Port-Based Authentication Overview
Port-based authentication enables authenticating system 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 Authentication
includes:
• Authenticators — Specifies the device port that is authenticated before
permitting system access.
•
Supplicants — Specifies the host connected to the authenticated port hat
is requesting to access the system services.
•
Authentication Server — Specifies the external server, for example, a
RADIUS server, which performs authentication on behalf of the
authenticator, and indicates whether the supplicant is authorized to access
system services.
