report from the station [mac-address] on the packet (TSC=0x0) encrypted and
protected by [key] key
Explanation The access point received an EAPOL-key from the indicated station notifying the access
point that TKIP Michael MIC failed on a packet transmitted by this access point.
Recommended Action None.
Error Message DOT11-3-TKIP_MIC_FAILURE_REPEATED: Two TKIP Michael MIC failures were
detected within [number] seconds on [interface] interface. The interface will be
put on MIC failure hold state for next [number] seconds
Explanation Two TKIP Michael MIC failures were detected within the indicated time on the
indicated interface. Because this usually indicates an active attack on your network, the interface
will be put on hold for the indicated time. During this hold time, stations using TKIP ciphers are
disassociated and cannot reassociate until the hold time ends. At the end of the hold time, the
interface operates normally.
Recommended Action MIC failures usually indicate an active attack on your network. Search for and
remove potential rogue devices from your wireless LAN. If this is a false alarm and the interface
should not be on hold this long, use the countermeasure tkip hold-time command to adjust the hold
time.
