To openthe Network Security page select Switch → Network Security.Network Security OverviewThis section describes the network security features.Port Based Authentication (802.1x)Port based authentication enables authenticating system users on a per-port basis via a externalserver. Only authenticated and approved system users can transmit and receive data. Ports areauthenticated via the RADIUS server using the Extensible Authentication Protocol (EAP).Port Authentication includes:• Authenticators — Specifies the port that is authenticated before permitting system access.• Supplicants — Specifies host connected to the authenticated port requesting to access the systemservices.• Authentication Server — Specifies the external server, for example, the RADIUS server thatperforms the authentication on behalf of the authenticator, and indicates whether the user isauthorized to access system services.Port based authentication creates two access states:• Controlled Access — Permits communication between the user and the system, if the user isauthorized.• Uncontrolled Access — Permits uncontrolled communication regardless of the port state.The device currently supports Port Based Authentication via RADIUS servers.
