Device Roles
With IEEE 802.1x port-based authentication, the devices in the network have specific rol es as shown in
Figure 9-1.
Figure9-1 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. (T he c lient is t he
supplicant in the IEEE 802.1x standard.)
Note To resolve Windows XP network connectivity and IEEE 802.1x authentication issues, read
the Microsoft Knowledge Base article at this URL:

•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
