What Is Nortel-MsCarrier-MscPassport-VnsMIB?

Nortel-MsCarrier-MscPassport-VnsMIB is a Nortel (MsCarrier) enterprise MIB for the Passport WAN switching platform, managing Virtual Networking Service (VNS) connections and routing. It exposes VNS provisioning tables covering logical network numbers, link-to-protocol port mappings, and maximum transmission unit settings, alongside row-status/storage-type tracking for each VNS component. It is used mainly for configuration and software-state monitoring, confirming via row status that a VNS instance is correctly provisioned and active, and checking MTU settings to diagnose fragmentation-related performance issues on a WAN link, rather than for hardware sensor data. It is part of Nortel's broader MsCarrier Passport MIB family and depends on shared Passport component-naming conventions used across related modules. It is typically deployed on legacy Nortel/MsCarrier Passport WAN switches providing virtual networking services in carrier or large-enterprise wide-area networks. Engineers can download the Nortel-MsCarrier-MscPassport-VnsMIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in Nortel-MsCarrier-MscPassport-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/MsCarrier Passport WAN switch

Monitoring Examples

mscRtgVnsProvTable/Entry provisions VNS instances with mscRtgVnsLogicalNetworkNumber, mscRtgVnsLinkToProtocolPort, and mscRtgVnsMaximumTransmissionUnit, while mscRtgVnsRowStatusTable/Entry tracks mscRtgVnsRowStatus and mscRtgVnsStorageType for each VNS component. An admin checks mscRtgVnsRowStatus to confirm a virtual network service is active, and reviews the configured MTU to diagnose fragmentation issues on a Passport WAN link.

What Can Be Monitored

  • VNS provisioning row status
  • logical network number
  • link-to-protocol port mapping
  • configured MTU
