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
