Opened: Jun 08, 2016
Severity: 4-Minor


On ePVA platforms, if fastL4 profile is configured with immediate idle timeout and the flow was offloaded at embryonic, the server still acts as the flow has not timeout, and continues to send packets to client.


Some flows that should have timed-out and should no longer exist is still alive.


Users have flows that passes through virtual IP with a "idle-timeout immediate" setting may not have the expected behaviors.


Set "pva-acceleration" to "none" for the FastL4 profile.

Fix Information

Now all flows goes through the virtual IP configured with a fastL4 profile and has idle-timeout to immediate will timeout immediate as expected.

Behavior Change
