Defining Port-Based Authentication (802.1X) 57

Defining Port-Based	Port-based authentication authenticates users on a per-port basis via an
Authentication	external server. Only authenticated and approved system users can
(802.1X)	transmit and receive data. Ports are authenticated via the RADIUS server
	using the Extensible Authentication Protocol (EAP). Port-based
	authentication includes:
	■ Authenticators — Specifies the device port which is authenticated
	before permitting system access.
	■ Supplicants — Specifies the host connected to the authenticated
	port requesting to access the system services.
	■ Authentication Server — Specifies the server that performs the
	authentication on behalf of the authenticator, and indicates whether
	the supplicant is authorized to access system services.
	Port-based authentication creates two access states:
	■ Controlled Access — Permits communication between the
	supplicant and the system, if the supplicant is authorized.
	■ Uncontrolled Access — Permits uncontrolled communication
	regardless of the port state.
