WCS error message

[ricardorojas123]

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?

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.

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?

[Scott Fella]

You will find this option under:

WLAN | SSID | Advanced

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

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

I have the client exclusion policy disabled on the WLAN and I still receive this MIC errors about daily. Any other suggestions?

What MIC errors are you seeing?

[kwoerner1]

The AP xx:xx:xx... received a WPA MIC error on protocol '0' from Station xx:xx:xx:... Counter measures have been activated and traffic has been suspended for 60 seconds.

The clients are always a Vocera B2000 Badge.

Are you using WPA-PSK with TKIP?
