![]() Once it is successfully authenticated we need to get an IP from X0:V190 subnet. ![]() The PC that needs be authenticated is connected to port 5 on the switch which is portshielded to interface X0. Please refer to Setting Up 802.1x Authentication On SonicWall Switch for 802.1X authentication related settings on the firewall and RADIUS server.ĮXAMPLE: Let us consider that the RADIUS server is connected to port 1 of the switch and has static IP: 192.168.181.100. The Switch uses 802.1X to enable or disable port access control, to enable or disable the Guest VLAN, and to enable or disable the forwarding EAPOL (Extensible Authentication Protocol over LANs) frames.Īdditionally, we can also have the VLAN assignment done through the RADIUS server itself. If the authentication server determines the credentials are valid, the supplicant (client device) is allowed to access resources located on the protected side of the network. ![]() With 802.1X authentication, the supplicant provides credentials, such as user name, password, or digital certificate to the authenticator, and the authenticator forwards the credentials to the authentication server for verification. The IEEE-802.1X authentication provides a security standard for network access control with RADIUS servers and holds a network port disconnected until authentication is completed.
