Opened: May 10, 2016

Severity: 3-Major

Symptoms

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.

Impact

Performance degradation.

Conditions

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.

Workaround

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

Fix Information
