We have a WISM blade with two controllers enabled. Single mobility group and no AP groups. We keep having random disconects when our users are in Citrix. Some sugestions I read say that I should enable CCKM. We turned on 802.1x+CCKM on one controller and it seems to work. When we turned on only CCKM mode we can no longer associate clients to any APs on that controller. When would you use CCKM only and when 802.1x+CCKM mode of key mgmt is preffered?
if you select 802.1x + CCKM, both 802.1x and CCKM compatible clients will be able to associate and authenticate. This is the preferred option if you are in a mixed environment (devices supporting and not supporting CCKM).
If you devices cannot associate to the WLAN network when only CCKM is selected, this means that these devices are not CCKM capable.
Another way to verify this is by using the following command on the controller (via telnet):
show pmk-cache summary
Please note that both the driver and the supplicant used need to support CCKM. the windows supplicant for example (Wireless Zero Config) does not support CCKM.
Also, there are a lot of issues with the Intel Pro Set cards. Best it to use a Cisco card with the Cisco utility, at least for the tests.
Thanks for your reply. show pmk-cache sum on my test controller tells me that there is no such command. I can do show pmk-cache all and I see a list of MACs. If I do this command on my controller that has all the APs on it - it shows the same list of MACs. Does 802.1x do the same caching as CCKM?

This is the start of a display filter cross reference between Wireshark and OmniPeek.
The 1st installment is a table of advanced filters. More filters will be added as time allows.

The script should be completely self explanatory.
