Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is Nortel-MsCarrier-MscPassport-FrameRelayNniTraceMIB?

This proprietary Nortel MIB is part of the MscPassport family for the Nortel (Magellan) Passport/MscCarrier multiservice WAN switching platform, specifically covering diagnostic packet tracing on Frame Relay Network-to-Network Interface (NNI) links. It exposes configuration data for creating trace components, filters, and receivers rather than steady-state traffic counters. For device health monitoring it is used less for hardware status and more to verify software-level protocol behavior: administrators check whether a trace session is active, its operational state, duration, and queue limit, to detect stalled or misconfigured tracing components. It depends on the broader MscPassport component-object model (shared row-status, storage-type, and component-naming conventions used across the Passport MIB family) rather than any standard IETF MIB. Typical deployment is on carrier-grade Nortel Passport WAN switches, where operations staff capture and inspect live Frame Relay NNI signalling or data frames to troubleshoot interconnect problems between carrier networks. Engineers can download the Nortel-MsCarrier-MscPassport-FrameRelayNniTraceMIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in Nortel-MsCarrier-MscPassport-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

An engineer provisions an entry in mscFrNniTraceRowStatusTable via mscFrNniTraceRowStatus to create a trace instance identified by mscFrNniTraceIndex and mscFrNniTraceComponentName, then checks mscFrNniTraceOperationalTable to confirm the trace is running. Polling mscFrNniTraceDuration and mscFrNniTraceQueueLimit reveals whether the trace session has expired or its capture buffer is close to overflowing, while mscFrNniTraceReceiverName identifies which receiver component is collecting the captured frames. If the operational entry shows the trace inactive shortly after activation, that typically indicates a misconfigured filter (mscFrNniTraceFilter) or a full queue dropping the session.

What Can Be Monitored

trace row status
trace operational state
trace duration
