Unstable with Virtual Servers when running Active/Standby F5 Big-IP LTM 3600 ver 11.1

Hi nitass,

 

 

Unit 01 is using LTM&ASM module (has license LTM&ASM)

 

while Unit 02 is using LTM module (just has license for LTM)

 

 

The Failover State very unstable, it's often disconnect and reconnect frequently so the role is also switchover (Active<->Standby) with each other frequently too. Therefore, the virtual servers: 10.6.1.10 can't access from outside at that time.

 

 

This is the local traffic log from the Standby Unit:

 

=====================================

The problem mayble related to the MAC Masquerade Address. Do you think so, Nitass?
