I've searched for the following errors but cant find anything on the MFP Invalid Sequence Number error
I have just enabled Management Frame Protection (MFP) under AP Authentication / Wireless Protection Ploicies. Since then I have seen the follwoing MFP related errors on WCS.
MFP Anomaly Detected - 11 'Invalid Sequence Number' violation(s) have originated from the AP with BSS '00:11:20:8e:91:50'. This was detected by the radio with Slot ID '0' of the AP with MAC '00:1a:e3:76:fd:50' when observing 'Deauthentication' frames.
MFP Anomaly Detected - 20 'No MIC' violation(s) have originated from the AP with BSS '00:26:cb:ac:7e:71'. This was detected by the radio with Slot ID '0' of the AP with MAC '00:26:cb:d1:b2:b0' when observing 'Deauthentication' frames.
The WLC's are running 126.96.36.199 and WCS is on 188.8.131.52.
My question is what do these errors refer toand how do I get rid of them?? What caveats are there for impleementing this globally or on a per WLAN basis?
