The value of tmnxCpmIcPortTable represents CPM interconnect port information. A Control Plane Module (CPM) interconnect port (CPM IcPort) is a port on a CPM which provides the capability for two (or more) chassis to be connected and communicate with each other.

Each tmnxCpmIcPortEntry consists of the specific information pertaining to a CPM interconnect port for a particular card on a given chassis.

The value of tmnxCpmIcPortNum specifies a CPM interconnect port within a particular card on a given chassis.

The value of tmnxCpmIcPortOperState indicates the operational state for a given CPM interconnect port.

The value of tmnxCpmIcPortSFFEquipped indicates whether or not a small form factor (SFF) pluggable optical module (e.g. QSFP) is inserted into the CPM interconnect port.

The value of tmnxCpmIcPortSFFStatus indicates the operational status of the inserted SFF. If tmnxCpmIcPortSFFEquipped is false, the tmnxCpmIcPortSFFStatus will be 'not-equipped (0)', otherwise 'operational (1)' if no failure is detected.

The value of tmnxSfmIcPortTable represents SFM interconnect port information. A Switch Fabric Module (SFM) interconnect port (SFM IcPort) is a port on an SFM which provides the capability for two (or more) chassis to be connected and communicate with each other.

Each tmnxSfmIcPortEntry consists of the specific information pertaining to an SFM interconnect port for a particular card on a given chassis.

The value of tmnxSfmIcPortNum specifies an SFM interconnect port within a particular card on a given chassis.

The value of tmnxSfmIcPortOperState indicates the operational state for a given SFM interconnect port.

The value of tmnxSfmIcPortSFFEquipped indicates whether or not a small form factor (SFF) pluggable optical module (e.g. CXP) is inserted into the SFM interconnect port.

The value of tmnxSfmIcPortSFFStatus indicates the operational status of the inserted SFF. If tmnxSfmIcPortSFFEquipped is false, the tmnxSfmIcPortSFFStatus will be 'not-equipped (0)', otherwise 'operational (1)' if no failure is detected.

The value of tmnxSfmIcPortDegradeState indicates degradation of the switch fabric that is carried over a particular SFM interconnect port. The possible values are: none (1) - The port is not considered as degraded. degraded (2) - There is a degradation of the switch fabric that is carried over the port. The port can still carry some traffic but not at the full capacity of the port. Enumeration: 'none': 1, 'degraded': 2.

The value of tmnxSfmIcPortMisconSfm indicates the SFM that contains the SFM IcPort that is incorrectly connected to this SFM IcPort. If the value of tmnxSfmIcPortOperState is not 'invalid-connection (2)', the value of tmnxSfmIcPortMisconSfm is '0'.

The value of tmnxSfmIcPortMisconSfmIcPort indicates the SFM IcPort that this SFM IcPort is incorrectly connected to. If the value of tmnxSfmIcPortOperState is not 'invalid-connection (2)', the value of tmnxSfmIcPortMisconSfmIcPort is '0'.

The unique value of tmnxNotifyIcPortNum identifies the interconnect port number within a chassis in the system.

[CAUSE] The 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.

[CAUSE] The 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.

[CAUSE] The 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.

[CAUSE] The 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.

[CAUSE] The 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.

[CAUSE] The 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.

[CAUSE] The 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.

[CAUSE] The 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.

[CAUSE] The 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.

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

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

[CAUSE] The 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.

[CAUSE] The 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.

[CAUSE] The 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.

[CAUSE] The 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.

[CAUSE] The 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.

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

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

[CAUSE] The 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.

[CAUSE] The 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)'.
