What version of wlc code and ise are you using? -----Original Message----- From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:[email protected]] On Behalf Of Eric T. Barnett Sent: Wednesday, August 27, 2014 2:12 PM To: [email protected] Subject: [WIRELESS-LAN] Authentication failures at peak times (Cisco) We've got a relatively small deployment compared to many on this list, but we've run into a problem we just can't put our finger on. We're using 5508s and ISE as a RADIUS server and we're having HUGE latencies on WPA2-Enterprise PEAP authentication. There's times when almost no one can authenticate. What's really weird is that the controllers show "AAA Authentication Error" when this happens even though the username and password is correct. None of the devices seem distressed and there's no network problems we can see. Anyone ever seen this before or have any ideas how to troubleshoot? TAC so far has been not incredibly useful but they have only been on the case for a day or so now. I can hear my users sharpening the pitchforks...
