CISCO-APS-EXT-MIB
AI MIB Summary
The CISCO-APS-EXT-MIB extends Cisco's Automatic Protection Switching (APS) management to monitor and configure path-based APS architectures and non-SONET interfaces, specifically Cisco CDL and SONET Path Terminating Equipment (PTE). It enables the tracking of protection switching states, signal degradation, and failure events for these specific interface types while excluding SONET-specific K1/K2 byte and BER threshold objects not applicable to CDL or path-based implementations.
The Cisco APS Extension MIB extends the Cisco APS MIB in order to a) support path APS architectures and b) support interfaces other than SONET (e.g. Cisco CDL).
For configuration and monitoring of APS for CDL interfaces, all objects and notifications in the Cisco APS MIB apply, with the exception of the following:
- cApsStatusK1K2Rcv and cApsStatusK1K2Trans in
cApsStatusEntry,
- cApsConfigSdBerThreshold and cApsConfigSfBerThreshold
in cApsConfigEntry,
- cApsChanStatusSignalDegrades and
cApsChanStatusSignalFailures in cApsChanStatusEntry,
- cApsStatusFEPLFs in cApsStatusEntry,
- cApsEventFEPLF.
Whenever the description of an object in the Cisco APS MIB refers to a SONET LTE interface, this applies to CDL terminating interfaces as well. CDL interfaces have ifType values other than 'sonet'.
For SONET path APS support, whenever the description of an object in the Cisco APS MIB refers to a SONET LTE interface, this applies to SONET PTE interfaces as well. SONET PTE interfaces have ifType values 'sonetPath'.

cApsExtMIBThe Cisco APS Extension MIB extends the Cisco APS MIB
in order to a) support path APS architectures and
b) support interfaces other than SONET (e.g. Cisco
CDL).
For configuration and monitoring of APS for CDL interfaces,
all objects and notifications in the Cisco APS MIB apply,
with the exception of the following:
- cApsStatusK1K2Rcv and cApsStatusK1K2Trans in
cApsStatusEntry,
- cApsConfigSdBerThreshold and cApsConfigSfBerThreshold
in cApsConfigEntry,
- cApsChanStatusSignalDegrades and
cApsChanStatusSignalFailures in cApsChanStatusEntry,
- cApsStatusFEPLFs in cApsStatusEntry,
- cApsEventFEPLF.
Whenever the description of an object in the Cisco APS MIB
refers to a SONET LTE interface, this applies to CDL
terminating interfaces as well. CDL interfaces have
ifType values other than 'sonet'.
For SONET path APS support, whenever the description of an
object in the Cisco APS MIB refers to a SONET LTE
interface, this applies to SONET PTE interfaces as well.
SONET PTE interfaces have ifType values 'sonetPath'. MODULE-IDENTITY .1.3.6.1.4.1.9.10.72 |
cApsExtMIBObjects OBJECT IDENTIFIER .1.3.6.1.4.1.9.10.72.1 |
cApsNotifiesEnableWhen this object is set to 'true', it allows the generation of
the APS-related notifications defined in the CISCO-APS-MIB.
When this object is set to 'false', it prevents the generation
of the APS-related notifications defined in the CISCO-APS-MIB.
By default, this object is set to 'false'.rw TruthValue (SNMPv2-TC) .1.3.6.1.4.1.9.10.72.1.1 |
cApsConfigExtTableThis table augments the cApsConfigTable. SEQUENCE OF CApsConfigExtEntry .1.3.6.1.4.1.9.10.72.1.2 |
cApsConfigExtEntryA conceptual row in the cApsConfigExtTable. CApsConfigExtEntry .1.3.6.1.4.1.9.10.72.1.2.1 |
cApsConfigSpanThe span (hopByHop or endToEnd) for the APS group.
hopByHop
This refers to linear APS, e.g. linear SONET APS, or hopByHop
CDL APS. In a DWDM system, an APS channel may be associated
with either an individual wavelength or an optical fiber.
All APS channels within an APS group must be of the same type.
Systems that support linear APS on an individual wavelength
basis, must assign an ifIndex to each such wavelength.
endToEnd
This refers to path APS, e.g. endToEnd CDL APS. In this
configuration, each APS channel in the APS group is associated
with an endToEnd user path. This codepoint does not apply to
interfaces with an ifType value of 'sonet'.
This object may not be modified if the associated
cApsConfigRowStatus object is equal to 'active'.rw Enumeration .1.3.6.1.4.1.9.10.72.1.2.1.1 |
cApsConfigYcableThe Y-cable configuration for the APS group associated with
user channels.
noYcable
The APS channels in the APS group are not connected to an
external Y-cable.
ycable
Two user-side interfaces (not necessarily SONET or CDL) are
connected to an external y-cable and are grouped into an APS
group for endToEnd APS. The received user signal is split
in the y-cable coupler and is received on both the interfaces.
However, only one interface must transmit toward the user at any
given time. With cApsConfigYcable set to 'ycable', the
cApsConfigSpan must be set to 'endToEnd'. There must be
only two APS channels in an APS group with cApsConfigYcable
set to 'ycable'.
ycableXconnectCommon
This refers to a configuration where two user-side interfaces
are connected to an external y-cable. The two signals received
on these interface are connected to the same cross connect in
the switch. The switch fabric selects one of the two received
signals, duplicates it, and forwards it to two network side
interfaces grouped for 1+1 linear APS. The received signal from
the network side is transmitted to only one user-side interface.
cApsConfigSpan is ignored if cApsConfigYcable is set to
'ycableXconnectCommon'. There must be only two APS channels in
an APS group with cApsConfigYcable set to
'ycableXconnectCommon'.
This object may not be modified if the associated
cApsConfigRowStatus object is equal to 'active'.
If this object is set to 'ycable' or 'ycableXconnectCommon',
the user must shut one of the two channels before setting
cApsConfigRowStatus to 'notInService'.rw Enumeration .1.3.6.1.4.1.9.10.72.1.2.1.2 |
cApsConfigMinSearchUpIntervalThis object is instantiated only when the standby interface
is not monitored. If both interfaces go down and the standby
interface is not monitored, successive switchovers may be used
in order to search for an interface that is up.
This object specifies the minimum time interval between
switchovers when both interfaces go down. A backoff algorithm
should be used to increase the time interval between
successive switchovers.rw Integer32 .1.3.6.1.4.1.9.10.72.1.2.1.3 |
cApsConfigMaxSearchUpIntervalThis object is instantiated only when the standby interface
is not monitored. If both interfaces go down and the standby
interface is not monitored, successive switchovers may be used
in order to search for an interface that is up.
This object specifies the maximum time interval between
switchovers when both interfaces go down.rw Integer32 .1.3.6.1.4.1.9.10.72.1.2.1.4 |
cApsConfigSwitchoverEnableIntervalThis object specifies the value of the timer to control
the minimum interval between switchovers. After a switchover,
APS is re-enabled only after this amount of time has elapsed,
in order to prevent quick successive switchovers.rw Integer32 .1.3.6.1.4.1.9.10.72.1.2.1.5 |
cApsConfigMessageTransportThis object specifies the type of transport configured for
exchange of APS protocol messages. The type of transport
currently being used is indicated in the
cApsStatusMessageTransport object.
When this object is set to 'ip', values must be specified
for the cApsConfigFarEndIpAddressType, cApsConfigFarEndIpAddress
and cApsConfigFarEndGroupName objects.rw CApsMessageTransport .1.3.6.1.4.1.9.10.72.1.2.1.6 |
cApsConfigMessageHolddownThe value specified in this object applies when the value of
cApsStatusMessageTransport is 'dcc', 'ip', or 'osc'.
APS messages are exchanged between systems to support
bidirectional or linear operation. To avoid potential
system misbehavior in which APS messages would be
triggered in an uncontrolled fashion, a hold down timer
is introduced that prevents successive event-triggered
APS messages from being sent in too short a time
interval.
This object specifies the minimum time between
event driven requests.rw Integer32 .1.3.6.1.4.1.9.10.72.1.2.1.7 |
cApsConfigMessageHolddownCountThe value specified in this object applies when the value of
cApsStatusMessageTransport is 'dcc', 'ip', or 'osc'.
The maximum number of APS messages that can be sent within
one cApsConfigMessageHolddown interval.rw Integer32 .1.3.6.1.4.1.9.10.72.1.2.1.8 |
cApsConfigMessageMaxIntervalThe value specified in this object applies when the value of
cApsStatusMessageTransport is 'dcc', 'ip', or 'osc'.
An APS message is sent unconditionally, whenever the amount
of time specified by this object has elapsed since the last
transmission of an APS message.rw Integer32 .1.3.6.1.4.1.9.10.72.1.2.1.9 |
cApsConfigFarEndGroupNameThe value specified in this object applies when the value of
cApsStatusMessageTransport is 'dcc', 'ip', or 'osc'.
APS messages, used to support bidirectional or linear
operation, can be sent out-of-band over an IP network.
In this case, this object is used to specify the a textual
name for the APS group at the far-end to which the message
is being sent.rw SnmpAdminString .1.3.6.1.4.1.9.10.72.1.2.1.10 |
cApsConfigFarEndIpAddressTypeThis object can be set only when the value of
cApsConfigMessageTransport is 'ip'.
