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.
