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.

+1. We're also on 7.2.111.3 and wondering if it's time to upgrade. Is
there a nice, stable new release for the 5508? I'm still gun shy from
the 4400 days, when an upgrade often meant lost weekends and tearing
out of hair.

7.2.111.3 is what we are on, and have stayed there because it has been
stable for us. Just wondering if we should jump to 7.4.110.0 or some
other code...

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

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.
Thanks,
Erik
