What Is Nortel-MsCarrier-MscPassport-BaseRoutingMIB?

This MIB is part of Nortel's MsCarrier MscPassport family, a carrier-grade multiservice switching/routing platform used in ATM/Frame Relay/IP carrier networks. It belongs to the carrier routing/multiprotocol switching technology area. Its data centers on routing configuration objects — provisioning tables for routing components, row-status-controlled creation/deletion of routing entries, storage type, and traffic-splitting region assignments — reflecting configuration/provisioning rather than raw performance counters. It supports monitoring of software/configuration status by exposing row status (active/notInService/notReady) for routing components and tandem traffic settings, letting an operator detect misconfigured or inactive routing instances. Opening this module in a Nortel-MsCarrier-MscPassport-BaseRoutingMIB MIB Browser makes the shared mscRtg naming convention across the routing-table family easy to trace. It is one of many Nortel MsCarrier MIB modules sharing the mscRtg/baseRoutingMIB naming convention and depends on Nortel's broader MscPassport MIB tree and the RowStatus textual convention from SNMPv2-TC. It is deployed in legacy carrier/service-provider networks still running Nortel Passport ATM/multiservice switching platforms.

IPNetwork Monitor allows you to monitor SNMP objects defined in Nortel-MsCarrier-MscPassport-BaseRoutingMIB. 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.

Monitoring Examples

An operator would poll mscRtgProvTable/mscRtgProvEntry to check routing component provisioning and mscRtgRowStatusTable/mscRtgRowStatusEntry's mscRtgRowStatus column, keyed by mscRtgIndex, to confirm each routing entry is active rather than stuck in notInService or notReady. The mscRtgTandemTraffic object would be checked to verify tandem traffic handling is configured as expected on a routing component. mscRtgSplittingRegionIdsTable/mscRtgSplittingRegionIdsEntry would be inspected to confirm traffic-splitting region assignments match the intended routing design, revealing misrouted traffic if a region ID is wrong.

What Can Be Monitored

  • routing component row status
  • routing provisioning entries
  • tandem traffic configuration
  • traffic-splitting region assignment
  • routing component storage type
