System Diagnostics
Some possible controller inference messages are:
9Key Exchange Failure
Station exceeded threshold of 802.1x key exchange attempts. An AP
detected either of the following conditions of 1X authentication
failure between the AP and the client;
 EAPoL handshaking failed
 EAPoL handshaking timed out
Another possible cause is that Hostapd detected one of the following
conditions of 1X authentication and 802.1x key exchange failure:
 Invalid Radius VLAN tag detected
 EAP packet failed to reach the station
 MIC failure occurred and both the counts of MIC failure and 802.1x
key exchange failure are increased
 4-way handshake timed out
 Group key update timed out
 EAP key replay counter is mismatched
10 MIC Failure Station exceeded threshold of 802.1x MIC attempts
11 802.1x Radius Success Station executed 802.1x Radius authentication
12 802.1x Radius Failure Station exceeded threshold of 802.1x Radius authentication attempts
13 IP Address Update IP address changed from valid to 0, 0 to valid, or valid to valid
14 Data Decryption Failure
Data decryption failure of RX packet occurred; attempt threshold was
exceeded. Hostapd detected that
Ess.MicCountermeasureData.MicCounter exceeded 1 within the
MIC_COUNTERMEASURE_PERIOD (60 seconds). When this occurs,
Hostapd notifies the AP to stop accepting communication from that
station and disassociate the station.
15 CP Guest User Success Station authenticated a Captive-Portal guest
16 CP Guest User Failure
Station exceeded threshold of Captive-Portal guest authentication
attempts
17 CP Radius User Success Station authenticated Captive-Portal user using Radius
18 CP Radius User Failure
Station exceeded threshold of Captive-Portal Radius user
authentication attempts
19 Soft-Handoff Station executed soft-handoff
