What Is Nortel-MsCarrier-MscPassport-FrameRelayUniTraceMIB?

Nortel-MsCarrier-MscPassport-FrameRelayUniTraceMIB defines SNMP objects for packet tracing (diagnostic capture) on Frame Relay UNI (User-Network Interface) interfaces of Nortel MsCarrier MscPassport switches, used to troubleshoot Frame Relay traffic problems by capturing packets matching configured filters. It exposes row status/provisioning tables for trace sessions, an operational table with the receiver name, trace duration, and queue limit for captured packets, and a filter sub-component that defines which packets are captured. This gives an operator a way to monitor and control active diagnostic trace sessions on a Frame Relay port -- essentially a software-level diagnostic-tool status monitor rather than a steady-state performance counter, useful for confirming a trace is running, how long it will run, and whether its capture queue is filling up. It uses the Passport RowStatus/StorageType conventions shared across the MIB family and applies specifically to Frame Relay UNI interfaces. It is used on Nortel MsCarrier MscPassport switches for on-demand Frame Relay traffic troubleshooting in carrier networks. Engineers can download the Nortel-MsCarrier-MscPassport-FrameRelayUniTraceMIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in Nortel-MsCarrier-MscPassport-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 operator sets up a capture by provisioning mscFrUniTraceRowStatusTable and checks mscFrUniTraceOperationalTable's mscFrUniTraceReceiverName, mscFrUniTraceDuration, and mscFrUniTraceQueueLimit to confirm where captured packets are being sent, how long the trace will run, and how much buffer space remains before frames are dropped. The mscFrUniTraceFilter sub-component defines which Frame Relay frames are captured, letting the operator narrow a trace to a specific DLCI or traffic pattern while diagnosing a reported connectivity or performance problem. A queue nearing mscFrUniTraceQueueLimit signals the trace buffer is about to overflow and older captured frames may be lost.
