Defining Port-Based Authentication (802.1X)

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.
