Defining Port-Based Authentication (802.1X)
Port-based authentication authenticates users on a per-port basis via an external server. Only
authenticated and approved system users can transmit and receive data. Ports are authenticated via
the RADIUS server using the Extensible Authentication Protocol (EAP). Port-based authentication
includes:
Authenticators: Specifies the switch 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.
