IEEE 802.1x Device Roles
Client—the device (workstation) that requests access to the LAN and switch services and responds
to requests from the switch. The workstation must be running IEEE 802.1x-compliant client
software such as that offered in the Microsoft Windows XP operating system. (The client is the
supplicant in the IEEE 802.1x standard.)

Authentication server—performs the actual authentication of the client. The authentication server
validates the identity of the client and notifies the switch whether or not the client is authorized to
access the LAN and switch services. Because the switch acts as the proxy, the authentication service
is transparent to the client. In this release, the RADIUS security system with Extensible
Authentication Protocol (EAP) extensions is the only supported authentication server. It is available
