ieee8021CnCpDiscardedFrames objects on any Port or priority in
this same component are incremented.
Discontinuities in the value of this counter can occur
at re-initialization of the management system, and at
other times as indicated by the value of
ifCounterDiscontinuityTime object of the associated
interface (if any).ro Counter64 UNITS "frames" .ieee8021CnMib.1.1.1.4 |
ieee8021CnErroredPortTableThere is one Errored Port Table per Bridge component or end
station. It permits the retrieval of information about which
interfaces have congestion notification configuration errors,

ieee8021CnCompntPriTableEach row in this table supplies default values for one
Congestion Notification Priority Value for a whole Bridge
component or end station.
Creating a row in this table makes the priority value of
ieee8021CnComPriPriority a
Congestion Notification Priority Value.
Deleting a row in this table makes the value in the deleted
ieee8021CnComPriPriority no longer a
Congestion Notification Priority Value.
A system SHALL NOT allow eight rows in this table

in this ieee8021CnCompntPriEntry applies. If the system is
not a Bridge, or if only one component is present in the
Bridge, then this variable (index) MUST be equal to 1. IEEE8021PbbComponentIdentifier (IEEE8021-TC-MIB) .ieee8021CnMib.1.3.1.1 |
ieee8021CnComPriPriorityThe Congestion Notification Priority Value for which this
row supplies default values. IEEE8021PriorityValue (IEEE8021-TC-MIB) .ieee8021CnMib.1.3.1.2 |
ieee8021CnComPriDefModeChoiceSpecifies how the default CND defense mode and alternate
priority for this Congestion Notification Priority Value on all
ports on this Bridge component or end station are to be chosen,
either:
cpcAdmin(1) Default CND defense mode is chosen by
ieee8021CnComPriAdminDefenseMode, and alternate
priority by ieee8021CnComPriAlternatePriority.
cpcAuto(2) Default CND defense mode is chosen by

contains the value cpcAuto (2).
The value of this object is the next lower priority value
than this row's ieee8021CnComPriPriority that is not a CNPV,
or the next higher non-CNPV, if all lower values are CNPVs.
The value of this object, and any consequent priority
regeneration, is automatically updated by the managed system
whenever a row in the ieee8021CnCompntPriTable is created or
deleted. The value of this object is not dependent upon
whether congestion notification is enabled or disabled for any
priority or for the whole Bridge component or end station; it
depends only upon whether the ieee8021CnCompntPriTable row
exists.ro IEEE8021PriorityValue (IEEE8021-TC-MIB) .ieee8021CnMib.1.3.1.5 |

ieee8021CnComPriRowStatusThis object indicates the status of an entry, and is used
to create/delete entries.
A system SHALL NOT permit eight ieee8021CnComPriRowStatus
objects, all with the same value of ieee8021CnComPriComponentId,

Congestion Notification Priority Value (CNPV).
Creating an entry in ieee8021CnCompntPriTable creates this
entry, with the default values, on all ports in the Bridge
component or end station. Deleting an entry in
ieee8021CnCompntPriTable deletes this ieee8021CnCompntPriEntry
on all ports in the Bridge component or end station.

Congestion Notification TLV, either:
cnlNone(1) No LLDP Congestion Notification TLV is to
carry Per-priority CNPV indicators or
Per-priority Ready indicators on this Port
for this priority.
cnlAdmin(2) ieee8021CnPortPriLldpInstanceSelector
governs which LLDP instance is to carry
Per-priority CNPV indicators and
Per-priority Ready indicators for this
priority in its Congestion Notification TLV

ieee8021CnPortPriAlternatePriorityThe Congestion Notification Priority Value to which an
incoming frame is to be mapped, in spite of what the
Priority Regereration Table says, if 1) Congestion
Notification is enabled and 2) the port is acting in the
cptEdge (4) CND defense mode.

contains the value cpcAdmin (1).rw IEEE8021PriorityValue (IEEE8021-TC-MIB) .ieee8021CnMib.1.4.1.9 |
ieee8021CnCpTableEach row in this table supplies values for one
Congestion Point (CP).
This table is indexed by component, port (interface), and
an arbitrary CP index. This arbitrary CP index is not
necessarily the Congestion Point Identifier (CPID) carried in
Congestion Notification Messages (CNMs).
Creating an entry in ieee8021CnCompntPriTable can create an
entry in this table, with the default values, on all ports in
the Bridge component or end station. Because more than one
Congestion Notification Priority Value (CNPV) can flow
through a single CP, the creation of an entry in
ieee8021CnCompntPriTable does not necessarily create a new
entry in this table. An end station can have more than one
CP for the same CNPV, so creating an entry in
ieee8021CnCompntPriTable can create multiple entries in this
table.
Because each port in a Bridge component or end station can have
a different relationship between CNPVs and CPs, the entries
created or deleted on each port can be different.
Deleting the last entry in ieee8021CnCompntPriTable for a
CNPV passing through the CP controlled by this entry deletes
the entry on some or all of the ports in the Bridge component
or end station.
Because each port in a Bridge component or end station can have
a different relationship between CNPVs and CPs, the entries
created or deleted on each port can be different.
The relationship between ieee8021CnCpIndex
values and CPs is an implementation dependent matter.

this table among the entries for the same component and
interface. In a system that supports no more than one
Congestion Point per priority per interface, ieee8021CnCpIndex

entry in this table, with the default values, on all ports
in the end station. An end station can have more than one
RP for the same Congestion Notification Priority Value

create multiple entries in this table.
Because each port in a Bridge component or end station can have
a different relationship between CNPVs and RPs, the entries
created or deleted on each port can be different.
Deleting the an entry in ieee8021CnCompntPriTable for a
CNPV passing through the RP controlled by this entry deletes
entries on some or all of the ports in the end station.
Because each port in an end station can have a
different relationship between CNPVs and RPs, the entries
created or deleted on each port can be different.
The relationship between ieee8021CnRpgIdentifier
values and RPs is an implementation dependent matter.
The contents of this table SHALL be maintained across a restart
of the system, except as noted in the description of
ieee8021CnRpgIfIndex. SEQUENCE OF Ieee8021CnRpGroupEntry .ieee8021CnMib.1.8 |
ieee8021CnRpGroupEntryAn entry in the Reaction Point table controls a group of
Reaction Points, on a port in an end station. All of the
Reaction Point controlled by this entry serve the same
Congestion Notification Priority Value. Ieee8021CnRpGroupEntry .ieee8021CnMib.1.8.1 |
ieee8021CnRpgComponentIdThe Bridge component within the system to which the information
in this ieee8021CnRpGroupEntry applies. If the system is
not a Bridge, or if only one component is present in the
Bridge, then this variable (index) MUST be equal to 1. IEEE8021PbbComponentIdentifier (IEEE8021-TC-MIB) .ieee8021CnMib.1.8.1.1 |
ieee8021CnRpgPriorityThis object indicates the lowest numerical
Congestion Notification Priority Value that this entry's
Reaction Point serves. IEEE8021PriorityValue (IEEE8021-TC-MIB) .ieee8021CnMib.1.8.1.2 |
ieee8021CnRpgIfIndexThis object indicates the interface on which the group of
Reaction Points reside.
Upon a restart of the system, the system SHALL, if necessary,
change the value of this object, and rearrange the order of the
ieee8021CnRpGroupTable, so that the value in
ieee8021CnRpgIfIndex references the row in the ifXTable with
the same value for ifAlias that it referenced before the system
restart. If no such entry exists in the ifXTable, then the
system SHALL delete the row in the ieee8021CnRpGroupTable. InterfaceIndex (IF-MIB) .ieee8021CnMib.1.8.1.3 |
ieee8021CnRpgIdentifierThis object is an arbitrary integer indexing the entries in
this table among the entries for the same interface. This
index SHOULD, where possible, be equal to the
Congestion Notification Priority Value served by this
Reaction Point. Unsigned32 .ieee8021CnMib.1.8.1.4 |
ieee8021CnRpgEnableControls the rpEnabled variable of the Reaction Point state
machines of the Reaction Points (RPs) controlled by this
entry as follows:
true(1) The rpEnabled variable for the RPs controlled by
this object are not held in the FALSE state,
thus enabling them to pay attention to received
CNMs.
false(2) The rpEnabled variable for the RPs controlled by
this object are held in the FALSE state, thus
disabling them from paying attention to received
CNMs.rw TruthValue (SNMPv2-TC) .ieee8021CnMib.1.8.1.5 |
ieee8021CnRpgTimeResetThis object controls the value for all of the state machine
variables, rpgTimeReset, used to reset the timers RpWhile.rw TimeInterval UNITS "milliseconds" .ieee8021CnMib.1.8.1.6 |
ieee8021CnRpgByteResetThis object controls the value for all of the state machine
variables, rpgByteReset, used to reset the counters
rpByteCount.rw Unsigned32 UNITS "octets" .ieee8021CnMib.1.8.1.7 |
ieee8021CnRpgThresholdThis object controls the number of times rpByteStage or
rpTimeStage can count before the

ieee8021CnRpgMaxRateThis object controls the maximum rate, in multiples of 1 Mbit/s,
at which an RP can transmit. Default value is the speed of the
port. A system SHALL support a minimim value for this object
that is no larger than 5 Mbits/s (object value 5). This rate
includes all bits consequent to transmitting the frame on the
LAN, including preamble, inter-frame gap, etc.rw Unsigned32 UNITS "Mbit/s" .ieee8021CnMib.1.8.1.9 |
ieee8021CnRpgAiRateThis object controls the transmission rate increment in the
RPR_ACTIVE_INCREASE state (rpgAiRate) in multiples of 1 Mbit/s.
This rate includes all bits consequent to transmitting the
frame on the LAN, including preamble, inter-frame gap, etc.rw Unsigned32 UNITS "Mbit/s" .ieee8021CnMib.1.8.1.10 |
ieee8021CnRpgHaiRateThis object controls the transmission rate increment in the
RPR_HYPER_INCREASE state (rpgHaiRate) in multiples of 1 Mbit/s.
This rate includes all bits consequent to transmitting the
frame on the LAN, including preamble, inter-frame gap, etc.rw Unsigned32 UNITS "Mbit/s" .ieee8021CnMib.1.8.1.11 |
ieee8021CnRpgGdThis object controls the number of bits that the value of the
Quantized Feedback field received in a CNM PDU is shifted to
the right to decrease rpTargetRate. rpgGd is thus 2 to the
negative power of this object, e.g., 7 means rpgGd = 1/128.rw Integer32 .ieee8021CnMib.1.8.1.12 |
ieee8021CnRpgMinDecFacThis object controls the minimum factor by which the current
RP transmit rate rpCurrentRate can be changed by reception
