Why does a client go offline 10 seconds after it passes 802.1x authentication on the switch

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

The client goes offline 10 seconds after it is authenticated. This may be caused by a handshake failure. In this case, run the undo dot1x handshake command in the system view to disable the handshake function.
