Description: Alcatel 7750 SR service router LDP MIB for managing MPLS Label Distribution Protocol sessions and label bindings.

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 ALCATEL-IND1-TIMETRA-LDP-MIB?

ALCATEL-IND1-TIMETRA-LDP-MIB is an Alcatel-Lucent (Timetra/SROS) enterprise MIB for the 7x50 SR router family, covering the Label Distribution Protocol (LDP) used to establish MPLS label-switched paths. It exposes a general LDP table per virtual router describing administrative and operational state, the LDP LSR identifier, protocol version, FEC deaggregation setting, and keepalive/hello timer factors and timeouts. This MIB is used to monitor the software/protocol-layer status of MPLS label distribution -- specifically whether LDP is administratively and operationally up on a given virtual router, and whether keepalive/hello timers are configured consistently with neighbors -- functioning as an MPLS control-plane health MIB rather than hardware sensor telemetry. As part of the TIMETRA/SROS family it depends on and complements standard MPLS/LDP-related IETF MIBs (e.g. MPLS-LDP-STD-MIB) for broader label-switching context. It is deployed in service-provider backbone networks running Alcatel-Lucent 7x50 SR routers as part of an MPLS core. Network engineers evaluating or troubleshooting this functionality can download the ALCATEL-IND1-TIMETRA-LDP-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in ALCATEL-IND1-TIMETRA-LDP-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

  • Alcatel-Lucent 7x50 SR series routers

Monitoring Examples

An administrator would poll vRtrLdpGeneralTable (via vRtrLdpGeneralEntry rows) to check vRtrLdpGenAdminState against vRtrLdpGenOperState, revealing whether LDP is enabled but failing to reach an operational state on a given virtual router. Checking vRtrLdpGenKeepAliveTimeout and vRtrLdpGenHelloTimeout against neighboring routers helps diagnose LDP session flapping caused by timer mismatches, while vRtrLdpGenLdpLsrId confirms the LSR identity used in label distribution.

What Can Be Monitored

  • LDP administrative and operational state
  • LDP LSR identifier
  • protocol version
  • keepalive timer factor and timeout
  • hello timer factor and timeout
  • FEC deaggregation setting

How to Use in IPNetwork Monitor

Example using vRtrLdpStatsOperDownEvents OID:

Select a Nokia (Alcatel-Lucent) 7750 SR-series 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 vRtrLdpStatsOperDownEvents 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 vRtrLdpStatsOperDownEvents specifies the number of times the LDP instance has gone operationally down since the instance was created. 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.
