Release

The show active-charging flows full debug-info all command is enhanced to display timestamp accuracy between VPP and session manager. For more information, see the VPP Metric Enhancement chapter in the P-GW Administration Guide.

Feature Description

When data packets get offloaded, the calculated ticks from the last arrived packet time lag behind the Starent Network Transmission (SNX) global tick time in the session manager. This results in non-synchronization of time between VPP and session manager. As the flow timeout is deducted incorrectly, the flow gets removed from the session.

The show active-charging flows full debug-info all command is enhanced to display the correct flow idle timeout.
