Description: Manages MPLS label switching, LSP configuration, and forwarding entries on Bay Networks Rapid-City series switches.

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 RC-IP-MPLS-MIB?

RC-IP-MPLS-MIB is a Bay Networks/Nortel Accelar enterprise MIB managing MPLS label-switching configuration, covering global MPLS process settings alongside RSVP and LDP signaling protocol groups. It exposes objects such as global administrative status, router ID, TTL propagation and label/session/LSP/traffic-control management flags, and counters/settings for inactive LSP restart behavior. It is primarily a software/control-plane status MIB: administrators use it to confirm the MPLS process is enabled and healthy, and to track how often LSPs become inactive and are restarted, which signals underlying network instability. It builds on the general IETF MPLS architecture concepts (LSPs, RSVP-TE, LDP) while remaining a vendor-specific implementation. It is deployed on Bay Networks/Nortel Accelar switches used as MPLS provider-edge or core routers. Engineers can download the RC-IP-MPLS-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in RC-IP-MPLS-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

  • Bay Networks/Nortel Accelar (Rapid-City) routing switch

Monitoring Examples

An operator checks rcIpMplsGlobalAdminStatus and rcIpMplsGlobalRouterId to confirm MPLS is enabled with the correct router identity, then watches rcIpMplsGlobalInactiveLspRestartCount together with rcIpMplsGlobalInactiveLspRestartTime to see how frequently LSPs are dropping and restarting, a high count suggests link flaps or signaling instability. rcIpMplsRsvpGroup and rcIpMplsLdpGroup objects let the admin verify RSVP-TE and LDP signaling settings (e.g., rcIpMplsGlobalLspMerge, rcIpMplsGlobalDiffServDef) are configured consistently across the MPLS domain.

What Can Be Monitored

  • MPLS global admin status
  • router ID
  • inactive LSP restart count/time
  • LSP merge/DiffServ settings
  • RSVP/LDP signaling configuration
