e tmnxInterChassisCommsDown alarm is generated when the
active CPM cannot reach the far-end chassis.
          
[EFFECT] The resources on the far-end chassis are not available. This
event for the far-end chassis means that the CPM, SFM, and XCM cards
in the far-end chassis will reboot and remain operationally down until
communications are re-established.
          
[RECOVERY] Ensure that all CPM interconnect ports in the system are
properly cabled together with working cables.

e tmnxInterChassisCommsUp notification is generated when the
control communications are re-established between the active CPM and
the far-end chassis.
          
[EFFECT] The resources on the far-end chassis are now available. This
event for the far-end chassis means that the CPM, SFM and XCM cards in
the far-end chassis will start the process of coming back into
service.

e tmnxCpmIcPortDown alarm is generated when the CPM
interconnect port is not operational. The reason may be a cable
connected incorrectly, a disconnected cable, a faulty cable, or a
misbehaving CPM interconnect port or card.
          
[EFFECT] At least one of the control plane paths used for
inter-chassis CPM communication is not operational. Other paths may be
available.
          
[RECOVERY] A manual verification and testing of each CPM interconnect
port is required to ensure fully functional operation. Physical
replacement of cabling may be required.

e tmnxCpmIcPortUp notification is generated when the CPM
interconnect port is operational again.
          
[EFFECT] A control plane communication path between CPM cards in the
different chassis have been established.

e tmnxCpmIcPortSFFInserted notification is generated when
the small form factor (SFF) pluggable optical module (e.g. QSFP) is
inserted into a CPM interconnect port.
          
[EFFECT] This event is for notification only.

e tmnxCpmIcPortSFFRemoved notification is generated when the
SFF (e.g. QSFP) is removed from the CPM interconnect port. Removing an
SFF causes both this trap, and also a tmnxCpmIcPortDown event.
          
[EFFECT] Removing the SFF will cause the CPM interconnect port to go
down. This port will no longer be able to be used as part of the
control plane between chassis but other paths may be available.
          
[RECOVERY] Insert a working SFF into the port.

e tmnxCpmNoLocalIcPort alarm is generated when the CPM
cannot reach the other chassis using its local CPM interconnect ports.
          
[EFFECT] Another control communications path may still be available
between the CPM and the other chassis via the mate CPM in the same
chassis. If that alternative path is not available then complete
disruption of control communications to the other chassis will occur
and the tmnxInterChassisCommsDown alarm is raised.
          
A tmnxCpmNoLocalIcPort alarm on the active CPM indicates that a
further failure of the local CPM interconnect ports on the standby CPM
will cause complete disruption of control communications to the other
chassis and the tmnxInterChassisCommsDown alarm is raised.
          
A tmnxCpmNoLocalIcPort alarm on the standby CPM indicates that a CPM
switchover may cause temporary disruption of control communications to
the other chassis while the rebooting CPM comes back into service.
          
[RECOVERY] Ensure that all CPM interconnect ports in the system are
properly cabled together with working cables.

e tmnxCpmLocalIcPortAvail notification is generated when the
CPM re-establishes communication with the other chassis using its
local CPM interconnect ports.
          
[EFFECT] A new control communications path is now available between
the CPM and the other chassis.

e tmnxCpmIcPortSFFStatusFailure notification is generated
when the value of tmnxCpmIcPortSFFStatus results in a value other than
'not-equipped (0)', or 'operational (1)'.
          
[EFFECT] The SFF device is not operational and the associated CPM
interconnect port can not be used. The SFF and port will not recover
without operator intervention.
          
[RECOVERY] Remove and re-insert the SFF device. If the problem
persists then replace the SFF device.

e tmnxCpmIcPortDDMFailure notification is generated when an
SFF in a CPM interconnect port that supports Digital Diagnostic
Monitoring (DDM) enters a failed state.

e tmnxCpmIcPortDDMFailure notification is generated when an
SFF in a CPM interconnect port that supports Digital Diagnostic
Monitoring (DDM) clears a failed state.

e tmnxSfmIcPortDown alarm is generated when the SFM
interconnect port is not operational. The reason may be a cable
connected incorrectly, a disconnected cable, a faulty cable, or a
misbehaving SFM interconnect port or SFM card.
          
[EFFECT] This port can no longer be used as part of the user plane
fabric between chassis. Other fabric paths may be available resulting
in no loss of capacity.
          
[RECOVERY] A manual verification and testing of each SFM interconnect
port is required to ensure fully functional operation. Physical
replacement of cabling may be required.

e tmnxSfmIcPortUp notification is generated when the SFM
interconnect port is operational again.
          
[EFFECT] This port can now be used as part of the user plane fabric
between chassis.

e tmnxSfmIcPortSFFInserted notification is generated when
the Small Form Factor (SFF) pluggable optical module (e.g. CXP) is
inserted into an SFM interconnect port.
          
[EFFECT] This event is for notification only.

e tmnxSfmIcPortSFFRemoved notification is generated when the
SFF (e.g. CXP) is removed from the SFM interconnect port.
          
[EFFECT] Removing the module will cause the port to go down. This
port can  no longer be used as part of the user plane fabric between
chassis. Other fabric paths may be available resulting in no loss of
capacity.
          
[RECOVERY] Insert a working SFF into the SFM interconnect port.

e tmnxSfmIcPortSFFStatusFailure notification is generated
when the value of tmnxSfmIcPortSFFStatus results in a value other than
'not-equipped (0)', or 'operational (1)'.
          
[EFFECT] The SFF device is not operational and the associated SFM
interconnect port can not be used. The SFF and port will not recover
without operator intervention.
          
[RECOVERY] Remove and re-insert the SFF device. If the problem
persists then replace the SFF device.

e tmnxSfmIcPortDDMFailure notification is generated when an
SFF in an SFM interconnect port that supports Digital Diagnostic
Monitoring (DDM) enters a failed state.

e tmnxSfmIcPortDDMFailure notification is generated when an
SFF in an SFM interconnect port that supports Digital Diagnostic
Monitoring (DDM) clears a failed state.

e tmnxSfmIcPortDegraded notification is generated when the
system has detected a degradation of the switch fabric that is
associated with a particular SFM interconnect port. The value of
tmnxSfmIcPortDegradeState will reflect this condition by having a
value that is NOT 'none (1)'. If the value of
tmnxSfmIcPortDegradeState is 'degraded (2)' the SFM interconnect port
can still carry some traffic but not at the full capacity of the port.
The port and attached cable are not necessarily the cause of the
degradation but are a likely cause.
          
[EFFECT] Switch fabric capacity on this port is reduced when
tmnxSfmIcPortDegradeState is degraded. This may not be causing any
impact to service because of redundancy in the fabric.
          
[RECOVERY] Although it may not be necessary to maintain full service,
replacing the affected components may restore some fabric capacity.

e tmnxSfmIcPortDegradedClear notification is generated when
the switch fabric associated with the SFM interconnect port is not
degraded. This occurs when the value of tmnxSfmIcPortDegradeState is
'none (1)'.
