Description: TIMETRA-GMPLS-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-GMPLS-MIB?

TIMETRA-GMPLS-MIB is a Nokia (formerly Alcatel-Lucent) enterprise MIB that manages and provisions Generalized MPLS (GMPLS) extensions on the SROS operating system used by 7750 SR and related routers. It falls into the MPLS/traffic-engineering configuration and status category, exposing per-virtual-router GMPLS general configuration and operational objects, including administrative/operational state, keepalive multiplier, LSP initialization retry timing, refresh timers, and rapid-retransmission parameters, plus a notification-prefix and conformance structure. Its monitoring value is on software/protocol status rather than physical hardware — confirming a virtual router's GMPLS instance is administratively and operationally up (vRtrGmplsGeneralAdminState/OperState), and that keepalive and LSP-retry timers are tuned appropriately to avoid unnecessary session flaps in optical/transport-integrated MPLS networks. It builds on Nokia's broader TIMETRA/SROS enterprise MIB tree and extends the standard MPLS/GMPLS signaling model (RFC 3945 and related GMPLS RFCs) into a vendor-specific management view. It is typically deployed on Nokia 7750 SR (and related SROS) routers in carrier networks that integrate packet and optical/transport GMPLS-controlled links. Engineers can download the TIMETRA-GMPLS-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in TIMETRA-GMPLS-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 router (SROS, GMPLS-enabled)

Monitoring Examples

An operator would poll vRtrGmplsGeneralTable/vRtrGmplsGeneralEntry to check vRtrGmplsGeneralAdminState against vRtrGmplsGeneralOperState for a virtual router's GMPLS instance, confirming it is both administratively enabled and operationally up. Reviewing vRtrGmplsGeneralKeepMultiplier, vRtrGmplsGenLspInitRetryTimeout, and vRtrGmplsGenRapidRetransmitTime/vRtrGmplsGenRapidRetryLimit would reveal whether GMPLS keepalive/retry timers are set too aggressively, a likely cause if the operator is seeing frequent unexpected GMPLS session or LSP re-establishment events (tmnxGmplsNotifyPrefix-rooted traps).

What Can Be Monitored

  • GMPLS admin/operational state per virtual router
  • keepalive multiplier/timer settings
  • LSP initialization retry timeout
  • rapid retransmit time/retry limit
  • GMPLS notification/trap activity

How to Use in IPNetwork Monitor

Example using vRtrGmplsPeerHelloTimeoutCount OID:

Select a Nokia (Alcatel-Lucent) 7750 SR router, SROS GMPLS-enabled (GMPLS instance admin/oper 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 vRtrGmplsPeerHelloTimeoutCount 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 vRtrGmplsPeerHelloTimeoutCount indicates number of times the Hello timeout timer expired for the peer. 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 sharply between polls relative to its normal baseline, since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.
