From a colleague: 1. Running 8.1.111.0 2. I’ve noticed that when the APs reboot, sometimes APs won’t join the controller. 3. The command “sh cdp n detail” shows all normal and the APs are getting the correct IP address; 4. However, the output of “sh interface <PORT>” only shows one-way-traffic: From the switch to the AP and nothing coming back from the AP; 5. AP refuses to join the controller; 6. If I console into the AP I will see a lot of newly-generated crash logs pointing to the corruption of the radio drivers. I do NOT understand how the corruption of radio drivers preventing the AP from joining the controller. 7. The AP did NOT boot into ROMmon; 8. If I delete the IOS and force the AP to boot the recovery image, the AP will join properly. TAC told him this is a known bug that WAS NOT fixed on .120, but would be on the next MR release around November. You may want to hold out for that one. -Lee Lee Badman | Network Architect Information Technology Services 206 Machinery Hall 120 Smith Drive Syracuse, New York 13244 t 315.443.3003 f 315.443.4325 e lhbad...@syr.edu<mailto:lhbad...@syr.edu> w its.syr.edu<http://its.syr.edu/> SYRACUSE UNIVERSITY syr.edu<http://syr.edu/> From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU] On Behalf Of Cosgrove, John Sent: Monday, August 31, 2015 11:22 AM To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU<mailto:WIRELESS-LAN@listserv.educause.edu> Subject: Re: [WIRELESS-LAN] Cisco WLC 8.0.120.0 (MR2) on 8510- good, bad?

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 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.
