WCS error message

Which is the cause of this message?:

The AP 'XX:XX:XX:XX:XX:XX' received a WPA MIC error on protocol '1' from Station 'XX:XX:XX:XX:XX:XX'. Counter measures have been activated and traffic has been suspended for 60 seconds.

What can I do to resolve the problem?

Re: WCS error message

Looks like a device has failed the authentication to one of your wlans. The client then suspended for the 60 seconds which was configured. This feature is configured under the wlan in the client exclusion located in the advanced tab. If the client fails 3 times in a row, then the user will not be able to associate to the ap for a period that is set.

Re: WCS error message

Hi, I did not find the option client exclusion in the advanced tab. I have WLC version: 4.0.206.0.

In the version 4.0 where I can find this option?

Re: WCS error message

You will find this option under:

WLAN | SSID | Advanced

Should be on the bottom left side... If enabled, you should see 60 seconds.

Re: WCS error message

Hi fella5, I found the option that says, this option "Client Exclusion" is availble in:

WLAN|SSID|edit in the version of the Wireless Lan Controller version 4.0.206.0.

Client Exclusion |x| enable 60 Timeout Value (secs)

I will disable this option to correct the problem: "The AP 'XX:XX:XX:XX:XX:XX' received a WPA MIC error on protocol '1' from Station 'XX:XX:XX:XX:XX:XX'. Counter measures have been activated and traffic has been suspended for 60 seconds".

I will comment the process !!!

thanks fella5

Re: WCS error message

Are you using WPA-PSK with TKIP?
