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.

show user-plane-service statistics charging action

This command displays charging action statistics for all or specified charging actions that are configured in the Active Charging Service (ACS). A charging action represents actions to be taken when a configured rule is matched. Actions range from generating accounting records to dropping the IP packet, and so on. The charging action also determines the metering principle—Whether to count retransmitted packets, and which protocol field to use for billing (L3/L4/L7, and so on).

Syntax

show user-plane-service statistics charging-action 
{ all [ debug-info | verbose] | name charging_action_name [ debug-info | verbose] }  [ | { grep grep_options | more } ] 

Notes:

  • all : Displays information for all charging actions configured in ACS.

  • name charging_action_name : Displays information for an existing charging action specified as an alphanumeric string from 1 through 63 characters.

This show CLI command doesn't support the following statistics with the value 0 that is displayed for each of its counter value.

show user-plane-service statistics group-of-ruledefs

This command displays statistics for all groups or a specified group of ruledef s configured in the active charging service. The group-of-ruledefs is a collection of rule definitions that can be used in access policy creation.

Syntax

show user-plane-service statistics group-of-ruledefs { all | name group_of_ruledefs_name } [ | { grep grep_options | more } ] 

Notes:

  • all : Displays information for all groups of ruledefs configured in ACS.

  • name group_of_ruledefs_name : Displays detailed information for an existing group of ruledefs specified as an alphanumeric string from 1 through 63 characters.

  • { grep grep_options | more } Pipes : Sends the output of this command to the specified command.

  • The following clear CLI command is available for use:
    clear user-plane-service statistics group-of-ruledefs { all | name group_of_ruledefs_name } 

show user-plane-service statistics ruledef

This command displays statistics for all or specified ruledef that is configured in an active charging service. The ruledef represents a set of matching conditions across multiple L3 - L7 protocol that is based on protocol fields and state information. You can use each ruledef across multiple rule bases within the active charging service.

Syntax

show user-plane-service statistics ruledef { all { charging | firewall [ wide ] | post-processing } | name ruledef_name [ wide ] } [ | { grep grep_options | more } ] 

Notes:

  • all : Displays statistics for all ruledef s of the specified type that is configured in the ACS.

  • charging : Displays statistics for all charging ruledef s configured in the ACS.

  • firewall : Displays statistics for all firewall ruledef s configured in the service.

  • post processing : Displays statistics for all post processing ruledef s configured in the ACS.

  • name ruledef_name : Displays statistics for an existing ruledef specified as an alphanumeric string from 1 through 63 characters.

  • wide : Displays all available information in a single wide line.

  • The following clear CLI command is available for use:
    clear user-plane-service statistics ruledef { all | charging | firewall | name group_of_ruledefs_name }
