WLC MFP Error Message

Does anyone happen to have any information on this WLC error:

MFP Anomaly Detected - 6 'Invalid Sequence Number' violation(s) have originated from the AP with BSS

'00:1a:30:b9:4f:c2'. This was detected by the radio with Slot ID '0' of the AP with MAC '00:1a:30:b9:aa:e0' when

observing 'Deauthentication' frames.

Thanks

Re: WLC MFP Error Message

MFPs are signatures on the management frames of the access point. This message means there has been errors in the signing of some messages from neighbor APs.

This can either mean an attack (someone trying to spoof your AP), but most likely it's one of the few bugs on the topic that are hitting the WLC.

This got partly resolved on the current 7.0 code and will be completely fixed in the next 7.0.

Nothing to be alarmed about, it's a notification.
