iRule after upgrading 9.1.X to 9.3.x

according to my support vendor(in Tokyo, Japan), after upgrading to version 9.3.1, you still need to apply HF1 if you are using SSL session ID persistence.

 

it's reported that SSL session ID persistence breaks on LTM 9.3.x. unless you install the hot fix.

 

 

Futhermore,even upgrading to v9.3.1 + HF1, the LTM might still have problems or know issues with Network Failover in HA configuration that is in a Active-Standby configuration, failover takes about 40 seconds , so if your HA pair is in an environment where 40 seconds is untolerable,don't setup Network Failover.

 

 

Sako.
