Fixed In:
14.1.4

Opened: Mar 30, 2020

Severity: 3-Major

Symptoms

TCP connections are hardware accelerated for both client- and server-side traffic, but there is no way to specify the TCP hardware acceleration for only client-side or only server-side traffic.

Impact

This change allows you to specify TCP hardware acceleration for only client-side traffic, only server-side traffic, or both. Both is the default behavior. Note that setting TCP directional offload based on this change is global. There is no per-Fast L4 profile setting.

Conditions

The BIG-IP device has TCP hardware accelerated flows.

Workaround

None.
