If handshake with online 802.1x users is enabled on a switch, the switch periodically sends handshake packets to a user client after the client is authenticated. If the client sends no handshake packet to the switch, the switch forces the user offline.

The user goes offline 10 seconds after being authenticated. This may be caused by a handshake failure.

To solve this problem, run the undo dot1x handshake command to disable the handshake function.
