Network Access Server configuration is useful to the networking environment that wants to authenticate clients
(supplicants) before they can access resources on the protected network. To effectively control access to unknown
clients, 802.1X defined by IEEE provides a port-based authentication procedure that can prevent unauthorized access
to a network by requiring users to first submit credentials for authentication purposes.
A switch interconnecting clients and radius server usually acts as an authenticator and uses EAPOL (Extensible
Authentication Protocol over LANs) to exchange authentication protocol messages with clients and a remote RADIUS
authentication server to verify user identity and user’s access right. This section is for setting up authenticator’s
configurations either on the system or on a per port basis. To configure backend server, please go to RADIUS
configuration page.
