UPF SessMgr Functionality

Following are the modifications done in the UPF session manager to support this feature:

  • Provide services to the CLI for enabling or disabling the MonSub tracing.

  • Control NPUMgr to connect/start/stop/add/delete MonSub sessions.

  • Based on the instructions from the CLI, configures panopticon (through NPUMgr) for changes, such as packet size and priority.

  • Read the "hex dump module" configurations to manage the storage of generated pcap files.

  • If the file copy fails or there are problems with session manager MonSub instantiation, raises the SNMP alarms.

  • Capture the control or slowpath packets as a separate slowpath PCAP.

  • This feature supports a maximum of four monitor subscriber tracing sessions for a UPF instance. The NPUMgr enforces the tracing limit.

  • The MonSub tracing session terminates in the absence of no space on hard disk or no hard disk.
