Description: TIMETRA-LMP-MIB module

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is TIMETRA-LMP-MIB?

TIMETRA-LMP-MIB is a Nokia (formerly Alcatel-Lucent) proprietary SNMP module for the SR OS operating system, part of the TIMETRA enterprise MIB family used on 7750/7450/7250 routers. It exposes configuration and operational state for the Link Management Protocol (LMP), a GMPLS control-plane protocol that verifies control-channel connectivity and correlates data-link properties between neighboring optical/packet nodes on a per-virtual-router basis. Administrators use it to monitor administrative and operational state of LMP instances and peer relationships, effectively tracking whether the control-plane link-management session to a neighbor is up or down. Because LMP underpins GMPLS-based transport signaling, this MIB is typically polled alongside other TIMETRA GMPLS/MPLS MIBs (e.g. TE, RSVP) rather than in isolation. It is deployed on carrier-grade Nokia SROS routers/optical-transport edge nodes in GMPLS-enabled backbone or metro networks, and the TIMETRA-LMP-MIB download lets administrators load it directly into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in TIMETRA-LMP-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 7750 SR / 7450 ESS / 7250 IXR routers running SR OS
  • GMPLS-enabled optical/packet transport nodes

Monitoring Examples

An operator would poll tmnxLmpVRtrTable/tmnxLmpVRtrEntry to see per-virtual-router LMP administrative (tmnxLmpVRtrAdminState) and operational (tmnxLmpVRtrOperState) state, flagging a mismatch (admin up, oper down) as a control-channel failure to a peer. The tmnxLmpVRtrPeerTable lists discovered LMP peers, letting an admin confirm that a router's configured GMPLS loopback address (tmnxLmpVRtrGmplsLoopbackAddress) is correctly forming adjacencies. Polling tmnxLmpVRtrTableLastChanged/tmnxLmpVRtrLastChanged timestamps helps detect recent reconfiguration events that could correlate with a link-management outage.

What Can Be Monitored

  • LMP admin/operational state per virtual router
  • LMP peer adjacency table
  • GMPLS loopback address configuration
  • control-channel last-changed timestamps

How to Use in IPNetwork Monitor

Example using tmnxLmpVRtrCcInErrors OID:

Select a Nokia 7750 SR / 7450 ESS / 7250 IXR routers running SR OS (GMPLS Link Management Protocol peer 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 tmnxLmpVRtrCcInErrors 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 tmnxLmpVRtrCcInErrors indicates the number of inbound packets that contained errors preventing them from being processed by LMP. 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 a Counter32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases between polls, since a rising count of errors, failures, or discards often points to a real underlying problem. Click Finish to create the monitor; you can adjust any parameter later.
