What Cisco WLAN controller code are you running?
We are curious what Cisco WLAN controller code you are running (5508 controllers?) With the number of Windows 8 systems that are coming in the door from students, we are fairly certain that we are hitting this bug, which we have been resolving with client drivers CSCua29504 - 802.11w-capable client fails pairwise key handshake with AES. https://tools.cisco.com/bugsearch/bug/CSCua29504/?referring_site=ss Symptom: An 802.11w-capable client, such as a PC running Windows 8, cannot connect to an SSID using WPA or WPA2 key management with AES encryption. The AP will send the M1 pairwise key message, but the PC will never respond with M2. With debug client in effect, a message similar to the following will be seen: *dot1xMsgTask: Jun 12 20:23:37.471: 00:11:22:33:44:55 Retransmit failure for EAPOL-Key M1 to mobile 00:11:22:33:44:55, retransmit count 5, mscb deauth count 0 Conditions: Client is 802.11w-capable, wireless infrastructure is CUWN, SSID using WPA2/AES or WPA/AES. This bug affects CUWN 5.2.178.0 and above, but not CUWN 4.2 or earlier, nor does it affect autonomous IOS APs. Workaround: Use WPA/TKIP or WPA2/TKIP instead. Note that this will limit the client to 802.11g/802.11a data rates. Another workaround is to use a Windows 7, rather than Windows 8 driver, for the adapter.

Re: What Cisco WLAN controller code are you running?
Here we have six controllers on 7.4.110.0 and one on 7.4.100.60. We're having a hell of a time with mDNS that explains the one controller on difference code. Otherwise, upgrades into 7.4 were smooth as butter... Make sure you upgrade Prime and your MSEs, too... OK, one exception - I did need to remove and readd the MSE to Prime to get it working again after the upgrade to 7.4... but that was easy. -Rick On 8/29/2013 10:23 AM, John York wrote: +1.

Re: [WIRELESS-LAN] What Cisco WLAN controller code are you running?
We are running 7.2.111.3 on most of our controllers but have (4) new 5508's running 7.5.102.0 code for mDNS pilot testing and 802.11ac modules. We have also upgraded Prime to 1.4 and out MSE to 7.5 for compatibility. So far we have had issues with Prime versions 1.2 through 1.4 constantly crashing when adding floorplans. This requires a restart of the service on our server. We also see very sluggish performance from the GUI that we are working with TAC on. When Prime is running slow we see our disk IO times are very high and should not be based on the server this VM is on. So far the 7.5 code has been working as expected but we have not enabled the mDNS enhancements yet or any other features that are different from 7.2 code. -Jimmy Wireless Network Engineer University of Michigan - ITS Communications Systems and Data Centers On Thu, Aug 29, 2013 at 11:16 AM, Alan Nord an...@macalester.edu wrote: Running 7.2.111.3 for the past 3 months.

RE: [WIRELESS-LAN] What Cisco WLAN controller code are you running?
We upgraded our 5508 controllers to 7.4.110.0 code a couple of weeks ago, primarily to take advantage of the mDNS features. No reported problems so far but the real test will be when students get back. Had issues with mDNS/bonjour. From the iPads could see the AppleTVs but not from iPhones. From iPads could not mirror to any AppleTV. Opened a TAC case and issue was resolved by adding AirTunes as a service name - see attached screenshot. We have about 25+ AppleTV (wired) and all can now be mirrored to, from two different WLANs.

We can't seem to make that work reliably, either - but there I am beginning to suspect the papercut software isn't quite doing things right because we can make handiprint shared queues show through. It's not been fun working with cisco on this one... Aside from the mDNS, 7.4.110.0 seems fine... -Rick On 8/29/2013 11:58 AM, Mark Duling wrote: Hi Rick, What mdns issues are you seeing, and which version do you see it on? Has TAC been able to help? mdns worked pretty good on 7.4.100.6 (engineering build) for us and we went to 7.4.110.0 and immediately added a new WLAN. Not sure if it was the new code or adding the WLAN, but on the new WLAN mdns is squirrely. Some AppleTVs don't work at all if you're on the new WLAN, and others do. But get on the old WLAN and it works fine. The settings on the new and old WLANs are identical. It's baffling. Anyone else see issues like this on 7.4?

We're having a hell of a time with mDNS that explains the one controller on difference code. Otherwise, upgrades into 7.4 were smooth as butter... Make sure you upgrade Prime and your MSEs, too... OK, one exception - I did need to remove and readd the MSE to Prime to get it working again after the upgrade to 7.4... but that was easy. -Rick On 8/29/2013 10:23 AM, John York wrote: +1.

I thought this was a bug when Win 8 first came out and fixed in code 7.2.111.3, sometime around October 2012.
