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 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.
