Windows XP supports 802.1x with MD5 or TLS authentication. In this appen- dix, the following sections will discuss 802.1x configuration for PCs running Windows XP. If you are using MD5 authentication, proceed to “MD5 Authentication for Windows XP.” If you are using TLS authentication, go to the appropriate section, “Digital Certificate Installation” or “TLS Authentication for Windows XP,” depending on whether or not you have already installed a digital certificate on your PC.

If your PC is not running Windows XP, then your PC must use third-party 802.1x client software. For instructions on how to configure 802.1x through third-party software, refer to that application’s documentation.
