802.1x Port Security Overview
802.1x port security requires a user connected to a port in the network to be authenticated by an authentication server.
When a user connects to a port configured with 802.1x port security, the port forwards an authentication request to a RADIUS authentication server. The authentication server checks if the user is authorized to use the port, and either allows or blocks access to the port.
The port can be configured to reauthenticate the user. If the reauthentication fails, the user is denied further access to the port.
