detected within [number] seconds on [interface] interface. The interface will be 
put on MIC failure hold state for next [number] seconds

Explanation    Because MIC failures usually indicate an active attack on your network, the interface will be put on hold for the configured time. During this hold time, stations using TKIP ciphers are disassociatedand cannot reassociate until the hold time ends. At the end of the hold time, the interface operates normally.
