What Is Nortel-Magellan-Passport-FrameRelayNniTraceMIB?

This Nortel Magellan Passport module provides diagnostic trace-capture configuration for Frame Relay NNI (Network-to-Network Interface) protocol exchanges on Passport switches, allowing operators to capture and analyze Frame Relay signaling/protocol traffic for troubleshooting. It exposes a row-status/provisioning table (frNniTraceRowStatusTable) for defining trace instances, and an operational table (frNniTraceOperationalTable) with parameters like trace receiver name, capture duration, and queue limit, along with a trace filter capability (frNniTraceFilter). Its monitoring role is diagnostic rather than continuous health telemetry: administrators activate and monitor a trace session's operational status and parameters (duration, queue limit, receiver) to capture Frame Relay NNI protocol behavior when troubleshooting signaling problems, such as verifying trace data isn't lost because a queue limit was exceeded. It builds on Frame Relay NNI signaling conventions (per Frame Relay Forum/ANSI standards) and shares the common Passport row-status/component pattern with sibling Passport modules. It was deployed on Nortel Magellan Passport Frame Relay switches for protocol-level diagnostics in carrier Frame Relay networks. Network engineers evaluating or troubleshooting this functionality can download the Nortel-Magellan-Passport-FrameRelayNniTraceMIB file directly to load it into their MIB browser.

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

A network engineer diagnosing an NNI signaling issue would configure a trace instance via frNniTraceRowStatusTable, then set frNniTraceDuration and frNniTraceQueueLimit in frNniTraceOperationalTable to bound the capture, directing captured frames to the destination named in frNniTraceReceiverName. If frNniTraceQueueLimit is reached during capture, some trace data would be dropped, which the engineer must account for when interpreting the results alongside any frNniTraceFilter criteria applied.
