What Is TIMETRA-PORT-MIB?

TIMETRA-PORT-MIB is a Nokia (formerly Alcatel-Lucent) proprietary MIB used to manage and provision the physical port hardware, Ethernet parameters, and statistics of the Alcatel-Lucent/Nokia 7750 SR service router (SROS) product family. It exposes per-port hardware inventory and configuration data—port type, class, description, name/alias, and MAC addressing—along with a last-change timestamp table tracking configuration modifications. Its monitoring emphasis is squarely on physical port hardware status: tmnxPortType/tmnxPortClass identify the physical port hardware installed, tmnxPortMacAddress and tmnxPortUserAssignedMac track addressing, and tmnxPortLastChangeTime/tmnxPortTableLastChange flag when port configuration or state last changed, useful for detecting unexpected hardware or link reconfiguration events. It is part of the broader TIMETRA/ALCATEL-IND1 MIB family and depends on shared Timetra textual conventions (e.g., ALCATEL-IND1-TIMETRA-TC-MIB) for its data types. It is deployed by service providers running Nokia 7750 SR (and related SROS-based) routers in core and edge network roles. TIMETRA-PORT-MIB SNMP monitoring is commonly integrated into NMS platforms tracking Nokia 7750 SR port hardware alongside chassis and card MIBs to build a complete physical inventory view.

IPNetwork Monitor allows you to monitor SNMP objects defined in TIMETRA-PORT-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.

Supported Devices

  • Nokia/Alcatel-Lucent 7750 SR (SROS) service router platforms, entire product line (physical port hardware inventory/config status)

Monitoring Examples

An operator would poll tmnxPortTable/tmnxPortEntry indexed by tmnxPortPortID to inventory installed port hardware via tmnxPortType and tmnxPortClass, and check tmnxPortDescription/tmnxPortName/tmnxPortAlias for consistent naming across a chassis. Watching tmnxPortLastChangeTime and the table-level tmnxPortTableLastChange reveals when a port's configuration changed unexpectedly, which could indicate an unauthorized change or a card reseat. Comparing tmnxPortMacAddress against tmnxPortUserAssignedMac would confirm whether a port is using its factory-assigned or an operator-overridden MAC address.

What Can Be Monitored

  • port type and class
  • port name/alias/description
  • port MAC address (factory vs. user-assigned)
  • port configuration last-change time
  • port table change tracking

How to Use in IPNetwork Monitor

Example using tmnxDDMTemperature OID:

Select a Nokia/Alcatel-Lucent 7750 SR (SROS) service router 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 tmnxDDMTemperature 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. It reports the current temperature of the SFF transceiver, in 1/256th of a degree Celsius. 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 Integer32-type OID, Value bounds is the most useful condition here — trigger an alert if the reported value exceeds the level expected for healthy operation, since sustained high optical-module temperature often precedes transceiver degradation. Click Finish to create the monitor; you can adjust any parameter later.

FAQ

What does TIMETRA-PORT-MIB provide for tracking physical port hardware on a Nokia 7750 SR router?
It exposes per-port inventory and configuration data -- port type and class, description, name/alias, and MAC address (factory vs. user-assigned) -- letting operators build a complete physical port inventory for the 7750 SR (SROS) platform, typically alongside chassis and card MIBs.

How would TIMETRA-PORT-MIB help detect an unexpected port reconfiguration?
The tmnxPortLastChangeTime and tmnxPortTableLastChange objects record when a port's configuration or the port table last changed, so an operator can flag an unexpected hardware or link reconfiguration event on a 7750 SR by watching for a change timestamp that doesn't correspond to a planned maintenance window.
