What Is TIMETRA-CHASSIS-INTERCONNECT-MIB?

This MIB is a Nokia (formerly Alcatel-Lucent) proprietary module for the 7750 SR / SROS family of service routers, covering the interconnect fabric that links separate chassis together in a multi-chassis configuration. It exposes configuration and status data for the interconnect ports on both the Control Processor Module (CPM) and Switch Fabric Module (SFM), including port numbering and SFF (small form-factor pluggable) transceiver presence. It is explicitly useful for monitoring the hardware health of the interconnect links, most notably the operational state of each interconnect port and whether the SFF module is equipped and functioning, which flags failed or missing transceivers before they cause a fabric outage. As a Nokia SROS-specific extension it depends on the broader chassis and textual-convention MIB framework used across the Timetra suite. It's typically deployed in high-capacity multi-chassis 7750 SR / 7950 XRS core router installations where redundant fabric interconnects must be continuously monitored for availability, and engineers can get the TIMETRA-CHASSIS-INTERCONNECT-MIB download to load directly into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in TIMETRA-CHASSIS-INTERCONNECT-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Monitoring Examples

An operator would poll tmnxCpmIcPortTable and tmnxSfmIcPortTable, indexed by tmnxCpmIcPortNum / tmnxSfmIcPortNum, to check tmnxCpmIcPortOperState and tmnxSfmIcPortOperState for each interconnect port. Correlating tmnxCpmIcPortSFFEquipped with tmnxCpmIcPortSFFStatus reveals whether a given port has a transceiver installed and whether it is reporting a fault, letting an admin catch a degraded or unseated SFF before the interconnect link between chassis drops. tmnxChassisInterconNotifyPrefix roots the traps issued when an interconnect port's state changes.

What Can Be Monitored

interconnect port operational state
SFF transceiver presence
SFF transceiver status
CPM interconnect port number
SFM interconnect port number

How to Use in IPNetwork Monitor

Example using tmnxSfmIcPortDegradeState OID:

Select a Nokia/Alcatel-Lucent 7750 SR/7950 XRS multi-chassis router (interconnect port/SFF transceiver status) as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type tmnxSfmIcPortDegradeState into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. The value of tmnxSfmIcPortDegradeState indicates degradation of the switch fabric that is carried over a particular SFM interconnect port. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is an INTEGER-type OID, Value bounds is the most useful condition here — trigger an alert if the value is anything other than 'none', since that indicates the condition this object reports has changed to one worth investigating. Click Finish to create the monitor; you can adjust any parameter later.

tmnxInterChassisNotifications	1.3.6.1.4.1.6527.3.1.3.94.0.1
NTF tmnxInterChassisCommsDown	1.3.6.1.4.1.6527.3.1.3.94.0.1.1			[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.
NTF tmnxInterChassisCommsUp	1.3.6.1.4.1.6527.3.1.3.94.0.1.2			[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.
tmnxCpmIcPortNotifications	1.3.6.1.4.1.6527.3.1.3.94.0.2
NTF tmnxCpmIcPortDown	1.3.6.1.4.1.6527.3.1.3.94.0.2.1			[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.
NTF tmnxCpmIcPortUp	1.3.6.1.4.1.6527.3.1.3.94.0.2.2			[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.
NTF tmnxCpmIcPortSFFInserted	1.3.6.1.4.1.6527.3.1.3.94.0.2.3			[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.
NTF tmnxCpmIcPortSFFRemoved	1.3.6.1.4.1.6527.3.1.3.94.0.2.4			[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.
NTF tmnxCpmNoLocalIcPort	1.3.6.1.4.1.6527.3.1.3.94.0.2.5			[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.
NTF tmnxCpmLocalIcPortAvail	1.3.6.1.4.1.6527.3.1.3.94.0.2.6			[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.
NTF tmnxCpmIcPortSFFStatusFailure	1.3.6.1.4.1.6527.3.1.3.94.0.2.7			[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.
NTF tmnxCpmIcPortDDMFailure	1.3.6.1.4.1.6527.3.1.3.94.0.2.8			[CAUSE] The tmnxCpmIcPortDDMFailure notification is generated when an SFF in a CPM interconnect port that supports Digital Diagnostic Monitoring (DDM) enters a failed state.
NTF tmnxCpmIcPortDDMClear	1.3.6.1.4.1.6527.3.1.3.94.0.2.9			[CAUSE] The tmnxCpmIcPortDDMFailure notification is generated when an SFF in a CPM interconnect port that supports Digital Diagnostic Monitoring (DDM) clears a failed state.
tmnxSfmIcPortNotifications	1.3.6.1.4.1.6527.3.1.3.94.0.3
NTF tmnxSfmIcPortDown	1.3.6.1.4.1.6527.3.1.3.94.0.3.1			[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.
NTF tmnxSfmIcPortUp	1.3.6.1.4.1.6527.3.1.3.94.0.3.2			[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.
NTF tmnxSfmIcPortSFFInserted	1.3.6.1.4.1.6527.3.1.3.94.0.3.3			[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.
NTF tmnxSfmIcPortSFFRemoved	1.3.6.1.4.1.6527.3.1.3.94.0.3.4			[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.
NTF tmnxSfmIcPortSFFStatusFailure	1.3.6.1.4.1.6527.3.1.3.94.0.3.5			[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.
NTF tmnxSfmIcPortDDMFailure	1.3.6.1.4.1.6527.3.1.3.94.0.3.6			[CAUSE] The tmnxSfmIcPortDDMFailure notification is generated when an SFF in an SFM interconnect port that supports Digital Diagnostic Monitoring (DDM) enters a failed state.
NTF tmnxSfmIcPortDDMClear	1.3.6.1.4.1.6527.3.1.3.94.0.3.7			[CAUSE] The tmnxSfmIcPortDDMFailure notification is generated when an SFF in an SFM interconnect port that supports Digital Diagnostic Monitoring (DDM) clears a failed state.
NTF tmnxSfmIcPortDegraded	1.3.6.1.4.1.6527.3.1.3.94.0.3.8			[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.
NTF tmnxSfmIcPortDegradedClear	1.3.6.1.4.1.6527.3.1.3.94.0.3.9			[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)'.
