Operational commands and debugging

This section describes commands that can be used for operational and debugging purposes.

To display the number of PFCP associations and sessions, use the show subscriber-mgmt pfcp summary command.

To display PFCP message statistics, including information about packets that are received and transmitted and any transmission errors, use the show subscriber-mgmt pfcp statistics command.

To reset the PFCP association statistics to zero, use the clear subscriber-mgmt pfcp-association statistics command.

To display information including association-level parameters such as function features and node IDs, use the show subscriber-mgmt pfcp association command.

To display path state information, use the show subscriber-mgmt pfcp peer command.

See PFCP heartbeats and headless mode for information about the distinction between PFCP association and path.

To display default IBCP tunnel information, use the show subscriber-mgmt pfcp session default-tunnel command.

To display details about a specific PFCP session, use the show subscriber-mgmt pfcp session detail command. This command provides an overview for the PFCP parameters of the session. Various filters can be applied to narrow a specific session or set of sessions.

See Operational commands for more information about basic operational commands.

To forcefully remove a PFCP session, use the clear subscriber-mgmt pfcp-session command.

Caution: Although it is possible to forcefully remove a PFCP session, Nokia does not recommend invoking this command in a live network because this may cause the BNG CPF to be out of sync with the UPF. If the UPF contains a session that is not on the CPF, it is preferable to first run a manual PFCP audit.

To perform basic PFCP debugging, use the debug subscriber-mgmt pfcp command. The output of this command allows inspection of PFCP packets received and transmitted. As well, any session-specific failure is reported in the PFCP response to the BNG CPF, which can display the specific error as part of session debugging.
