The client requires IEEE 802.1X compatible software (An IEEE 802.1X supportedclient is called Supplicant). The client sends an authentication request whenconnecting to the network and is able to access when authorized. The authentication Switching Hub intermediates an authentication processbetween the client and authentication server. It blocks connections to thenetwork from unauthorized clients (The authentication Switching Hub is alsocalled Authenticator). This Switching Hub allows you to enable/disableauthentication for each port and configure the authentication settings. A RADIUS server is usually used for the authentication server. It only approves anauthentication request from registered users. Up to three authentication serverscan be registered in the authentication Switching Hub.
