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 which 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 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. The device currently supports Port Based Authentication via RADIUS servers. Advanced Port Based Authentication Advanced Port Based Authentication: • Enables multiple hosts to be attached to a single port. • Requires only one host to be authorized for all hosts to have system access. If the port is unauthorized, all attached hosts are denied access to the network. Configuring Switch Information 225
