Just wanted to add my $.02. We are migrating from Cisco ACE to F5's. Mix of Viprion's and appliances. Running 11.6.1 HF1. Have had two cases now where a week plus after converting apps over to F5 (F5 is the layer 3 gw for the servers btw), they started having performance problems. Seemed to be only physical servers, with multiple nics and using teaming (HP servers).

 

I noticed that servers that were working fine must have been configured for NFT (use only one nic at a time) because their mac never changed, and they had no issues. Servers that were using multiple nics simultaneously, had problems.

 

Found this thread and disabled auto last hop on the server side vlan only and it immediately resolved the issue.

 

Thanks everyone.
