4.1.7 802.1X Configuration
IEEE802.1X provides a security standard for network access control, especially in Wi-Fi
wireless networks. 802.1X holds a network port disconnected until authentication is completed.
The switch uses Extensible Authentication Protocol over LANS to exchange authentication
protocol client identity with the client, and forward it to another remote RADIUS authentication
server to verify access rights. The EAP packet from the RADIUS server also contains the
authentication method to be used. The client can reject the authentication method and request
another, depending on the configuration of the client software and the RADIUS server.
Depending on the authenticated results, the port is either made available to the user or the
user is denied access to the network.
