Description: Defines SNMP objects for Virtual Networking Services configuration and statistics on Nortel Magellan Passport 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-VnsMIB?

This is a proprietary Nortel Magellan Passport MIB for Virtual Networking Services (VNS), a legacy Nortel Passport WAN switch feature providing logical/virtual network overlays. It exposes row-status-based provisioning objects for VNS components (component name, storage type, index) plus a provisioning table capturing logical network number, link-to-protocol-port association, and maximum transmission unit for each virtual network service instance. Its monitoring value is chiefly in configuration/software provisioning status: RowStatus values indicate whether a VNS instance is active, not in service, or being provisioned, and MTU settings can be checked against expected link parameters to catch fragmentation-related faults. It relies on the vendor's proprietary Magellan-Passport enterprise SMI conventions rather than IETF-standard MIBs. It is typically deployed on legacy Nortel Magellan Passport carrier WAN switches used by telecom carriers for multiservice/virtual network overlay provisioning, now largely retired equipment. Engineers can download the Nortel-Magellan-Passport-VnsMIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in Nortel-Magellan-Passport-VnsMIB. 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 WAN switch (legacy)

Monitoring Examples

Checking rtgVnsRowStatusTable's rtgVnsRowStatus for a given rtgVnsIndex confirms whether a VNS instance is active or stuck in a notInService/createAndWait state, indicating an incomplete provisioning step. rtgVnsProvTable's rtgVnsLogicalNetworkNumber and rtgVnsMaximumTransmissionUnit let an operator verify the virtual network is bound to the correct logical network and that MTU matches the underlying link, since an MTU mismatch here would explain fragmentation or connectivity issues on that VNS instance.

What Can Be Monitored

  • VNS instance row status (active/notInService)
  • logical network number
  • link-to-protocol-port association
  • configured MTU per VNS instance
