Port Authentication 15-1
This chapter describes the 802.1x authentication method and RADIUS server connection setup.
15.1 Introduction to Authentication
IEEE 802.1x is an extended authentication protocol

that allows support of RADIUS (Remote Authentication Dial
In User Service, RFC 2138, 2139) for centralized user profile management on a network RADIUS server.
15.1.1 RADIUS
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
To enable port authentication, first activate IEEE802.1x security (both on the ES-3124 and the port(s)) then
configure the RADIUS server settings.
Click Port Authentication under Advanced Application in the navigation panel to display the screen as shown.

Not all Windows operating systems support IEEE 802.1X (see the Microsoft web site for details). For other operating
systems, see its documentation. If your operating system does not support IEEE 802.1X, then you may need to install IEEE
802.1X client software.
