TKIP Countermeasure Holdoff Time
TKIP countermeasure mode can occur if the access point receives two message integrity check (MIC) errors within a 60 second
period. When this occurs, the access point will de-authenticate all TKIP clients associated to that 802.11 radio and holdoff any
clients for the countermeasure holdoff time (default = 60 seconds).
To change the TKIP countermeasure holdoff time on the Cisco Unified Wireless LAN Controller, telnet or SSH to the
controller and enter the following command:
(Cisco Controller) >config wlan security tkip hold-down <nseconds> <wlan-id>
To confirm the change, enter
show wlan <WLAN id> , where the following will be displayed.
