Release

The show active-charging flows full all and show active-charging flows summary commands are enhanced to get the statistics from VPP. 21.26

The P-GW is enhanced to collect the log messages to monitor offloading and onloading flow transactions between VPP and the session manager.

21.26

The following enhancements were introduced:

  • Analyzer level statistics (TCP, UDP, P2P, HTTP, HTTPS)

  • VPP statistics collection using the CLI configuration

21.25

First introduced.

21.24

Feature Description

The show active-charging flows full command is enhanced to receive the per flow information from VPP. This command displays the VPP stream to flow mapping information.

The show active-charging flows full and show active-charging flows summary commands support the following filters:

  • imsi

  • ip-address

  • msisdn

  • username

  • callerid

  • flow-id

  • session-id

  • instance

For more information, see the VPP Metric Enhancement chapter in the P-GW Administration Guide.
