Any update on the bug fix for the flapping 5ghz radios in 8.0.120? I'm seeing a fair amount of them on my 3702i's. 

Thanks!

Hi Lee,
The 5 GHz radio message is a DFS problem and part of bug (CSCut98006)-and (CSCuq86269)
CSCut98006 DFS detections due to high energy profile signature – AP2600/3600 specific fix 

Fixed in Image  8.0.110.22 for 3600/2600 platforms
For 1700/2700/3700 will be coming soon, as there were some minor issues found during fix porting for this HW that are being resolved.
This week Cisco should be able to confirm ETA for this second part of the fix
(this is my TAC case SR 634977857 Flapping AP radio causing Alarms in Prime)

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:

In fact, here, the "all clear" message arrived before the one telling about the down event, and both are timestamped for 4:21PM. :-)
Our environment is an 8510 HA pair running 8.0.120.0 for the larger campus with 900 or so APs, and an 5508 HA pair running 8.0.120.0 for the smaller campus with under 200 APs, and Prime 2.2. 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.

    My environment is not on that scale, but I’m still seeing a lot
    of 5GHz radios cycling between up and down states followed by a
    reset, then it will come back up. Might happen again later, might
    not. Seems to be happening on all models.

    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.

    Thanks-
