What Is Nortel-Magellan-Passport-UnackTrunksMIB?

This is a Nortel Magellan Passport WAN switching platform enterprise MIB that manages 'unacknowledged' (connectionless/UNACK) trunk services used for datagram-style transport between Passport switches. It exposes row-status and provisioning tables for these trunks, including component naming, storage type, framer association, maximum errored interval, and receive-error sensitivity, which together define the trunk's fault-tolerance configuration. Its monitoring value centers on the operational/configuration status of the trunk's connectionless service and its error-handling behavior - whether a trunk is provisioned, how sensitive it is to receive errors, and its error interval thresholds - rather than raw hardware sensors. As a Passport-family MIB it is closely tied to Nortel's proprietary Magellan Passport component/entity naming and row-status conventions used across its other trunk and framer MIBs. It is typically deployed on legacy Nortel Magellan Passport wide-area packet switches in carrier networks running connectionless trunk services. Engineers can download the Nortel-Magellan-Passport-UnackTrunksMIB file directly to load it into their MIB browser.

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

Monitoring Examples

An operator would check trkUnAckedRowStatusTable/Entry via trkUnAckedRowStatus and trkUnAckedComponentName to confirm a given unacknowledged trunk is active and correctly named, then consult trkUnAckedProvTable's trkUnAckedMaximumErroredInterval and trkUnAckedReceiveErrorSensitivity to verify its error-tolerance provisioning. If trkUnAckedRowStatus shows a trunk stuck in a not-ready or not-in-service state while trkUnAckedFramer indicates the underlying framer is up, that discrepancy points to a trunk provisioning problem rather than a physical-layer fault.

What Can Be Monitored

  • trunk row status
  • trunk component name
  • maximum errored interval
  • receive error sensitivity
  • framer association
  • trunk storage type
