What Is Nortel-Magellan-Passport-FrameRelayUniTraceMIB?

Nortel-Magellan-Passport-FrameRelayUniTraceMIB is a Nortel enterprise MIB for the Magellan Passport WAN switching platform that configures protocol trace/diagnostic capture on Frame Relay UNI (User-Network Interface) links. It exposes row-status-controlled trace configuration objects -- component name, storage type, trace index -- and operational trace objects such as receiver name, capture duration, and queue limit, letting an operator start, stop, and filter a live protocol trace on a Frame Relay interface. Its monitoring value is diagnostic/software in nature: it is used to capture and inspect Frame Relay UNI signaling behavior during troubleshooting sessions rather than to continuously report hardware sensor values, effectively giving visibility into protocol-level faults on the Frame Relay link. It is built specifically against Nortel's Magellan Passport component/row-status conventions and Frame Relay UNI signaling concepts rather than a general IETF Frame Relay MIB. It is deployed on legacy Nortel Magellan Passport WAN switches used in carrier Frame Relay networks, where the Nortel-Magellan-Passport-FrameRelayUniTraceMIB reference supports interface-level protocol diagnostics.

IPNetwork Monitor allows you to monitor SNMP objects defined in Nortel-Magellan-Passport-FrameRelayUniTraceMIB. 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.

Monitoring Examples

An engineer troubleshooting a flapping Frame Relay UNI link would create a trace entry via frUniTraceRowStatusTable, set frUniTraceComponentName to target the specific interface, and configure frUniTraceDuration and frUniTraceQueueLimit to bound the capture. Once active, the frUniTraceOperationalTable's frUniTraceReceiverName identifies where captured frames are being sent for analysis; a trace that immediately hits its frUniTraceQueueLimit would indicate an unexpectedly high rate of UNI signaling messages, pointing to link instability.
