Description (partial)


With WLC version 4.1 and later, there is a command to change the scan time for MIC errors. The command is "config wlan security tkip hold-down <0-60 seconds> <wlan id>". We can use the value 0 in order to disable MIC failure detection for countermeasures.

However after rebooting the WLC this value goes back to the default value of 60, even saving the config before reboot.


Config WLC with  "config wlan security tkip hold-down <0-60 seconds> <wlan id>", save configuration and reboot.
After the reboot the value reverts to the default 60 secs.
