Sometimes when I connect to 877W router via WiFi Im getting notice (which mentioned on cisco.com site) in logs:
%DOT11-7-CCKM_AUTH_FAILED : Station [enet] CCKM authentication failed
official explanation is: "The station has failed CCKM authentication."
And "Recommended Action" is: "Verify the topology of the APs under the WDS domain."
But 877W does not support WDS commands. And also there no ability to turn CCKM off.
Only one thing helps: reload.
I tried and made some tests with following IOSs:
I was using 3 different PC's (two XP's and one OSX Leopard, all of them were with latest updates/patches)
To confirm highly mentioned problem its enough to switch reauth period to 10 seconds:
dot1x reauth-period 10
And after few minutes we'll get many notices like:
%DOT11-7-CCKM_AUTH_FAILED: Station [enet] authentication failed
And all clients which are trying to reassociate or associate with 877w are unable to connect.
I was surfing through forum and noticed following steps for testing:
- to leave only one SSID
- to turn guest-mode off
- to turn off TKIP and allow only AES.
I tried everything and that was useless.
Maybe someone got any idea how to solve this problem?
