Radius Attributes - Nomadix AG-2000W User Manual

RADIUS Attributes

RADIUS (Remote Authentication Dial-In User Service) was originally created to
allow remote authentication to the dial-in networks of corporations and dial-up ISPs.
It is defined and standardized by the IETF (Internet Engineering Task Force) and
several RADIUS server packages exist in both the public domain and for commercial
sale.
RADIUS software stores a database of attributes about their valid subscriber base.
For example, usernames, passwords, access privileges, account limits and subscriber
attributes can all be stored in a RADIUS database. RADIUS works in conjunctions
with NAS (Network Access Server) devices to determine if access to the service
network should be granted, and if so, with what privileges.
When a subscriber attempts to access the service provider's network, the AG-2000w
delivers a Web page to the subscriber asking for a login name and password. This
information (password) is encrypted and sent across the network to the ISP's
RADIUS server. The RADIUS server decrypts the information and compares it
against its list of valid users. If the subscriber can be authenticated, the RADIUS
server replies to the AG-2000w with a message instructing it to grant access to the
subscriber.
