FWIW, I know you specifically mentioned 7.3 and 7.4, but we ran 7.5 for
several weeks in a SSO HA configuration between a pair of WiSM2's in a
6500 with Sup720's and had no issues. It was handling ~600 AP's and a
couple thousand concurrent users.

I was wondering if anyone was running WiSM2's that are paired with an
HA SKU model doing AP-SSO.
We have had issues with our WiSM2's failing over to the HA peer
randomly. This has happened in both 7.3 and 7.4 versions. We have seen
a couple of different error messages in prime when this happens. One
was regarding the WiSM2 not being able to reach the gateway, the other
said that the WiSM2 could not reach it's peer. This happens during off
peak times as well.
We have three different pairs, and we have seen this issue with all of
them, they are all in separate 6500 chassis, so I don't think that it
is a chassis specific issue, or specific to one WiSM2 in particular.
Two of the WiSMs have 900+ APs, the third has about 300, so it doesn't
seem to be load related.
Has anyone had a similar experience and found a fix, or is anyone
running this successfully without any issues? I dug up a couple of
posts on the Cisco forums, but they don't outline a fix.
We do have a TAC case open and we are trying to get it escalated to
level 2, this hasn't turned up much yet.
Thanks.
