5508 HA SSO ping timeout

[lcaruso]

Hi,

I recently implemented 5508 HA SSO pair running the latest FUS and 7.6.110.0 OS.

The HA Deployment Guide shows 0% ping loss for failover tests, but this pair of 5508s in production have shown up to two ping losses and are consistent for every failover test.

Since the guide makes clear the expectation that not even one ping should be dropped, any suggestions as to where to start looking for an issue. We followed the Deployment Guide instructions. Pings were to the Internet.

Thanks.

Well when testing, how are the pings on the local LAN or a continuous ping to the client?  If you have ping loss during internal LAN test, then there must be an issue.  I wouldn't test from the client to an internet IP.

Can you post the diagram of how you deployed the WLC and the relations to your internet getway?

sorry I'm just slammed right now with work and don't have time. I'll eventually open a TAC case and see if we can find anything on the controllers themselves contributing to the issue.
