Onlyauthenticated and approved system users can transmit and receive data. Ports are authenticated viathe RADIUS server using the Extensible Authentication Protocol (EAP). Port-based authenticationincludes:z Authenticators: Specifies the switch port which is authenticated before permitting system access.z Supplicants: Specifies the host connected to the authenticated port requesting to access thesystem services.z Authentication Server: Specifies the server that performs the authentication on behalf of theauthenticator, and indicates whether the supplicant is authorized to access system services.Port-based authentication creates two access states:z Controlled Access: Permits communication between the supplicant and the system, if thesupplicant is authorized.z Uncontrolled Access: Permits uncontrolled communication regardless of the port state.This section includes the following topics:z Defining 802.1X Authenticationz Viewing 802.1X Authentication
