Known Affected Versions:
12.1.0, 12.1.0 HF1, 12.1.0 HF2, 12.1.1, 12.1.1 HF1, 12.1.1 HF2

Opened: May 10, 2016
Severity: 3-Major


When a fastL4 profile's pva-offload-state set to establish (default is embryonic), the corresponding UDP virtual server using that profile won't offload UDP traffic and causes performance degradation.


Performance degradation.


This issue is introduced during v12.0.0 development and only impacts v12.1.0 and v12.1.1 releases. A fastL4 UDP virtual server is using a fastL4 profile that has pva-offload-state set to establish.


Use default setting for pva-offload-state of embryonic for fastL4 profile.

Fix Information

With the fix in 12.1.2 and 13.0.0, ePVA will load UDP traffic when pva-offload-state set to establish.
