11.9 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.
11.9.1 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.
