Category: IP Routing & Forwarding, Nortel Magellan Passport

Description: Defines SNMP objects for virtual router instances and IP forwarding on Nortel Magellan Passport multiservice 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 Nortel-Magellan-Passport-VirtualRouterMIB?

This is a Nortel Magellan Passport multiservice switch MIB defining objects for virtual router (VR) instances that partition IP forwarding within the platform. It exposes configuration and status data for each virtual router, including its component name, storage type, index, SNMP administrative status, and management access controls. Operationally, Nortel-Magellan-Passport-VirtualRouterMIB SNMP monitoring is used to confirm whether each virtual router instance is active and reachable for SNMP management, which reflects the software-level health of the routing partition rather than physical hardware; a failed or missing vrRowStatus entry signals a router instance that is down or misconfigured. It is a proprietary Nortel Magellan Passport extension and depends on the platform's own enterprise MIB tree rather than a standard IETF module. It is deployed on legacy Nortel/Tasman Magellan Passport WAN switches used by carriers for multiservice packet switching.

IPNetwork Monitor allows you to monitor SNMP objects defined in Nortel-Magellan-Passport-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 Magellan Passport multiservice switch

Monitoring Examples

An operator would poll the vrRowStatusTable (indexed by vrIndex) to enumerate configured virtual routers and check vrRowStatus for each vrComponentName, confirming the row is active(1) rather than notInService or notReady. The vrAdminContorlTable's vrSnmpAdminStatus and vrManagementAccess objects would be checked to verify a given virtual router still accepts SNMP management, with vrVirtualPrivateIntranetIdentifier used to correlate the VR to a specific VPN/intranet instance. An unexpected change in vrStorageType or a row disappearing from the table would indicate a configuration was deleted or corrupted.

What Can Be Monitored

  • virtual router row status
  • virtual router SNMP admin status
  • management access mode
  • virtual private intranet identifier
  • virtual router storage type
