RADIUS (Remote Authentication Dial-In User Service) authentication is a popular protocol used to authenticate
users by means of an external server instead of (or in addition to) an internal device user database that is limited to
the memory capacity of the device. In essence, RADIUS authentication allows you to validate an unlimited
number of users from a central location.

15.2 Configuring Port Authentication

At the time of writing, only Windows XP of the Microsoft operating systems supports it. See the Microsoft web site for
information on other Windows operating system support. For other operating systems, see its documentation. If your
operating system does not support 802.1x, then you may need to install 802.1x client software.
