hello,
I have a wireless network built with Cisco WLC 5520 (in HA), AP 2800. WLC is running code 8.3.133.0.
Randomly, client roaming goes wrong, all I can found in the debug client is this :
xx:xx:xx:xx:xx:xx : MAC of client
yy:yy:yy:yy:yy:yy : BSSID
*Dot1x_NW_MsgTask_2: Nov 22 09:52:43.707: [PA] xx:xx:xx:xx:xx:xx Received EAPOL-Key from mobile xx:xx:xx:xx:xx:xx

hello,
I think somehow the client send eapol pkt with the key version 1 that's ignored by the controller (version 2).
is there a way to ignore the version check in the controller ?
