What Is Nortel-MsCarrier-MscPassport-UnackTrunksMIB?

This is a Nortel private MIB for the MainStreet/Passport carrier switching platform (MsCarrier/MscPassport), covering "unacknowledged" (best-effort) trunk provisioning and state on Passport switches. It exposes provisioning tables (mscTrkUnAckedProvTable) with parameters like maximum errored interval and receive error sensitivity, row-status/administrative tables for adding and deleting trunks, and a state table (mscTrkUnAckedStateTable) reflecting current operational condition. Its role is monitoring the software/configuration status of trunk components - tracking error thresholds, row status (active/notInService/etc.), and framer-level component naming to detect misconfigured or degraded unacknowledged trunks before they impact best-effort traffic. As part of the broader Nortel Passport MIB family it depends on shared Passport conventions like component naming and storage-type semantics used across other MscPassport MIBs. It is deployed in legacy Nortel Passport-based carrier and enterprise WAN switching networks that still carry best-effort trunk traffic. Engineers can download the Nortel-MsCarrier-MscPassport-UnackTrunksMIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in Nortel-MsCarrier-MscPassport-UnackTrunksMIB. 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/Bay Networks Passport (MsCarrier/MscPassport) carrier switches

Monitoring Examples

A carrier NOC would poll mscTrkUnAckedStateTable to check the operational state of trunks provisioned in mscTrkUnAckedProvTable, watching mscTrkUnAckedMaximumErroredInterval and mscTrkUnAckedReceiveErrorSensitivity for signs a trunk is exceeding its configured error tolerance. mscTrkUnAckedRowStatusTable's mscTrkUnAckedRowStatus reveals whether a trunk entry is active, in test, or has failed to come into service after provisioning. Tracking mscTrkUnAckedComponentName alongside mscTrkUnAckedFramer helps correlate a flagged trunk back to a specific physical framer card.

What Can Be Monitored

  • trunk row/provisioning status
  • maximum errored interval threshold
  • receive error sensitivity
  • trunk operational state
  • component/framer association
