Port Based Authentication (802.1x)
Port based authentication enables authenticating system users on a per-port basis via a 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
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
system services.
•
Authentication Server — Specifies the external server, for example, the RADIUS server that
performs the authentication on behalf of the authenticator, and indicates whether the user is
authorized to access system services.
Port based authentication creates two access states:
•
Controlled Access — Permits communication between the user and the system, if the user is
authorized.
•
Uncontrolled Access — Permits uncontrolled communication regardless of the port state.
