Monitoring and Troubleshooting User Plane in CUPS

This section provides information about the CLI commands available to monitor and/or troubleshoot User Plane in CUPS.

SNMP Traps

The following traps are available after session recovery in the User Plane node:

  • starManagerFailure: This trap is generated when there is failure in the Software manager.

  • starTaskFailed: This trap is generated when a noncritical task has failed and the appropriate recovery steps begin.

  • starTaskRestart: This trap is generated when a noncritical task has restarted after an earlier failure.

  • starSessMgrRecoveryComplete: This trap is generated when Session Manager recovery completes. This is typically caused by the failure of Session Manager task and successful completion of recovery.

  • starManagerRestart: This trap is generated when the identified manager task has been restarted.

Note
In CUPS, the "Packets Discarded" statistics are the aggregate of packets dropped at the Session manager and packets dropped at VPP. As VPP handles majority packets, the packet drops at VPP can only be categorized broadly under these statistics.

You can view specific packet drop reasons only for packets dropped at session manager. Packets dropped at VPP are categorized under Packets Discarded counter in the show gtpu statistics CLI.
