Bug ID 649914: Auto reselect does not work for cookie persistence

Last Modified: Oct 17, 2023

Affected Product(s):
BIG-IP LTM(all modules)

Known Affected Versions:
13.0.0

Fixed In:
13.0.0 HF1

Opened: Mar 08, 2017

Severity: 3-Major

Symptoms

A connection failure occurs when a pool member picked by cookie persistence goes down.

Impact

Connection failure. The BIG-IP system tries to persist to the pool member that's down.

Conditions

-- Configure cookie persistence. -- Make a connection to get a cookie. -- Force the pool member down. -- Make a connection with the same cookie.

Workaround

None.

Fix Information

Auto reselection for cookie persistence now works when a pool member picked by cookie persistence goes down, so there is no longer a connection failure.

Behavior Change

Previous behavior: The cookie is not deleted when reselecting a pool member. New behavior: The BIG-IP system removes cookie persistence for the server-side traffic when pool-member reselect fails (e.g., Connection Limit)
