Remote Authentication Dial-In User Service (RADIUS) is a security authentication
client/server protocol that supports authentication, authorization and accounting, which is
widely used by Internet service providers. It is the most common method of authenticating
and authorizing dial-up and tunneled network users.
The built-in RADIUS client feature enables the router to assist the remote dial-in user or a
wireless station and the RADIUS server in performing mutual authentication. It enables
centralized remote access authentication for network management.
