Why Are 802.1x Authenticated Users Disconnected from the Network Immediately After They Go Online?

Fault symptom: A wireless 802.1x authentication device is associated with the Security Management Platform (SMP). After a user goes online on the SMP successfully, the user is disconnected from the network immediately. The prompts displayed on the AP show that the user goes offline actively because the four-way handshake fails.

Possible causes: Check authentication information on the SMP. No exception is found. Captured packets indicate that the authentication type configured on the AC is inconsistent with that on the SMP. The root cause is that wired 802.1x authentication is selected on the SMP.
