What Is Nortel-MsCarrier-MscPassport-VirtualRouterMIB?

This MIB manages virtual router (VR) instances on Nortel's (later Alcatel-Lucent) MsCarrier Passport multiservice switching platform, a carrier-grade routing/switching product line. Categories exposed include VR provisioning/configuration (row creation and lifecycle state), SNMP management access control per VR, and VPN/intranet identifier binding for each virtual router. It emphasizes monitoring the software-defined status of each VR instance — whether it is active, being created, or being destroyed, and whether SNMP management is enabled for it — functioning as a health/provisioning check on the Passport's virtualized routing layer rather than physical sensors. It relies on standard SNMPv2-TC constructs such as RowStatus and StorageType to model VR lifecycle, alongside Passport's own chassis/routing MIBs for underlying context. It is deployed on carrier-grade Nortel/Alcatel-Lucent Passport 15000/20000-series nodes providing multi-tenant virtual routing and VPN services. Browsing the Nortel-MsCarrier-MscPassport-VirtualRouterMIB OID tree directly is often the quickest way for an operator to confirm exactly which mscVr objects a given Passport software release actually implements.

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

  • Nortel/Alcatel-Lucent MsCarrier Passport multiservice switch
  • carrier routing/VPN platform

Monitoring Examples

An admin would walk mscVrRowStatusTable indexed by mscVrIndex to see which virtual router instances exist and their mscVrRowStatus (active, notInService, createAndGo), revealing whether a customer's VR was successfully provisioned or is stuck mid-creation. Polling mscVrAdminContorlTable's mscVrSnmpAdminStatus and mscVrManagementAccess shows whether SNMP-based management is enabled for a given VR, useful for diagnosing why it isn't responding to management traffic. mscVrVirtualPrivateIntranetIdentifier ties a VR instance to its VPN/intranet identifier, letting an operator confirm the virtual router is bound to the correct customer VPN. A VR row stuck in a transitional mscVrRowStatus or an unexpected mscVrStorageType would indicate a provisioning failure on the Passport node.

What Can Be Monitored

  • virtual router provisioning/row status
  • SNMP management access per virtual router
  • VPN/intranet identifier binding
  • virtual router storage type
