Description: Manages Nokia carrier Ethernet MPLS-TP tunnel configuration and OAM state.

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 TN-MPLS-TP-MIB?

TN-MPLS-TP-MIB is a Nokia-proprietary SNMP MIB module for the Nokia SROS platform, used to provision and manage MPLS Transport Profile (MPLS-TP) tunnels and their OAM functions. It exposes configuration and status data for MPLS-TP tunnel identifiers, global/node identifiers, tunnel ID ranges, administrative state, and OAM template configuration used for continuity-check and fault-detection sessions on TP tunnels. Rather than hardware sensors, its monitoring value lies in tunnel/service health — administrative state reveals whether a tunnel is enabled, and configuration change timestamps reveal when tunnel provisioning last changed, both used to catch misconfigured or down transport-layer paths. It is a Nokia-proprietary router MIB built on Nokia's virtual-router ("vRtr") object-naming convention shared across other SROS MIBs, so it depends on that shared numbering/indexing scheme rather than a standards-based IETF MPLS-TP MIB. It is deployed on Nokia SROS-based carrier Ethernet/MPLS-TP routers in service-provider transport networks. Engineers can download the TN-MPLS-TP-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in TN-MPLS-TP-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 SROS-based router
  • carrier Ethernet/MPLS-TP transport router

Monitoring Examples

An admin polls vRtrMplsTpSystemTable/vRtrMplsTpSystemEntry to check vRtrMplsTpGlobalId and vRtrMplsTpNodeId configuration and confirm vRtrMplsTpAdminState shows the MPLS-TP subsystem enabled on a given virtual router. The vRtrMplsTpOamTemplateCfgTable (tracked via vRtrMplsTpOamTemplTblLastChanged) exposes OAM template configuration; a recent, unexpected change timestamp combined with a tunnel outside its configured vRtrMplsTpTunnelIdMin/vRtrMplsTpTunnelIdMax range would indicate a provisioning error.

What Can Be Monitored

  • MPLS-TP tunnel admin state
  • global/node ID configuration
  • tunnel ID range
  • OAM template configuration
  • configuration change timestamps

How to Use in IPNetwork Monitor

Example using vRtrMplsTpLspPtPathMepWTRTimer OID:

Select a Nokia SROS-based router, carrier Ethernet/MPLS-TP transport router (MPLS-TP tunnel/OAM admin 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 vRtrMplsTpLspPtPathMepWTRTimer 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 vRtrMplsTpLspPtPathMepWTRTimer indicates the remaining Wait-To-Restore time, in seconds, before the protection path can switch back to the working path. 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 value stays unexpectedly high or low relative to what you'd expect for this timer, since that can indicate a stuck or stale state. Click Finish to create the monitor; you can adjust any parameter later.
