Thanks, Jess and Scott. It's pretty much always something on these WLCs, isn't it? The alerts with 4K APs would likely drive us batty and make PI hard to wade through the noise to real issues. I'm thinking no upgrade for a while...

Lee, I am also seeing what Scott is seeing with the nearly instantaneous radio resets on the 5Ghz side. It doesn't seem to affect any client experience, either, but it does generate a LOT of noise from a monitoring point of view. We have had a TAC open about this since February, but honestly haven't really done any hardcore troubleshooting of the issue once we ascertained that it was not affecting service in any real way. In Prime, I have it emailing a distribution group, and I get tons and tons of emails from the same exact time, one reading that the AP went down, and the other one reading that it came up, like so: __________________________________ PI has detected a change in one or more alarms of category AP and severity Critical in Virtual Domain ROOT-DOMAIN. The new severity of the following items is Clear: 1. Message: '802.11a/n' interface of AP 'OWS458-01-1142' associated to controller 'UST-WLC8510 (140.209.13.70)' is up.

The AP models we have are 1242's, 1142's, 2702's (both i's and e's), and 702W's. Also, we are just now going live with ISE 1.4 as well.

Hello to the group- for those of you who have moved to the Cisco-recommended 8.0.120.0 code, have you found any issues? Particularly big 8510 environments with thousands of APs per controller doing 802.1x/WPA2.
