Occasionally MIC failures can occur
during key rotation. To diagnose the
problem, you should:
• Check the IOS version.
• Enable 802.1x logs on the AP.
• Perform an SNMP walk of
cDot11WidsProtectFailClientTa
ble to determine which clients
are reporting the TKIP MIC
failure. If just one client is
reporting the failure, it could be
a client issue
