribute specifies the Rate Decrease Factor (RDF) for this
connection. The RDF value is computed by using the provisioned
value of this attribute, n, as 2 to the inverse power n. For example, if
the value of this attribute is 8, RDF is 2E-8 = 1/256.
RDF controls the amount by which the cell transmission rate may
decrease upon receipt of a backward Resource Management (RM)
cell. For example, if a backward RM cell is received with the
Congestion Indication (CI) field set to 1, the Allowed Cell Rate
(ACR) value would be reduced by the amount (RDF*ACR). The
ACR is not allowed to fall below the Minimum Cell Rate (MCR), in
which case the ACR is set to MCR.
This attribute is ignored under all conditions where the operational
attribute abrConnectionType has the value erSwitch.

atmIfVccVcdTmAbrRateIncreaseFactorThis attribute specifies the Rate Increase Factor (RIF) for this
connection. The RIF value is computed by using the provisioned
value of this attribute, n, as 2 to the inverse power n. For example, if
the value of this attribute is 6, RIF is 2E-6 = 1/64.
RIF controls the amount by which the cell transmission rate may
increase upon receipt of a backward Resource Management (RM)
cell. For example, if a backward RM cell is received with the
Congestion Indication (CI) and the No Increase (NI) fields both set
to 0, the Allowed Cell Rate (ACR) value would be increased by the
amount (RIF*ACR). The ACR is not allowed to exceed the Peak
Cell Rate (PCR), in which case the ACR is set to PCR.

atmIfVccVcdTmAbrMaxCellPerRmCellThis attribute specifies the maximum number of cells an ABR
source may transmit for each forward Resource Management (RM)
cell. The count of the cells transmitted includes data cells, OAM
cells, backward RM cells, and the forward RM cell.
A value of 2 is not recommended although it is permitted according
to the ATM Forum standard. When this attribute is set to a value of
2, it is possible that only one forward and one backward RM cell
are repeatedly transmitted, and all data traffic is queued up
indefinitely.

atmIfVccVcdTmAbrMaxTimeBetweenRmCellsThis attribute specifies the TRM parameter for this connection.
TRM provides an lower bound on the time interval between forward
Resource Management (RM) cells for an ABR source. Since the last
forward RM cell was sent, if at least TRM time has elapsed since
and at least two other cells have been sent, then the next cell to be
transmitted would be a forward RM cell.
This attribute is ignored under all conditions where the operational
attribute abrConnectionType has the value erSwitch.

atmIfVccVcdTmAbrCutoffDecreaseFactorThis attribute specifies the Cutoff Decrease Factor (CDF) parameter
for this connection. When the value of this attribute is non-zero,
CDF is computed as the inverse of the value. For example, if the
value is 32, the value of CDF is 1/32. When the value of this
attribute is 0, CDF is also zero.
CDF controls the decrease in the Allowed Cell Rate (ACR)
associated with the CRM parameter, the limit of the number of
forward Resource Management (RM) cells which may be sent in
the absence of received backward RM cells. When this limit is
crossed, the ACR value would be decreased by the amount
(CDF*ACR). The ACR is not allowed to fall below the Minimum
Cell Rate (MCR), in which case the ACR is set to MCR.
The value of CRM is indicated by the forwardRmCellLimit
attribute.

atmIfVccVcdTmAbrAcrDecreaseTimeFactorThis attribute specifies the Allowed Cell Rate Decrease Time Factor
(ADTF) parameter for this connection.
ADTF is the maximum time interval permitted between sending
forward Resource Management (RM) cells before the Allowed Cell
Rate (ACR) is decreased to initialCellRate. In other words, if the
source does not transit a forward RM cell for the period specified by
adtf, it reduces its ACR to the value of its initialCellRate.

atmIfVccVcdTmAbrDgcraMaximumDelayThis attribute specifies an upper bound on the delay after which the
rate change induced by a backward Resource Management (RM)
cell departing from this connection point (in the backward
direction) is expected to be observed at this connection point (in the
forward direction).
This upper bound may be approximated as the sum of the round trip
fixed and propagation delays and the maximum queuing delays
between the ABR source and this interface.
The value of this attribute is used in policing an ABR connection
using the Dynamic General Cell Rate Algorithm (DGCRA). A
larger value for this attribute implies a more lenient policer. When
there is a reduction in the Allowed Cell Rate (ACR), the policer
waits for a correspondingly longer period of time before it enforces

atmIfVccVcdTmTxQueueLimitThis attribute specifies an override to the default transmit queue
limit for this connection. A value other than sameAsCa may be
specified only for ATM IP cards. This attribute is not applicable for
basic Vpts.
A value of sameAsCa means to use the default common or per-VC
transmit queue limit as defined by the CA service category for this
connection.
A value from 5 to 63,488 indicates that a specific transmit queue
limit is requested which differs from the default which is defined
under the CA component for this service category. A specific value
is ignored for connections where common queuing is specified for
the service category.

atmIfVccVcdTmHoldingPriorityThis attribute specifies the holding priority of this connection. In a
situation where the link bandwidth fluctuates, such as over an IMA
link, holding priority is used to determine which connections are
held and which are released. Holding priority 4 connections are the
first to be released. Holding priority 0 connections are the last to be
released. This value provisioned in the Vcd or Vpd may be
overridden by certain applications, for example Vcc Test, which run
over this connection. The default holding priority for a provisioned
connection is higher then default holding priorities for dynamic
(SVC) connections.

atmIfVccVcdTmRxTrafficDescTypeThis attribute specifies the type of traffic management which is
applied to the receive direction of this connection as defined in the
ATM Forum. The rxTrafficDescType determines the number and

atmIfVccVcdTmAtmServiceCategoryThis attribute specifies the ATM service category for both directions
of the connection.
The value derivedFromBBC may only be used if the SrcPvc
component is provisioned under this Vcc. Otherwise a specific
ATM service category must be specified.
If this attribute is set to derivedFromBBC, the Broadband Bearer
Capability (BBC) and bestEffort attributes are used to determine the
atmServiceCategory of this connection.
If this attribute is set to other than derivedFromBBC, the value of
this attribute is used to override the provisioned BBC Information
Element parameters. In those cases, the BBC attributes are not used.
The constantBitRate service category is intended for real time
applications, that is those requiring tightly constrained delay and
delay variation, as would be appropriate for voice and video
applications. The consistent availability of a fixed quantity of
bandwidth is considered appropriate for CBR service. Cells which
are delayed beyond the value specified by Cell Transfer Delay are
assumed to be of significantly reduced value to the application.
The rtVariableBitRate service category is intended for real time
applications, that is those requiring tightly constrained delay and
delay variation, as would be appropriate for voice and video
applications. Sources are expected to transmit at a rate which varies
with time. Equivalently, the source can be described as 'bursty'.
Cells which are delayed beyond the value specified by CTD are
assumed to be of significantly reduced value to the application. Real
time VBR service may support statistical multiplexing of real time
sources.
The nrtVariableBitRate service category is intended for non-real
time applications which have bursty traffic characteristics and which
can be characterized in terms of a PCR, SCR, and MBS. For those
cells which are transferred within the traffic contract, the application
expects a low cell loss ratio. For all connections, it expects a bound
on the mean cell transfer delay. Non-real time VBR service may
support statistical multiplexing of connections.
The availableBitRate service is an ATM layer service category for
which the limiting ATM layer transfer characteristics provided by
the network may change subsequent to connection establishment.
ABR service has a flow control mechanism which supports several
types of feedback to control the source rate in response to changing
ATM layer transfer characteristics. ABR service is not intended to
support real-time applications.
The unspecifiedBitRate service is intended for non-real time
applications; that is, those not requiring tightly constrained delay
and delay variation. UBR sources are expected to be bursty. UBR
service supports a high degree of statistical multiplexing among
sources. UBR service does not specify traffic related service
guarantees. No numerical commitments are made with respect to
the cell loss ratio experienced by a UBR connection, or as to the
cell transfer delay experienced by cells on the connection.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.114.5.2.2.100.1.42 |
atmIfVccVcdTmTrafficShapingThis attribute specifies whether this connection uses traffic shaping
when transmitting traffic to the ATM interface.
This attribute is ignored if the atmServiceCategory is
availableBitRate.
When sameAsCa is selected, traffic shaping for the connection is
based on the trafficShaping attribute of the connection's service
category component under the CA. If the service category has
trafficShaping set to enabled or inverseUpc, then traffic shaping is
enabled for the connection. Note that enabling traffic shaping may
have no effect under certain cases. These cases are listed in the
description of the trafficShaping operational attribute, which is
under the Vcc Tm, Vpc Tm, or Vpt Tm components.
When disabled is selected, traffic shaping for this connection is
disabled regardless of the provisioning of the connection's service
category component.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.114.5.2.2.100.1.50 |
atmIfVccVcdTmUnshapedTransmitQueueingThis attribute only applies when this connection is unshaped. This
attribute specifies the transmit queueing method for this connection
if it is unshaped. The two possible methods are per-VC queuing and
common queuing.
On ATM IP FPs, this attribute must be set to sameAsCa.
This attribute is ignored in the following situations:
- if the connection has trafficShaping enabled or inverseUpc, or
- if the atmServiceCategory is availableBitRate, or
- if the atmServiceCategory is constantBitRate and this is a CQC-
based ATM FP.
- for basic Vpts and standard Vpt Vccs
When this attribute is set to sameAsCa, the transmit queueing
method for the connection is based on the
unshapedTransmitQueueing attribute of the connection's service
category component under the CA.
When this attribute is set to common, transmit traffic on this
unshaped connection is destined for the common queue.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.114.5.2.2.100.1.60 |
atmIfVccVcdTmWeightThis attribute specifies an override for the weight of this unshaped
connection. This attribute is ignored for shaped connections, for
ABR connections, for connections on a CQC-based ATM FP, and
basic Vpts.
When the value is set to sameAsCa, the weight is determined by the
fairnessWeight attribute under the CA service category component
for all but standard Vpt Vccs. For standard Vpt Vccs, the weight is
determined by the Vcc's service category, when the value is set to
sameAsCa.
When this attribute is set to a value from 1 to 4095, that value is
used for the fairness weight of this connection relative to other
connections. For all but standard Vpt Vccs, fairness weight
determines the proportion of transmit cell opportunities which are
allocated to this connection, compared to other connections in the
same service category. For standard Vpt Vccs, fairness weight
determines the proportion of transmit cell opportunities which are
allocated to this connection, compared to other connections
associated with the Vpt.
When the value is set to upToQueueLimit, the fairness weight is
limited only by the txQueueLimit.

atmIfVccVcdTmForceTaggingThis attribute specifies whether force tagging is enforced for this
connection for cells in the transmit direction.
On CQC-based ATM cards, and for Vpts, this attribute is not
applicable and is ignored.
When the value is set to sameAsCa, the force tagging functionality
is determined by the forceTagging attribute under the CA service
category component.
When the value is set to enabled, force tagging is enabled for cells
in the transmit direction on this connection. When this option is
selected, the CLP bit is set to 1 for all cells in the transmit direction.
Cells which are tagged are counted in the txCellClp attribute.
When the value is set to disabled, force tagging is disabled for cells
in the transmit direction on this connection. When this option is
selected, the CLP bit is unchanged for cells in the transmit
direction.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.114.5.2.2.100.1.62 |
atmIfVccVcdTmUsageParameterControlThis attribute specifies whether this connection enforces usage
parameter control when receiving traffic from the ATM interface.
When sameAsCa is selected, UPC for the connection is based on
the usageParameterControl attribute of the service category
component under the AtmIf CA. If the service category has UPC
enforced or monitored, then UPC is set to that value for the
connection.
When disabled is selected, UPC for this connection is disabled
regardless of the provisioning of the service category.
When enforced is selected, UPC for this connection is enforced
regardless of the provisioning of the service category.
ATM IP cards provide the ability to monitor UPC violations without
tagging or discarding. When monitored is selected, UPC is actively
checking conformance for the connection and counting the
violations, but is not discarding or tagging cells which do not
conform to the connection traffic contract.
If this is a connection of serviceCategory abr on an ATM IP card,
and the abrConnectionType is sourceDest, virtualSourceDest or
explicitRate, selecting enforced enables dynamic generic cell rate
algorithm (DGCRA) to discard violating cells. Selecting monitored
enables DGCRA to count violating cells.
Note that setting UPC to enforced or monitored may have no effect
under certain cases. These cases are listed in the description of the
usageParameterControl operational attribute, which is under the
Vcc, Vpc, and Vpt components.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.114.5.2.2.100.1.70 |
atmIfVccVcdTmBearerClassBbcThis attribute specifies the bearer capability. This attribute is only
used for SPVC and SPVP connections. It is one of the Broadband
Bearer Capability (BBC) attributes. The purpose of the BBC
information element is to indicate a requested broadband
connection-oriented bearer service to be provided by the network.
The value derivedFromServiceCategory specifies that the actual
value which is used for this connection is derived from the value of
the atmServiceCategory. Either, this attribute must be set to
derivedFromServiceCategory, or the atmServiceCategory attribute
must be set to derivedFromBBC, but not both.
Class a service is a connection-oriented, constant bit rate ATM
transport service. Class a service has end to end timing
requirements and may require stringent cell loss, cell delay and cell
delay variation performance.When a is set, the user is requesting
more than an ATM only service. The network may look at the AAL
to provide interworking based upon its contents.
Class c service is a connection-oriented, variable bit rate ATM
transport service. Class c service has no end-to-end timing
requirements. When c is set, the user is requesting more than an
ATM only service. The network interworking function may look at
the AAL and provide service based on it.
Class x service is a connection-oriented ATM transport service
where the AAL, trafficType (vbr or cbr) and timing requirements
are user defined (that is, transparent to the network).When x is set
the user is requesting an ATM only service from the network. In this
case, the network shall not process any higher layer protocol.
Class vp service is used to specify a transparent VP service. When
the value of this attribute is vp, the user is requesting an ATM only
service from the network. In this case, the network shall not process
any higher layer protocol. This service differs from class x service
in that with the class vp service both the VCI field (except or VCI
values 0, 3, 4, and 6 through 15) and Payload Type field are
transported transparently by the network. This attribute value is
only applicable to SPVP connections.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.114.5.2.2.100.1.71 |

1: NoIndication, yes
2: NoIndication, no
5: CBR, yes
8: VBR, NoIndication
9: VBR, yes
10: VBR, no
notApplicable specifies that the user does not want to specify the
transfer capability.
The CBR traffic type refers to traffic offered on services such as a
constant bit rate video service or a circuit emulation.
The VBR traffic type refers to traffic offered on services such as
packetized audio and video, or data.
The value no indication for traffic type is used if the user has not set
the traffic type; similarly for end-to-end timing.
The value yes for end-to-end timing indicates that end-to-end
timing is required.
The value no for end-to-end timing indicates that end-to-end timing
is not required.
The value derivedFromServiceCategory specifies that the actual

WRED starts as soon as the queue is 25% of the way to the EPD
threshold. When the value is set to 50%, WRED starts later, after
the queue is 50% of the way to the EPD threshold. When the value
is set to 75%, WRED starts only when the queue is 75% of the way
to the EPD threshold. The EPD threshold is 85% of the transmit

must be set to derivedFromBBC, but not both.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.114.5.2.2.100.1.75 |
atmIfVccVcdTmTxPacketWiseDiscardThis attribute specifies whether packet-wise discard functions are to
be enabled or disabled in the transmit data direction for this
connection. Packet-wise discard functions should only be requested
if this connection is transferring AAL5 frame traffic. This attribute
is not applicable for Vpts.
Packet-wise functions increase the 'goodput' of the link. The
transmit packet-wise functions are Early Packet Discard (EPD) and
Partial Packet Discard (PPD).
EPD allows the connection to discard an entire frame once the
transmit queue has reached the EPD threshold. EPD increases the
'goodput' of a link, since discarding an entire frame means that
some queue capacity is guarded for some other frame which is
already partially transmitted. All cells of the frame are discarded
from the Beginning of Message (BOM) cell up to and including the
End of Message (EOM) cell.
PPD allows the connection to discard the remainder of a cell-
forwarded AAL5 frame if one cell of this frame has been discarded.
All cells are discarded up to but not including the EOM cell. The
PPD function increases the 'goodput' of the link, since cells which
are only going to be discarded at the AAL5 reassembly point are
not transmitted.
On CQC-based ATM cards, the packet-wise discard functions are
PPD and EPD. PPD is available at VCC cell-transfer points. PPD is
not applicable at frame-cell conversion points, and is not applicable
for Vpcs. PPD is configured by this attribute. Packet-wise discard
should only be enabled for connections carrying AAL5
segmentation traffic. Setting the value to enabled for any other
traffic type may result in all traffic being discarded. On CQC-based
ATM FPs, EPD is automatically enabled at frame-to-cell conversion
points, independent of the setting of this attribute.
On ATM IP cards, packet-wise discard functions include EPD and
PPD. PPD and EPD apply to individual VCCs and VCCs within
VPCs at all connection points, including tandem VPC connections.
Both PPD and EPD are controlled by this attribute. This attribute
may safely be set to enabled for any connection (Vcc or Vpc) on
ATM IP FPs since they have the ability to automatically detect
AAL5-segmented traffic on a connection, and only enable packet-
wise discards if AAL5-segmented traffic is detected.
When this attribute is set to enabled, packet-wise discard functions
are applied to transmit traffic at this connection point. When this
attribute is set to disabled, packet-wise discard functions are not
applied to transmit traffic at this connection point.
At a SPVC origin on a PNNI interface, a value of enabled specifies
that frame discard is requested in the backward direction. When this
attribute is set to disabled, backward frame discard is not requested
in the SPVC call setup.
The transmit packet-wise discard functions that are active are
visible in the Vcc/Vpc Tm txPacketWiseDiscard operational
attribute.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.114.5.2.2.100.1.76 |
atmIfVccVcdTmTxWredModeThis attribute specifies the activation of weighted random early
detection (WRED) functionality. WRED is only available on ATM
IP FPs. On CQC-based ATM FPs, this attribute is ignored. If
txPacketWiseDiscard is set to disabled this attribute is ignored. This
attribute is not applicable for Vpts or Vpt Vccs.
WRED is applied in the transmit direction for this connection.
WRED function should be enabled only for connections which are
transferring TCP/IP traffic. WRED acts to prevent synchronization
of multiple TCP/IP sources by randomly discarding a small
percentage of frames when transmit queue congestion reaches the
designated level. W-RED may also be used to differentiate service
on VCC's by preferentially discarding one VCC before another.
Discards start at 0% of cells, when the queue is part-way to the
Early Packet Discard (EPD) threshold, and rise to 100% of cells
discarded at the EPD threshold. WRED discards all the cells in a
frame.
If this attribute is set to enabled, WRED is enabled for all
applications linked to the given Vcc. If it is set to perFlow, each
TCP application has individual control over whether to enable or
disable WRED
If txPacketWiseDiscard is set to disabled, or if this attribute is set to
disabled, WRED functionality is disabled.
If WRED is active, it is visible in the Vcc/Vpc Tm
txPacketWiseDiscard operational attribute.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.114.5.2.2.100.1.77 |
atmIfVccVcdTmRxPacketWiseDiscardThis attribute specifies whether packet-wise discard functions are to
be enabled or disabled in the receive data direction for this
connection. Packet-wise discard functions should only be requested
if this connection is transferring AAL5 frame traffic. This attribute
is not applicable for Vpts.
Packet-wise functions increase the 'goodput' of the link. The
receive packet-wise function is Partial Packet Discard (PPD).
PPD allows the connection to discard the remainder of a cell-
forwarded AAL5 frame if one cell of this frame has been discarded,
for example due to UPC. All cells are discarded up to but not
including the EOM cell. The PPD function increases the 'goodput'
of the link, since cells which are only going to be discarded at the
AAL5 reassembly point are not transmitted.
PPD is available at all VCC connection points where UPC may be
activated. PPD is not applicable for Vpcs.
On CQC-based ATM FPs, packet-wise discards should only be
enabled for connections carrying AAL5 segmentation traffic.
Setting the value to enabled for any other traffic type may result in
traffic being discarded.
On ATM IP cards, this attribute may safely be set to enabled for any
connection (Vcc or Vpc) since they have the ability to automatically
detect AAL5-segmented traffic on a connection, and only enables
packet-wise discards if AAL5-segmented traffic is detected.
When this attribute is set to enabled, packet-wise discard functions
are applied to receive traffic at this connection point. When this
attribute is set to disabled, packet-wise discard functions are not
applied to receive traffic at this connection point.
At a SPVC origin on a PNNI interface, a value of enabled specifies
that frame discard is requested in the forward direction. When this
attribute is set to disabled, forward frame discard is not requested in
the SPVC call setup.
The receive packet-wise discard functions that are active are visible
in the Vcc/Vpc Tm rxPacketWiseDiscard operational attribute.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.114.5.2.2.100.1.78 |
atmIfVccVcdTmAbrConnectionTypeThis attribute specifies the type of ABR behavior which is to be
enforced at this connection. This attribute is only applicable if the
atmServiceCategory attribute is availableBitRate. If the
atmServicecategory attribute is not availableBitRate, this attribute
value is ignored.
The actual ABR functionality which is in effect is visible in the
Vcc/Vpc/Vpt Tm abrConnectionType operational attribute.
For CQC-based ATM cards, the only allowable values are
sameAsCa, nonAbrInterworking or abrSwitch. If abrSwitch is
selected, the CQC implements EFCI marking behavior.
sameAsCa is used to request the default behavior as specified in the
CA Abr component for this Vcc. Otherwise, this attribute overrides
the default behavior.
virtualSourceDest is used to request that this connection point
function as a virtual source/virtual destination. VS/VD functionality
is only supported on ATM IP FPs.
sourceDest requires that this connection point function as a S/D for
RM cells. S/D mode is automatically invoked at this connection
point either if this is a connection end point, or if the next hop
connection point is configured as nonAbrInterworking.
nonAbrInterworking is used to request that this connection point
function as an interworking between ABR and non-ABR service
categories. This means that there are no RM cells on the link side of
this connection, and that the next hop connection point is
performing as an ABR sourceDest.
abrSwitch is used to request ABR switch behavior for this
connection point. The ABR switch behavior is first, to confirm to
virtualSourceDest or nonAbrInterworking setting on the next hop,
and otherwise to implement ABR ER switch behavior. For CQC-
based FPs, ABR switch behavior is implemented as EFCI marking.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.114.5.2.2.100.1.90 |
atmIfVccVcdTmTxTdpTableThis attribute is a vector of five traffic parameters whose meanings
are defined by the txTrafficDescType attribute.
The values of peak cell rate (PCR), sustained cell rate (SCR),
Minimum Cell Rate (MCR) and requested shaping rate are
expressed in cell/s. Maximum burst size (MBS) is expressed in
cells. CDVT is expressed in microseconds. The values of PCR,
SCR, MCR, MBS and CDVT are used for connection admission
control (CAC). The value of CDVT is only used for connections
where the atmServiceCategory is constantBitRate. For all other
values of atmServiceCategory, CDVT is ignored. The values of
PCR, SCR, MCR and requested shaping rate are used to determine
the actual shaping rate where traffic shaping is enabled.
When txTrafficDescType is 1 or 2, all of the parameters must be set
to zero.
When txTrafficDescType is 3, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic; parameter 4 represents the CDVT; and
parameter 5 represents the requested shaping rate. A non-zero value
in parameter 5 overrides any value in parameter 1. This result is
used as the PCR. Parameter 1 must be non-zero. Parameters 2 and 3
must be zero.
When txTrafficDescType is 4, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic with cell discard; parameter 2
represents the PCR for CLP equal to 0 traffic; parameter 4

shaping rate. A non-zero value in parameter 5 overrides any value in
parameter 1. This result is used as the PCR. Parameter 1 must be
greater than or equal to parameter 2. Parameters 1 and 2 must be
non-zero. Parameter 3 must be zero.
When txTrafficDescType is 5, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic with cell tagging; parameter 2
represents the PCR for CLP equal to 0 traffic; parameter 4
represents the CDVT; and parameter 5 represents the requested
shaping rate. A non-zero value in parameter 5 overrides any value in
parameter 1. This result is used as the PCR. Parameter 1 must be
greater than or equal to parameter 2. Parameters 1 and 2 must be
non-zero. Parameter 3 must be zero.
When txTrafficDescType is 6, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic; parameter 2 represents the SCR for
CLP equal to 0 and 1 traffic; parameter 3 represents the MBS for
CLP equal to 0 and 1 traffic; parameter 4 represents the CDVT; and
parameter 5 represents the requested shaping rate. A non-zero value
in parameter 5 overrides any value in parameter 1. This result is
used as the PCR. Parameters 1, 2 and 3 must be non-zero.
Parameter 1 must be greater than or equal to parameter 2. Parameter
5, must either be zero (unused) or greater than or equal to parameter

When txTrafficDescType is 7, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic; parameter 2 represents the SCR for
CLP equal to 0 with cell discard; parameter 3 represents the MBS
for CLP equal to 0 traffic; parameter 4 represents the CDVT; and
parameter 5 represents the requested shaping rate. A non-zero value
in parameter 5 overrides any value in parameter 1. This result is
used as the PCR. Parameters 1, 2 and 3 must be non-zero.
Parameter 1 must be greater than or equal to parameter 2. Parameter
5, must either be zero (unused) or greater than or equal to parameter
2.
When txTrafficDescType is 8, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic; parameter 2 represents the SCR for
CLP equal to 0 traffic with cell tagging; parameter 3 represents the
MBS for CLP equal to 0 traffic; parameter 4 represents the CDVT;
and parameter 5 represents the requested shaping rate. A non-zero
value in parameter 5 overrides any value in parameter 1. This result
is used as the PCR. Parameters 1, 2 and 3 must be non-zero.
Parameter 1 must be greater than or equal to parameter 2. Parameter
5, must either be zero (unused) or greater than or equal to parameter
2.
When txTrafficDescType is 9, parameter 1 represents the PCR;
parameter 2 represents the CDVT; parameter 3 represents the MCR;
parameter 4 and parameter 5 represent are not used and must be
zero. Parameter 1 must be non-zero and must be greater than or
equal to parameter 3. Parameter 3 may be optionally zero.
Whenever it is valid for PCR to be specified, parameter 5 may also
be used to specify a requested shaping rate. A non-zero value in
parameter 5 overrides the value in parameter 1 and is used as the
peak cell rate in calculations of CAC and shaping rate. When the
atmServiceCategory is availableBitRate (ABR), the shaping rate is
dynamically chosen, based on the ABR flow control mechanism, as
a value between the MCR and the PCR or the requested shaping
rate if applicable.
For txTrafficDescType 3, 4 and 5, the transmit traffic is shaped at
the next available shaping rate less than the PCR.
For txTrafficDescType 6, 7 and 8 if linear traffic shaping is selected,
the transmit traffic is shaped at the highest available rate which is
between PCR and SCR. However, if there is no available shaping
rate between PCR and SCR, traffic is shaped at the next rate above
the PCR.
For txTrafficDescType 6, 7 and 8 if inverse-UPC traffic shaping is
selected, the transmit traffic is shaped at a variable rate which
conforms to the PCR, SCR and MBS of the connection traffic
descriptor. Inverse-UPC traffic shaping is available only on ATM IP
cards. SEQUENCE OF AtmIfVccVcdTmTxTdpEntry .1.3.6.1.4.1.3764.1.1.30.114.5.2.2.456 |

atmIfVccVcdTmRxTdpTableThis attribute is a vector of four traffic parameters whose meanings
are defined by the rxTrafficDescType attribute. The values of peak
cell rate (PCR), sustained cell rate (SCR) and Minimum Cell Rate
(MCR) are expressed in cell/s. Maximum burst size (MBS) is
expressed in cells. The value of CDVT is expressed in
microseconds. The values of PCR, SCR, MCR, MBS and CDVT
are used for usage parameter control (UPC).
When rxTrafficDescType is 1 or 2, all of the parameters must be set
to zero (unused).
When rxTrafficDescType is 3, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic. Parameter 1 must be non-zero.
Parameters 2 and 3 must be set to zero (unused).
When rxTrafficDescType is 4, parameter 1 represents the PCR
for CLP equal to 0 and 1 traffic; parameter 2 represents the PCR for
CLP equal to 0 traffic with cell discard. Parameters 1 and 2 must be
non-zero. Parameter 3 must be set to zero (unused). Parameter 1
must be greater than or equal to parameter 2.
When rxTrafficDescType is 5, parameter 1 represents the PCR for

parameter 2 represents the CDVT; parameter 3 represents the MCR.
Parameter 4 is not used and must be zero. Parameter 1,must be non-
zero and must be greater than or equal to parameter 3. Parameter 3
may optionally be zero.
When rxTrafficDescType is any value from 3 through 8, parameter
4 represents the CDVT.
If the value of CDVT either in parameter 2 or in parameter 4 is zero,
the CDVT is taken from the CA defaults for the particular
atmServiceCategory of this connection.
On a CQC-based ATM card, when rxTrafficDescriptorType is 3
through 8, there are certain extreme combinations of
rxTrafficDescParm which are outside the capabilities of the UPC
hardware. The check prov command detects such cases and
generates an error message. If this happens, adjust the parameters
until they fall within the supported limits.
To calculate the limits, use the following formulae:
I1 = 1 000 000 000 / PCR
L1 = CDVT * 1000
I2 = 1,000,000,000 / SCR
L2 = CDVT + (MBS - 1) * (I2 - I1)
I1 and I2 must be less than or equal to 335,523,840. I1 + L1 must
be less than or equal to 1,342,156,800. I2 + L2 must be less than or
equal to 1,342,156,800. Note that I2 and L2 only apply when the
rxTrafficDescriptorType is 6 through 8.
If the values of I1, L1, I2 or L2 are closer to the limits described
above, a further restriction applies. Specifically, if either:
I1 > 41,940,480 or
I2 > 41,940,480 or
I1 + L1 > 167,769,600 or
I2 + L2 > 167,769,600
then both I1 and I2 must be greater than 20,480.
Parameter 5 of the rxTrafficDescParm is always unused.
If the rxTrafficDescType is sameAsTx, the values provisioned in
this attribute are ignored. The traffic parameters for the receive
direction are taken from the txTrafficDescParm. SEQUENCE OF AtmIfVccVcdTmRxTdpEntry .1.3.6.1.4.1.3764.1.1.30.114.5.2.2.457 |

atmIfVccVcdAtmServiceCategoryThis attribute is migrated to the AtmTmProv group.
This attribute specifies the ATM service category for both directions
of the connection.
The value derivedFromBBC may only be used if the SrcPvc
component is provisioned under this Vcc.Otherwise a specific ATM
service category must be specified.
If this attribute is set to derivedFromBBC, the Broadband Bearer
Capability (BBC) and bestEffort attributes are used to determine the
atmServiceCategory of this connection.
If this attribute is set to other than derivedFromBBC, the value of
this attribute is used to override the provisioned BBC Information
Element parameters. In those cases, the BBC attributes are not used.
The constantBitRate service category is intended for real time
applications, that is those requiring tightly constrained delay and
delay variation, as would be appropriate for voice and video
applications. The consistent availability of a fixed quantity of
bandwidth is considered appropriate for CBR service. Cells which
are delayed beyond the value specified by Cell Transfer Delay are
assumed to be of significantly reduce value to the application.
The rtVariableBitRate service category is intended for real time
applications, that is those requiring tightly constrained delay and
delay variation, as would be appropriate for voice and video
applications. Sources are expected to transmit at a rate which varies
with time. Equivalently, the source can be described as 'bursty'.
Cells which are delayed beyond the value specified by CTD are
assumed to be of significantly reduced value to the application. Real
time VBR service may support statistical multiplexing of real time
sources.
The nrtVariableBitRate service category is intended for non-real
time applications which have bursty traffic characteristics and which
can be characterized in terms of a PCR, SCR, and MBS. For those
cells which are transferred within the traffic contract, the application
expects a low cell loss ratio. For all connections, it expects a bound
on the mean cell transfer delay. Non-real time VBR service may
support statistical multiplexing of connections.
The unspecifiedBitRate service is intended for non-real time
applications; that is, those not requiring tightly constrained delay
and delay variation. UBR sources are expected to be bursty. UBR
service supports a high degree of statistical multiplexing among
sources. UBR service does not specify traffic related service
guarantees. No numerical commitments are made with respect to
the cell loss ratio experienced by a UBR connection, or as to the
cell transfer delay experienced by cells on the connection.rwobsolete Enumeration .1.3.6.1.4.1.3764.1.1.30.114.5.2.110.1.42 |

atmIfVccVcdBearerClassBbcThis attribute is migrated to the AtmTmProv group.
This attribute specifies the bearer capability. This attribute is only
used for SPVC and SPVP connections. It is one of the Broadband
Bearer Capability (BBC) attributes. The purpose of the BBC
information element is to indicate a requested broadband
connection-oriented bearer service to be provided by the network.
The value derivedFromServiceCategory specifies that the actual
value which is used for this connection is derived from the value of
the atmServiceCategory. Either, this attribute must be set to
derivedFromServiceCategory, or the atmServiceCategory attribute
must be set to derivedFromBBC, but not both.
Class a service is a connection-oriented, constant bit rate ATM
transport service. Class a service has end to end timing
requirements and may require stringent cell loss, cell delay and cell
delay variation performance.When a is set, the user is requesting
more than an ATM only service. The network may look at the AAL
to provide interworking based upon its contents.
Class c service is a connection-oriented, variable bit rate ATM
transport service. Class c service has no end-to-end timing
requirements. When c is set, the user is requesting more than an
ATM only service. The network interworking function may look at
the AAL and provide service based on it.
Class x service is a connection-oriented ATM transport service
where the AAL, trafficType (vbr or cbr) and timing requirements
are user defined (that is, transparent to the network).When x is set
the user is requesting an ATM only service from the network.
Class vp service is used to specify a transparent VP service. When
the value of this attribute is vp, the user is requesting an ATM only
service from the network. In this case, the network shall not process
any higher layer protocol. This service differs from class x service
in that with the class vp service both the VCI field (except or VCI
values 0, 3, 4, and 6 through 15) and Payload Type field are
transported transparently by the network. This attribute value is
only applicable to SPVP connections.rwobsolete Enumeration .1.3.6.1.4.1.3764.1.1.30.114.5.2.110.1.71 |
atmIfVccVcdTransferCapabilityBbcThis attribute is migrated to the AtmTmProv group.
This attribute specifies the transfer capability for this connection.
Uni 3.0/3.1 traffic type and end-to-end timing parameters are
mapped into this parameter as follows:
<transferCapability: TrafficType, Timing>
0: NoIndication, NoIndication
1: NoIndication, yes
2: NoIndication, no
5: CBR, yes
8: VBR, NoIndication
9: VBR, yes
10: VBR, no
NotApplicable specifies that the user does not want to specify the
transfer capability.
The CBR traffic type refers to traffic offered on services such as a
constant bit rate video service or a circuit emulation.
The VBR traffic type refers to traffic offered on services such as
packetized audio and video, or data.
The value no indication for traffic type is used if the user has not set
the traffic type; similarly for end-to-end timing.
The value yes for end-to-end timing indicates that end-to-end
timing is required.
The value no for end-to-end timing indicates that end-to-end timing
is not required.
The value derivedFromServiceCategory specifies that the actual

atmIfVccVcdFwdFrameDiscardThis attribute specifies the activation of frame discard functionality
in the forward data direction, at relay points, for this connection. It
applies to each hop of the connection. Frame discard functions
should not be requested if this connection is not transferring frame
(AAL5) traffic. Setting the value to indicated for any other traffic
type results in all traffic being discarded.
If this connection point is a permanent (provisioned) VCC mid-
point, this attribute specifies whether the Partial Packet
Discard (PPD) function is to be enabled or disabled in the transmit
direction at this connecting point. The PPD function allows the
connecting point to discard the remainder of a cell-forwarded AAL5
frame if one cell of this frame has been discarded. The PPD
function increases the 'goodput' of the link, since cells which are
only going to be discarded by the AAL5 reassembly are not
transmitted.
At a permanent VCC connecting point which is not a connection
endpoint, when this attribute is set to indicated, the PPD function is
applied to transmit traffic at this connecting point. It should not be
indicated for connections whose end points are not performing
AAL5 segmentation and reassembly. When this attribute is set to
notIndicated, the PPD feature is not applied to transmit traffic at
this connecting point.
At a SPVC origin on a PNNI interface, a value of indicated
specifies that frame discard is requested in the forward direction.
The frame discard function for SPVCs consists of PPD at the SPVC
origin and at all intermediate connecting points. When this attribute
is set to notIndicated, forward frame discard is not requested in the
SPVC call setup. Thus PPD is not enabled at the SPVC origin nor at
any intermediate connecting point.
At all points along a VPC, this setting is ignored.
At a permanent VCC connection endpoint, this value is ignored. If
AAL5 segmentation and reassembly has been requested, PPD and
Early Packet Discard (EPD) are automatically enabled.

atmIfVccVcdBwdFrameDiscardThis attribute specifies the activation of frame discard functionality
in the backward data direction, at relay points, for this connection.
It applies to each hop of the connection. Frame discard functions
should not be requested if this connection is not transferring frame
(AAL5) traffic. Setting the value to indicated for any other traffic
type results in all traffic being discarded.
If this connection point is a permanent (provisioned) VCC mid-
point, this attribute specifies whether the Partial Packet Discard
(PPD) function is to be enabled or disabled in the receive direction
at this connecting point. The PPD function allows the connecting
point to discard the remainder of a cell-forwarded AAL5 frame if
one cell of this frame has been discarded. The PPD function
increases the 'goodput' of the link, since cells which are only going
to be discarded by the AAL5 reassembly are not received.
At a permanent VCC connecting point which is not a connection
endpoint, when this attribute is set to indicated, the PPD function is
applied to receive traffic at this connecting point. It should not be
indicated for connections whose end points are not performing
AAL5 segmentation and reassembly. When this attribute is set to
notIndicated, the PPD feature is not applied to receive traffic at this
connecting point.
At a SPVC origin on a PNNI interface, a value of indicated
specifies that frame discard is requested in the backward direction.
The frame discard function for SPVCs consists of PPD at the SPVC
origin and at all intermediate connecting points. When this attribute
is set to notIndicated, backwards frame discard is not requested in
the SPVC call setup. Thus PPD is not enabled at the SPVC origin
nor at any intermediate connecting point.
At all points along a VPC, this setting is ignored.
At a permanent VCC connection endpoint, this value is ignored. If
AAL5 segmentation and reassembly has been requested, PPD and
Early Packet Discard (EPD) are automatically enabled.

atmIfVccVcdTxTdpTableThis attribute is migrated to the AtmTmProv group.
This attribute is a vector of five traffic parameters whose meanings
are defined by the txTrafficDescType attribute. The values of peak
cell rate (PCR), sustained cell rate (SCR) and requested shaping rate
are expressed in cell/s. Maximum burst size (MBS) is expressed in
cells. CDVT is expressed in microseconds. The values of PCR,
SCR, MBS and CDVT are used for connection admission control
(CAC). The value of CDVT is only used for connections where the
atmServiceCategory is constantBitRate. For all other values of
atmServiceCategory, CDVT is ignored. The values of PCR, SCR
and requested shaping rate are used to determine the actual shaping
rate where traffic shaping is enabled.
When txTrafficDescType is 1 or 2, all of the parameters must be set
to zero.
When txTrafficDescType is 3, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic; parameter 4 represents the CDVT; and
parameter 5 represents the requested shaping rate. A non-zero value
in parameter 5 overrides any value in parameter 1. This result is
used as the PCR. Parameter 1 must be non-zero. Parameters 2 and 3
must be zero.
When txTrafficDescType is 4, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic with cell discard; parameter 2
represents the PCR for CLP equal to 0 traffic; parameter 4
represents the CDVT; and parameter 5 represents the requested
shaping rate. A non-zero value in parameter 5 overrides any value in
parameter 1. This result is used as the PCR. Parameter 1 must be
greater than or equal to parameter 2. Parameters 1 and 2 must be
non-zero. Parameter 3 must be zero.
When txTrafficDescType is 5, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic with cell tagging; parameter 2
represents the PCR for CLP equal to 0 traffic; parameter 4
represents the CDVT; and parameter 5 represents the requested
shaping rate. A non-zero value in parameter 5 overrides any value in
parameter 1. This result is used as the PCR. Parameter 1 must be
greater than or equal to parameter 2. Parameters 1 and 2 must be
non-zero. Parameter 3 must be zero.
When txTrafficDescType is 6, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic; parameter 2 represents the SCR for
CLP equal to 0 and 1 traffic; parameter 3 represents the MBS for
CLP equal to 0 and 1 traffic; parameter 4 represents the CDVT; and
parameter 5 represents the requested shaping rate. A non-zero value
in parameter 5 overrides any value in parameter 1. This result is
used as the PCR. Parameters 1, 2 and 3 must be non-zero.
Parameter 1 must be greater than or equal to parameter 2. Parameter
5, must either be zero (unused) or greater than or equal to parameter
2.
When txTrafficDescType is 7, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic; parameter 2 represents the SCR for
CLP equal to 0 with cell discard; parameter 3 represents the MBS
for CLP equal to 0 traffic; parameter 4 represents the CDVT; and
parameter 5 represents the requested shaping rate. A non-zero value
in parameter 5 overrides any value in parameter 1. This result is
used as the PCR. Parameters 1, 2 and 3 must be non-zero.
Parameter 1 must be greater than or equal to parameter 2. Parameter
5, must either be zero (unused) or greater than or equal to parameter
2.
When txTrafficDescType is 8, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic; parameter 2 represents the SCR for
CLP equal to 0 traffic with cell tagging; parameter 3 represents the
MBS for CLP equal to 0 traffic; parameter 4 represents the CDVT;
and parameter 5 represents the requested shaping rate. A non-zero
value in parameter 5 overrides any value in parameter 1. This result
is used as the PCR. Parameters 1, 2 and 3 must be non-zero.
Parameter 1 must be greater than or equal to parameter 2. Parameter
5, must either be zero (unused) or greater than or equal to parameter
2.
Whenever it is valid for PCR to be specified, parameter 5 may also
be used to specify a requested shaping rate. A non-zero value in
parameter 5 overrides the value in parameter 1 and is used as the
peak cell rate in calculations of CAC and shaping rate.
For txTrafficDescType 3, 4 and 5, the transmit traffic is shaped at
the next rate less than the PCR.
For txTrafficDescType 6, 7 and 8, the transmit traffic is shaped at
the highest available rate which is between PCR and SCR.
However, if there is no available shaping rate between PCR and
SCR, traffic is shaped at the next rate above the PCR.obsolete SEQUENCE OF AtmIfVccVcdTxTdpEntry .1.3.6.1.4.1.3764.1.1.30.114.5.2.297 |

This attribute is a vector of four traffic parameters whose meanings
are defined by the rxTrafficDescType attribute. The values of peak
cell rate (PCR) and sustained cell rate (SCR) are expressed in
cell/s. Maximum burst size (MBS) is expressed in cells. The value
of CDVT is expressed in microseconds. The values of PCR, SCR,
MBS and CDVT are used for usage parameter control (UPC).
When rxTrafficDescType is 1 or 2, all of the parameters must be set

CLP equal to 0 traffic with cell tagging; parameter 3 represents the
MBS for CLP equal to 0 traffic. Parameter 1, 2 and 3 must be non-
zero. Parameter 1 must be greater than or equal to parameter 2.
When rxTrafficDescType is any value from 3 through 8, parameter
4 represents the CDVT. If this value is zero, the CDVT is taken
from the ConnectionAdministrator defaults for the particular
atmServiceCategory of this connection.
When rxTrafficDescriptorType is 3 through 8, there are certain
extreme combinations of rxTrafficDescParm which are outside the
capabilities of the UPC hardware. The check prov command detects
such cases and generates an error message. If this happens, adjust
the parameters until they fall within the supported limits.
To calculate the limits, use the following formulae:
I1 = 1 000 000 000 / PCR
L1 = CDVT * 1000
I2 = 1 000 000 000 / SCR
L2 = CDVT + (MBS - 1) * (I2 - I1)
I1 and I2 must be less than or equal to 335 523 840. I1 + L1 must
be less than or equal to 1 342 156 800. I2 + L2 must be less than or
equal to 1 342 156 800. Note that I2 and L2 only apply when the
rxTrafficDescriptorType is 6 through 8.
If the values of I1, L1, I2 or L2 are closer to the limits described
above, a further restriction applies. Specifically, if either:
I1 > 41 940 480 or
I2 > 41 940 480 or
I1 + L1 > 167 769 600 or
I2 + L2 > 167 769 600
then both I1 and I2 must be greater than 20 480.
Parameter 5 of the rxTrafficDescParm is always unused.
If the rxTrafficDescType is sameAsTx, the values in this attribute
are taken from the txTrafficDescParm.obsolete SEQUENCE OF AtmIfVccVcdRxTdpEntry .1.3.6.1.4.1.3764.1.1.30.114.5.2.298 |

atmIfVccTestFrmTypesThis attribute specifies the types of the test frames to be transmitted
during the ATM connection test. It must contain at least one of the
following:
loading: A set of 'loading frames' is circulated over the link as
rapidly as possible. This frame type should be selected when the
test is intended to verify the operation of the connection under a
specified load. These frames are not checked for bit errors.
verification: A single 'verification frame' is transmitted over the
link; when the frame is returned, its contents are verified and the
next verification frame in the series is transmitted. This frame type
should be selected when the test is intended to verify that frames are
not being corrupted as they pass over the connection.

atmIfVccTestBandwidthElasticThis attribute specifies whether the connection (VCC) should be
configured with elastic bandwidth or not. Elastic bandwidth is of
importance in conjuction with IMA links, where some links fail and
the resulting bandwidth is less than the requested bandwidth for all
connections. In that case, some connections may be reduced in
bandwidth based on the setting of the bwElastic attribute.
If this attribute is set to yes, the Test application signals to the
connection that the bandwidth for this connection is elastic, and
may be reduced in the case of IMA link failures. If the bandwidth is
reduced, the rate of test cells which can be handled by the
connection will also be reduced.
If this attribute is set to no, the Test application signals to the
connection that the bandwidth for this connection must be
maintained at the requested level. If the connection cannot maintain
the full bandwidth, the connection may be released (cleared) based
on the holding priority of the connection.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.114.5.6.110.1.60 |
atmIfVccTestOverrideHoldingPriorityThis attribute specifies the override holding priority which should

priority is of importance in conjuction with IMA links, where some
links fail and the resulting bandwidth is less than the requested
bandwidth for all connections. In that case, some connections may
be released based on the connection's holding priority.
Zero (0) is thie highest holding priority, and four (4) is the lowest
priority. A setting of zero to four overrides whatever holding
priority that has been configured at the connection (VCC). A setting
of noOverride means that the connection should use its internally

atmIfVccTmAbrRateDecreaseFactorThis attribute is applicable and is displayed only for connections for
which the operational Tm abrConnectionType is displayed as
sourceDest or virtualSourceDest.
This attribute indicates the Rate Decrease Factor (RDF) for this
connection. The RDF value is computed by using the operational
value of this attribute, n, as 2 to the inverse power n. For example, if
the value of this attribute is 8, RDF is 2E-8 = 1/256.
RDF controls the amount by which the cell transmission rate may
decrease upon receipt of a backward Resource Management (RM)
cell. For example, if a backward RM cell is received with the
Congestion Indication (CI) field set to 1, the Allowed Cell Rate
(ACR) value would be reduced by the amount (RDF*ACR). The
ACR is not allowed to fall below the Minimum Cell Rate (MCR), in
which case the ACR is set to MCR.

atmIfVccTmAbrRateIncreaseFactorThis attribute is applicable and is displayed only for connections for
which the operational Tm abrConnectionType is displayed as
sourceDest or virtualSourceDest.
This attribute indicates the Rate Increase Factor (RIF) for this
connection. The RIF value is computed by using the operational
value of this attribute, n, as 2 to the inverse power n. For example, if
the value of this attribute is 6, RIF is 2E-6 = 1/64.
RIF controls the amount by which the cell transmission rate may
increase upon receipt of a backward Resource Management (RM)
cell. For example, if a backward RM cell is received with the
Congestion Indication (CI) and the No Increase (NI) fields both set
to 0, the Allowed Cell Rate (ACR) value would be increased by the
amount (RIF*ACR). The ACR is not allowed to exceed the Peak
Cell Rate (PCR), in which case the ACR is set to PCR.

This attribute indicates the TRM parameter for this connection.
TRM provides an upper bound on the time interval between forward
Resource Management (RM) cells for an ABR source. Since the last
forward RM cell was sent, if at least TRM time has elapsed since
and at least 2 other cells have been sent, the next cell to be
transmitted would be a forward RM cell.

Parameters Information Element.ro Unsigned32 (781 | 1563 | 3125 | 6250 | 12500 | 25000 | 50000 | 100000) .1.3.6.1.4.1.3764.1.1.30.114.5.7.2.110.1.16 |
atmIfVccTmAbrCutoffDecreaseFactorThis attribute is applicable and is displayed only for connections for
which the operational Tm abrConnectionType is displayed as
sourceDest or virtualSourceDest.
This attribute indicates the Cutoff Decrease Factor (CDF) parameter
for this connection. When the value of this attribute is non-zero,
CDF is computed as the inverse of the value. For example, if the
value is 32, the value of CDF is 1/32. When the value of this
attribute is 0, CDF is also zero.
CDF controls the decrease in the Allowed Cell Rate (ACR)
associated with the forwardRmCellLimit attribute, the limit of the
number of forward Resource Management (RM) cells which may
be sent in the absence of received backward RM cells. When this
limit is crossed, the ACR value would be decreased by the amount
(CDF*ACR). The ACR is not allowed to fall below the Minimum
Cell Rate (MCR), in which case the ACR is set to MCR.
For nailed-up connections, this attribute is determined by the

This attribute indicates the Allowed Cell Rate Decrease Time Factor
(ADTF) parameter for this connection.
ADTF is the time interval permitted between sending forward
Resource Management (RM) cells before the Allowed Cell Rate
(ACR) is decreased to initialCellRate. In other words, if the source
does not transit a forward RM cell for the period specified by adtf, it
reduces its ACR to the value of its initialCellRate.

CRM is the limit of the number of forward Resource Management
(RM) cells which may be sent in the absence of received backward
RM cells. When this limit is crossed, the Allowed Cell Rate (ACR)
value would be decreased by the amount (CDF*ACR), where CDF
is determined by the cutoffDecreaseFactor. The ACR is not allowed
to fall below the Minimum Cell Rate (MCR), in which case the
ACR is set to MCR.

The congestion state of a queue is indicated by a numeric value
ranging from 0 to 3. When a queue is in a congested state x, only
traffic with discard priority (DP) 0 to x are enqueued. Traffic with
DP > x is discarded.
For example, if the congestion state is 3, there is no congestion and
all traffic is enqueued. Likewise, when the congestion state is 0,
there is maximum congestion and only traffic with DP=0 is
enqueued on that queue.

atmIfVccTmAtmServiceCategoryThis attribute indicates the ATM service category used for traffic in
both directions of the connection. This attribute does not apply to
Virtual Link VPTs and will always be displayed as
constantBitRate.
The constantBitRate service category is intended for real time
applications, that is, those requiring tightly constrained delay and
delay variation, as would be appropriate for voice and video
applications. The consistent availability of a fixed quantity of
bandwidth is considered appropriate for CBR service. Cells which
are delayed beyond the value specified by Cell Transfer Delay are
assumed to have significantly reduced value for the application.
The rtVariableBitRate service category is intended for real time
applications; that is those requiring tightly constrained delay and
delay variation, as would be appropriate for voice and video
applications. Sources are expected to transmit at a rate which varies
with time. Equivalently, the source can be described as 'bursty'.
Cells which are delayed beyond the value specified by Cell Transfer
Delay are assumed to be of significantly reduced value to the
application. Real time VBR service may support statistical
multiplexing of real time sources.
The nrtVariableBitRate service category is intended for non-real
time applications which have bursty traffic characteristics and which
can be characterized in terms of a PCR, SCR, and MBS. For those
cells which are transferred within the traffic contract, the application
expects a low cell loss ratio. For all connections, it expects a bound
on the mean cell transfer delay. Non-real time VBR service may
support statistical multiplexing of connections.
The availableBitRate service is an ATM layer service category for
which the limiting ATM layer transfer characteristics provided by
the network may change subsequent to connection establishment.
ABR service has a flow control mechanism which supports several
types of feedback to control the source rate in response to changing
ATM layer transfer characteristics. ABR service is not intended to
support real-time applications.
The unspecifiedBitRate service is intended for non-real time
applications, that is those not requiring tightly constrained delay
and delay variation. UBR sources are expected to be bursty. UBR
service supports a high degree of statistical multiplexing among
sources. UBR service does not specify traffic related service
guarantees. No numerical commitments are made with respect to
the cell loss ratio experienced by a UBR connection, or as to the
cell transfer delay experienced by cells on the connection.ro Enumeration .1.3.6.1.4.1.3764.1.1.30.114.5.7.100.1.62 |
atmIfVccTmTrafficShapingThis attribute indicates the traffic shaping state of the connection.
A value of notApplicable indicates that traffic shaping is not
applicable or not supported for this connection. This is the case:
- when the txTrafficDescType is 1 or 2.
- for standard Vpt Vccs and basic Vpts.
- for CQC-based ATM cards, when the atmServiceCategory is
constantBitRate.
In these cases, the value of notApplicable is set regardless of
whether traffic shaping is enabled or disabled in the provisioning
data.
A value of disabled indicates that traffic shaping is applicable and
supported for the type of connection but has been turned off in the
provisioning data.
A value of linear or inverseUpc indicates that traffic shaping is
applicable and supported for the type of connection and has been
turned on in the provisioning data. This is the only case that
indicates that traffic shaping is performed on the connection. In this
case, the actual shaping rate is reflected in the txTrafficDescParm
attribute, parameter number 4. A value of linear indicates that
traffic is being shaped at the constant rate indicated in
txTrafficDescParm 4.
A value of inverseUpc is possible only on ATM IP cards. This value
indicates that the shaper strictly conforms to the requirements of a
dual leaky bucket UPC enforcer. This value is indicated if traffic
shaping is enabled, and the txTrafficDescType for this connection is
6, 7 or 8.
Traffic shaping for connections with atmServiceCategory as
availableBitRate (txTrafficDescType 9) depends upon the
abrConnectionType attribute. If abrConnectionType is sourceDest
or virtualSourceDest, the value of this attribute is dynamic. If
abrConnectionType is erSwitch or efciSwitch, this attribute is
notApplicable.ro Enumeration .1.3.6.1.4.1.3764.1.1.30.114.5.7.100.1.70 |
atmIfVccTmBearerClassBbcThis attribute indicates the bearer capability for this connection.
Class a service is a connection-oriented, constant bit rate ATM
transport service. Class a service has end to end timing
requirements and may require stringent cell loss, cell delay and cell
delay variation performance.When a is displayed, the user is
requesting more than an ATM only service. The network may look
at the AAL to provide interworking based upon its contents.
Class c service is a connection-oriented, variable bit rate ATM
transport service. Class c service has no end-to-end timing
requirements.When c is displayed, the user is requesting more than
an ATM only service. The network interworking function may look
at the AAL and provide service based on it.
Class x service is a connection-oriented ATM transport service
where the AAL, trafficType (cbr or vbr), and timing requirements
are user defined (that is, transparent to the network). When the
value of this attribute is x, the user is requesting an ATM only
service from the network. In this case, the network shall not process
any higher layer protocol.
Class vp service is used to indicate a transparent VP service when
the user is requesting an ATM only service from the network. In this
case, the network does not process any higher layer protocol. This
service differs from class x service in that with the class vp service
both the VCI field (except for VCI values 0, 3, 4, and 6 through 15)
and Payload Type field are transported transparently by the network.
This attribute value is only applicable to SPVP and SVP

The CBR traffic type refers to traffic offered on services such as a
constant bit rate video service or a circuit emulation.
The VBR traffic type refers to traffic offered on services such as
packetized audio and video, or data.
The value NoIndication for traffic type is used if the user has not set
the traffic type; similarly for end-to-end timing.
The value yes for end-to-end timing indicates that end-to-end
timing is required for the connection.
The value no for end-to-end timing indicates that end-to-end timing

atmIfVccTmUnshapedTransmitQueueingThis attribute indicates the unshaped transmit queuing state of the
connection.
A value of common indicates that transmit traffic is being enqueued
onto the common transmit queue for this service category.
The txQueueLength attribute indicates the current length of the
common transmit queue.
A value of fifo indicates that transmit traffic is being queued in a
first-in-first-out basis for this service category. This is similar to
common queueing, but the txQueueLength attribute indicates the
number of cells in this connection queue. A value of fifo will only
be indicated for connections on ATM IP cards with
atmServiceCategory of nrtVbr or ubr.
A value of perVc indicates that transmit traffic is being enqueued
onto a per-VC queue for this connection.
A value of notApplicable indicates that transmit traffic is being
shaped for this connection, or that unshaped transmit queuing is not

atmIfVccTmWeightThis attribute indicates the relative weight of this unshaped
connection. Connections with a larger weight get a larger proportion
of the link bandwidth, or in the case of standard Vpt Vccs, the Vpt
bandwidth.
For all but standard Vpt Vccs, the default connection weight is
determined by the weight policy for a service category and the
traffic descriptor for a connection. For standard Vpt Vccs, the
default connection weight is determined by the Vcc's service
category.
For CQC-based ATM cards, this attribute is not applicable and is
not displayed.
A value from 1 to 4095 indicates an actual weight. The value
upToQueueLimit indicates that the weight of a connection is up to
the transmit queue limit for this connection. upToQueueLimit is

atmIfVccTmUsageParameterControlThis attribute indicates the UPC state of the connection.
A value of notApplicable indicates that UPC is not applicable or not
supported for the connection. This is the case:
- when the connection's rxTrafficDescType is 1 or 2.
- for standard Vpt Vccs and basic Vpts.
A value of notApplicable is set regardless of whether UPC is
disabled or enabled in provisioning data.
A value of disabled indicates that UPC is applicable and supported
for the type of connection but has been turned off in the
provisioning data.
A value of enforced indicates that UPC is actively checking
conformance for the connection and is discarding or tagging cells
which do not conform to the connection traffic contract. The traffic
descriptor parameters used for UPC conformance are reflected in
the rxTrafficDescParms of the connection. On ATM IP cards, the
counts of UPC violations are visible in the Vcc, Vpc, or Vpt
rxUpcViolationsOnEnforcer1 or rxUpcViolationsOnEnforcer2
attributes.
ATM IP cards provide the ability to monitor UPC violations without
tagging or discarding. A value of monitored indicates that UPC is
actively checking conformance for the connection and counting the
violations, but is not discarding or tagging cells which do not
conform to the connection traffic contract. The traffic descriptor
parameters used for UPC conformance are reflected in the
rxTrafficDescParms of the connection. The counts of UPC
violations are visible in the Vcc, Vpc, or Vpt
rxUpcViolationsOnEnforcer1 or rxUpcViolationsOnEnforcer2

atmIfVccTmBandwidthElasticThis attribute is only of importance for connections which are
carried on a link with a variable bandwidth. For example, the
bandwidth may be reduced in the event that one or more physical
links in the IMA group fail, such that the originally requested
bandwidth cannot be maintained. This attribute shows whether the
application (for example, Trunk) running on this connection can
continue to operate if the bandwidth is reduced. If the bandwidth is
reduced, the amount by which it is reduced is displayed in the
bandwidthReduction attribute.
A value of yes, indicates that this connection is elastic, and the
bandwidth may be reduced but the connection is not released.
A value of no indicates that the bandwidth for this connection is not
reduced in the event of link bandwidth reduction. However, this
connection may be released based on its holdingPriority.
Bandwidth elasticity has no effect for connections which have an

atmIfVccTmAbrConnectionTypeThis attribute indicates the type of ABR behavior which is in effect
at this connection. This attribute is only applicable if the
atmServiceCategory attribute is availableBitRate. If the
atmServiceCategory attribute is not availableBitRate, or if the
connection is not active, this attribute value is displayed as
notApplicable.
For CQC-based ATM cards, the only possible values are
notApplicable, efciSwitch or nonAbrInterworking. In EFCI
marking mode, the Explicit Forward Congestion Indication (EFCI)
field in the data cell headers is used to indicate transmit queue
congestion.
For ATM IP cards, if the connectionPointType is displayed as
connectionEndPoint, this attribute has the value sourceDest. In this
mode, the ABR Source and Destination behavior is in effect at this
connection. This attribute is also sourceDest in the case where the
next hop connection is specified as nonAbrInterworking. The next
hop connection is the Vcc or Vpc identified by the nextHop attribute
of the Nrp or Rp component.
If the connectionPointType is not connectionEndPoint, the value of
this attribute depends upon the abrConnectionType provisioning
and the card type to which the traffic is forwarded on the backplane.
The default abrConnectionType is provisioned at the CA Abr
abrConnectionType attribute, and may be overridden for a
provisioned connection in the Vcd Tm abrConnectionType or Vpd
Tm abrConnectionType attribute. If the CA Abr abrConnectionType
attribute is virtualSourceDest at either one of the two connection
points, and if both the connection points are defined on ATM IP
cards, virtual source and destination behavior is applied to the
connection. In this instance, the attribute displays the value
virtualSourceDest.
This attribute has the value erSwitch if ABR explicit rate
functionality is in effect at this connection. In this mode, the switch
may modify the Explicit Rate (ER) field of backward Resource
Management (RM) cells to indicate the status of congestion at this
connection point.
This attribute has the value nonAbrInterworking in the case where
this connection point is functioning as an SPVC origin for an ABR
connection where the link side of this connection is configured as a
non-ABR ATM service category. This means that there are no RM
cells on the link side of this connection, and that the next hop

When txTrafficDescType is 3, 4, 5, 6, 7, or 8, parameter 4 reflects
the actual shaping rate in cell/s for this connection. For CQC-based
ATM cards, the set of available shaping rates is based on the
number of interfaces doing shaping (attribute
perVcQueueInterfaces), and the shapingScalingFactor attribute of
the Arc Cqc Override component. A rate of zero (0) indicates that
shaping is not performed, or that the interface is down.
When txTrafficDescType is 9, parameter 1 represents the PCR;
parameter 2 represents the Cell Delay Variation Toleration (CDVT);
parameter 3 represents the Minimum Cell Rate (MCR); the meaning
of parameter 4 depends upon the value of the abrConnectionType
attribute. if abrConnectionType is sourceDest or
virtualSourceDest, parameter 4 represents the Allowed Cell Rate
(ACR); If abrConnectionType is erSwitch, parameter 4 represents
the Explicit Rate (ER); and if abrConnectionType is efciSwitch,
parameter 4 reflects the actual shaping rate in cell/s for this
connection.
When txTrafficDescType is 3, 4, 5, 6, 7, 8, or 9, parameter 5 reflects
the equivalent cell rate in cell/s for this connection as determined by
the Connection Admission Control (CAC) algorithm. The
equivalent cell rate is useful in determining the admission
characteristics of this connection. SEQUENCE OF AtmIfVccTmTxTdpEntry .1.3.6.1.4.1.3764.1.1.30.114.5.7.451 |

atmIfVccRxOamCellCongestionStateThis attribute contains the current state of the receive side OAM cell
congestion for this connection. Its value reflects whether the rate of
received OAM cells for this connection is below a specified
threshold. The connection maintains a count of the number of OAM
cells which are terminated per second. Once that count exceeds the
specified threshold, extraction of all OAM cells for this connection
is disabled for a period of one minute. This is a congestion
management mechanism to prevent the processor from being
overloaded with handling OAM cells for a particular connection.
This mechanism ensures that tasks, such as trunks obtain enough
processor cycles to remain in service, and are not adversely affected
by excessive rate of OAM cells on a particular connection.
The value is good when the rate of received OAM cells is less than
the allowed threshold.
The value is bad when the arrival rate has exceeded the allowed
threshold. It remains bad for one minute, before returning to good
again. During this timeout, extraction of all OAM cells is disabled
for this connection. As a result, other loopback failure conditions
may occur.
The value is unknown when the application has not yet begun to
use this connection. An example is the Test component before a test
has been started.
Each type of OAM cell is counted separately. The threshold for AIS
cells is three cells per second. If more than three AIS cells are
received within a one second interval, this attribute is set to bad.
The threshold for RDI cells and each loopback type is also three,
but the threshold for trace cells is 250 per second.
The state of this attribute has no direct effect on the value of the

This attribute indicates the congestion state of the transmit queue
for this connection. If the connection has traffic shaping disabled,
then this attribute displays the common queue congestion state. If
traffic shaping is enabled, then this attribute displays the per-VC
queue congestion state.
The congestion state of a queue is indicated by a numeric value
ranging from 0 to 3. When a queue is in a congested state x, only
traffic with discard priority (DP) 0 to x are enqueued. Traffic with
DP > x is discarded.
Therefore, if the congestion state is 3, there is no congestion and all
traffic is enqueued. Likewise, when the congestion state is 0, there
is maximum congestion and only traffic with DP=0 is enqueued on
that queue.roobsolete INTEGER .1.3.6.1.4.1.3764.1.1.30.114.5.130.1.33 |
atmIfVccHoldingPriorityThis attribute is HISTORICAL. Please refer to the attribute of the

connections are held and which are released. Holding priority 4
connections are the first to be released. Holding priority 0
connections are the last to be released. Some applications, for
example Vcc Test, may override the provisioned holding priority.
A value of notApplicable is displayed when this is an elastic
connection. Holding priority does not apply to bandwidth elastic
connections.

atmIfVccAtmServiceCategoryThis attribute is HISTORICAL. Please refer to the attribute of the
same name in the group AtmTmOper.
This attribute indicates the ATM service category used for traffic in
both directions of the connection.
The constantBitRate service category is intended for real time
applications, that is, those requiring tightly constrained delay and
delay variation, as would be appropriate for voice and video
applications. The consistent availability of a fixed quantity of
bandwidth is considered appropriate for CBR service. Cells which
are delayed beyond the value specified by Cell Transfer Delay are
assumed to have significantly reduced value of the application.
The rtVariableBitRate service category is intended for real time
applications; that is those requiring tightly constrained delay and
delay variation, as would be appropriate for voice and video
applications. Sources are expected to transmit at a rate which varies
with time. Equivalently, the source can be described as 'bursty'.
Cells which are delayed beyond the value specified by Cell Transfer
Delay are assumed to be of significantly reduced value to the
application. Real time VBR service may support statistical
multiplexing of real time sources.
The nrtVariableBitRate service category is intended for non-real
time applications which have bursty traffic characteristics and which
can be characterized in terms of a PCR, SCR, and MBS. For those
cells which are transferred within the traffic contract, the application
expects a low cell loss ratio. For all connections, it expects a bound
on the mean cell transfer delay. Non-real time VBR service may
support statistical multiplexing of connections.
The unspecifiedBitRate service is intended for non-real time
applications, that is those not requiring tightly constrained delay
and delay variation. UBR sources are expected to be bursty. UBR
service supports a high degree of statistical multiplexing among
sources. UBR service does not specify traffic related service
guarantees. No numerical commitments are made with respect to
the cell loss ratio experienced by a UBR connection, or as to the
cell transfer delay experienced by cells on the connection.roobsolete Enumeration .1.3.6.1.4.1.3764.1.1.30.114.5.130.1.62 |
atmIfVccTrafficShapingThis attribute is HISTORICAL. Please refer to the attribute of the

when the atmServiceCategory is constantBitRate, or when the
txTrafficDescType is 1 or 2. In these cases, the value of
notApplicable is set regardless of whether traffic shaping is enabled
or disabled in the provisioning data.
A value of disabled indicates that traffic shaping is applicable and
supported for the type of connection but has been turned off in the
provisioning data.
A value of enabled indicates that traffic shaping is applicable and
supported for the type of connection and has been turned on in the
provisioning data. This is the only case that indicates that traffic

This attribute indicates the bearer capability for this connection.
Class a service is a connection-oriented, constant bit rate ATM
transport service. Class a service has end to end timing
requirements and may require stringent cell loss, cell delay and cell
delay variation performance.When a is displayed, the user is
requesting more than an ATM only service. The network may look
at the AAL to provide interworking based upon its contents.
Class c service is a connection-oriented, variable bit rate ATM
transport service. Class c service has no end-to-end timing
requirements.When c is displayed, the user is requesting more than
an ATM only service. The network interworking function may look
at the AAL and provide service based on it.
Class x service is a connection-oriented ATM transport service
where the AAL, trafficType (cbr or vbr) and timing requirements
are user defined (that is, transparent to the network). When the
value of this attribute is x, the user is requesting an ATM only
service from the network. In this case, the network shall not process
any higher layer protocol.
Class vp service is used to indicate a transparent VP service when
the user is requesting an ATM only service from the network. In this
case, the network does not process any higher layer protocol. This
service differs from class x service in that with the class vp service
both the VCI field (except for VCI values 0, 3, 4, and 6 through 15)
and Payload Type field are transported transparently by the network.

When txTrafficDescType is 3, 4, 5, 6, 7 or 8, parameter 4 reflects
the actual shaping rate in cell/s for this connection. This rate is one
of the set of available shaping rates for this type of ATM-FP, based
on the number of interfaces doing shaping (attribute
perVcQueueInterfaces), the provisioned cell rate, the
shapingScalingFactor attribute of the AtmResourceControl
component, and whether traffic shaping is enabled. A rate of zero
(0) indicates that shaping is not performed.
When txTrafficDescType is 3, 4, 5, 6, 7 or 8, parameter 5 reflects
the equivalent cell rate in cell/s for this connection as determined by
the Connection Admission Control (CAC) algorithm. The
equivalent cell rate is useful in determining the admission

atmIfVccTxQThreshTableThis attribute is HISTORICAL. Please refer to the attribute of the
same name in the group AtmTmOper.
This attribute indicates the queue limit and the discard thresholds
for the transmit queue of this connection.
The first element indicates the queue limit. Depending upon the
atmServiceCategory of the connection, the provisioned value of the
transmit queue limit is derived from the txQueueLimit attribute
under one of the subcomponents of the AtmIf CA component. If the
connection has traffic shaping disabled, then this attribute relates to
the common queue. If traffic shaping is enabled, then this attribute
relates to the per-VC queue.
The second element is the threshold that marks the transition from
congestion state 1 to congestion state 0. This is the threshold at
which traffic with discard priority (DP) = 1 is discarded. This
threshold is set approximately at 90 percent of the first parameter,
the operational queue limit.
The third element is the threshold that marks the transition from
congestion state 2 to congestion state 1. This is the threshold at
which traffic with DP = 2 is discarded. This threshold is set
approximately at 75 percent of the first parameter, the operational
queue limit.
The fourth element is the threshold that marks the transition from

atmIfVptVpdTmAbrInitialCellRateThis attribute specifies the Initial Cell Rate (ICR) parameter for this
connection. ICR is the rate at which a source should send initially
and after an idle period.
When this attribute is set to sameAsCa, the initial cell rate is
determined by the AtmIf CA Abr/0 icr attribute. When the value of
this attribute is set to useMcr, ICR is set to the same value as the
Minimum Cell Rate (MCR) for the connection.
When the value of this attribute is set to usePcr, ICR is set to the
same value as the Peak Cell Rate (PCR) for the connection.
If this attribute is specified less than the MCR of the connection,
then the MCR is used as the ICR. If this attribute is specified more
than PCR of the connection, then PCR is used as the ICR.
This attribute is ignored under all conditions where the operational
attribute abrConnectionType indicates erSwitch or efciSwitch.

atmIfVptVpdTmAbrTransientBufferExposureThis attribute specifies the Transient Buffer Exposure (TBE) for this
connection. TBE is the negotiated number of cells that the network
would like to limit the source to send during start-up periods, before
the first Resource Management (RM) cell returns.
TBE divided by fixedRoundTripTime determines an upper bound
for the operational value of initialCellRate, the rate at which a
source should send initially and after an idle period.
TBE divided by maxCellsPerRmCell specifies the operational value
of forwardRmCellLimit, the limit of the number of forward
Resource Management (RM) cells which may be sent in the
absence of received backward RM cells.
This attribute is ignored under all conditions where the operational

atmIfVptVpdTmAbrFixedRoundTripTimeThis attribute specifies the Fixed Round-Trip Time (FRTT)
parameter for this connection. FRTT is the sum of the fixed and
propagation delays from the source to a destination and back.
The value of transientBufferExposure divided by the value of FRTT
(in seconds) determines an upper bound for the operational value of
initialCellRate, the rate at which a source should send initially and
after an idle period.
This attribute is ignored under all conditions where the operational
attribute abrConnectionType indicates erSwitch or efciSwitch.rw Unsigned32 .1.3.6.1.4.1.3764.1.1.30.114.9.2.2.2.110.1.12 |
atmIfVptVpdTmAbrRateDecreaseFactorThis attribute specifies the Rate Decrease Factor (RDF) for this
connection. The RDF value is computed by using the provisioned
value of this attribute, n, as 2 to the inverse power n. For example, if
the value of this attribute is 8, RDF is 2E-8 = 1/256.
RDF controls the amount by which the cell transmission rate may
decrease upon receipt of a backward Resource Management (RM)
cell. For example, if a backward RM cell is received with the
Congestion Indication (CI) field set to 1, the Allowed Cell Rate
(ACR) value would be reduced by the amount (RDF*ACR). The
ACR is not allowed to fall below the Minimum Cell Rate (MCR), in
which case the ACR is set to MCR.

atmIfVptVpdTmAbrRateIncreaseFactorThis attribute specifies the Rate Increase Factor (RIF) for this
connection. The RIF value is computed by using the provisioned
value of this attribute, n, as 2 to the inverse power n. For example, if
the value of this attribute is 6, RIF is 2E-6 = 1/64.
RIF controls the amount by which the cell transmission rate may
increase upon receipt of a backward Resource Management (RM)
cell. For example, if a backward RM cell is received with the
Congestion Indication (CI) and the No Increase (NI) fields both set
to 0, the Allowed Cell Rate (ACR) value would be increased by the
amount (RIF*ACR). The ACR is not allowed to exceed the Peak
Cell Rate (PCR), in which case the ACR is set to PCR.

atmIfVptVpdTmAbrMaxCellPerRmCellThis attribute specifies the maximum number of cells an ABR
source may transmit for each forward Resource Management (RM)
cell. The count of the cells transmitted includes data cells, OAM
cells, backward RM cells, and the forward RM cell.
A value of 2 is not recommended although it is permitted according
to the ATM Forum standard. When this attribute is set to a value of
2, it is possible that only one forward and one backward RM cell
are repeatedly transmitted, and all data traffic is queued up
indefinitely.

atmIfVptVpdTmAbrMaxTimeBetweenRmCellsThis attribute specifies the TRM parameter for this connection.
TRM provides an lower bound on the time interval between forward
Resource Management (RM) cells for an ABR source. Since the last
forward RM cell was sent, if at least TRM time has elapsed since
and at least two other cells have been sent, then the next cell to be
transmitted would be a forward RM cell.
This attribute is ignored under all conditions where the operational
attribute abrConnectionType has the value erSwitch.

atmIfVptVpdTmAbrCutoffDecreaseFactorThis attribute specifies the Cutoff Decrease Factor (CDF) parameter
for this connection. When the value of this attribute is non-zero,
CDF is computed as the inverse of the value. For example, if the
value is 32, the value of CDF is 1/32. When the value of this
attribute is 0, CDF is also zero.
CDF controls the decrease in the Allowed Cell Rate (ACR)
associated with the CRM parameter, the limit of the number of
forward Resource Management (RM) cells which may be sent in
the absence of received backward RM cells. When this limit is
crossed, the ACR value would be decreased by the amount
(CDF*ACR). The ACR is not allowed to fall below the Minimum
Cell Rate (MCR), in which case the ACR is set to MCR.
The value of CRM is indicated by the forwardRmCellLimit
attribute.

atmIfVptVpdTmAbrAcrDecreaseTimeFactorThis attribute specifies the Allowed Cell Rate Decrease Time Factor
(ADTF) parameter for this connection.
ADTF is the maximum time interval permitted between sending
forward Resource Management (RM) cells before the Allowed Cell
Rate (ACR) is decreased to initialCellRate. In other words, if the
source does not transit a forward RM cell for the period specified by
adtf, it reduces its ACR to the value of its initialCellRate.

atmIfVptVpdTmAbrDgcraMaximumDelayThis attribute specifies an upper bound on the delay after which the
rate change induced by a backward Resource Management (RM)
cell departing from this connection point (in the backward
direction) is expected to be observed at this connection point (in the
forward direction).
This upper bound may be approximated as the sum of the round trip
fixed and propagation delays and the maximum queuing delays
between the ABR source and this interface.
The value of this attribute is used in policing an ABR connection
using the Dynamic General Cell Rate Algorithm (DGCRA). A
larger value for this attribute implies a more lenient policer. When
there is a reduction in the Allowed Cell Rate (ACR), the policer
waits for a correspondingly longer period of time before it enforces
at the new cell rate.

The value of this attribute is used in policing an ABR connection
using the Dynamic Generic Cell Rate Algorithm (DGCRA). A
larger value for this attribute implies a more lenient policer. When
the delay between two consecutive forward Resource Management
(RM) cells received at this interface corresponds to a value greater
than the value of this attribute, the policer begins to limit enforce
the incoming traffic at the initial cell rate (ICR) of the far end, as

atmIfVptVpdTmAtmServiceCategoryThis attribute specifies the ATM service category for both directions
of the connection.
The value derivedFromBBC may only be used if the SrcPvc
component is provisioned under this Vcc. Otherwise a specific
ATM service category must be specified.
If this attribute is set to derivedFromBBC, the Broadband Bearer
Capability (BBC) and bestEffort attributes are used to determine the
atmServiceCategory of this connection.
If this attribute is set to other than derivedFromBBC, the value of
this attribute is used to override the provisioned BBC Information
Element parameters. In those cases, the BBC attributes are not used.
The constantBitRate service category is intended for real time
applications, that is those requiring tightly constrained delay and
delay variation, as would be appropriate for voice and video
applications. The consistent availability of a fixed quantity of
bandwidth is considered appropriate for CBR service. Cells which
are delayed beyond the value specified by Cell Transfer Delay are
assumed to be of significantly reduced value to the application.
The rtVariableBitRate service category is intended for real time
applications, that is those requiring tightly constrained delay and
delay variation, as would be appropriate for voice and video
applications. Sources are expected to transmit at a rate which varies
with time. Equivalently, the source can be described as 'bursty'.
Cells which are delayed beyond the value specified by CTD are
assumed to be of significantly reduced value to the application. Real
time VBR service may support statistical multiplexing of real time
sources.
The nrtVariableBitRate service category is intended for non-real
time applications which have bursty traffic characteristics and which
can be characterized in terms of a PCR, SCR, and MBS. For those
cells which are transferred within the traffic contract, the application
expects a low cell loss ratio. For all connections, it expects a bound
on the mean cell transfer delay. Non-real time VBR service may
support statistical multiplexing of connections.
The availableBitRate service is an ATM layer service category for
which the limiting ATM layer transfer characteristics provided by
the network may change subsequent to connection establishment.
ABR service has a flow control mechanism which supports several
types of feedback to control the source rate in response to changing
ATM layer transfer characteristics. ABR service is not intended to
support real-time applications.
The unspecifiedBitRate service is intended for non-real time
applications; that is, those not requiring tightly constrained delay
and delay variation. UBR sources are expected to be bursty. UBR
service supports a high degree of statistical multiplexing among
sources. UBR service does not specify traffic related service
guarantees. No numerical commitments are made with respect to
the cell loss ratio experienced by a UBR connection, or as to the
cell transfer delay experienced by cells on the connection.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.114.9.2.2.100.1.42 |
atmIfVptVpdTmTrafficShapingThis attribute specifies whether this connection uses traffic shaping
when transmitting traffic to the ATM interface.
This attribute is ignored if the atmServiceCategory is
availableBitRate.
When sameAsCa is selected, traffic shaping for the connection is
based on the trafficShaping attribute of the connection's service
category component under the CA. If the service category has
trafficShaping set to enabled or inverseUpc, then traffic shaping is
enabled for the connection. Note that enabling traffic shaping may
have no effect under certain cases. These cases are listed in the
description of the trafficShaping operational attribute, which is
under the Vcc Tm, Vpc Tm, or Vpt Tm components.
When disabled is selected, traffic shaping for this connection is

atmIfVptVpdTmUnshapedTransmitQueueingThis attribute only applies when this connection is unshaped. This
attribute specifies the transmit queueing method for this connection
if it is unshaped. The two possible methods are per-VC queuing and
common queuing.
On ATM IP FPs, this attribute must be set to sameAsCa.
This attribute is ignored in the following situations:
- if the connection has trafficShaping enabled or inverseUpc, or
- if the atmServiceCategory is availableBitRate, or
- if the atmServiceCategory is constantBitRate and this is a CQC-
based ATM FP.
- for basic Vpts and standard Vpt Vccs
When this attribute is set to sameAsCa, the transmit queueing
method for the connection is based on the
unshapedTransmitQueueing attribute of the connection's service
category component under the CA.
When this attribute is set to common, transmit traffic on this
unshaped connection is destined for the common queue.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.114.9.2.2.100.1.60 |

fairnessWeight attribute under the CA service category component
for all but standard Vpt Vccs. For standard Vpt Vccs, the weight is
determined by the Vcc's service category, when the value is set to
sameAsCa.
When this attribute is set to a value from 1 to 4095, that value is
used for the fairness weight of this connection relative to other
connections. For all but standard Vpt Vccs, fairness weight
determines the proportion of transmit cell opportunities which are
allocated to this connection, compared to other connections in the
same service category. For standard Vpt Vccs, fairness weight
determines the proportion of transmit cell opportunities which are
allocated to this connection, compared to other connections
associated with the Vpt.
When the value is set to upToQueueLimit, the fairness weight is
limited only by the txQueueLimit.

atmIfVptVpdTmForceTaggingThis attribute specifies whether force tagging is enforced for this
connection for cells in the transmit direction.
On CQC-based ATM cards, and for Vpts, this attribute is not
applicable and is ignored.
When the value is set to sameAsCa, the force tagging functionality
is determined by the forceTagging attribute under the CA service
category component.
When the value is set to enabled, force tagging is enabled for cells
in the transmit direction on this connection. When this option is
selected, the CLP bit is set to 1 for all cells in the transmit direction.
Cells which are tagged are counted in the txCellClp attribute.
When the value is set to disabled, force tagging is disabled for cells
in the transmit direction on this connection. When this option is
selected, the CLP bit is unchanged for cells in the transmit
direction.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.114.9.2.2.100.1.62 |
atmIfVptVpdTmUsageParameterControlThis attribute specifies whether this connection enforces usage
parameter control when receiving traffic from the ATM interface.
When sameAsCa is selected, UPC for the connection is based on
the usageParameterControl attribute of the service category
component under the AtmIf CA. If the service category has UPC
enforced or monitored, then UPC is set to that value for the
connection.
When disabled is selected, UPC for this connection is disabled
regardless of the provisioning of the service category.
When enforced is selected, UPC for this connection is enforced
regardless of the provisioning of the service category.
ATM IP cards provide the ability to monitor UPC violations without
tagging or discarding. When monitored is selected, UPC is actively
checking conformance for the connection and counting the
violations, but is not discarding or tagging cells which do not
conform to the connection traffic contract.
If this is a connection of serviceCategory abr on an ATM IP card,
and the abrConnectionType is sourceDest, virtualSourceDest or
explicitRate, selecting enforced enables dynamic generic cell rate
algorithm (DGCRA) to discard violating cells. Selecting monitored
enables DGCRA to count violating cells.
Note that setting UPC to enforced or monitored may have no effect
under certain cases. These cases are listed in the description of the
usageParameterControl operational attribute, which is under the
Vcc, Vpc, and Vpt components.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.114.9.2.2.100.1.70 |
atmIfVptVpdTmBearerClassBbcThis attribute specifies the bearer capability. This attribute is only
used for SPVC and SPVP connections. It is one of the Broadband
Bearer Capability (BBC) attributes. The purpose of the BBC
information element is to indicate a requested broadband
connection-oriented bearer service to be provided by the network.
The value derivedFromServiceCategory specifies that the actual
value which is used for this connection is derived from the value of
the atmServiceCategory. Either, this attribute must be set to
derivedFromServiceCategory, or the atmServiceCategory attribute
must be set to derivedFromBBC, but not both.
Class a service is a connection-oriented, constant bit rate ATM
transport service. Class a service has end to end timing
requirements and may require stringent cell loss, cell delay and cell
delay variation performance.When a is set, the user is requesting
more than an ATM only service. The network may look at the AAL
to provide interworking based upon its contents.
Class c service is a connection-oriented, variable bit rate ATM
transport service. Class c service has no end-to-end timing
requirements. When c is set, the user is requesting more than an
ATM only service. The network interworking function may look at
the AAL and provide service based on it.
Class x service is a connection-oriented ATM transport service
where the AAL, trafficType (vbr or cbr) and timing requirements
are user defined (that is, transparent to the network).When x is set
the user is requesting an ATM only service from the network. In this
case, the network shall not process any higher layer protocol.
Class vp service is used to specify a transparent VP service. When
the value of this attribute is vp, the user is requesting an ATM only
service from the network. In this case, the network shall not process
any higher layer protocol. This service differs from class x service
in that with the class vp service both the VCI field (except or VCI
values 0, 3, 4, and 6 through 15) and Payload Type field are
transported transparently by the network. This attribute value is
only applicable to SPVP connections.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.114.9.2.2.100.1.71 |
atmIfVptVpdTmTransferCapabilityBbcThis attribute specifies the transfer capability for this connection.

0: NoIndication, NoIndication
1: NoIndication, yes
2: NoIndication, no
5: CBR, yes
8: VBR, NoIndication
9: VBR, yes
10: VBR, no
notApplicable specifies that the user does not want to specify the
transfer capability.
The CBR traffic type refers to traffic offered on services such as a
constant bit rate video service or a circuit emulation.
The VBR traffic type refers to traffic offered on services such as
packetized audio and video, or data.
The value no indication for traffic type is used if the user has not set
the traffic type; similarly for end-to-end timing.
The value yes for end-to-end timing indicates that end-to-end
timing is required.
The value no for end-to-end timing indicates that end-to-end timing
is not required.
The value derivedFromServiceCategory specifies that the actual
value which is used for this connection is derived from the value of
the atmServiceCategory. Either, this attribute must be set to
derivedFromServiceCategory, or the atmServiceCategory attribute
must be set to derivedFromBBC, but not both.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.114.9.2.2.100.1.72 |
atmIfVptVpdTmTxWredThresholdThis attribute determines at what percentage of the queue being at
the EPD threshold, WRED starts. When the value is set to 25%,
WRED starts as soon as the queue is 25% of the way to the EPD
threshold. When the value is set to 50%, WRED starts later, after
the queue is 50% of the way to the EPD threshold. When the value
is set to 75%, WRED starts only when the queue is 75% of the way
to the EPD threshold. The EPD threshold is 85% of the transmit
queue length.

atmIfVptVpdTmTxPacketWiseDiscardThis attribute specifies whether packet-wise discard functions are to
be enabled or disabled in the transmit data direction for this
connection. Packet-wise discard functions should only be requested
if this connection is transferring AAL5 frame traffic. This attribute
is not applicable for Vpts.
Packet-wise functions increase the 'goodput' of the link. The
transmit packet-wise functions are Early Packet Discard (EPD) and
Partial Packet Discard (PPD).
EPD allows the connection to discard an entire frame once the
transmit queue has reached the EPD threshold. EPD increases the
'goodput' of a link, since discarding an entire frame means that
some queue capacity is guarded for some other frame which is
already partially transmitted. All cells of the frame are discarded
from the Beginning of Message (BOM) cell up to and including the
End of Message (EOM) cell.
PPD allows the connection to discard the remainder of a cell-
forwarded AAL5 frame if one cell of this frame has been discarded.
All cells are discarded up to but not including the EOM cell. The
PPD function increases the 'goodput' of the link, since cells which
are only going to be discarded at the AAL5 reassembly point are
not transmitted.
On CQC-based ATM cards, the packet-wise discard functions are
PPD and EPD. PPD is available at VCC cell-transfer points. PPD is
not applicable at frame-cell conversion points, and is not applicable
for Vpcs. PPD is configured by this attribute. Packet-wise discard
should only be enabled for connections carrying AAL5
segmentation traffic. Setting the value to enabled for any other
traffic type may result in all traffic being discarded. On CQC-based
ATM FPs, EPD is automatically enabled at frame-to-cell conversion
points, independent of the setting of this attribute.
On ATM IP cards, packet-wise discard functions include EPD and
PPD. PPD and EPD apply to individual VCCs and VCCs within
VPCs at all connection points, including tandem VPC connections.
Both PPD and EPD are controlled by this attribute. This attribute
may safely be set to enabled for any connection (Vcc or Vpc) on
ATM IP FPs since they have the ability to automatically detect
AAL5-segmented traffic on a connection, and only enable packet-
wise discards if AAL5-segmented traffic is detected.
When this attribute is set to enabled, packet-wise discard functions
are applied to transmit traffic at this connection point. When this
attribute is set to disabled, packet-wise discard functions are not
applied to transmit traffic at this connection point.
At a SPVC origin on a PNNI interface, a value of enabled specifies
that frame discard is requested in the backward direction. When this
attribute is set to disabled, backward frame discard is not requested
in the SPVC call setup.
The transmit packet-wise discard functions that are active are
visible in the Vcc/Vpc Tm txPacketWiseDiscard operational
attribute.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.114.9.2.2.100.1.76 |
atmIfVptVpdTmTxWredModeThis attribute specifies the activation of weighted random early
detection (WRED) functionality. WRED is only available on ATM
IP FPs. On CQC-based ATM FPs, this attribute is ignored. If
txPacketWiseDiscard is set to disabled this attribute is ignored. This
attribute is not applicable for Vpts or Vpt Vccs.
WRED is applied in the transmit direction for this connection.
WRED function should be enabled only for connections which are
transferring TCP/IP traffic. WRED acts to prevent synchronization
of multiple TCP/IP sources by randomly discarding a small
percentage of frames when transmit queue congestion reaches the
designated level. W-RED may also be used to differentiate service
on VCC's by preferentially discarding one VCC before another.
Discards start at 0% of cells, when the queue is part-way to the
Early Packet Discard (EPD) threshold, and rise to 100% of cells
discarded at the EPD threshold. WRED discards all the cells in a
frame.
If this attribute is set to enabled, WRED is enabled for all
applications linked to the given Vcc. If it is set to perFlow, each
TCP application has individual control over whether to enable or
disable WRED
If txPacketWiseDiscard is set to disabled, or if this attribute is set to
disabled, WRED functionality is disabled.
If WRED is active, it is visible in the Vcc/Vpc Tm
txPacketWiseDiscard operational attribute.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.114.9.2.2.100.1.77 |
atmIfVptVpdTmRxPacketWiseDiscardThis attribute specifies whether packet-wise discard functions are to
be enabled or disabled in the receive data direction for this
connection. Packet-wise discard functions should only be requested
if this connection is transferring AAL5 frame traffic. This attribute
is not applicable for Vpts.
Packet-wise functions increase the 'goodput' of the link. The
receive packet-wise function is Partial Packet Discard (PPD).
PPD allows the connection to discard the remainder of a cell-
forwarded AAL5 frame if one cell of this frame has been discarded,
for example due to UPC. All cells are discarded up to but not
including the EOM cell. The PPD function increases the 'goodput'
of the link, since cells which are only going to be discarded at the
AAL5 reassembly point are not transmitted.
PPD is available at all VCC connection points where UPC may be
activated. PPD is not applicable for Vpcs.
On CQC-based ATM FPs, packet-wise discards should only be
enabled for connections carrying AAL5 segmentation traffic.
Setting the value to enabled for any other traffic type may result in
traffic being discarded.
On ATM IP cards, this attribute may safely be set to enabled for any
connection (Vcc or Vpc) since they have the ability to automatically
detect AAL5-segmented traffic on a connection, and only enables
packet-wise discards if AAL5-segmented traffic is detected.
When this attribute is set to enabled, packet-wise discard functions
are applied to receive traffic at this connection point. When this
attribute is set to disabled, packet-wise discard functions are not
applied to receive traffic at this connection point.
At a SPVC origin on a PNNI interface, a value of enabled specifies
that frame discard is requested in the forward direction. When this
attribute is set to disabled, forward frame discard is not requested in
the SPVC call setup.
The receive packet-wise discard functions that are active are visible
in the Vcc/Vpc Tm rxPacketWiseDiscard operational attribute.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.114.9.2.2.100.1.78 |
atmIfVptVpdTmAbrConnectionTypeThis attribute specifies the type of ABR behavior which is to be
enforced at this connection. This attribute is only applicable if the
atmServiceCategory attribute is availableBitRate. If the
atmServicecategory attribute is not availableBitRate, this attribute
value is ignored.
The actual ABR functionality which is in effect is visible in the
Vcc/Vpc/Vpt Tm abrConnectionType operational attribute.
For CQC-based ATM cards, the only allowable values are
sameAsCa, nonAbrInterworking or abrSwitch. If abrSwitch is
selected, the CQC implements EFCI marking behavior.
sameAsCa is used to request the default behavior as specified in the
CA Abr component for this Vcc. Otherwise, this attribute overrides
the default behavior.
virtualSourceDest is used to request that this connection point
function as a virtual source/virtual destination. VS/VD functionality
is only supported on ATM IP FPs.
sourceDest requires that this connection point function as a S/D for
RM cells. S/D mode is automatically invoked at this connection
point either if this is a connection end point, or if the next hop
connection point is configured as nonAbrInterworking.
nonAbrInterworking is used to request that this connection point
function as an interworking between ABR and non-ABR service
categories. This means that there are no RM cells on the link side of
this connection, and that the next hop connection point is
performing as an ABR sourceDest.
abrSwitch is used to request ABR switch behavior for this
connection point. The ABR switch behavior is first, to confirm to
virtualSourceDest or nonAbrInterworking setting on the next hop,
and otherwise to implement ABR ER switch behavior. For CQC-
based FPs, ABR switch behavior is implemented as EFCI marking.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.114.9.2.2.100.1.90 |
atmIfVptVpdTmTxTdpTableThis attribute is a vector of five traffic parameters whose meanings
are defined by the txTrafficDescType attribute.
The values of peak cell rate (PCR), sustained cell rate (SCR),
Minimum Cell Rate (MCR) and requested shaping rate are
expressed in cell/s. Maximum burst size (MBS) is expressed in
cells. CDVT is expressed in microseconds. The values of PCR,
SCR, MCR, MBS and CDVT are used for connection admission
control (CAC). The value of CDVT is only used for connections
where the atmServiceCategory is constantBitRate. For all other
values of atmServiceCategory, CDVT is ignored. The values of
PCR, SCR, MCR and requested shaping rate are used to determine
the actual shaping rate where traffic shaping is enabled.
When txTrafficDescType is 1 or 2, all of the parameters must be set
to zero.
When txTrafficDescType is 3, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic; parameter 4 represents the CDVT; and
parameter 5 represents the requested shaping rate. A non-zero value
in parameter 5 overrides any value in parameter 1. This result is
used as the PCR. Parameter 1 must be non-zero. Parameters 2 and 3
must be zero.
When txTrafficDescType is 4, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic with cell discard; parameter 2
represents the PCR for CLP equal to 0 traffic; parameter 4
represents the CDVT; and parameter 5 represents the requested
shaping rate. A non-zero value in parameter 5 overrides any value in
parameter 1. This result is used as the PCR. Parameter 1 must be
greater than or equal to parameter 2. Parameters 1 and 2 must be
non-zero. Parameter 3 must be zero.
When txTrafficDescType is 5, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic with cell tagging; parameter 2
represents the PCR for CLP equal to 0 traffic; parameter 4
represents the CDVT; and parameter 5 represents the requested
shaping rate. A non-zero value in parameter 5 overrides any value in
parameter 1. This result is used as the PCR. Parameter 1 must be
greater than or equal to parameter 2. Parameters 1 and 2 must be
non-zero. Parameter 3 must be zero.
When txTrafficDescType is 6, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic; parameter 2 represents the SCR for
CLP equal to 0 and 1 traffic; parameter 3 represents the MBS for
CLP equal to 0 and 1 traffic; parameter 4 represents the CDVT; and
parameter 5 represents the requested shaping rate. A non-zero value
in parameter 5 overrides any value in parameter 1. This result is
used as the PCR. Parameters 1, 2 and 3 must be non-zero.
Parameter 1 must be greater than or equal to parameter 2. Parameter
5, must either be zero (unused) or greater than or equal to parameter
2.
When txTrafficDescType is 7, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic; parameter 2 represents the SCR for
CLP equal to 0 with cell discard; parameter 3 represents the MBS
for CLP equal to 0 traffic; parameter 4 represents the CDVT; and
parameter 5 represents the requested shaping rate. A non-zero value
in parameter 5 overrides any value in parameter 1. This result is
used as the PCR. Parameters 1, 2 and 3 must be non-zero.
Parameter 1 must be greater than or equal to parameter 2. Parameter
5, must either be zero (unused) or greater than or equal to parameter
2.
When txTrafficDescType is 8, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic; parameter 2 represents the SCR for
CLP equal to 0 traffic with cell tagging; parameter 3 represents the
MBS for CLP equal to 0 traffic; parameter 4 represents the CDVT;
and parameter 5 represents the requested shaping rate. A non-zero
value in parameter 5 overrides any value in parameter 1. This result
is used as the PCR. Parameters 1, 2 and 3 must be non-zero.
Parameter 1 must be greater than or equal to parameter 2. Parameter
5, must either be zero (unused) or greater than or equal to parameter
2.
When txTrafficDescType is 9, parameter 1 represents the PCR;
parameter 2 represents the CDVT; parameter 3 represents the MCR;
parameter 4 and parameter 5 represent are not used and must be
zero. Parameter 1 must be non-zero and must be greater than or
equal to parameter 3. Parameter 3 may be optionally zero.
Whenever it is valid for PCR to be specified, parameter 5 may also
be used to specify a requested shaping rate. A non-zero value in
parameter 5 overrides the value in parameter 1 and is used as the
peak cell rate in calculations of CAC and shaping rate. When the
atmServiceCategory is availableBitRate (ABR), the shaping rate is
dynamically chosen, based on the ABR flow control mechanism, as
a value between the MCR and the PCR or the requested shaping
rate if applicable.
For txTrafficDescType 3, 4 and 5, the transmit traffic is shaped at
the next available shaping rate less than the PCR.
For txTrafficDescType 6, 7 and 8 if linear traffic shaping is selected,
the transmit traffic is shaped at the highest available rate which is
between PCR and SCR. However, if there is no available shaping
rate between PCR and SCR, traffic is shaped at the next rate above
the PCR.
For txTrafficDescType 6, 7 and 8 if inverse-UPC traffic shaping is
selected, the transmit traffic is shaped at a variable rate which
conforms to the PCR, SCR and MBS of the connection traffic
descriptor. Inverse-UPC traffic shaping is available only on ATM IP

When rxTrafficDescType is any value from 3 through 8, parameter
4 represents the CDVT.
If the value of CDVT either in parameter 2 or in parameter 4 is zero,
the CDVT is taken from the CA defaults for the particular
atmServiceCategory of this connection.
On a CQC-based ATM card, when rxTrafficDescriptorType is 3
through 8, there are certain extreme combinations of
rxTrafficDescParm which are outside the capabilities of the UPC
hardware. The check prov command detects such cases and
generates an error message. If this happens, adjust the parameters
until they fall within the supported limits.
To calculate the limits, use the following formulae:
I1 = 1 000 000 000 / PCR
L1 = CDVT * 1000
I2 = 1,000,000,000 / SCR
L2 = CDVT + (MBS - 1) * (I2 - I1)
I1 and I2 must be less than or equal to 335,523,840. I1 + L1 must
be less than or equal to 1,342,156,800. I2 + L2 must be less than or
equal to 1,342,156,800. Note that I2 and L2 only apply when the
rxTrafficDescriptorType is 6 through 8.
If the values of I1, L1, I2 or L2 are closer to the limits described
above, a further restriction applies. Specifically, if either:
I1 > 41,940,480 or
I2 > 41,940,480 or
I1 + L1 > 167,769,600 or
I2 + L2 > 167,769,600
then both I1 and I2 must be greater than 20,480.
Parameter 5 of the rxTrafficDescParm is always unused.
If the rxTrafficDescType is sameAsTx, the values provisioned in
this attribute are ignored. The traffic parameters for the receive

atmIfVptVpdAtmServiceCategoryThis attribute is migrated to the AtmTmProv group.
This attribute specifies the ATM service category for both directions
of the connection.
The value derivedFromBBC may only be used if the SrcPvc
component is provisioned under this Vcc.Otherwise a specific ATM
service category must be specified.
If this attribute is set to derivedFromBBC, the Broadband Bearer
Capability (BBC) and bestEffort attributes are used to determine the
atmServiceCategory of this connection.
If this attribute is set to other than derivedFromBBC, the value of
this attribute is used to override the provisioned BBC Information
Element parameters. In those cases, the BBC attributes are not used.
The constantBitRate service category is intended for real time
applications, that is those requiring tightly constrained delay and
delay variation, as would be appropriate for voice and video
applications. The consistent availability of a fixed quantity of
bandwidth is considered appropriate for CBR service. Cells which
are delayed beyond the value specified by Cell Transfer Delay are
assumed to be of significantly reduce value to the application.
The rtVariableBitRate service category is intended for real time
applications, that is those requiring tightly constrained delay and
delay variation, as would be appropriate for voice and video
applications. Sources are expected to transmit at a rate which varies
with time. Equivalently, the source can be described as 'bursty'.
Cells which are delayed beyond the value specified by CTD are
assumed to be of significantly reduced value to the application. Real
time VBR service may support statistical multiplexing of real time
sources.
The nrtVariableBitRate service category is intended for non-real
time applications which have bursty traffic characteristics and which
can be characterized in terms of a PCR, SCR, and MBS. For those
cells which are transferred within the traffic contract, the application
expects a low cell loss ratio. For all connections, it expects a bound
on the mean cell transfer delay. Non-real time VBR service may
support statistical multiplexing of connections.
The unspecifiedBitRate service is intended for non-real time
applications; that is, those not requiring tightly constrained delay
and delay variation. UBR sources are expected to be bursty. UBR
service supports a high degree of statistical multiplexing among
sources. UBR service does not specify traffic related service
guarantees. No numerical commitments are made with respect to
the cell loss ratio experienced by a UBR connection, or as to the
cell transfer delay experienced by cells on the connection.rwobsolete Enumeration .1.3.6.1.4.1.3764.1.1.30.114.9.2.110.1.42 |
atmIfVptVpdTrafficShapingThis attribute is migrated to the AtmTmProv group.
This attribute specifies whether this connection uses traffic shaping

connection's parent AtmIf componentif the ATM interface has
traffic shaping enabled, then traffic shaping is enabled for the
connection. Note that enabling traffic shaping may have no effect
under certain cases. These cases are listed in the description of the

When sameAsInterface is selected, UPC for the connection is
based on the usageParameterControl attribute of the connection's
parent AtmIf componentif the ATM interface has UPC enabled,
then UPC is enabled for the connection. Note that enabling UPC
may have no effect under certain cases. These cases are listed in the
description of the usageParameterControl operational attribute,
which is under the Vcc and Vpc components.

atmIfVptVpdBearerClassBbcThis attribute is migrated to the AtmTmProv group.
This attribute specifies the bearer capability. This attribute is only
used for SPVC and SPVP connections. It is one of the Broadband
Bearer Capability (BBC) attributes. The purpose of the BBC
information element is to indicate a requested broadband
connection-oriented bearer service to be provided by the network.
The value derivedFromServiceCategory specifies that the actual
value which is used for this connection is derived from the value of
the atmServiceCategory. Either, this attribute must be set to
derivedFromServiceCategory, or the atmServiceCategory attribute
must be set to derivedFromBBC, but not both.
Class a service is a connection-oriented, constant bit rate ATM
transport service. Class a service has end to end timing
requirements and may require stringent cell loss, cell delay and cell
delay variation performance.When a is set, the user is requesting
more than an ATM only service. The network may look at the AAL
to provide interworking based upon its contents.
Class c service is a connection-oriented, variable bit rate ATM
transport service. Class c service has no end-to-end timing
requirements. When c is set, the user is requesting more than an
ATM only service. The network interworking function may look at
the AAL and provide service based on it.
Class x service is a connection-oriented ATM transport service
where the AAL, trafficType (vbr or cbr) and timing requirements
are user defined (that is, transparent to the network).When x is set
the user is requesting an ATM only service from the network.
Class vp service is used to specify a transparent VP service. When
the value of this attribute is vp, the user is requesting an ATM only
service from the network. In this case, the network shall not process
any higher layer protocol. This service differs from class x service
in that with the class vp service both the VCI field (except or VCI
values 0, 3, 4, and 6 through 15) and Payload Type field are
transported transparently by the network. This attribute value is
only applicable to SPVP connections.rwobsolete Enumeration .1.3.6.1.4.1.3764.1.1.30.114.9.2.110.1.71 |
atmIfVptVpdTransferCapabilityBbcThis attribute is migrated to the AtmTmProv group.

0: NoIndication, NoIndication
1: NoIndication, yes
2: NoIndication, no
5: CBR, yes
8: VBR, NoIndication
9: VBR, yes
10: VBR, no
NotApplicable specifies that the user does not want to specify the
transfer capability.
The CBR traffic type refers to traffic offered on services such as a
constant bit rate video service or a circuit emulation.
The VBR traffic type refers to traffic offered on services such as
packetized audio and video, or data.
The value no indication for traffic type is used if the user has not set
the traffic type; similarly for end-to-end timing.
The value yes for end-to-end timing indicates that end-to-end
timing is required.
The value no for end-to-end timing indicates that end-to-end timing
is not required.
The value derivedFromServiceCategory specifies that the actual

atmIfVptVpdFwdFrameDiscardThis attribute specifies the activation of frame discard functionality
in the forward data direction, at relay points, for this connection. It
applies to each hop of the connection. Frame discard functions
should not be requested if this connection is not transferring frame
(AAL5) traffic. Setting the value to indicated for any other traffic
type results in all traffic being discarded.
If this connection point is a permanent (provisioned) VCC mid-
point, this attribute specifies whether the Partial Packet
Discard (PPD) function is to be enabled or disabled in the transmit
direction at this connecting point. The PPD function allows the
connecting point to discard the remainder of a cell-forwarded AAL5
frame if one cell of this frame has been discarded. The PPD
function increases the 'goodput' of the link, since cells which are
only going to be discarded by the AAL5 reassembly are not
transmitted.
At a permanent VCC connecting point which is not a connection
endpoint, when this attribute is set to indicated, the PPD function is
applied to transmit traffic at this connecting point. It should not be
indicated for connections whose end points are not performing
AAL5 segmentation and reassembly. When this attribute is set to
notIndicated, the PPD feature is not applied to transmit traffic at
this connecting point.
At a SPVC origin on a PNNI interface, a value of indicated
specifies that frame discard is requested in the forward direction.
The frame discard function for SPVCs consists of PPD at the SPVC
origin and at all intermediate connecting points. When this attribute
is set to notIndicated, forward frame discard is not requested in the
SPVC call setup. Thus PPD is not enabled at the SPVC origin nor at
any intermediate connecting point.
At all points along a VPC, this setting is ignored.
At a permanent VCC connection endpoint, this value is ignored. If
AAL5 segmentation and reassembly has been requested, PPD and
Early Packet Discard (EPD) are automatically enabled.

atmIfVptVpdBwdFrameDiscardThis attribute specifies the activation of frame discard functionality
in the backward data direction, at relay points, for this connection.
It applies to each hop of the connection. Frame discard functions
should not be requested if this connection is not transferring frame
(AAL5) traffic. Setting the value to indicated for any other traffic
type results in all traffic being discarded.
If this connection point is a permanent (provisioned) VCC mid-
point, this attribute specifies whether the Partial Packet Discard
(PPD) function is to be enabled or disabled in the receive direction
at this connecting point. The PPD function allows the connecting
point to discard the remainder of a cell-forwarded AAL5 frame if
one cell of this frame has been discarded. The PPD function
increases the 'goodput' of the link, since cells which are only going
to be discarded by the AAL5 reassembly are not received.
At a permanent VCC connecting point which is not a connection
endpoint, when this attribute is set to indicated, the PPD function is
applied to receive traffic at this connecting point. It should not be
indicated for connections whose end points are not performing
AAL5 segmentation and reassembly. When this attribute is set to
notIndicated, the PPD feature is not applied to receive traffic at this
connecting point.
At a SPVC origin on a PNNI interface, a value of indicated
specifies that frame discard is requested in the backward direction.
The frame discard function for SPVCs consists of PPD at the SPVC
origin and at all intermediate connecting points. When this attribute
is set to notIndicated, backwards frame discard is not requested in
the SPVC call setup. Thus PPD is not enabled at the SPVC origin
nor at any intermediate connecting point.
At all points along a VPC, this setting is ignored.
At a permanent VCC connection endpoint, this value is ignored. If
AAL5 segmentation and reassembly has been requested, PPD and

for the VPT, at the VC level. VCs within the VP are treated like
independent VCC connections, and thus, are scheduled the same as
other VCs under the AtmIf, with no scheduling done for the VP
itself.
A value of standard configures two levels of TM for the VPT, one
level for VP TM and one level for VC level TM. VCs within the VP
use weighted fair queueing (standard VPT VCC scheduling) to
schedule VCs within the VPT, with VCs differentiated as either
real-time (CBR, rt-VBR) or non-real-time (nrt-VBR, UBR)
connections. The VP itself has a full range of emission scheduling
and service category differentiation available between itself and the
other connections under the AtmIf.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.114.9.2.112.1.10 |
atmIfVptVpdTxTdpTableThis attribute is migrated to the AtmTmProv group.
This attribute is a vector of five traffic parameters whose meanings
are defined by the txTrafficDescType attribute. The values of peak
cell rate (PCR), sustained cell rate (SCR) and requested shaping rate
are expressed in cell/s. Maximum burst size (MBS) is expressed in
cells. CDVT is expressed in microseconds. The values of PCR,
SCR, MBS and CDVT are used for connection admission control
(CAC). The value of CDVT is only used for connections where the
atmServiceCategory is constantBitRate. For all other values of
atmServiceCategory, CDVT is ignored. The values of PCR, SCR
and requested shaping rate are used to determine the actual shaping
rate where traffic shaping is enabled.
When txTrafficDescType is 1 or 2, all of the parameters must be set
to zero.
When txTrafficDescType is 3, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic; parameter 4 represents the CDVT; and
parameter 5 represents the requested shaping rate. A non-zero value
in parameter 5 overrides any value in parameter 1. This result is
used as the PCR. Parameter 1 must be non-zero. Parameters 2 and 3
must be zero.
When txTrafficDescType is 4, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic with cell discard; parameter 2
represents the PCR for CLP equal to 0 traffic; parameter 4
represents the CDVT; and parameter 5 represents the requested
shaping rate. A non-zero value in parameter 5 overrides any value in
parameter 1. This result is used as the PCR. Parameter 1 must be
greater than or equal to parameter 2. Parameters 1 and 2 must be
non-zero. Parameter 3 must be zero.
When txTrafficDescType is 5, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic with cell tagging; parameter 2
represents the PCR for CLP equal to 0 traffic; parameter 4
represents the CDVT; and parameter 5 represents the requested
shaping rate. A non-zero value in parameter 5 overrides any value in
parameter 1. This result is used as the PCR. Parameter 1 must be
greater than or equal to parameter 2. Parameters 1 and 2 must be
non-zero. Parameter 3 must be zero.
When txTrafficDescType is 6, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic; parameter 2 represents the SCR for
CLP equal to 0 and 1 traffic; parameter 3 represents the MBS for
CLP equal to 0 and 1 traffic; parameter 4 represents the CDVT; and
parameter 5 represents the requested shaping rate. A non-zero value
in parameter 5 overrides any value in parameter 1. This result is
used as the PCR. Parameters 1, 2 and 3 must be non-zero.
Parameter 1 must be greater than or equal to parameter 2. Parameter
5, must either be zero (unused) or greater than or equal to parameter
2.
When txTrafficDescType is 7, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic; parameter 2 represents the SCR for
CLP equal to 0 with cell discard; parameter 3 represents the MBS
for CLP equal to 0 traffic; parameter 4 represents the CDVT; and
parameter 5 represents the requested shaping rate. A non-zero value
in parameter 5 overrides any value in parameter 1. This result is
used as the PCR. Parameters 1, 2 and 3 must be non-zero.
Parameter 1 must be greater than or equal to parameter 2. Parameter
5, must either be zero (unused) or greater than or equal to parameter
2.
When txTrafficDescType is 8, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic; parameter 2 represents the SCR for
CLP equal to 0 traffic with cell tagging; parameter 3 represents the
MBS for CLP equal to 0 traffic; parameter 4 represents the CDVT;
and parameter 5 represents the requested shaping rate. A non-zero
value in parameter 5 overrides any value in parameter 1. This result
is used as the PCR. Parameters 1, 2 and 3 must be non-zero.
Parameter 1 must be greater than or equal to parameter 2. Parameter
5, must either be zero (unused) or greater than or equal to parameter
2.
Whenever it is valid for PCR to be specified, parameter 5 may also
be used to specify a requested shaping rate. A non-zero value in
parameter 5 overrides the value in parameter 1 and is used as the
peak cell rate in calculations of CAC and shaping rate.
For txTrafficDescType 3, 4 and 5, the transmit traffic is shaped at
the next rate less than the PCR.
For txTrafficDescType 6, 7 and 8, the transmit traffic is shaped at
the highest available rate which is between PCR and SCR.
However, if there is no available shaping rate between PCR and
SCR, traffic is shaped at the next rate above the PCR.obsolete SEQUENCE OF AtmIfVptVpdTxTdpEntry .1.3.6.1.4.1.3764.1.1.30.114.9.2.297 |

atmIfVptVpdRxTdpTableThis attribute is migrated to the AtmTmProv group.
This attribute is a vector of four traffic parameters whose meanings
are defined by the rxTrafficDescType attribute. The values of peak
cell rate (PCR) and sustained cell rate (SCR) are expressed in
cell/s. Maximum burst size (MBS) is expressed in cells. The value
of CDVT is expressed in microseconds. The values of PCR, SCR,
MBS and CDVT are used for usage parameter control (UPC).
When rxTrafficDescType is 1 or 2, all of the parameters must be set
to zero (unused).
When rxTrafficDescType is 3, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic. Parameter 1 must be non-zero.
Parameters 2 and 3 must be set to zero (unused).
When rxTrafficDescType is 4, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic; parameter 2 represents the PCR for
CLP equal to 0 traffic with cell discard. Parameters 1 and 2 must be
non-zero. Parameter 3 must be set to zero (unused). Parameter 1
must be greater than or equal to parameter 2.
When rxTrafficDescType is 5, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic; parameter 2 represents the PCR for
CLP equal to 0 traffic with cell tagging. Parameters 1 and 2 must be
non-zero. Parameter 3 must be set to zero (unused). Parameter 1
must be greater than or equal to parameter 2.
When rxTrafficDescType is a 6, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic; parameter 2 represents the SCR for
CLP equal to 0 and 1 traffic; parameter 3 represents the MBS for
CLP equal to 0 and 1 traffic. Parameters 1, 2 and 3 must be non-
zero. Parameter 1 must be greater than or equal to Parameter 2.
When rxTrafficDescType is 7, parameter 1 represents the PCR for

CLP equal to 0 traffic with cell discard; parameter 3 represents the
MBS for CLP equal to 0 traffic. Parameters 1, 2 and 3 must be non-
zero. Parameter 1 must be greater than or equal to parameter 2.
When rxTrafficDescType is 8, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic; parameter 2 represents the SCR for
CLP equal to 0 traffic with cell tagging; parameter 3 represents the
MBS for CLP equal to 0 traffic. Parameter 1, 2 and 3 must be non-
zero. Parameter 1 must be greater than or equal to parameter 2.
When rxTrafficDescType is any value from 3 through 8, parameter
4 represents the CDVT. If this value is zero, the CDVT is taken
from the ConnectionAdministrator defaults for the particular
atmServiceCategory of this connection.
When rxTrafficDescriptorType is 3 through 8, there are certain
extreme combinations of rxTrafficDescParm which are outside the
capabilities of the UPC hardware. The check prov command detects
such cases and generates an error message. If this happens, adjust
the parameters until they fall within the supported limits.
To calculate the limits, use the following formulae:
I1 = 1 000 000 000 / PCR
L1 = CDVT * 1000
I2 = 1 000 000 000 / SCR
L2 = CDVT + (MBS - 1) * (I2 - I1)
I1 and I2 must be less than or equal to 335 523 840. I1 + L1 must
be less than or equal to 1 342 156 800. I2 + L2 must be less than or
equal to 1 342 156 800. Note that I2 and L2 only apply when the
rxTrafficDescriptorType is 6 through 8.
If the values of I1, L1, I2 or L2 are closer to the limits described
above, a further restriction applies. Specifically, if either:
I1 > 41 940 480 or
I2 > 41 940 480 or
I1 + L1 > 167 769 600 or
I2 + L2 > 167 769 600
then both I1 and I2 must be greater than 20 480.
Parameter 5 of the rxTrafficDescParm is always unused.
If the rxTrafficDescType is sameAsTx, the values in this attribute
are taken from the txTrafficDescParm.obsolete SEQUENCE OF AtmIfVptVpdRxTdpEntry .1.3.6.1.4.1.3764.1.1.30.114.9.2.298 |

atmIfVptCACbrPoolThis attribute specifies the bandwidth pool which is to be used to
support the constant bit rate (CBR) service category. The percentage
of Vpt bandwidth capacity reserved for the given bandwidth pool is
the maximum bandwidth that can be allocated to CBR traffic. The
percentage allocated to each bandwidth pool can be provisioned

atmIfVptCACbrCdvtThis attribute specifies the default cell delay variation tolerance
(CDVT) for connections of the CBR service category. An override
to this default may be specified for a provisioned connection under
the Vcd Tm or Vpd Tm component.
This attribute is used by the CAC function to compute the
equivalent cell rate (ECR) required by a given CBR connection. The
larger the value of CDVT, the larger is its ECR.
If Usage Parameter Control (UPC) is enabled for a connection,
CDVT is used by the UPC function on the ingress to decide whether
a cell is conforming or non-conforming based on the connection's
traffic descriptor type. The larger the CDVT value, the more tolerant
is the UPC of bandwidth usage beyond the traffic contract.rw Unsigned32 .1.3.6.1.4.1.3764.1.1.30.114.9.5.2.100.1.20 |
atmIfVptCACbrCdvThis attribute specifies the peak-to-peak cell delay variation (CDV)
which is contributed to connections associated with this Vpt for
CBR traffic.
The CDV is a measure of the delay jitter introduced mostly by
traffic buffering and cell scheduling.
The value of this attribute is used by PNNI in the Resource
Availability Information Group (RAIG) topology updates and route
selection. It is also used by CAC at connection set-up time to
determine whether this Vpt can meet the ATM connection's CDV
requirement. If so, the value of this attribute is added to the

atmIfVptCACbrMaxCtdThis attribute specifies the maximum cell transfer delay (MaxCTD)
which is applied to all connections associated with this Vpt for CBR
traffic.
MaxCTD is the sum of the fixed delay and the CDV. The
components of the fixed delay include propagation delay through
the physical media, delays induced by the transmission system, and
fixed components of switch processing delay.

atmIfVptCACbrCellLossRatioThis attribute specifies the tolerable cell loss ratio (CLR) for CBR
traffic. The number is the negative logarithm (base 10) of the CLR.
For example, if the target CLR = 1E-10 then Cbr cellLossRatio =
10. This number must be the same as the RtVbr cellLossRatio since
CBR and rt-VBR traffic have the same discard priority. The Cbr
cellLossRatio is used by the Connection Admission Control (CAC)
algorithm to compute the required (equivalent) cell rate for CBR
connections.
There is a trade-off between the service category CLR and the
achievable Vpt bandwidth utilization. To guarantee an excellent
service category, the CLR should be as small as possible (e.g., 1E-
10). However, a smaller CLR results in a larger equivalent cell rate
for a given connection and hence a lower Vpt bandwidth utilization.
Setting this attribute to 0 means that a CLR of 1 can be tolerated. In
this case, no bandwidth is reserved for CBR connections, and CAC
is effectively turned off. All CBR connections are admitted.rw Unsigned32 .1.3.6.1.4.1.3764.1.1.30.114.9.5.2.100.1.50 |

atmIfVptCARtVbrCellLossRatioThis attribute specifies the tolerable cell loss ratio (CLR) for rt-
VBR traffic. The number is the negative logarithm (base 10) of the
CLR. For example, if the target CLR = 1E-10 then RtVbr
cellLossRatio = 10. This number must be the same as the Cbr
cellLossRatio since CBR and rt-VBR traffic have the same discard
priority. The RtVbr cellLossRatio is used by the Connection
Admission Control (CAC) algorithm to compute the required
(equivalent) cell rate for rt-VBR connections. This number must be
less than or equal to the NrtVbr cellLossRatio, since rt-VBR traffic
has a higher discard priority.
There is a trade-off between the service category CLR and the
achievable Vpt bandwidth utilization. To guarantee an excellent
service category, the CLR should be as small as possible (e.g., 1E-
10). However, a smaller CLR results in a larger equivalent cell rate

atmIfVptCANrtVbrPoolThis attribute specifies the bandwidth pool which is to be used to
support the non-real time variable bit rate (nrt-VBR) service
category. The percentage of Vpt bandwidth capacity reserved for the

allocated to nrt-VBR traffic. The percentage allocated to each

attribute under the CA.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.114.9.5.4.100.1.1 |
atmIfVptCANrtVbrCellLossRatioThis attribute specifies the tolerable cell loss ratio (CLR) for nrt-
VBR traffic. The number is the negative logarithm (base 10) of the
CLR. In other words if the target CLR = 1E-10 then NrtVbr
cellLossRatio = 10. This number must be greater than or equal to
RtVbr cellLossRatio since rt-VBR traffic has a higher discard
priority. The NrtVbr cellLossRatio is used by the Connection
Admission Control (CAC) algorithm to compute the required
(equivalent) cell rate for nrt-VBR connections.
There is a trade-off between the service category CLR and the
achievable Vpt bandwidth utilization. To guarantee an excellent
service category, the CLR should be as small as possible (e.g., 1E-
10). However, a smaller CLR results in a larger equivalent cell rate
for a given connection and hence a lower Vpt bandwidth utilization.
Setting this attribute to 0 means that a CLR of 1 can be tolerated. In
this case, no bandwidth is reserved for nrt-VBR connections, and
CAC is effectively turned off. All nrt-VBR connections are

atmIfVptTmAbrInitialCellRateThis attribute is applicable and is displayed only for connections for
which the operational Tm abrConnectionType is displayed as
sourceDest or virtualSourceDest.
This attribute indicates the Initial Cell Rate (ICR) parameter for this
connection. ICR is the rate at which a source should send initially
and after an idle period.
For nailed-up connections, this attribute is determined by the
provisioned value of the initialCellRate attribute. For signalled
connections, it is indicated in the ABR Setup Parameters
Information Element.
The ICR for a connection is a value between the MCR and the PCR.
Furthermore, ICR has an upper bound determined by the
transientBufferExposure divided by fixedRoundTripTime.ro Unsigned32 .1.3.6.1.4.1.3764.1.1.30.114.9.9.2.110.1.10 |
atmIfVptTmAbrTransientBufferExposureThis attribute is applicable and is displayed only for connections for
which the operational Tm abrConnectionType is displayed as
sourceDest or virtualSourceDest.
This attribute indicates the Transient Buffer Exposure (TBE) for
this connection. TBE is the negotiated number of cells that the
network would like to limit the resource to send during start-up
periods, before the first Resource Management (RM) cell returns.
For nailed-up connections, this attribute is determined by the
provisioned value of the transientBufferExposure attribute. For
signalled connections, it is indicated in the ABR Setup Parameters

atmIfVptTmAbrFixedRoundTripTimeThis attribute is applicable and is displayed only for connections for
which the operational Tm abrConnectionType is displayed as
sourceDest or virtualSourceDest.
This attribute indicates the Fixed Round-Trip Time (FRTT)
parameter for this connection. FRTT is the sum of the fixed and
propagation delays from the source to a destination and back.
For nailed-up connections, this attribute is determined by the
provisioned value of the fixedRoundTripTime attribute. For
signalled connections, it is indicated in the ABR Setup Parameters

atmIfVptTmAbrRateDecreaseFactorThis attribute is applicable and is displayed only for connections for
which the operational Tm abrConnectionType is displayed as
sourceDest or virtualSourceDest.
This attribute indicates the Rate Decrease Factor (RDF) for this
connection. The RDF value is computed by using the operational
value of this attribute, n, as 2 to the inverse power n. For example, if
the value of this attribute is 8, RDF is 2E-8 = 1/256.
RDF controls the amount by which the cell transmission rate may
decrease upon receipt of a backward Resource Management (RM)
cell. For example, if a backward RM cell is received with the
Congestion Indication (CI) field set to 1, the Allowed Cell Rate
(ACR) value would be reduced by the amount (RDF*ACR). The
ACR is not allowed to fall below the Minimum Cell Rate (MCR), in
which case the ACR is set to MCR.
For nailed-up connections, this attribute is determined by the
provisioned value of the rateDecreaseFactor attribute. For signalled
connections, it is indicated in the ABR Setup Parameters

atmIfVptTmAbrRateIncreaseFactorThis attribute is applicable and is displayed only for connections for
which the operational Tm abrConnectionType is displayed as
sourceDest or virtualSourceDest.
This attribute indicates the Rate Increase Factor (RIF) for this
connection. The RIF value is computed by using the operational
value of this attribute, n, as 2 to the inverse power n. For example, if
the value of this attribute is 6, RIF is 2E-6 = 1/64.
RIF controls the amount by which the cell transmission rate may
increase upon receipt of a backward Resource Management (RM)
cell. For example, if a backward RM cell is received with the
Congestion Indication (CI) and the No Increase (NI) fields both set
to 0, the Allowed Cell Rate (ACR) value would be increased by the
amount (RIF*ACR). The ACR is not allowed to exceed the Peak
Cell Rate (PCR), in which case the ACR is set to PCR.
For nailed-up connections, this attribute is determined by the
provisioned value of the rateIncreaseFactor attribute. For signalled
connections, it is indicated in the ABR Setup Parameters

atmIfVptTmAbrMaxCellPerRmCellThis attribute is applicable and is displayed only for connections for
which the operational Tm abrConnectionType is displayed as
sourceDest or virtualSourceDest.
This attribute indicates the maximum number of cells an ABR
source may transmit for each forward Resource Management (RM)
cell. The count of the cells transmitted includes data cells, OAM
cells, backward RM cells, and the forward RM cell.
For nailed-up connections, this attribute is determined by the
provisioned value of the maxCellsPerRmCell attribute. For
signalled connections, it is indicated in the ABR Additional

atmIfVptTmAbrMaxTimeBetweenRmCellThis attribute is applicable and is displayed only for connections for
which the operational Tm abrConnectionType is displayed as
sourceDest or virtualSourceDest.
This attribute indicates the TRM parameter for this connection.
TRM provides an upper bound on the time interval between forward
Resource Management (RM) cells for an ABR source. Since the last
forward RM cell was sent, if at least TRM time has elapsed since
and at least 2 other cells have been sent, the next cell to be
transmitted would be a forward RM cell.
For nailed-up connections, this attribute is determined by the
provisioned value of the maxTimeBetweenRmCell attribute. For
signalled connections, it is indicated in the ABR Additional
Parameters Information Element.ro Unsigned32 (781 | 1563 | 3125 | 6250 | 12500 | 25000 | 50000 | 100000) .1.3.6.1.4.1.3764.1.1.30.114.9.9.2.110.1.16 |
atmIfVptTmAbrCutoffDecreaseFactorThis attribute is applicable and is displayed only for connections for
which the operational Tm abrConnectionType is displayed as
sourceDest or virtualSourceDest.
This attribute indicates the Cutoff Decrease Factor (CDF) parameter
for this connection. When the value of this attribute is non-zero,
CDF is computed as the inverse of the value. For example, if the
value is 32, the value of CDF is 1/32. When the value of this
attribute is 0, CDF is also zero.
CDF controls the decrease in the Allowed Cell Rate (ACR)
associated with the forwardRmCellLimit attribute, the limit of the
number of forward Resource Management (RM) cells which may
be sent in the absence of received backward RM cells. When this
limit is crossed, the ACR value would be decreased by the amount
(CDF*ACR). The ACR is not allowed to fall below the Minimum
Cell Rate (MCR), in which case the ACR is set to MCR.
For nailed-up connections, this attribute is determined by the
provisioned value of the cutoffDecreaseFactor attribute. For
signalled connections, it is indicated in the ABR Additional

atmIfVptTmAbrAcrDecreaseTimeFactorThis attribute is applicable and is displayed only for connections for
which the operational Tm abrConnectionType is displayed as
sourceDest or virtualSourceDest.
This attribute indicates the Allowed Cell Rate Decrease Time Factor
(ADTF) parameter for this connection.
ADTF is the time interval permitted between sending forward
Resource Management (RM) cells before the Allowed Cell Rate
(ACR) is decreased to initialCellRate. In other words, if the source
does not transit a forward RM cell for the period specified by adtf, it
reduces its ACR to the value of its initialCellRate.

atmIfVptTmAbrForwardRmCellLimitThis attribute is applicable and is displayed only for connections for
which the operational Tm abrConnectionType is displayed as
sourceDest or virtualSourceDest.
This attribute indicates the CRM parameter for this connection.
CRM is the limit of the number of forward Resource Management
(RM) cells which may be sent in the absence of received backward
RM cells. When this limit is crossed, the Allowed Cell Rate (ACR)
value would be decreased by the amount (CDF*ACR), where CDF
is determined by the cutoffDecreaseFactor. The ACR is not allowed
to fall below the Minimum Cell Rate (MCR), in which case the
ACR is set to MCR.
The value of CRM is obtained as transientBufferExposure divided
by maxCellsPerRmCell.ro Unsigned32 (1 | 3 | 7 | 15 | 31 | 63 | 127 | 255 | 511 | 1023 | 2047 | 4095) .1.3.6.1.4.1.3764.1.1.30.114.9.9.2.110.1.19 |

This attribute value is only applicable when the Vcc Tm or Vpc Tm
abrConnectionType attribute is sourceDest or VirtualSourceDest.
In all other cases, this attribute value is notApplicable.
A value of noChange indicates that the rate did not change as a
result of the last backward RM cell received.
A value of decreasedByRdf or increasedByRif indicates that the
ACR was increased or decreased by the corresponding factor. This
change is as a result of the CI or NI bit setting in the last backward
RM cell, or an ADTF timeout.
A value of setToExplicitRate indicates that the ACR was set to the
ER value in the last backward RM cell.ro Enumeration .1.3.6.1.4.1.3764.1.1.30.114.9.9.2.110.1.21 |

atmIfVptTmAtmServiceCategoryThis attribute indicates the ATM service category used for traffic in
both directions of the connection. This attribute does not apply to
Virtual Link VPTs and will always be displayed as
constantBitRate.
The constantBitRate service category is intended for real time
applications, that is, those requiring tightly constrained delay and
delay variation, as would be appropriate for voice and video
applications. The consistent availability of a fixed quantity of
bandwidth is considered appropriate for CBR service. Cells which
are delayed beyond the value specified by Cell Transfer Delay are
assumed to have significantly reduced value for the application.
The rtVariableBitRate service category is intended for real time
applications; that is those requiring tightly constrained delay and
delay variation, as would be appropriate for voice and video
applications. Sources are expected to transmit at a rate which varies
with time. Equivalently, the source can be described as 'bursty'.
Cells which are delayed beyond the value specified by Cell Transfer
Delay are assumed to be of significantly reduced value to the
application. Real time VBR service may support statistical
multiplexing of real time sources.
The nrtVariableBitRate service category is intended for non-real
time applications which have bursty traffic characteristics and which
can be characterized in terms of a PCR, SCR, and MBS. For those
cells which are transferred within the traffic contract, the application
expects a low cell loss ratio. For all connections, it expects a bound
on the mean cell transfer delay. Non-real time VBR service may
support statistical multiplexing of connections.
The availableBitRate service is an ATM layer service category for
which the limiting ATM layer transfer characteristics provided by
the network may change subsequent to connection establishment.
ABR service has a flow control mechanism which supports several
types of feedback to control the source rate in response to changing
ATM layer transfer characteristics. ABR service is not intended to
support real-time applications.
The unspecifiedBitRate service is intended for non-real time
applications, that is those not requiring tightly constrained delay
and delay variation. UBR sources are expected to be bursty. UBR
service supports a high degree of statistical multiplexing among
sources. UBR service does not specify traffic related service
guarantees. No numerical commitments are made with respect to
the cell loss ratio experienced by a UBR connection, or as to the
cell transfer delay experienced by cells on the connection.ro Enumeration .1.3.6.1.4.1.3764.1.1.30.114.9.9.100.1.62 |
atmIfVptTmTrafficShapingThis attribute indicates the traffic shaping state of the connection.
A value of notApplicable indicates that traffic shaping is not
applicable or not supported for this connection. This is the case:
- when the txTrafficDescType is 1 or 2.
- for standard Vpt Vccs and basic Vpts.
- for CQC-based ATM cards, when the atmServiceCategory is
constantBitRate.
In these cases, the value of notApplicable is set regardless of
whether traffic shaping is enabled or disabled in the provisioning
data.
A value of disabled indicates that traffic shaping is applicable and
supported for the type of connection but has been turned off in the
provisioning data.
A value of linear or inverseUpc indicates that traffic shaping is
applicable and supported for the type of connection and has been
turned on in the provisioning data. This is the only case that
indicates that traffic shaping is performed on the connection. In this
case, the actual shaping rate is reflected in the txTrafficDescParm
attribute, parameter number 4. A value of linear indicates that
traffic is being shaped at the constant rate indicated in
txTrafficDescParm 4.
A value of inverseUpc is possible only on ATM IP cards. This value
indicates that the shaper strictly conforms to the requirements of a
dual leaky bucket UPC enforcer. This value is indicated if traffic
shaping is enabled, and the txTrafficDescType for this connection is
6, 7 or 8.
Traffic shaping for connections with atmServiceCategory as
availableBitRate (txTrafficDescType 9) depends upon the
abrConnectionType attribute. If abrConnectionType is sourceDest
or virtualSourceDest, the value of this attribute is dynamic. If
abrConnectionType is erSwitch or efciSwitch, this attribute is

atmIfVptTmBearerClassBbcThis attribute indicates the bearer capability for this connection.
Class a service is a connection-oriented, constant bit rate ATM
transport service. Class a service has end to end timing
requirements and may require stringent cell loss, cell delay and cell
delay variation performance.When a is displayed, the user is
requesting more than an ATM only service. The network may look
at the AAL to provide interworking based upon its contents.
Class c service is a connection-oriented, variable bit rate ATM
transport service. Class c service has no end-to-end timing
requirements.When c is displayed, the user is requesting more than
an ATM only service. The network interworking function may look
at the AAL and provide service based on it.
Class x service is a connection-oriented ATM transport service
where the AAL, trafficType (cbr or vbr), and timing requirements
are user defined (that is, transparent to the network). When the
value of this attribute is x, the user is requesting an ATM only
service from the network. In this case, the network shall not process
any higher layer protocol.
Class vp service is used to indicate a transparent VP service when
the user is requesting an ATM only service from the network. In this
case, the network does not process any higher layer protocol. This
service differs from class x service in that with the class vp service
both the VCI field (except for VCI values 0, 3, 4, and 6 through 15)
and Payload Type field are transported transparently by the network.

basis.ro Enumeration .1.3.6.1.4.1.3764.1.1.30.114.9.9.100.1.78 |
atmIfVptTmWeightThis attribute indicates the relative weight of this unshaped
connection. Connections with a larger weight get a larger proportion
of the link bandwidth, or in the case of standard Vpt Vccs, the Vpt
bandwidth.
For all but standard Vpt Vccs, the default connection weight is
determined by the weight policy for a service category and the
traffic descriptor for a connection. For standard Vpt Vccs, the
default connection weight is determined by the Vcc's service
category.
For CQC-based ATM cards, this attribute is not applicable and is
not displayed.
A value from 1 to 4095 indicates an actual weight. The value
upToQueueLimit indicates that the weight of a connection is up to
the transmit queue limit for this connection. upToQueueLimit is
used with common (first-in-first-out) queueing.
This attribute is displayed as notApplicable if:
- this connection has trafficShaping displayed as linear or
inverseUpc.
- this is a basic Vpt.

atmIfVptTmUsageParameterControlThis attribute indicates the UPC state of the connection.
A value of notApplicable indicates that UPC is not applicable or not
supported for the connection. This is the case:
- when the connection's rxTrafficDescType is 1 or 2.
- for standard Vpt Vccs and basic Vpts.
A value of notApplicable is set regardless of whether UPC is
disabled or enabled in provisioning data.
A value of disabled indicates that UPC is applicable and supported
for the type of connection but has been turned off in the
provisioning data.
A value of enforced indicates that UPC is actively checking
conformance for the connection and is discarding or tagging cells
which do not conform to the connection traffic contract. The traffic
descriptor parameters used for UPC conformance are reflected in
the rxTrafficDescParms of the connection. On ATM IP cards, the
counts of UPC violations are visible in the Vcc, Vpc, or Vpt
rxUpcViolationsOnEnforcer1 or rxUpcViolationsOnEnforcer2
attributes.
ATM IP cards provide the ability to monitor UPC violations without
tagging or discarding. A value of monitored indicates that UPC is
actively checking conformance for the connection and counting the
violations, but is not discarding or tagging cells which do not
conform to the connection traffic contract. The traffic descriptor
parameters used for UPC conformance are reflected in the
rxTrafficDescParms of the connection. The counts of UPC
violations are visible in the Vcc, Vpc, or Vpt
rxUpcViolationsOnEnforcer1 or rxUpcViolationsOnEnforcer2
attributes. The value of monitored appears only on ATM IP cards.
If the atmServiceCategory for this connection indicates
availableBitRate, a value of abrEnforced indicates that Dynamic
Generic Cell Rate Algorithm (DGCRA) is active for the connection
and that violating cells are discarded. The cell rate which is in effect
at any particular instant is indicated in rxTrafficDescParm 4 of the
connection.
If the atmServiceCategory for this connection indicates

atmIfVptTmTxPacketWiseDiscardThis attribute indicates the current set of packet-wise discard
functions in effect in the transmit data direction at this connection
point.
A value of ppd indicates that the Partial Packet Discard (PPD)
function is in effect. PPD may be applied at an intermediate
connecting point for a connection which is transporting frame traffic
(AAL5 at the endpoint). PPD is controlled by provisioning for
PVCs and SPVCs, and by call setup parameters in the AAL and
Traffic Descriptor Information Elements.
A value of epd indicates that the Early Packet Discard (EPD)
function is in effect at this connection endpoint. On CQC-based
ATM cards, PPD and EPD are enabled by default at a connection
endpoint which is performing AAL5 segmentation and assembly.
A value of wred indicates that Weighted Random Early Detection is
in effect at this connection point. W-RED can be enabled by
provisioning for PVCs and SPVCs.

atmIfVptTmBandwidthElasticThis attribute is only of importance for connections which are
carried on a link with a variable bandwidth. For example, the
bandwidth may be reduced in the event that one or more physical
links in the IMA group fail, such that the originally requested
bandwidth cannot be maintained. This attribute shows whether the
application (for example, Trunk) running on this connection can
continue to operate if the bandwidth is reduced. If the bandwidth is
reduced, the amount by which it is reduced is displayed in the
bandwidthReduction attribute.
A value of yes, indicates that this connection is elastic, and the
bandwidth may be reduced but the connection is not released.
A value of no indicates that the bandwidth for this connection is not
reduced in the event of link bandwidth reduction. However, this
connection may be released based on its holdingPriority.
Bandwidth elasticity has no effect for connections which have an
equivalent cell rate (ECR) of zero.
This attribute is not applicable for Vpts and Vpt Vccs.ro Enumeration .1.3.6.1.4.1.3764.1.1.30.114.9.9.100.1.90 |
atmIfVptTmBandwidthReductionThis attribute shows the amount by which the bandwidth has been
reduced for this connection. This value is non-zero only for
connections which have bandwidthElastic displayed as yes, and
which are also operating in a reduced bandwidth mode. This is
typically the case for selected connections running over an IMA
link. This attribute takes a value from 0 (no reduction) up to the
ECR. For all connections which are running at their full allocated
bandwidth, bwReduction has the value 0. Connections which have
been reduced in allocated bandwidth have a positive number for this
attribute. The bwReduction may be subtracted from the ECR (which
is displayed as txTrafficDescParm 5) to determine the actual
bandwidth allocated to this connection.ro Unsigned32 .1.3.6.1.4.1.3764.1.1.30.114.9.9.100.1.100 |
atmIfVptTmAbrConnectionTypeThis attribute indicates the type of ABR behavior which is in effect
at this connection. This attribute is only applicable if the
atmServiceCategory attribute is availableBitRate. If the
atmServiceCategory attribute is not availableBitRate, or if the
connection is not active, this attribute value is displayed as
notApplicable.
For CQC-based ATM cards, the only possible values are
notApplicable, efciSwitch or nonAbrInterworking. In EFCI
marking mode, the Explicit Forward Congestion Indication (EFCI)
field in the data cell headers is used to indicate transmit queue
congestion.
For ATM IP cards, if the connectionPointType is displayed as
connectionEndPoint, this attribute has the value sourceDest. In this
mode, the ABR Source and Destination behavior is in effect at this
connection. This attribute is also sourceDest in the case where the
next hop connection is specified as nonAbrInterworking. The next
hop connection is the Vcc or Vpc identified by the nextHop attribute
of the Nrp or Rp component.
If the connectionPointType is not connectionEndPoint, the value of
this attribute depends upon the abrConnectionType provisioning
and the card type to which the traffic is forwarded on the backplane.
The default abrConnectionType is provisioned at the CA Abr
abrConnectionType attribute, and may be overridden for a
provisioned connection in the Vcd Tm abrConnectionType or Vpd
Tm abrConnectionType attribute. If the CA Abr abrConnectionType
attribute is virtualSourceDest at either one of the two connection
points, and if both the connection points are defined on ATM IP
cards, virtual source and destination behavior is applied to the
connection. In this instance, the attribute displays the value
virtualSourceDest.
This attribute has the value erSwitch if ABR explicit rate
functionality is in effect at this connection. In this mode, the switch
may modify the Explicit Rate (ER) field of backward Resource
Management (RM) cells to indicate the status of congestion at this
connection point.
This attribute has the value nonAbrInterworking in the case where
this connection point is functioning as an SPVC origin for an ABR
connection where the link side of this connection is configured as a
non-ABR ATM service category. This means that there are no RM
cells on the link side of this connection, and that the next hop
connection point is performing as an ABR sourceDest.ro Enumeration .1.3.6.1.4.1.3764.1.1.30.114.9.9.100.1.110 |
atmIfVptTmTxTdpTableThis attribute is a vector of five transmit traffic parameters whose
mapping is defined by the txTrafficDescType attribute.
The values of peak cell rate (PCR), sustained cell rate (SCR),
Minimum Cell Rate (MCR), actual cell rate (ACR), explicit rate
(ER), equivalent cell rate (ECR), and actual shaping rate are
expressed in cell/s. Maximum burst size (MBS) is expressed in
cells. CDVT is expressed in microseconds.
When txTrafficDescType is 1 or 2, parameters 1 through 5 are
unused.
In this description, PCR is the greater of either the PCR or the
requested shaping rate (parameter 1 or parameter 5) specified in the
txTrafficDescParm attribute under the Vcd Tm or Vpd Tm
component.
When txTrafficDescType is 3, parameter 1 represents the PCR for
CLP equal to 0 or 1 traffic; parameters 2 and 3 are unused.
When txTrafficDescType is 4, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic; parameter 2 represents the PCR for
CLP equal to 0 traffic with cell discard.
When txTrafficDescType is 5, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic; parameter 2 represents the PCR for
CLP equal to 0 traffic with cell tagging.
When txTrafficDescType is 6, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic; parameter 2 represents the SCR for
CLP equal to 0 and 1 traffic; parameter 3 represents the MBS for
CLP equal to 0 and 1 traffic.
When txTrafficDescType is 7, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic; parameter 2 represents the SCR for
CLP equal to 0 traffic with cell discard; parameter 3 represents the
MBS for CLP equal to 0 traffic.
When txTrafficDescType is 8, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic; parameter 2 represents the SCR for
CLP equal to 0 traffic with cell tagging; parameter 3 represents the
MBS for CLP equal to 0 traffic.
When txTrafficDescType is 3, 4, 5, 6, 7, or 8, parameter 4 reflects
the actual shaping rate in cell/s for this connection. For CQC-based
ATM cards, the set of available shaping rates is based on the
number of interfaces doing shaping (attribute
perVcQueueInterfaces), and the shapingScalingFactor attribute of
the Arc Cqc Override component. A rate of zero (0) indicates that
shaping is not performed, or that the interface is down.
When txTrafficDescType is 9, parameter 1 represents the PCR;
parameter 2 represents the Cell Delay Variation Toleration (CDVT);
parameter 3 represents the Minimum Cell Rate (MCR); the meaning
of parameter 4 depends upon the value of the abrConnectionType
attribute. if abrConnectionType is sourceDest or
virtualSourceDest, parameter 4 represents the Allowed Cell Rate
(ACR); If abrConnectionType is erSwitch, parameter 4 represents
the Explicit Rate (ER); and if abrConnectionType is efciSwitch,
parameter 4 reflects the actual shaping rate in cell/s for this
connection.
When txTrafficDescType is 3, 4, 5, 6, 7, 8, or 9, parameter 5 reflects
the equivalent cell rate in cell/s for this connection as determined by
the Connection Admission Control (CAC) algorithm. The
equivalent cell rate is useful in determining the admission
characteristics of this connection. SEQUENCE OF AtmIfVptTmTxTdpEntry .1.3.6.1.4.1.3764.1.1.30.114.9.9.451 |

atmIfVptVccVcdTmAbrInitialCellRateThis attribute specifies the Initial Cell Rate (ICR) parameter for this
connection. ICR is the rate at which a source should send initially
and after an idle period.
When this attribute is set to sameAsCa, the initial cell rate is
determined by the AtmIf CA Abr/0 icr attribute. When the value of
this attribute is set to useMcr, ICR is set to the same value as the
Minimum Cell Rate (MCR) for the connection.
When the value of this attribute is set to usePcr, ICR is set to the
same value as the Peak Cell Rate (PCR) for the connection.
If this attribute is specified less than the MCR of the connection,
then the MCR is used as the ICR. If this attribute is specified more
than PCR of the connection, then PCR is used as the ICR.
This attribute is ignored under all conditions where the operational
attribute abrConnectionType indicates erSwitch or efciSwitch.

atmIfVptVccVcdTmAbrTransientBufferExposureThis attribute specifies the Transient Buffer Exposure (TBE) for this
connection. TBE is the negotiated number of cells that the network
would like to limit the source to send during start-up periods, before
the first Resource Management (RM) cell returns.
TBE divided by fixedRoundTripTime determines an upper bound
for the operational value of initialCellRate, the rate at which a
source should send initially and after an idle period.
TBE divided by maxCellsPerRmCell specifies the operational value
of forwardRmCellLimit, the limit of the number of forward
Resource Management (RM) cells which may be sent in the
absence of received backward RM cells.
This attribute is ignored under all conditions where the operational
attribute abrConnectionType is set to erSwitch.rw Unsigned32 .1.3.6.1.4.1.3764.1.1.30.114.9.20.2.2.2.110.1.11 |
atmIfVptVccVcdTmAbrFixedRoundTripTimeThis attribute specifies the Fixed Round-Trip Time (FRTT)
parameter for this connection. FRTT is the sum of the fixed and
propagation delays from the source to a destination and back.
The value of transientBufferExposure divided by the value of FRTT
(in seconds) determines an upper bound for the operational value of
initialCellRate, the rate at which a source should send initially and
after an idle period.
This attribute is ignored under all conditions where the operational
attribute abrConnectionType indicates erSwitch or efciSwitch.rw Unsigned32 .1.3.6.1.4.1.3764.1.1.30.114.9.20.2.2.2.110.1.12 |
atmIfVptVccVcdTmAbrRateDecreaseFactorThis attribute specifies the Rate Decrease Factor (RDF) for this
connection. The RDF value is computed by using the provisioned
value of this attribute, n, as 2 to the inverse power n. For example, if
the value of this attribute is 8, RDF is 2E-8 = 1/256.
RDF controls the amount by which the cell transmission rate may
decrease upon receipt of a backward Resource Management (RM)
cell. For example, if a backward RM cell is received with the
Congestion Indication (CI) field set to 1, the Allowed Cell Rate
(ACR) value would be reduced by the amount (RDF*ACR). The
ACR is not allowed to fall below the Minimum Cell Rate (MCR), in
which case the ACR is set to MCR.

atmIfVptVccVcdTmAbrRateIncreaseFactorThis attribute specifies the Rate Increase Factor (RIF) for this
connection. The RIF value is computed by using the provisioned
value of this attribute, n, as 2 to the inverse power n. For example, if
the value of this attribute is 6, RIF is 2E-6 = 1/64.
RIF controls the amount by which the cell transmission rate may
increase upon receipt of a backward Resource Management (RM)
cell. For example, if a backward RM cell is received with the
Congestion Indication (CI) and the No Increase (NI) fields both set
to 0, the Allowed Cell Rate (ACR) value would be increased by the
amount (RIF*ACR). The ACR is not allowed to exceed the Peak
Cell Rate (PCR), in which case the ACR is set to PCR.

atmIfVptVccVcdTmAbrMaxCellPerRmCellThis attribute specifies the maximum number of cells an ABR
source may transmit for each forward Resource Management (RM)
cell. The count of the cells transmitted includes data cells, OAM
cells, backward RM cells, and the forward RM cell.
A value of 2 is not recommended although it is permitted according
to the ATM Forum standard. When this attribute is set to a value of
2, it is possible that only one forward and one backward RM cell
are repeatedly transmitted, and all data traffic is queued up
indefinitely.

atmIfVptVccVcdTmAbrMaxTimeBetweenRmCellsThis attribute specifies the TRM parameter for this connection.
TRM provides an lower bound on the time interval between forward
Resource Management (RM) cells for an ABR source. Since the last
forward RM cell was sent, if at least TRM time has elapsed since
and at least two other cells have been sent, then the next cell to be
transmitted would be a forward RM cell.
This attribute is ignored under all conditions where the operational
attribute abrConnectionType has the value erSwitch.

atmIfVptVccVcdTmAbrCutoffDecreaseFactorThis attribute specifies the Cutoff Decrease Factor (CDF) parameter
for this connection. When the value of this attribute is non-zero,
CDF is computed as the inverse of the value. For example, if the
value is 32, the value of CDF is 1/32. When the value of this
attribute is 0, CDF is also zero.
CDF controls the decrease in the Allowed Cell Rate (ACR)
associated with the CRM parameter, the limit of the number of
forward Resource Management (RM) cells which may be sent in
the absence of received backward RM cells. When this limit is
crossed, the ACR value would be decreased by the amount
(CDF*ACR). The ACR is not allowed to fall below the Minimum
Cell Rate (MCR), in which case the ACR is set to MCR.
The value of CRM is indicated by the forwardRmCellLimit
attribute.

atmIfVptVccVcdTmAbrAcrDecreaseTimeFactorThis attribute specifies the Allowed Cell Rate Decrease Time Factor
(ADTF) parameter for this connection.
ADTF is the maximum time interval permitted between sending
forward Resource Management (RM) cells before the Allowed Cell
Rate (ACR) is decreased to initialCellRate. In other words, if the
source does not transit a forward RM cell for the period specified by
adtf, it reduces its ACR to the value of its initialCellRate.

atmIfVptVccVcdTmAbrDgcraMaximumDelayThis attribute specifies an upper bound on the delay after which the
rate change induced by a backward Resource Management (RM)
cell departing from this connection point (in the backward
direction) is expected to be observed at this connection point (in the
forward direction).
This upper bound may be approximated as the sum of the round trip
fixed and propagation delays and the maximum queuing delays
between the ABR source and this interface.
The value of this attribute is used in policing an ABR connection
using the Dynamic General Cell Rate Algorithm (DGCRA). A
larger value for this attribute implies a more lenient policer. When
there is a reduction in the Allowed Cell Rate (ACR), the policer
waits for a correspondingly longer period of time before it enforces
at the new cell rate.

The value of this attribute is used in policing an ABR connection
using the Dynamic Generic Cell Rate Algorithm (DGCRA). A
larger value for this attribute implies a more lenient policer. When
the delay between two consecutive forward Resource Management

atmIfVptVccVcdTmAtmServiceCategoryThis attribute specifies the ATM service category for both directions
of the connection.
The value derivedFromBBC may only be used if the SrcPvc
component is provisioned under this Vcc. Otherwise a specific
ATM service category must be specified.
If this attribute is set to derivedFromBBC, the Broadband Bearer
Capability (BBC) and bestEffort attributes are used to determine the
atmServiceCategory of this connection.
If this attribute is set to other than derivedFromBBC, the value of
this attribute is used to override the provisioned BBC Information
Element parameters. In those cases, the BBC attributes are not used.
The constantBitRate service category is intended for real time
applications, that is those requiring tightly constrained delay and
delay variation, as would be appropriate for voice and video
applications. The consistent availability of a fixed quantity of
bandwidth is considered appropriate for CBR service. Cells which
are delayed beyond the value specified by Cell Transfer Delay are
assumed to be of significantly reduced value to the application.
The rtVariableBitRate service category is intended for real time
applications, that is those requiring tightly constrained delay and
delay variation, as would be appropriate for voice and video
applications. Sources are expected to transmit at a rate which varies
with time. Equivalently, the source can be described as 'bursty'.
Cells which are delayed beyond the value specified by CTD are
assumed to be of significantly reduced value to the application. Real
time VBR service may support statistical multiplexing of real time
sources.
The nrtVariableBitRate service category is intended for non-real
time applications which have bursty traffic characteristics and which
can be characterized in terms of a PCR, SCR, and MBS. For those
cells which are transferred within the traffic contract, the application
expects a low cell loss ratio. For all connections, it expects a bound
on the mean cell transfer delay. Non-real time VBR service may
support statistical multiplexing of connections.
The availableBitRate service is an ATM layer service category for
which the limiting ATM layer transfer characteristics provided by
the network may change subsequent to connection establishment.
ABR service has a flow control mechanism which supports several
types of feedback to control the source rate in response to changing
ATM layer transfer characteristics. ABR service is not intended to
support real-time applications.
The unspecifiedBitRate service is intended for non-real time
applications; that is, those not requiring tightly constrained delay
and delay variation. UBR sources are expected to be bursty. UBR
service supports a high degree of statistical multiplexing among
sources. UBR service does not specify traffic related service
guarantees. No numerical commitments are made with respect to
the cell loss ratio experienced by a UBR connection, or as to the
cell transfer delay experienced by cells on the connection.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.114.9.20.2.2.100.1.42 |
atmIfVptVccVcdTmTrafficShapingThis attribute specifies whether this connection uses traffic shaping
when transmitting traffic to the ATM interface.
This attribute is ignored if the atmServiceCategory is
availableBitRate.
When sameAsCa is selected, traffic shaping for the connection is
based on the trafficShaping attribute of the connection's service
category component under the CA. If the service category has
trafficShaping set to enabled or inverseUpc, then traffic shaping is
enabled for the connection. Note that enabling traffic shaping may
have no effect under certain cases. These cases are listed in the
description of the trafficShaping operational attribute, which is

- if the atmServiceCategory is availableBitRate, or
- if the atmServiceCategory is constantBitRate and this is a CQC-
based ATM FP.

When this attribute is set to sameAsCa, the transmit queueing

When the value is set to sameAsCa, the weight is determined by the
fairnessWeight attribute under the CA service category component
for all but standard Vpt Vccs. For standard Vpt Vccs, the weight is
determined by the Vcc's service category, when the value is set to
sameAsCa.
When this attribute is set to a value from 1 to 4095, that value is
used for the fairness weight of this connection relative to other
connections. For all but standard Vpt Vccs, fairness weight
determines the proportion of transmit cell opportunities which are
allocated to this connection, compared to other connections in the
same service category. For standard Vpt Vccs, fairness weight
determines the proportion of transmit cell opportunities which are
allocated to this connection, compared to other connections
associated with the Vpt.
When the value is set to upToQueueLimit, the fairness weight is
limited only by the txQueueLimit.

selected, the CLP bit is set to 1 for all cells in the transmit direction.
Cells which are tagged are counted in the txCellClp attribute.
When the value is set to disabled, force tagging is disabled for cells
in the transmit direction on this connection. When this option is
selected, the CLP bit is unchanged for cells in the transmit
direction.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.114.9.20.2.2.100.1.62 |
atmIfVptVccVcdTmUsageParameterControlThis attribute specifies whether this connection enforces usage
parameter control when receiving traffic from the ATM interface.
When sameAsCa is selected, UPC for the connection is based on
the usageParameterControl attribute of the service category
component under the AtmIf CA. If the service category has UPC
enforced or monitored, then UPC is set to that value for the
connection.
When disabled is selected, UPC for this connection is disabled
regardless of the provisioning of the service category.
When enforced is selected, UPC for this connection is enforced
regardless of the provisioning of the service category.
ATM IP cards provide the ability to monitor UPC violations without
tagging or discarding. When monitored is selected, UPC is actively
checking conformance for the connection and counting the
violations, but is not discarding or tagging cells which do not
conform to the connection traffic contract.
If this is a connection of serviceCategory abr on an ATM IP card,
and the abrConnectionType is sourceDest, virtualSourceDest or
explicitRate, selecting enforced enables dynamic generic cell rate
algorithm (DGCRA) to discard violating cells. Selecting monitored
enables DGCRA to count violating cells.
Note that setting UPC to enforced or monitored may have no effect
under certain cases. These cases are listed in the description of the
usageParameterControl operational attribute, which is under the
Vcc, Vpc, and Vpt components.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.114.9.20.2.2.100.1.70 |
atmIfVptVccVcdTmBearerClassBbcThis attribute specifies the bearer capability. This attribute is only
used for SPVC and SPVP connections. It is one of the Broadband
Bearer Capability (BBC) attributes. The purpose of the BBC
information element is to indicate a requested broadband
connection-oriented bearer service to be provided by the network.
The value derivedFromServiceCategory specifies that the actual
value which is used for this connection is derived from the value of
the atmServiceCategory. Either, this attribute must be set to
derivedFromServiceCategory, or the atmServiceCategory attribute
must be set to derivedFromBBC, but not both.
Class a service is a connection-oriented, constant bit rate ATM
transport service. Class a service has end to end timing
requirements and may require stringent cell loss, cell delay and cell
delay variation performance.When a is set, the user is requesting
more than an ATM only service. The network may look at the AAL
to provide interworking based upon its contents.
Class c service is a connection-oriented, variable bit rate ATM
transport service. Class c service has no end-to-end timing
requirements. When c is set, the user is requesting more than an
ATM only service. The network interworking function may look at
the AAL and provide service based on it.
Class x service is a connection-oriented ATM transport service
where the AAL, trafficType (vbr or cbr) and timing requirements
are user defined (that is, transparent to the network).When x is set
the user is requesting an ATM only service from the network. In this
case, the network shall not process any higher layer protocol.
Class vp service is used to specify a transparent VP service. When
the value of this attribute is vp, the user is requesting an ATM only
service from the network. In this case, the network shall not process
any higher layer protocol. This service differs from class x service
in that with the class vp service both the VCI field (except or VCI
values 0, 3, 4, and 6 through 15) and Payload Type field are
transported transparently by the network. This attribute value is
only applicable to SPVP connections.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.114.9.20.2.2.100.1.71 |
atmIfVptVccVcdTmTransferCapabilityBbcThis attribute specifies the transfer capability for this connection.

0: NoIndication, NoIndication
1: NoIndication, yes
2: NoIndication, no
5: CBR, yes
8: VBR, NoIndication
9: VBR, yes
10: VBR, no
notApplicable specifies that the user does not want to specify the
transfer capability.
The CBR traffic type refers to traffic offered on services such as a
constant bit rate video service or a circuit emulation.
The VBR traffic type refers to traffic offered on services such as
packetized audio and video, or data.
The value no indication for traffic type is used if the user has not set
the traffic type; similarly for end-to-end timing.
The value yes for end-to-end timing indicates that end-to-end
timing is required.
The value no for end-to-end timing indicates that end-to-end timing
is not required.
The value derivedFromServiceCategory specifies that the actual

atmIfVptVccVcdTmTxWredThresholdThis attribute determines at what percentage of the queue being at
the EPD threshold, WRED starts. When the value is set to 25%,
WRED starts as soon as the queue is 25% of the way to the EPD
threshold. When the value is set to 50%, WRED starts later, after
the queue is 50% of the way to the EPD threshold. When the value
is set to 75%, WRED starts only when the queue is 75% of the way
to the EPD threshold. The EPD threshold is 85% of the transmit

atmIfVptVccVcdTmTxPacketWiseDiscardThis attribute specifies whether packet-wise discard functions are to
be enabled or disabled in the transmit data direction for this
connection. Packet-wise discard functions should only be requested
if this connection is transferring AAL5 frame traffic. This attribute
is not applicable for Vpts.
Packet-wise functions increase the 'goodput' of the link. The
transmit packet-wise functions are Early Packet Discard (EPD) and
Partial Packet Discard (PPD).
EPD allows the connection to discard an entire frame once the
transmit queue has reached the EPD threshold. EPD increases the
'goodput' of a link, since discarding an entire frame means that
some queue capacity is guarded for some other frame which is
already partially transmitted. All cells of the frame are discarded
from the Beginning of Message (BOM) cell up to and including the
End of Message (EOM) cell.
PPD allows the connection to discard the remainder of a cell-
forwarded AAL5 frame if one cell of this frame has been discarded.
All cells are discarded up to but not including the EOM cell. The
PPD function increases the 'goodput' of the link, since cells which
are only going to be discarded at the AAL5 reassembly point are
not transmitted.
On CQC-based ATM cards, the packet-wise discard functions are
PPD and EPD. PPD is available at VCC cell-transfer points. PPD is
not applicable at frame-cell conversion points, and is not applicable
for Vpcs. PPD is configured by this attribute. Packet-wise discard
should only be enabled for connections carrying AAL5
segmentation traffic. Setting the value to enabled for any other
traffic type may result in all traffic being discarded. On CQC-based
ATM FPs, EPD is automatically enabled at frame-to-cell conversion
points, independent of the setting of this attribute.
On ATM IP cards, packet-wise discard functions include EPD and
PPD. PPD and EPD apply to individual VCCs and VCCs within
VPCs at all connection points, including tandem VPC connections.
Both PPD and EPD are controlled by this attribute. This attribute
may safely be set to enabled for any connection (Vcc or Vpc) on
ATM IP FPs since they have the ability to automatically detect
AAL5-segmented traffic on a connection, and only enable packet-
wise discards if AAL5-segmented traffic is detected.
When this attribute is set to enabled, packet-wise discard functions
are applied to transmit traffic at this connection point. When this
attribute is set to disabled, packet-wise discard functions are not
applied to transmit traffic at this connection point.
At a SPVC origin on a PNNI interface, a value of enabled specifies
that frame discard is requested in the backward direction. When this
attribute is set to disabled, backward frame discard is not requested
in the SPVC call setup.
The transmit packet-wise discard functions that are active are
visible in the Vcc/Vpc Tm txPacketWiseDiscard operational
attribute.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.114.9.20.2.2.100.1.76 |
atmIfVptVccVcdTmTxWredModeThis attribute specifies the activation of weighted random early
detection (WRED) functionality. WRED is only available on ATM
IP FPs. On CQC-based ATM FPs, this attribute is ignored. If
txPacketWiseDiscard is set to disabled this attribute is ignored. This
attribute is not applicable for Vpts or Vpt Vccs.
WRED is applied in the transmit direction for this connection.
WRED function should be enabled only for connections which are
transferring TCP/IP traffic. WRED acts to prevent synchronization
of multiple TCP/IP sources by randomly discarding a small
percentage of frames when transmit queue congestion reaches the
designated level. W-RED may also be used to differentiate service
on VCC's by preferentially discarding one VCC before another.
Discards start at 0% of cells, when the queue is part-way to the
Early Packet Discard (EPD) threshold, and rise to 100% of cells
discarded at the EPD threshold. WRED discards all the cells in a
frame.
If this attribute is set to enabled, WRED is enabled for all
applications linked to the given Vcc. If it is set to perFlow, each
TCP application has individual control over whether to enable or
disable WRED
If txPacketWiseDiscard is set to disabled, or if this attribute is set to
disabled, WRED functionality is disabled.
If WRED is active, it is visible in the Vcc/Vpc Tm
txPacketWiseDiscard operational attribute.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.114.9.20.2.2.100.1.77 |
atmIfVptVccVcdTmRxPacketWiseDiscardThis attribute specifies whether packet-wise discard functions are to
be enabled or disabled in the receive data direction for this
connection. Packet-wise discard functions should only be requested
if this connection is transferring AAL5 frame traffic. This attribute
is not applicable for Vpts.
Packet-wise functions increase the 'goodput' of the link. The
receive packet-wise function is Partial Packet Discard (PPD).
PPD allows the connection to discard the remainder of a cell-
forwarded AAL5 frame if one cell of this frame has been discarded,
for example due to UPC. All cells are discarded up to but not
including the EOM cell. The PPD function increases the 'goodput'
of the link, since cells which are only going to be discarded at the
AAL5 reassembly point are not transmitted.
PPD is available at all VCC connection points where UPC may be
activated. PPD is not applicable for Vpcs.
On CQC-based ATM FPs, packet-wise discards should only be
enabled for connections carrying AAL5 segmentation traffic.
Setting the value to enabled for any other traffic type may result in
traffic being discarded.
On ATM IP cards, this attribute may safely be set to enabled for any
connection (Vcc or Vpc) since they have the ability to automatically
detect AAL5-segmented traffic on a connection, and only enables
packet-wise discards if AAL5-segmented traffic is detected.
When this attribute is set to enabled, packet-wise discard functions
are applied to receive traffic at this connection point. When this
attribute is set to disabled, packet-wise discard functions are not
applied to receive traffic at this connection point.
At a SPVC origin on a PNNI interface, a value of enabled specifies
that frame discard is requested in the forward direction. When this
attribute is set to disabled, forward frame discard is not requested in
the SPVC call setup.
The receive packet-wise discard functions that are active are visible
in the Vcc/Vpc Tm rxPacketWiseDiscard operational attribute.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.114.9.20.2.2.100.1.78 |
atmIfVptVccVcdTmAbrConnectionTypeThis attribute specifies the type of ABR behavior which is to be
enforced at this connection. This attribute is only applicable if the
atmServiceCategory attribute is availableBitRate. If the
atmServicecategory attribute is not availableBitRate, this attribute
value is ignored.
The actual ABR functionality which is in effect is visible in the
Vcc/Vpc/Vpt Tm abrConnectionType operational attribute.
For CQC-based ATM cards, the only allowable values are
sameAsCa, nonAbrInterworking or abrSwitch. If abrSwitch is
selected, the CQC implements EFCI marking behavior.
sameAsCa is used to request the default behavior as specified in the
CA Abr component for this Vcc. Otherwise, this attribute overrides
the default behavior.
virtualSourceDest is used to request that this connection point
function as a virtual source/virtual destination. VS/VD functionality
is only supported on ATM IP FPs.
sourceDest requires that this connection point function as a S/D for
RM cells. S/D mode is automatically invoked at this connection
point either if this is a connection end point, or if the next hop
connection point is configured as nonAbrInterworking.
nonAbrInterworking is used to request that this connection point
function as an interworking between ABR and non-ABR service
categories. This means that there are no RM cells on the link side of
this connection, and that the next hop connection point is
performing as an ABR sourceDest.
abrSwitch is used to request ABR switch behavior for this
connection point. The ABR switch behavior is first, to confirm to
virtualSourceDest or nonAbrInterworking setting on the next hop,
and otherwise to implement ABR ER switch behavior. For CQC-
based FPs, ABR switch behavior is implemented as EFCI marking.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.114.9.20.2.2.100.1.90 |
atmIfVptVccVcdTmTxTdpTableThis attribute is a vector of five traffic parameters whose meanings
are defined by the txTrafficDescType attribute.
The values of peak cell rate (PCR), sustained cell rate (SCR),
Minimum Cell Rate (MCR) and requested shaping rate are
expressed in cell/s. Maximum burst size (MBS) is expressed in
cells. CDVT is expressed in microseconds. The values of PCR,
SCR, MCR, MBS and CDVT are used for connection admission
control (CAC). The value of CDVT is only used for connections
where the atmServiceCategory is constantBitRate. For all other
values of atmServiceCategory, CDVT is ignored. The values of
PCR, SCR, MCR and requested shaping rate are used to determine
the actual shaping rate where traffic shaping is enabled.
When txTrafficDescType is 1 or 2, all of the parameters must be set
to zero.
When txTrafficDescType is 3, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic; parameter 4 represents the CDVT; and
parameter 5 represents the requested shaping rate. A non-zero value
in parameter 5 overrides any value in parameter 1. This result is
used as the PCR. Parameter 1 must be non-zero. Parameters 2 and 3
must be zero.
When txTrafficDescType is 4, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic with cell discard; parameter 2
represents the PCR for CLP equal to 0 traffic; parameter 4
represents the CDVT; and parameter 5 represents the requested
shaping rate. A non-zero value in parameter 5 overrides any value in
parameter 1. This result is used as the PCR. Parameter 1 must be
greater than or equal to parameter 2. Parameters 1 and 2 must be
non-zero. Parameter 3 must be zero.
When txTrafficDescType is 5, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic with cell tagging; parameter 2
represents the PCR for CLP equal to 0 traffic; parameter 4
represents the CDVT; and parameter 5 represents the requested
shaping rate. A non-zero value in parameter 5 overrides any value in
parameter 1. This result is used as the PCR. Parameter 1 must be
greater than or equal to parameter 2. Parameters 1 and 2 must be
non-zero. Parameter 3 must be zero.
When txTrafficDescType is 6, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic; parameter 2 represents the SCR for
CLP equal to 0 and 1 traffic; parameter 3 represents the MBS for
CLP equal to 0 and 1 traffic; parameter 4 represents the CDVT; and
parameter 5 represents the requested shaping rate. A non-zero value
in parameter 5 overrides any value in parameter 1. This result is
used as the PCR. Parameters 1, 2 and 3 must be non-zero.
Parameter 1 must be greater than or equal to parameter 2. Parameter
5, must either be zero (unused) or greater than or equal to parameter
2.
When txTrafficDescType is 7, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic; parameter 2 represents the SCR for
CLP equal to 0 with cell discard; parameter 3 represents the MBS
for CLP equal to 0 traffic; parameter 4 represents the CDVT; and
parameter 5 represents the requested shaping rate. A non-zero value
in parameter 5 overrides any value in parameter 1. This result is
used as the PCR. Parameters 1, 2 and 3 must be non-zero.
Parameter 1 must be greater than or equal to parameter 2. Parameter
5, must either be zero (unused) or greater than or equal to parameter
2.
When txTrafficDescType is 8, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic; parameter 2 represents the SCR for
CLP equal to 0 traffic with cell tagging; parameter 3 represents the
MBS for CLP equal to 0 traffic; parameter 4 represents the CDVT;
and parameter 5 represents the requested shaping rate. A non-zero
value in parameter 5 overrides any value in parameter 1. This result
is used as the PCR. Parameters 1, 2 and 3 must be non-zero.
Parameter 1 must be greater than or equal to parameter 2. Parameter
5, must either be zero (unused) or greater than or equal to parameter
2.
When txTrafficDescType is 9, parameter 1 represents the PCR;
parameter 2 represents the CDVT; parameter 3 represents the MCR;
parameter 4 and parameter 5 represent are not used and must be
zero. Parameter 1 must be non-zero and must be greater than or
equal to parameter 3. Parameter 3 may be optionally zero.
Whenever it is valid for PCR to be specified, parameter 5 may also
be used to specify a requested shaping rate. A non-zero value in
parameter 5 overrides the value in parameter 1 and is used as the
peak cell rate in calculations of CAC and shaping rate. When the
atmServiceCategory is availableBitRate (ABR), the shaping rate is
dynamically chosen, based on the ABR flow control mechanism, as
a value between the MCR and the PCR or the requested shaping
rate if applicable.
For txTrafficDescType 3, 4 and 5, the transmit traffic is shaped at
the next available shaping rate less than the PCR.
For txTrafficDescType 6, 7 and 8 if linear traffic shaping is selected,
the transmit traffic is shaped at the highest available rate which is
between PCR and SCR. However, if there is no available shaping
rate between PCR and SCR, traffic is shaped at the next rate above
the PCR.
For txTrafficDescType 6, 7 and 8 if inverse-UPC traffic shaping is
selected, the transmit traffic is shaped at a variable rate which
conforms to the PCR, SCR and MBS of the connection traffic
descriptor. Inverse-UPC traffic shaping is available only on ATM IP
cards. SEQUENCE OF AtmIfVptVccVcdTmTxTdpEntry .1.3.6.1.4.1.3764.1.1.30.114.9.20.2.2.456 |

When rxTrafficDescType is any value from 3 through 8, parameter
4 represents the CDVT.
If the value of CDVT either in parameter 2 or in parameter 4 is zero,
the CDVT is taken from the CA defaults for the particular
atmServiceCategory of this connection.
On a CQC-based ATM card, when rxTrafficDescriptorType is 3
through 8, there are certain extreme combinations of
rxTrafficDescParm which are outside the capabilities of the UPC
hardware. The check prov command detects such cases and
generates an error message. If this happens, adjust the parameters
until they fall within the supported limits.
To calculate the limits, use the following formulae:
I1 = 1 000 000 000 / PCR
L1 = CDVT * 1000
I2 = 1,000,000,000 / SCR
L2 = CDVT + (MBS - 1) * (I2 - I1)
I1 and I2 must be less than or equal to 335,523,840. I1 + L1 must
be less than or equal to 1,342,156,800. I2 + L2 must be less than or
equal to 1,342,156,800. Note that I2 and L2 only apply when the
rxTrafficDescriptorType is 6 through 8.
If the values of I1, L1, I2 or L2 are closer to the limits described
above, a further restriction applies. Specifically, if either:
I1 > 41,940,480 or
I2 > 41,940,480 or
I1 + L1 > 167,769,600 or
I2 + L2 > 167,769,600
then both I1 and I2 must be greater than 20,480.
Parameter 5 of the rxTrafficDescParm is always unused.
If the rxTrafficDescType is sameAsTx, the values provisioned in
this attribute are ignored. The traffic parameters for the receive
direction are taken from the txTrafficDescParm. SEQUENCE OF AtmIfVptVccVcdTmRxTdpEntry .1.3.6.1.4.1.3764.1.1.30.114.9.20.2.2.457 |

atmIfVptVccVcdAtmServiceCategoryThis attribute is migrated to the AtmTmProv group.
This attribute specifies the ATM service category for both directions
of the connection.
The value derivedFromBBC may only be used if the SrcPvc
component is provisioned under this Vcc.Otherwise a specific ATM
service category must be specified.
If this attribute is set to derivedFromBBC, the Broadband Bearer
Capability (BBC) and bestEffort attributes are used to determine the
atmServiceCategory of this connection.
If this attribute is set to other than derivedFromBBC, the value of
this attribute is used to override the provisioned BBC Information
Element parameters. In those cases, the BBC attributes are not used.
The constantBitRate service category is intended for real time
applications, that is those requiring tightly constrained delay and
delay variation, as would be appropriate for voice and video
applications. The consistent availability of a fixed quantity of
bandwidth is considered appropriate for CBR service. Cells which
are delayed beyond the value specified by Cell Transfer Delay are
assumed to be of significantly reduce value to the application.
The rtVariableBitRate service category is intended for real time
applications, that is those requiring tightly constrained delay and
delay variation, as would be appropriate for voice and video
applications. Sources are expected to transmit at a rate which varies
with time. Equivalently, the source can be described as 'bursty'.
Cells which are delayed beyond the value specified by CTD are
assumed to be of significantly reduced value to the application. Real
time VBR service may support statistical multiplexing of real time
sources.
The nrtVariableBitRate service category is intended for non-real
time applications which have bursty traffic characteristics and which
can be characterized in terms of a PCR, SCR, and MBS. For those
cells which are transferred within the traffic contract, the application
expects a low cell loss ratio. For all connections, it expects a bound
on the mean cell transfer delay. Non-real time VBR service may
support statistical multiplexing of connections.
The unspecifiedBitRate service is intended for non-real time
applications; that is, those not requiring tightly constrained delay
and delay variation. UBR sources are expected to be bursty. UBR
service supports a high degree of statistical multiplexing among
sources. UBR service does not specify traffic related service
guarantees. No numerical commitments are made with respect to
the cell loss ratio experienced by a UBR connection, or as to the
cell transfer delay experienced by cells on the connection.rwobsolete Enumeration .1.3.6.1.4.1.3764.1.1.30.114.9.20.2.110.1.42 |
atmIfVptVccVcdTrafficShapingThis attribute is migrated to the AtmTmProv group.
This attribute specifies whether this connection uses traffic shaping
when transmitting traffic to the ATM interface.
When sameAsInterface is selected, traffic shaping for the
connection is based on the trafficShaping attribute of the
connection's parent AtmIf componentif the ATM interface has
traffic shaping enabled, then traffic shaping is enabled for the
connection. Note that enabling traffic shaping may have no effect
under certain cases. These cases are listed in the description of the
trafficShaping operational attribute, which is under the Vcc and Vpc

When sameAsInterface is selected, UPC for the connection is
based on the usageParameterControl attribute of the connection's
parent AtmIf componentif the ATM interface has UPC enabled,
then UPC is enabled for the connection. Note that enabling UPC
may have no effect under certain cases. These cases are listed in the

atmIfVptVccVcdBearerClassBbcThis attribute is migrated to the AtmTmProv group.
This attribute specifies the bearer capability. This attribute is only
used for SPVC and SPVP connections. It is one of the Broadband
Bearer Capability (BBC) attributes. The purpose of the BBC
information element is to indicate a requested broadband
connection-oriented bearer service to be provided by the network.
The value derivedFromServiceCategory specifies that the actual
value which is used for this connection is derived from the value of
the atmServiceCategory. Either, this attribute must be set to
derivedFromServiceCategory, or the atmServiceCategory attribute
must be set to derivedFromBBC, but not both.
Class a service is a connection-oriented, constant bit rate ATM
transport service. Class a service has end to end timing
requirements and may require stringent cell loss, cell delay and cell
delay variation performance.When a is set, the user is requesting
more than an ATM only service. The network may look at the AAL
to provide interworking based upon its contents.
Class c service is a connection-oriented, variable bit rate ATM
transport service. Class c service has no end-to-end timing
requirements. When c is set, the user is requesting more than an
ATM only service. The network interworking function may look at
the AAL and provide service based on it.
Class x service is a connection-oriented ATM transport service
where the AAL, trafficType (vbr or cbr) and timing requirements
are user defined (that is, transparent to the network).When x is set
the user is requesting an ATM only service from the network.
Class vp service is used to specify a transparent VP service. When
the value of this attribute is vp, the user is requesting an ATM only
service from the network. In this case, the network shall not process
any higher layer protocol. This service differs from class x service
in that with the class vp service both the VCI field (except or VCI
values 0, 3, 4, and 6 through 15) and Payload Type field are
transported transparently by the network. This attribute value is
only applicable to SPVP connections.rwobsolete Enumeration .1.3.6.1.4.1.3764.1.1.30.114.9.20.2.110.1.71 |
atmIfVptVccVcdTransferCapabilityBbcThis attribute is migrated to the AtmTmProv group.
This attribute specifies the transfer capability for this connection.
Uni 3.0/3.1 traffic type and end-to-end timing parameters are

0: NoIndication, NoIndication
1: NoIndication, yes
2: NoIndication, no
5: CBR, yes
8: VBR, NoIndication
9: VBR, yes
10: VBR, no
NotApplicable specifies that the user does not want to specify the
transfer capability.
The CBR traffic type refers to traffic offered on services such as a
constant bit rate video service or a circuit emulation.
The VBR traffic type refers to traffic offered on services such as
packetized audio and video, or data.
The value no indication for traffic type is used if the user has not set
the traffic type; similarly for end-to-end timing.
The value yes for end-to-end timing indicates that end-to-end
timing is required.
The value no for end-to-end timing indicates that end-to-end timing
is not required.
The value derivedFromServiceCategory specifies that the actual

atmIfVptVccVcdFwdFrameDiscardThis attribute specifies the activation of frame discard functionality
in the forward data direction, at relay points, for this connection. It
applies to each hop of the connection. Frame discard functions
should not be requested if this connection is not transferring frame
(AAL5) traffic. Setting the value to indicated for any other traffic
type results in all traffic being discarded.
If this connection point is a permanent (provisioned) VCC mid-
point, this attribute specifies whether the Partial Packet
Discard (PPD) function is to be enabled or disabled in the transmit
direction at this connecting point. The PPD function allows the
connecting point to discard the remainder of a cell-forwarded AAL5
frame if one cell of this frame has been discarded. The PPD
function increases the 'goodput' of the link, since cells which are
only going to be discarded by the AAL5 reassembly are not
transmitted.
At a permanent VCC connecting point which is not a connection
endpoint, when this attribute is set to indicated, the PPD function is
applied to transmit traffic at this connecting point. It should not be
indicated for connections whose end points are not performing
AAL5 segmentation and reassembly. When this attribute is set to
notIndicated, the PPD feature is not applied to transmit traffic at
this connecting point.
At a SPVC origin on a PNNI interface, a value of indicated
specifies that frame discard is requested in the forward direction.
The frame discard function for SPVCs consists of PPD at the SPVC
origin and at all intermediate connecting points. When this attribute
is set to notIndicated, forward frame discard is not requested in the
SPVC call setup. Thus PPD is not enabled at the SPVC origin nor at
any intermediate connecting point.
At all points along a VPC, this setting is ignored.
At a permanent VCC connection endpoint, this value is ignored. If
AAL5 segmentation and reassembly has been requested, PPD and
Early Packet Discard (EPD) are automatically enabled.

atmIfVptVccVcdBwdFrameDiscardThis attribute specifies the activation of frame discard functionality
in the backward data direction, at relay points, for this connection.
It applies to each hop of the connection. Frame discard functions
should not be requested if this connection is not transferring frame
(AAL5) traffic. Setting the value to indicated for any other traffic
type results in all traffic being discarded.
If this connection point is a permanent (provisioned) VCC mid-
point, this attribute specifies whether the Partial Packet Discard
(PPD) function is to be enabled or disabled in the receive direction
at this connecting point. The PPD function allows the connecting
point to discard the remainder of a cell-forwarded AAL5 frame if
one cell of this frame has been discarded. The PPD function
increases the 'goodput' of the link, since cells which are only going
to be discarded by the AAL5 reassembly are not received.
At a permanent VCC connecting point which is not a connection
endpoint, when this attribute is set to indicated, the PPD function is
applied to receive traffic at this connecting point. It should not be
indicated for connections whose end points are not performing
AAL5 segmentation and reassembly. When this attribute is set to
notIndicated, the PPD feature is not applied to receive traffic at this
connecting point.
At a SPVC origin on a PNNI interface, a value of indicated
specifies that frame discard is requested in the backward direction.
The frame discard function for SPVCs consists of PPD at the SPVC
origin and at all intermediate connecting points. When this attribute
is set to notIndicated, backwards frame discard is not requested in
the SPVC call setup. Thus PPD is not enabled at the SPVC origin
nor at any intermediate connecting point.
At all points along a VPC, this setting is ignored.
At a permanent VCC connection endpoint, this value is ignored. If

(CAC). The value of CDVT is only used for connections where the
atmServiceCategory is constantBitRate. For all other values of
atmServiceCategory, CDVT is ignored. The values of PCR, SCR
and requested shaping rate are used to determine the actual shaping
rate where traffic shaping is enabled.
When txTrafficDescType is 1 or 2, all of the parameters must be set
to zero.
When txTrafficDescType is 3, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic; parameter 4 represents the CDVT; and
parameter 5 represents the requested shaping rate. A non-zero value
in parameter 5 overrides any value in parameter 1. This result is
used as the PCR. Parameter 1 must be non-zero. Parameters 2 and 3
must be zero.
When txTrafficDescType is 4, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic with cell discard; parameter 2
represents the PCR for CLP equal to 0 traffic; parameter 4
represents the CDVT; and parameter 5 represents the requested
shaping rate. A non-zero value in parameter 5 overrides any value in
parameter 1. This result is used as the PCR. Parameter 1 must be
greater than or equal to parameter 2. Parameters 1 and 2 must be
non-zero. Parameter 3 must be zero.
When txTrafficDescType is 5, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic with cell tagging; parameter 2
represents the PCR for CLP equal to 0 traffic; parameter 4
represents the CDVT; and parameter 5 represents the requested
shaping rate. A non-zero value in parameter 5 overrides any value in
parameter 1. This result is used as the PCR. Parameter 1 must be
greater than or equal to parameter 2. Parameters 1 and 2 must be
non-zero. Parameter 3 must be zero.
When txTrafficDescType is 6, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic; parameter 2 represents the SCR for
CLP equal to 0 and 1 traffic; parameter 3 represents the MBS for
CLP equal to 0 and 1 traffic; parameter 4 represents the CDVT; and
parameter 5 represents the requested shaping rate. A non-zero value
in parameter 5 overrides any value in parameter 1. This result is
used as the PCR. Parameters 1, 2 and 3 must be non-zero.
Parameter 1 must be greater than or equal to parameter 2. Parameter
5, must either be zero (unused) or greater than or equal to parameter
2.
When txTrafficDescType is 7, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic; parameter 2 represents the SCR for
CLP equal to 0 with cell discard; parameter 3 represents the MBS
for CLP equal to 0 traffic; parameter 4 represents the CDVT; and
parameter 5 represents the requested shaping rate. A non-zero value
in parameter 5 overrides any value in parameter 1. This result is
used as the PCR. Parameters 1, 2 and 3 must be non-zero.
Parameter 1 must be greater than or equal to parameter 2. Parameter
5, must either be zero (unused) or greater than or equal to parameter
2.
When txTrafficDescType is 8, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic; parameter 2 represents the SCR for
CLP equal to 0 traffic with cell tagging; parameter 3 represents the
MBS for CLP equal to 0 traffic; parameter 4 represents the CDVT;
and parameter 5 represents the requested shaping rate. A non-zero
value in parameter 5 overrides any value in parameter 1. This result
is used as the PCR. Parameters 1, 2 and 3 must be non-zero.
Parameter 1 must be greater than or equal to parameter 2. Parameter
5, must either be zero (unused) or greater than or equal to parameter
2.
Whenever it is valid for PCR to be specified, parameter 5 may also
be used to specify a requested shaping rate. A non-zero value in
parameter 5 overrides the value in parameter 1 and is used as the
peak cell rate in calculations of CAC and shaping rate.
For txTrafficDescType 3, 4 and 5, the transmit traffic is shaped at
the next rate less than the PCR.
For txTrafficDescType 6, 7 and 8, the transmit traffic is shaped at
the highest available rate which is between PCR and SCR.
However, if there is no available shaping rate between PCR and
SCR, traffic is shaped at the next rate above the PCR.obsolete SEQUENCE OF AtmIfVptVccVcdTxTdpEntry .1.3.6.1.4.1.3764.1.1.30.114.9.20.2.297 |

atmIfVptVccVcdRxTdpTableThis attribute is migrated to the AtmTmProv group.
This attribute is a vector of four traffic parameters whose meanings
are defined by the rxTrafficDescType attribute. The values of peak
cell rate (PCR) and sustained cell rate (SCR) are expressed in
cell/s. Maximum burst size (MBS) is expressed in cells. The value
of CDVT is expressed in microseconds. The values of PCR, SCR,
MBS and CDVT are used for usage parameter control (UPC).
When rxTrafficDescType is 1 or 2, all of the parameters must be set
to zero (unused).
When rxTrafficDescType is 3, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic. Parameter 1 must be non-zero.
Parameters 2 and 3 must be set to zero (unused).
When rxTrafficDescType is 4, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic; parameter 2 represents the PCR for
CLP equal to 0 traffic with cell discard. Parameters 1 and 2 must be
non-zero. Parameter 3 must be set to zero (unused). Parameter 1
must be greater than or equal to parameter 2.
When rxTrafficDescType is 5, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic; parameter 2 represents the PCR for
CLP equal to 0 traffic with cell tagging. Parameters 1 and 2 must be
non-zero. Parameter 3 must be set to zero (unused). Parameter 1
must be greater than or equal to parameter 2.
When rxTrafficDescType is a 6, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic; parameter 2 represents the SCR for
CLP equal to 0 and 1 traffic; parameter 3 represents the MBS for
CLP equal to 0 and 1 traffic. Parameters 1, 2 and 3 must be non-
zero. Parameter 1 must be greater than or equal to Parameter 2.
When rxTrafficDescType is 7, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic; parameter 2 represents the SCR for
CLP equal to 0 traffic with cell discard; parameter 3 represents the
MBS for CLP equal to 0 traffic. Parameters 1, 2 and 3 must be non-
zero. Parameter 1 must be greater than or equal to parameter 2.
When rxTrafficDescType is 8, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic; parameter 2 represents the SCR for
CLP equal to 0 traffic with cell tagging; parameter 3 represents the
MBS for CLP equal to 0 traffic. Parameter 1, 2 and 3 must be non-
zero. Parameter 1 must be greater than or equal to parameter 2.
When rxTrafficDescType is any value from 3 through 8, parameter
4 represents the CDVT. If this value is zero, the CDVT is taken
from the ConnectionAdministrator defaults for the particular
atmServiceCategory of this connection.
When rxTrafficDescriptorType is 3 through 8, there are certain
extreme combinations of rxTrafficDescParm which are outside the
capabilities of the UPC hardware. The check prov command detects
such cases and generates an error message. If this happens, adjust
the parameters until they fall within the supported limits.
To calculate the limits, use the following formulae:
I1 = 1 000 000 000 / PCR
L1 = CDVT * 1000
I2 = 1 000 000 000 / SCR
L2 = CDVT + (MBS - 1) * (I2 - I1)
I1 and I2 must be less than or equal to 335 523 840. I1 + L1 must
be less than or equal to 1 342 156 800. I2 + L2 must be less than or
equal to 1 342 156 800. Note that I2 and L2 only apply when the
rxTrafficDescriptorType is 6 through 8.
If the values of I1, L1, I2 or L2 are closer to the limits described
above, a further restriction applies. Specifically, if either:
I1 > 41 940 480 or
I2 > 41 940 480 or
I1 + L1 > 167 769 600 or
I2 + L2 > 167 769 600
then both I1 and I2 must be greater than 20 480.
Parameter 5 of the rxTrafficDescParm is always unused.
If the rxTrafficDescType is sameAsTx, the values in this attribute
are taken from the txTrafficDescParm.obsolete SEQUENCE OF AtmIfVptVccVcdRxTdpEntry .1.3.6.1.4.1.3764.1.1.30.114.9.20.2.298 |

test is intended to verify the operation of the connection under a
specified load. These frames are not checked for bit errors.
verification: A single 'verification frame' is transmitted over the
link; when the frame is returned, its contents are verified and the
next verification frame in the series is transmitted. This frame type

atmIfVptVccTestBandwidthElasticThis attribute specifies whether the connection (VCC) should be
configured with elastic bandwidth or not. Elastic bandwidth is of
importance in conjuction with IMA links, where some links fail and
the resulting bandwidth is less than the requested bandwidth for all
connections. In that case, some connections may be reduced in
bandwidth based on the setting of the bwElastic attribute.
If this attribute is set to yes, the Test application signals to the
connection that the bandwidth for this connection is elastic, and
may be reduced in the case of IMA link failures. If the bandwidth is
reduced, the rate of test cells which can be handled by the
connection will also be reduced.
If this attribute is set to no, the Test application signals to the
connection that the bandwidth for this connection must be
maintained at the requested level. If the connection cannot maintain
the full bandwidth, the connection may be released (cleared) based
on the holding priority of the connection.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.114.9.20.6.110.1.60 |
atmIfVptVccTestOverrideHoldingPriorityThis attribute specifies the override holding priority which should
be signalled to the VCC connection at the start of the test. Holding
priority is of importance in conjuction with IMA links, where some
links fail and the resulting bandwidth is less than the requested
bandwidth for all connections. In that case, some connections may
be released based on the connection's holding priority.
Zero (0) is thie highest holding priority, and four (4) is the lowest
priority. A setting of zero to four overrides whatever holding
priority that has been configured at the connection (VCC). A setting
of noOverride means that the connection should use its internally

and after an idle period.
For nailed-up connections, this attribute is determined by the
provisioned value of the initialCellRate attribute. For signalled
connections, it is indicated in the ABR Setup Parameters
Information Element.
The ICR for a connection is a value between the MCR and the PCR.

atmIfVptVccTmAbrRateDecreaseFactorThis attribute is applicable and is displayed only for connections for
which the operational Tm abrConnectionType is displayed as
sourceDest or virtualSourceDest.
This attribute indicates the Rate Decrease Factor (RDF) for this
connection. The RDF value is computed by using the operational
value of this attribute, n, as 2 to the inverse power n. For example, if
the value of this attribute is 8, RDF is 2E-8 = 1/256.
RDF controls the amount by which the cell transmission rate may
decrease upon receipt of a backward Resource Management (RM)
cell. For example, if a backward RM cell is received with the
Congestion Indication (CI) field set to 1, the Allowed Cell Rate
(ACR) value would be reduced by the amount (RDF*ACR). The
ACR is not allowed to fall below the Minimum Cell Rate (MCR), in
which case the ACR is set to MCR.
For nailed-up connections, this attribute is determined by the
provisioned value of the rateDecreaseFactor attribute. For signalled
connections, it is indicated in the ABR Setup Parameters

atmIfVptVccTmAbrRateIncreaseFactorThis attribute is applicable and is displayed only for connections for
which the operational Tm abrConnectionType is displayed as
sourceDest or virtualSourceDest.
This attribute indicates the Rate Increase Factor (RIF) for this
connection. The RIF value is computed by using the operational
value of this attribute, n, as 2 to the inverse power n. For example, if
the value of this attribute is 6, RIF is 2E-6 = 1/64.
RIF controls the amount by which the cell transmission rate may
increase upon receipt of a backward Resource Management (RM)
cell. For example, if a backward RM cell is received with the
Congestion Indication (CI) and the No Increase (NI) fields both set
to 0, the Allowed Cell Rate (ACR) value would be increased by the
amount (RIF*ACR). The ACR is not allowed to exceed the Peak
Cell Rate (PCR), in which case the ACR is set to PCR.

This attribute indicates the maximum number of cells an ABR
source may transmit for each forward Resource Management (RM)
cell. The count of the cells transmitted includes data cells, OAM
cells, backward RM cells, and the forward RM cell.
For nailed-up connections, this attribute is determined by the
provisioned value of the maxCellsPerRmCell attribute. For
signalled connections, it is indicated in the ABR Additional
Parameters Information Element.ro Unsigned32 (2 | 4 | 8 | 16 | 32 | 64 | 128 | 256) .1.3.6.1.4.1.3764.1.1.30.114.9.20.7.2.110.1.15 |
atmIfVptVccTmAbrMaxTimeBetweenRmCellThis attribute is applicable and is displayed only for connections for
which the operational Tm abrConnectionType is displayed as
sourceDest or virtualSourceDest.
This attribute indicates the TRM parameter for this connection.
TRM provides an upper bound on the time interval between forward
Resource Management (RM) cells for an ABR source. Since the last
forward RM cell was sent, if at least TRM time has elapsed since
and at least 2 other cells have been sent, the next cell to be
transmitted would be a forward RM cell.
For nailed-up connections, this attribute is determined by the
provisioned value of the maxTimeBetweenRmCell attribute. For
signalled connections, it is indicated in the ABR Additional
Parameters Information Element.ro Unsigned32 (781 | 1563 | 3125 | 6250 | 12500 | 25000 | 50000 | 100000) .1.3.6.1.4.1.3764.1.1.30.114.9.20.7.2.110.1.16 |
atmIfVptVccTmAbrCutoffDecreaseFactorThis attribute is applicable and is displayed only for connections for
which the operational Tm abrConnectionType is displayed as
sourceDest or virtualSourceDest.
This attribute indicates the Cutoff Decrease Factor (CDF) parameter
for this connection. When the value of this attribute is non-zero,
CDF is computed as the inverse of the value. For example, if the
value is 32, the value of CDF is 1/32. When the value of this
attribute is 0, CDF is also zero.
CDF controls the decrease in the Allowed Cell Rate (ACR)
associated with the forwardRmCellLimit attribute, the limit of the
number of forward Resource Management (RM) cells which may
be sent in the absence of received backward RM cells. When this
limit is crossed, the ACR value would be decreased by the amount
(CDF*ACR). The ACR is not allowed to fall below the Minimum
Cell Rate (MCR), in which case the ACR is set to MCR.
For nailed-up connections, this attribute is determined by the
provisioned value of the cutoffDecreaseFactor attribute. For
signalled connections, it is indicated in the ABR Additional

atmIfVptVccTmAbrAcrDecreaseTimeFactorThis attribute is applicable and is displayed only for connections for
which the operational Tm abrConnectionType is displayed as
sourceDest or virtualSourceDest.
This attribute indicates the Allowed Cell Rate Decrease Time Factor
(ADTF) parameter for this connection.
ADTF is the time interval permitted between sending forward
Resource Management (RM) cells before the Allowed Cell Rate
(ACR) is decreased to initialCellRate. In other words, if the source
does not transit a forward RM cell for the period specified by adtf, it
reduces its ACR to the value of its initialCellRate.

This attribute indicates the CRM parameter for this connection.
CRM is the limit of the number of forward Resource Management
(RM) cells which may be sent in the absence of received backward
RM cells. When this limit is crossed, the Allowed Cell Rate (ACR)
value would be decreased by the amount (CDF*ACR), where CDF
is determined by the cutoffDecreaseFactor. The ACR is not allowed
to fall below the Minimum Cell Rate (MCR), in which case the
ACR is set to MCR.
The value of CRM is obtained as transientBufferExposure divided
by maxCellsPerRmCell.ro Unsigned32 (1 | 3 | 7 | 15 | 31 | 63 | 127 | 255 | 511 | 1023 | 2047 | 4095) .1.3.6.1.4.1.3764.1.1.30.114.9.20.7.2.110.1.19 |

atmIfVptVccTmAtmServiceCategoryThis attribute indicates the ATM service category used for traffic in
both directions of the connection. This attribute does not apply to
Virtual Link VPTs and will always be displayed as
constantBitRate.
The constantBitRate service category is intended for real time
applications, that is, those requiring tightly constrained delay and
delay variation, as would be appropriate for voice and video
applications. The consistent availability of a fixed quantity of
bandwidth is considered appropriate for CBR service. Cells which
are delayed beyond the value specified by Cell Transfer Delay are
assumed to have significantly reduced value for the application.
The rtVariableBitRate service category is intended for real time
applications; that is those requiring tightly constrained delay and
delay variation, as would be appropriate for voice and video
applications. Sources are expected to transmit at a rate which varies
with time. Equivalently, the source can be described as 'bursty'.
Cells which are delayed beyond the value specified by Cell Transfer
Delay are assumed to be of significantly reduced value to the
application. Real time VBR service may support statistical
multiplexing of real time sources.
The nrtVariableBitRate service category is intended for non-real
time applications which have bursty traffic characteristics and which
can be characterized in terms of a PCR, SCR, and MBS. For those
cells which are transferred within the traffic contract, the application
expects a low cell loss ratio. For all connections, it expects a bound
on the mean cell transfer delay. Non-real time VBR service may
support statistical multiplexing of connections.
The availableBitRate service is an ATM layer service category for
which the limiting ATM layer transfer characteristics provided by
the network may change subsequent to connection establishment.
ABR service has a flow control mechanism which supports several
types of feedback to control the source rate in response to changing
ATM layer transfer characteristics. ABR service is not intended to
support real-time applications.
The unspecifiedBitRate service is intended for non-real time
applications, that is those not requiring tightly constrained delay
and delay variation. UBR sources are expected to be bursty. UBR
service supports a high degree of statistical multiplexing among
sources. UBR service does not specify traffic related service
guarantees. No numerical commitments are made with respect to
the cell loss ratio experienced by a UBR connection, or as to the
cell transfer delay experienced by cells on the connection.ro Enumeration .1.3.6.1.4.1.3764.1.1.30.114.9.20.7.100.1.62 |
atmIfVptVccTmTrafficShapingThis attribute indicates the traffic shaping state of the connection.
A value of notApplicable indicates that traffic shaping is not
applicable or not supported for this connection. This is the case:
- when the txTrafficDescType is 1 or 2.
- for standard Vpt Vccs and basic Vpts.
- for CQC-based ATM cards, when the atmServiceCategory is
constantBitRate.
In these cases, the value of notApplicable is set regardless of
whether traffic shaping is enabled or disabled in the provisioning
data.
A value of disabled indicates that traffic shaping is applicable and
supported for the type of connection but has been turned off in the
provisioning data.
A value of linear or inverseUpc indicates that traffic shaping is
applicable and supported for the type of connection and has been
turned on in the provisioning data. This is the only case that
indicates that traffic shaping is performed on the connection. In this
case, the actual shaping rate is reflected in the txTrafficDescParm
attribute, parameter number 4. A value of linear indicates that
traffic is being shaped at the constant rate indicated in
txTrafficDescParm 4.
A value of inverseUpc is possible only on ATM IP cards. This value
indicates that the shaper strictly conforms to the requirements of a
dual leaky bucket UPC enforcer. This value is indicated if traffic
shaping is enabled, and the txTrafficDescType for this connection is
6, 7 or 8.
Traffic shaping for connections with atmServiceCategory as
availableBitRate (txTrafficDescType 9) depends upon the
abrConnectionType attribute. If abrConnectionType is sourceDest
or virtualSourceDest, the value of this attribute is dynamic. If
abrConnectionType is erSwitch or efciSwitch, this attribute is
notApplicable.ro Enumeration .1.3.6.1.4.1.3764.1.1.30.114.9.20.7.100.1.70 |
atmIfVptVccTmBearerClassBbcThis attribute indicates the bearer capability for this connection.
Class a service is a connection-oriented, constant bit rate ATM
transport service. Class a service has end to end timing
requirements and may require stringent cell loss, cell delay and cell
delay variation performance.When a is displayed, the user is
requesting more than an ATM only service. The network may look
at the AAL to provide interworking based upon its contents.
Class c service is a connection-oriented, variable bit rate ATM
transport service. Class c service has no end-to-end timing
requirements.When c is displayed, the user is requesting more than
an ATM only service. The network interworking function may look
at the AAL and provide service based on it.
Class x service is a connection-oriented ATM transport service
where the AAL, trafficType (cbr or vbr), and timing requirements
are user defined (that is, transparent to the network). When the
value of this attribute is x, the user is requesting an ATM only
service from the network. In this case, the network shall not process
any higher layer protocol.
Class vp service is used to indicate a transparent VP service when
the user is requesting an ATM only service from the network. In this
case, the network does not process any higher layer protocol. This
service differs from class x service in that with the class vp service
both the VCI field (except for VCI values 0, 3, 4, and 6 through 15)
and Payload Type field are transported transparently by the network.
This attribute value is only applicable to SPVP and SVP
connections.

10: VBR, no
A value of notApplicable is displayed in the case of nailed-up PVCs
for which this attribute has no significance, or in the case that the
transfer capability in the call request was set to NoIndication.
The CBR traffic type refers to traffic offered on services such as a
constant bit rate video service or a circuit emulation.
The VBR traffic type refers to traffic offered on services such as
packetized audio and video, or data.
The value NoIndication for traffic type is used if the user has not set
the traffic type; similarly for end-to-end timing.
The value yes for end-to-end timing indicates that end-to-end
timing is required for the connection.
The value no for end-to-end timing indicates that end-to-end timing
is not required for the connection.ro Enumeration .1.3.6.1.4.1.3764.1.1.30.114.9.20.7.100.1.72 |
atmIfVptVccTmClippingBbcThis attribute indicates the value of the clipping susceptibility
parameter in the broadband bearer capability (BBC) Information

atmIfVptVccTmUnshapedTransmitQueueingThis attribute indicates the unshaped transmit queuing state of the
connection.
A value of common indicates that transmit traffic is being enqueued
onto the common transmit queue for this service category.
The txQueueLength attribute indicates the current length of the
common transmit queue.
A value of fifo indicates that transmit traffic is being queued in a
first-in-first-out basis for this service category. This is similar to
common queueing, but the txQueueLength attribute indicates the
number of cells in this connection queue. A value of fifo will only
be indicated for connections on ATM IP cards with
atmServiceCategory of nrtVbr or ubr.
A value of perVc indicates that transmit traffic is being enqueued
onto a per-VC queue for this connection.
A value of notApplicable indicates that transmit traffic is being
shaped for this connection, or that unshaped transmit queuing is not
applicable for this type of connection. Transmit traffic for a shaped
connection is enqueued onto a per-VC queue, but this attribute is
only applicable for unshaped connections. Unshaped transmit

basis.ro Enumeration .1.3.6.1.4.1.3764.1.1.30.114.9.20.7.100.1.78 |
atmIfVptVccTmWeightThis attribute indicates the relative weight of this unshaped
connection. Connections with a larger weight get a larger proportion
of the link bandwidth, or in the case of standard Vpt Vccs, the Vpt
bandwidth.
For all but standard Vpt Vccs, the default connection weight is
determined by the weight policy for a service category and the
traffic descriptor for a connection. For standard Vpt Vccs, the
default connection weight is determined by the Vcc's service
category.
For CQC-based ATM cards, this attribute is not applicable and is
not displayed.
A value from 1 to 4095 indicates an actual weight. The value
upToQueueLimit indicates that the weight of a connection is up to
the transmit queue limit for this connection. upToQueueLimit is
used with common (first-in-first-out) queueing.

atmIfVptVccTmUsageParameterControlThis attribute indicates the UPC state of the connection.
A value of notApplicable indicates that UPC is not applicable or not
supported for the connection. This is the case:
- when the connection's rxTrafficDescType is 1 or 2.
- for standard Vpt Vccs and basic Vpts.
A value of notApplicable is set regardless of whether UPC is
disabled or enabled in provisioning data.
A value of disabled indicates that UPC is applicable and supported
for the type of connection but has been turned off in the
provisioning data.
A value of enforced indicates that UPC is actively checking
conformance for the connection and is discarding or tagging cells
which do not conform to the connection traffic contract. The traffic
descriptor parameters used for UPC conformance are reflected in
the rxTrafficDescParms of the connection. On ATM IP cards, the
counts of UPC violations are visible in the Vcc, Vpc, or Vpt
rxUpcViolationsOnEnforcer1 or rxUpcViolationsOnEnforcer2
attributes.
ATM IP cards provide the ability to monitor UPC violations without
tagging or discarding. A value of monitored indicates that UPC is
actively checking conformance for the connection and counting the
violations, but is not discarding or tagging cells which do not
conform to the connection traffic contract. The traffic descriptor
parameters used for UPC conformance are reflected in the
rxTrafficDescParms of the connection. The counts of UPC
violations are visible in the Vcc, Vpc, or Vpt
rxUpcViolationsOnEnforcer1 or rxUpcViolationsOnEnforcer2
attributes. The value of monitored appears only on ATM IP cards.
If the atmServiceCategory for this connection indicates

atmIfVptVccTmBandwidthElasticThis attribute is only of importance for connections which are
carried on a link with a variable bandwidth. For example, the
bandwidth may be reduced in the event that one or more physical
links in the IMA group fail, such that the originally requested
bandwidth cannot be maintained. This attribute shows whether the
application (for example, Trunk) running on this connection can
continue to operate if the bandwidth is reduced. If the bandwidth is
reduced, the amount by which it is reduced is displayed in the
bandwidthReduction attribute.
A value of yes, indicates that this connection is elastic, and the
bandwidth may be reduced but the connection is not released.
A value of no indicates that the bandwidth for this connection is not
reduced in the event of link bandwidth reduction. However, this
connection may be released based on its holdingPriority.
Bandwidth elasticity has no effect for connections which have an
equivalent cell rate (ECR) of zero.

atmIfVptVccTmBandwidthReductionThis attribute shows the amount by which the bandwidth has been
reduced for this connection. This value is non-zero only for
connections which have bandwidthElastic displayed as yes, and
which are also operating in a reduced bandwidth mode. This is
typically the case for selected connections running over an IMA
link. This attribute takes a value from 0 (no reduction) up to the
ECR. For all connections which are running at their full allocated
bandwidth, bwReduction has the value 0. Connections which have
been reduced in allocated bandwidth have a positive number for this
attribute. The bwReduction may be subtracted from the ECR (which
is displayed as txTrafficDescParm 5) to determine the actual

atmIfVptVccTmAbrConnectionTypeThis attribute indicates the type of ABR behavior which is in effect
at this connection. This attribute is only applicable if the
atmServiceCategory attribute is availableBitRate. If the
atmServiceCategory attribute is not availableBitRate, or if the
connection is not active, this attribute value is displayed as
notApplicable.
For CQC-based ATM cards, the only possible values are
notApplicable, efciSwitch or nonAbrInterworking. In EFCI
marking mode, the Explicit Forward Congestion Indication (EFCI)
field in the data cell headers is used to indicate transmit queue
congestion.
For ATM IP cards, if the connectionPointType is displayed as
connectionEndPoint, this attribute has the value sourceDest. In this
mode, the ABR Source and Destination behavior is in effect at this
connection. This attribute is also sourceDest in the case where the
next hop connection is specified as nonAbrInterworking. The next
hop connection is the Vcc or Vpc identified by the nextHop attribute
of the Nrp or Rp component.
If the connectionPointType is not connectionEndPoint, the value of
this attribute depends upon the abrConnectionType provisioning
and the card type to which the traffic is forwarded on the backplane.
The default abrConnectionType is provisioned at the CA Abr
abrConnectionType attribute, and may be overridden for a
provisioned connection in the Vcd Tm abrConnectionType or Vpd
Tm abrConnectionType attribute. If the CA Abr abrConnectionType
attribute is virtualSourceDest at either one of the two connection
points, and if both the connection points are defined on ATM IP
cards, virtual source and destination behavior is applied to the
connection. In this instance, the attribute displays the value
virtualSourceDest.
This attribute has the value erSwitch if ABR explicit rate
functionality is in effect at this connection. In this mode, the switch
may modify the Explicit Rate (ER) field of backward Resource
Management (RM) cells to indicate the status of congestion at this
connection point.
This attribute has the value nonAbrInterworking in the case where
this connection point is functioning as an SPVC origin for an ABR
connection where the link side of this connection is configured as a
non-ABR ATM service category. This means that there are no RM
cells on the link side of this connection, and that the next hop
connection point is performing as an ABR sourceDest.ro Enumeration .1.3.6.1.4.1.3764.1.1.30.114.9.20.7.100.1.110 |
atmIfVptVccTmTxTdpTableThis attribute is a vector of five transmit traffic parameters whose

The values of peak cell rate (PCR), sustained cell rate (SCR),
Minimum Cell Rate (MCR), actual cell rate (ACR), explicit rate
(ER), equivalent cell rate (ECR), and actual shaping rate are
expressed in cell/s. Maximum burst size (MBS) is expressed in
cells. CDVT is expressed in microseconds.
When txTrafficDescType is 1 or 2, parameters 1 through 5 are
unused.
In this description, PCR is the greater of either the PCR or the
requested shaping rate (parameter 1 or parameter 5) specified in the
txTrafficDescParm attribute under the Vcd Tm or Vpd Tm
component.
When txTrafficDescType is 3, parameter 1 represents the PCR for
CLP equal to 0 or 1 traffic; parameters 2 and 3 are unused.

CLP equal to 0 and 1 traffic; parameter 2 represents the PCR for
CLP equal to 0 traffic with cell discard.
When txTrafficDescType is 5, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic; parameter 2 represents the PCR for
CLP equal to 0 traffic with cell tagging.
When txTrafficDescType is 6, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic; parameter 2 represents the SCR for
CLP equal to 0 and 1 traffic; parameter 3 represents the MBS for
CLP equal to 0 and 1 traffic.
When txTrafficDescType is 7, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic; parameter 2 represents the SCR for
CLP equal to 0 traffic with cell discard; parameter 3 represents the
MBS for CLP equal to 0 traffic.
When txTrafficDescType is 8, parameter 1 represents the PCR for
CLP equal to 0 and 1 traffic; parameter 2 represents the SCR for
CLP equal to 0 traffic with cell tagging; parameter 3 represents the
MBS for CLP equal to 0 traffic.
When txTrafficDescType is 3, 4, 5, 6, 7, or 8, parameter 4 reflects
the actual shaping rate in cell/s for this connection. For CQC-based
ATM cards, the set of available shaping rates is based on the
number of interfaces doing shaping (attribute
perVcQueueInterfaces), and the shapingScalingFactor attribute of
the Arc Cqc Override component. A rate of zero (0) indicates that
shaping is not performed, or that the interface is down.
When txTrafficDescType is 9, parameter 1 represents the PCR;
parameter 2 represents the Cell Delay Variation Toleration (CDVT);
parameter 3 represents the Minimum Cell Rate (MCR); the meaning
of parameter 4 depends upon the value of the abrConnectionType
attribute. if abrConnectionType is sourceDest or
virtualSourceDest, parameter 4 represents the Allowed Cell Rate
(ACR); If abrConnectionType is erSwitch, parameter 4 represents
the Explicit Rate (ER); and if abrConnectionType is efciSwitch,
parameter 4 reflects the actual shaping rate in cell/s for this
connection.
When txTrafficDescType is 3, 4, 5, 6, 7, 8, or 9, parameter 5 reflects
the equivalent cell rate in cell/s for this connection as determined by
the Connection Admission Control (CAC) algorithm. The
equivalent cell rate is useful in determining the admission
characteristics of this connection. SEQUENCE OF AtmIfVptVccTmTxTdpEntry .1.3.6.1.4.1.3764.1.1.30.114.9.20.7.451 |

MBS for CLP equal to 0 traffic; parameter 4 represents the CDVT.
When rxTrafficDescType is 9, parameter 1 represents the PCR;
parameter 2 represents CDVT; parameter 3 represents the MCR;
parameter 4 indicates the instantaneous rate at which dynamic
generic cell rate algorithm (DGCRA) is in effect.
If upc is disabled for this connection, the values of PCR, SCR,
MBS and CDVT are the provisioned parameters.
If upc is enabled, the values of PCR, SCR, MBS, and CDVT are
exactly the values used by the usage parameter control hardware in
policing the arriving traffic. These may vary slightly from the
provisioned values due to granularity of the hardware. In the case
where the PCR is equal to the SCR, the effective MBS is zero. SEQUENCE OF AtmIfVptVccTmRxTdpEntry .1.3.6.1.4.1.3764.1.1.30.114.9.20.7.453 |

atmIfVptVccRxOamCellCongestionStateThis attribute contains the current state of the receive side OAM cell
congestion for this connection. Its value reflects whether the rate of
received OAM cells for this connection is below a specified
threshold. The connection maintains a count of the number of OAM
cells which are terminated per second. Once that count exceeds the
specified threshold, extraction of all OAM cells for this connection
is disabled for a period of one minute. This is a congestion
management mechanism to prevent the processor from being
overloaded with handling OAM cells for a particular connection.
This mechanism ensures that tasks, such as trunks obtain enough
processor cycles to remain in service, and are not adversely affected
by excessive rate of OAM cells on a particular connection.
The value is good when the rate of received OAM cells is less than
the allowed threshold.
The value is bad when the arrival rate has exceeded the allowed
threshold. It remains bad for one minute, before returning to good
again. During this timeout, extraction of all OAM cells is disabled
for this connection. As a result, other loopback failure conditions
may occur.
The value is unknown when the application has not yet begun to
use this connection. An example is the Test component before a test
has been started.
Each type of OAM cell is counted separately. The threshold for AIS
cells is three cells per second. If more than three AIS cells are
received within a one second interval, this attribute is set to bad.
The threshold for RDI cells and each loopback type is also three,
but the threshold for trace cells is 250 per second.
The state of this attribute has no direct effect on the value of the

atmIfVptVccAtmServiceCategoryThis attribute is HISTORICAL. Please refer to the attribute of the
same name in the group AtmTmOper.
This attribute indicates the ATM service category used for traffic in
both directions of the connection.
The constantBitRate service category is intended for real time
applications, that is, those requiring tightly constrained delay and
delay variation, as would be appropriate for voice and video
applications. The consistent availability of a fixed quantity of
bandwidth is considered appropriate for CBR service. Cells which
are delayed beyond the value specified by Cell Transfer Delay are
assumed to have significantly reduced value of the application.
The rtVariableBitRate service category is intended for real time
applications; that is those requiring tightly constrained delay and
delay variation, as would be appropriate for voice and video
applications. Sources are expected to transmit at a rate which varies
with time. Equivalently, the source can be described as 'bursty'.
Cells which are delayed beyond the value specified by Cell Transfer
Delay are assumed to be of significantly reduced value to the
application. Real time VBR service may support statistical
multiplexing of real time sources.
The nrtVariableBitRate service category is intended for non-real
time applications which have bursty traffic characteristics and which
can be characterized in terms of a PCR, SCR, and MBS. For those
cells which are transferred within the traffic contract, the application
expects a low cell loss ratio. For all connections, it expects a bound
on the mean cell transfer delay. Non-real time VBR service may
support statistical multiplexing of connections.
The unspecifiedBitRate service is intended for non-real time
applications, that is those not requiring tightly constrained delay
and delay variation. UBR sources are expected to be bursty. UBR
service supports a high degree of statistical multiplexing among
sources. UBR service does not specify traffic related service
guarantees. No numerical commitments are made with respect to
the cell loss ratio experienced by a UBR connection, or as to the
cell transfer delay experienced by cells on the connection.roobsolete Enumeration .1.3.6.1.4.1.3764.1.1.30.114.9.20.130.1.62 |

This attribute indicates the bearer capability for this connection.
Class a service is a connection-oriented, constant bit rate ATM
transport service. Class a service has end to end timing
requirements and may require stringent cell loss, cell delay and cell
delay variation performance.When a is displayed, the user is
requesting more than an ATM only service. The network may look
at the AAL to provide interworking based upon its contents.
Class c service is a connection-oriented, variable bit rate ATM
transport service. Class c service has no end-to-end timing
requirements.When c is displayed, the user is requesting more than
an ATM only service. The network interworking function may look
at the AAL and provide service based on it.
Class x service is a connection-oriented ATM transport service
where the AAL, trafficType (cbr or vbr) and timing requirements
are user defined (that is, transparent to the network). When the
value of this attribute is x, the user is requesting an ATM only
service from the network. In this case, the network shall not process
any higher layer protocol.
Class vp service is used to indicate a transparent VP service when
the user is requesting an ATM only service from the network. In this
case, the network does not process any higher layer protocol. This
service differs from class x service in that with the class vp service
both the VCI field (except for VCI values 0, 3, 4, and 6 through 15)
and Payload Type field are transported transparently by the network.

three elements reflect the settings of the first three elements of the
txTrafficDescParm attribute in the AtmTrafficProv group.
When txTrafficDescType is 1 or 2, parameters 1 through 5 are
unused.
In this description, PCR is the greater of either the PCR or the

When txTrafficDescType is 3, 4, 5, 6, 7 or 8, parameter 4 reflects
the actual shaping rate in cell/s for this connection. This rate is one
of the set of available shaping rates for this type of ATM-FP, based
on the number of interfaces doing shaping (attribute
perVcQueueInterfaces), the provisioned cell rate, the
shapingScalingFactor attribute of the AtmResourceControl
component, and whether traffic shaping is enabled. A rate of zero
(0) indicates that shaping is not performed.
When txTrafficDescType is 3, 4, 5, 6, 7 or 8, parameter 5 reflects
the equivalent cell rate in cell/s for this connection as determined by
the Connection Admission Control (CAC) algorithm. The
equivalent cell rate is useful in determining the admission

atmIfVptVccTxQThreshTableThis attribute is HISTORICAL. Please refer to the attribute of the
same name in the group AtmTmOper.
This attribute indicates the queue limit and the discard thresholds
for the transmit queue of this connection.
The first element indicates the queue limit. Depending upon the
atmServiceCategory of the connection, the provisioned value of the
transmit queue limit is derived from the txQueueLimit attribute
under one of the subcomponents of the AtmIf CA component. If the
connection has traffic shaping disabled, then this attribute relates to
the common queue. If traffic shaping is enabled, then this attribute
relates to the per-VC queue.
The second element is the threshold that marks the transition from
congestion state 1 to congestion state 0. This is the threshold at
which traffic with discard priority (DP) = 1 is discarded. This
threshold is set approximately at 90 percent of the first parameter,
the operational queue limit.
The third element is the threshold that marks the transition from
congestion state 2 to congestion state 1. This is the threshold at
which traffic with DP = 2 is discarded. This threshold is set
approximately at 75 percent of the first parameter, the operational
queue limit.
The fourth element is the threshold that marks the transition from
congestion state 3 to congestion state 2. This is the threshold at
which traffic with DP = 3 is discarded. This threshold is set
approximately at 35 percent of the first parameter, the operational

management mechanism to prevent the processor from being
overloaded with handling OAM cells for a particular connection.
This mechanism ensures that tasks, such as trunks obtain enough
processor cycles to remain in service, and are not adversely affected
by excessive rate of OAM cells on a particular connection.
The value is good when the rate of received OAM cells is less than
the allowed threshold.
The value is bad when the arrival rate has exceeded the allowed
threshold. It remains bad for one minute, before returning to good
again. During this timeout, extraction of all OAM cells is disabled
for this connection. As a result, other loopback failure conditions
may occur.
The value is unknown when the application has not yet begun to
use this connection. An example is the Test component before a test
has been started.
Each type of OAM cell is counted separately. The threshold for AIS
cells is three cells per second. If more than three AIS cells are
received within a one second interval, this attribute is set to bad.
The threshold for RDI cells and each loopback type is also three,
but the threshold for trace cells is 250 per second.
The state of this attribute has no direct effect on the value of the

atmIfVptAtmServiceCategoryThis attribute is HISTORICAL. Please refer to the attribute of the
same name in the group AtmTmOper.
This attribute indicates the ATM service category used for traffic in
both directions of the connection.
The constantBitRate service category is intended for real time
applications, that is, those requiring tightly constrained delay and
delay variation, as would be appropriate for voice and video
applications. The consistent availability of a fixed quantity of
bandwidth is considered appropriate for CBR service. Cells which
are delayed beyond the value specified by Cell Transfer Delay are
assumed to have significantly reduced value of the application.
The rtVariableBitRate service category is intended for real time
applications; that is those requiring tightly constrained delay and
delay variation, as would be appropriate for voice and video
applications. Sources are expected to transmit at a rate which varies
with time. Equivalently, the source can be described as 'bursty'.
Cells which are delayed beyond the value specified by Cell Transfer
Delay are assumed to be of significantly reduced value to the
application. Real time VBR service may support statistical
multiplexing of real time sources.
The nrtVariableBitRate service category is intended for non-real
time applications which have bursty traffic characteristics and which
can be characterized in terms of a PCR, SCR, and MBS. For those
cells which are transferred within the traffic contract, the application
expects a low cell loss ratio. For all connections, it expects a bound
on the mean cell transfer delay. Non-real time VBR service may
support statistical multiplexing of connections.
The unspecifiedBitRate service is intended for non-real time
applications, that is those not requiring tightly constrained delay
and delay variation. UBR sources are expected to be bursty. UBR
service supports a high degree of statistical multiplexing among
sources. UBR service does not specify traffic related service
guarantees. No numerical commitments are made with respect to
the cell loss ratio experienced by a UBR connection, or as to the
cell transfer delay experienced by cells on the connection.roobsolete Enumeration .1.3.6.1.4.1.3764.1.1.30.114.9.130.1.62 |
atmIfVptTrafficShapingThis attribute is HISTORICAL. Please refer to the attribute of the

when the atmServiceCategory is constantBitRate, or when the
txTrafficDescType is 1 or 2. In these cases, the value of
notApplicable is set regardless of whether traffic shaping is enabled
or disabled in the provisioning data.
A value of disabled indicates that traffic shaping is applicable and
supported for the type of connection but has been turned off in the
provisioning data.
A value of enabled indicates that traffic shaping is applicable and
supported for the type of connection and has been turned on in the
provisioning data. This is the only case that indicates that traffic

atmIfVptBearerClassBbcThis attribute is HISTORICAL. Please refer to the attribute of the
same name in the group AtmTmOper.
This attribute indicates the bearer capability for this connection.
Class a service is a connection-oriented, constant bit rate ATM
transport service. Class a service has end to end timing
requirements and may require stringent cell loss, cell delay and cell
delay variation performance.When a is displayed, the user is
requesting more than an ATM only service. The network may look
at the AAL to provide interworking based upon its contents.
Class c service is a connection-oriented, variable bit rate ATM
transport service. Class c service has no end-to-end timing
requirements.When c is displayed, the user is requesting more than
an ATM only service. The network interworking function may look
at the AAL and provide service based on it.
Class x service is a connection-oriented ATM transport service
where the AAL, trafficType (cbr or vbr) and timing requirements
are user defined (that is, transparent to the network). When the
value of this attribute is x, the user is requesting an ATM only
service from the network. In this case, the network shall not process
any higher layer protocol.
Class vp service is used to indicate a transparent VP service when
the user is requesting an ATM only service from the network. In this
case, the network does not process any higher layer protocol. This
service differs from class x service in that with the class vp service
both the VCI field (except for VCI values 0, 3, 4, and 6 through 15)
and Payload Type field are transported transparently by the network.

When txTrafficDescType is 3, 4, 5, 6, 7 or 8, parameter 4 reflects
the actual shaping rate in cell/s for this connection. This rate is one
of the set of available shaping rates for this type of ATM-FP, based
on the number of interfaces doing shaping (attribute
perVcQueueInterfaces), the provisioned cell rate, the
shapingScalingFactor attribute of the AtmResourceControl
component, and whether traffic shaping is enabled. A rate of zero
(0) indicates that shaping is not performed.
When txTrafficDescType is 3, 4, 5, 6, 7 or 8, parameter 5 reflects
the equivalent cell rate in cell/s for this connection as determined by
the Connection Admission Control (CAC) algorithm. The
equivalent cell rate is useful in determining the admission

associated with this EmissionPriority. A minimum bandwidth
guarantee is designed to prevent starvation of traffic at this EP by
traffic at higher EPs. Minimum bandwidth guarantees only operate
for EPs within the guaranteed bandwidth range 2 through 7.
The minimum bandwidth guarantee specified is a percentage of the
bandwidth which remains after all traffic at EP 0 and EP 1 is served.
For example, if EP 0 and EP 1 traffic consumes 20% of link
bandwidth, the minimum bandwidth guarantee applies to the
remaining 80% of the link bandwidth. A minimum bandwidth
guarantee of 2% would actually result in this EP getting 2% of 80%
(total 1.6%) of the link bandwidth.
The sum of minimumBandwidthGuarantee values for all Eps under
an AtmIf must not exceed 100%.
The value priority specifies that this Ep gets the bandwidth
guarantee which is applicable based on the hierarchy of emission
priorities. In this case, there is no minimum bandwidth guarantee.
A value between 1 and 49 specifies that from 1% to 49% of the
remaining link bandwidth is reserved for traffic at this EP. Given a
value n of minimumBandwidthGuarantee, then for n% of transmit
cell opportunities in the guaranteed bandwidth range, this EP get
first opportunity to send a cell. If this EP uses less than n% of the
link bandwidth, the extra opportunities are allocated in priority. Due
to scheduling and cell arrival times, traffic at this EP may not
necessarily achieve full utilization of its minimum bandwidth
guarantee.
When specifying a value for minimumBandwidthGuarantee,
consider the effect on cell delay variation (CDV) of traffic which
would normally be of higher priority. For example, if RtVbr service
category traffic is assigned to Ep/2 and Ubr traffic is assigned on
Ep/7 where Ep/7 has a minimumBandwidthGuarantee of 25%, there
can be a large impact on CDV of the RtVbr traffic. Traffic of the
Cbr or RtVbr service category which is sensitive to CDV and is of
known volume, can be assigned on EP 0 or EP 1 which are
independent of the effects of minimum bandwidth guarantee.

atmIfCustomerIdentifierThis attribute holds the Customer Identifier (CID).
Every component has a CID. If a component has a cid attribute, the
component's CID is the provisioned value of that attribute;
otherwise the component inherits the CID of its parent. The top-
level component has a CID of 0.
Every operator session also has a CID, which is the CID
provisioned for the operator's user ID. An operator will see only the
stream data for components having a matching CID. Also, the
operator will be allowed to issue commands for only those
components which have a matching CID.
An operator CID of 0 is used to identify the Network Manager
(referred to as 'NetMan' in DPN). This CID matches the CID of
any component. Values 1 to 8191 inclusive (equivalent to 'basic
CIDs' in DPN) may be assigned to specific customers.rw Unsigned32 (0 | 1..8191) .1.3.6.1.4.1.3764.1.1.30.114.100.1.1 |

atmIfTrafficShapingIt is migrated in P6.0 to a combination of the trafficShaping
attributes and the emissionPriority attributes under each ATM
service category component of the AtmIf CA.
This attribute defines whether traffic shaping is enabled or disabled
for the entire AtmIf. When this attribute is set to enabled, each
provisioned connection under the interface can be individually
provisioned to permit or prohibit traffic shaping. When this attribute
is set to disabled, no traffic shaping is performed on the transmit
path for any of the connections. This attribute may be set to enabled
if the interface supports shaping, as defined by the
perVcQueueInterfaces attribute in the AtmResourceControl
component. If the AtmResourceControl component does not exist,
this attribute may not be set to enabled.rwobsolete Enumeration .1.3.6.1.4.1.3764.1.1.30.114.110.1.60 |
atmIfUnshapedTransmitQueueingIt is migrated in P6.0 to the attributes of the same name under each
ATM service category component of the AtmIf CA.
This attribute applies only for unshaped VCC and VPC
connections. This attribute defines the transmit queueing method for
all unshaped connections under this AtmIf. Per-VC queueing means
that unshaped connections are treated with the same fairness as
shaped queues in the transmit round-robin scheduling. The
alternative to per-VC queueing is to use the common queue for a
particular service category (medium or low priority). The common
queue is only counted as one queue in the transmit round-robin
scheduling. Thus, if there are multiple connections which are
destined for the common queue, they are not fairly allocated a
portion of the transmit bandwidth compared to shaped connections.
When this attribute is set to perVc, any unshaped connection is
allocated its own per-VC queue, and is treated with the same
fairness as any shaped connections. Per-VC queues have a
maximum rate of 58,962 cell/s (25 Mbit/s) in a multi-port shaping
configuration. Per-VC queues also have their own congestion
control level. This means that total number of cell/frame blocks
allocated for several per-VC queues are higher than would be
allowed on the common queue. This can be an advantage in
reducing cell loss due to queue congestion. This attribute may only
be set to perVc if the interface supports per-VC queueing, (specified
by the perVcQueueInterfaces attribute in the AtmResourceControl
component).
When this attribute is set to common, any unshaped connection is
destined for the common queue. The common queue has one set of
congestion control levels for all cells enqueued on it. The common
queue is only allocated one queue position when scheduling which
queue to transmit from. Due to the possibility of unfairness, this
value is only recommended in cases where the configuration cannot
otherwise achieve full link utilization.
When this attribute is set to autoConfigure and the interface
support per-VC queueing (specified by the perVcQueueInterfaces
attribute in the AtmResourceControl component) per-VC queueing
is enabled for all unshaped connections. Otherwise, the common
queue is used. The unshapedTransmitQueueingOper attribute
indicates whether the transmit queueing is perVc or common.rwobsolete Enumeration .1.3.6.1.4.1.3764.1.1.30.114.110.1.70 |
atmIfUsageParameterControlIt is migrated in P6.0 to the attributes of the same name under each
ATM service category component of the AtmIf CA.
This attribute defines whether usage parameter control (UPC) is
enabled or disabled for receive traffic for Vcc and Vpc connections
for this entire AtmIf. When this attribute is set to enabled, each
provisioned connection under the interface can be individually
provisioned to enforce or ignore UPC. When this attribute is set to
disabled, UPC cannot be enabled on the receive path for any of the
connections.rwobsolete Enumeration .1.3.6.1.4.1.3764.1.1.30.114.110.1.80 |
atmIfMaxVpiBitsThis attribute specifies the maximum number of VPI bits that may
be active for this AtmIf. These bits start at the least significant bit
position and are contiguous. In general, the maximum VPI which
may be used on the interface is 2**maxVpiBits - 1. The value of the
remaining (inactive) VPI bits is ignored on cells received from the
link.
If the AtmIf is linked to a LogicalProcessor of cardType
3pOC3MmAtm, 3pOC3SmAtm, 3pE3Atm, 3pDS3Atm, 3pE1Atm,
3pDS1Atm, or 2pJ6MAtm, the value of this attribute must be 8. The
maximum VPI supported on these card types is 255.
If the AtmIf is linked to a LogicalProcessor of any other cardType,
the value of this attribute may be 8 or 12. The maximum VPI
supported on these card types is 4095. An exception is that
cardType 8pE1Atm and 8pDS1Atm do not support VPI 4095; the
maximum VPI on these card types is 4094.
If a Uni or an Iisp component is present directly under the AtmIf,

atmIfRemoteAtmInterfaceLabelThis attribute specifies a unique indication of the remote ATM
service or interface component connected to this one. The value of
this attribute can be used by network management applications to
discover the network's ATM topology from its configuration
information.
The syntax of the value, such as component ID, address, or other
numerical identifier, must follow the conventions of the network
management platform. In absence of such convention or platform,
the value should be left empty.
The value is only stored by the module. It is neither validated nor
used to perform any form of remote connectivity validation.rw AsciiString .1.3.6.1.4.1.3764.1.1.30.114.110.1.90 |
atmIfTxCellMemoryThis attribute specifies the percentage of total transmit cell memory
which is available for use by connections under this AtmIf. This
attribute is not applicable, and is ignored for CQC-based ATM FPs.
Transmit cell memory is used for storing ATM cells to be
transmitted by connections under this AtmIf. It includes all cells in
connections at the nrt-VBR or UBR service category. It includes
cells in CBR or rt-VBR connections which are doing per-VC
queueing. It does not include cells in CBR or rt-VBR connections
which are allocated from the dedicated buffer for CBR common
queuing or rt-VBR common queuing.
If the value of this attribute is specified as 100, connections under
this AtmIf may use up to 100% of the total transmit cell memory. If
this attribute is specified as an amount less than 100, then only that
percentage of the total transmit cell memory may be used by
connections under this AtmIf. The minimum value for this attribute
is 1% since some cell memory is always required for connections.
For 3pDs3Atm2 and 3pE3Atm2 card types, the total cell memory
displayed in Lp/x Eng Arc Aqm/0 txCellMemoryThreshold 0 is
shared across all three interfaces for the card. Specifying a value of
100% enables complete overbooking of the total transmit cell
memory by the three AtmIf's on this card. On a DS3 or E3 card,
specifying values for this attribute such that each value is less than
100% but the sum for the three AtmIf's is more than 100% enables
partial overbooking of the transmit cell memory. Specifying values
for this attribute under the three AtmIf's where the sum of these
attributes adds up to exactly 100%, ensures that each AtmIf has a
dedicated pool of transmit cells with no overbooking. Specifying
values for this attribute under the three AtmIf's where the sum of
these attributes adds up to less than 100%, restricts the total size of
the free list. This can be used to ensure the functioning of port
aggregation even with a small number of connections.
For 2pOc3MmAtm2 and 2pOC3SmAtm2 card types, the cell
memory displayed in Lp/x Eng Arc Aqm/0 txCellMemoryThreshold
0 is allocated to the first interface for the card. Cell memory
displayed in Lp/x Eng Arc Aqm/1 txCellMemoryThreshold 0 is
allocated to the second interface for the card. Specifying an amount
less than 100% restricts the total size of the free list. This can be
used to ensure the functioning of port aggregation even with a small
number of connections.rw Unsigned32 .1.3.6.1.4.1.3764.1.1.30.114.110.1.91 |
atmIfFaultHoldOffTimeThis attribute specifies the delay before faults detected at the VP
layer are propagated to the VC layer, and thus to the application
using the connection.
If the value is 0 (zero), applications using a VirtualPathTerminator
are immediately notified of faults detected by the VP. Using this
value allows these applications to be advised of faults without
requiring loopbacks on each Vcc. Typically, the application goes out
of service when advised of a fault.
If the value is infinity, applications are not notified of VP layer
faults. Using this value allows the applications to survive transient
VP layer fault conditions.

displayed on CQC-based ATM FPs.
This attribute indicates which txCellMemoryThreshold corresponds
to the current value of txCellMemoryUsage. The congestion state is
used to determine if cells of a particular discard priority (DP) are
discarded before being queued for transmit.
The congestion state of transmit cell memory is indicated by a
numeric value ranging from 3 to 0. When transmit cell memory is in
congestion state 'x', traffic with DP > 'x' is discarded before
transmit. Traffic with DP < 'x' may be queued for transmit,
depending on the congestion level of the connection transmit queue.
Traffic with DP = 'x' may be either queued or discarded depending
on how close the value of txCellMemoryUsage is to the next
threshold as displayed in txCellMemoryThreshold. For example,
CLP1 traffic is queued until the value indicated by
txCellMemoryUsage equals the value indicated in
txCellMemoryThreshold 3. At that point, CLP1 traffic is discarded.ro Gauge32 .1.3.6.1.4.1.3764.1.1.30.114.140.1.2 |

atmIfTxCellMemoryThresholdTableThis attribute is a vector which indicates the size and three discard
thresholds for transmit cell memory for this AtmIf. This attribute is
not applicable, and is not displayed on CQC-based ATM FPs.
Transmit cell memory used for storing ATM cells to be transmitted
by connections under this AtmIf. It includes all cells in connections
at the nrt-VBR or UBR service category. It includes cells in CBR or
rt-VBR connections which are doing per-VC queueing. It does not
include cells in CBR or rt-VBR connections which are allocated
from the dedicated buffer for CBR common queuing or rt-VBR
common queuing.
The first value indicates the transmit cell memory size. It is the
multiplication of the Lp/x Eng Arc Aqm/y txCellMemoryThreshold 0
attribute by the txCellMemoryPercentage attribute of this AtmIf.
The current value of txCellMemoryUsage together with the vector
of values in txCellMemoryThreshold determines the
txCellMemoryCongestionState. The congestion state determines
whether cells of a given discard priority (DP) are discarded or
queued for transmit.
When the txCellMemoryUsage attribute is between threshold 0 and
threshold 1, the txCellMemoryCongestionState indicates the value
0. In congestion state 0, traffic with DP > 0 is discarded. Threshold
1 is set approximately at 90 percent of threshold 0, the total transmit
cell memory size.
When the txCellMemoryUsage attribute is between threshold 1 and
threshold 2, the txCellMemoryCongestionState indicates the value
1. In congestion state 1, traffic with DP > 1 is discarded. Threshold
2 is set approximately at 85 percent of threshold 0, the total transmit
cell memory size.
When the txCellMemoryUsage attribute is between threshold 2 and
threshold 3, the txCellMemoryCongestionState indicates the value
2. In congestion state 2, traffic with DP > 2 is discarded. Threshold
3 is set approximately at 75 percent of threshold 0, the total transmit
cell memory size.
When the txCellMemoryUsage attribute is below threshold 3, the
txCellMemoryCongestionState indicates the value 3. In congestion
state 3, traffic with DP=3 is queued. SEQUENCE OF AtmIfTxCellMemoryThresholdEntry .1.3.6.1.4.1.3764.1.1.30.114.441 |
