Authentication Through a RADIUS Server
To allow mobile users to access the Internet and selected services on your
company’s network, you configure Web-Auth(open) as the authentication
method for a WLAN and define a RADIUS server that verifies each user’s login
credentials. You can specify both a primary RADIUS server and a secondary
RADIUS server, ensuring high availability. If the primary RADIUS server is
unavailable, the Wireless Edge Services xl Module contacts the secondary
RADIUS server.
