RADIUS  
Overview 
The RADIUS configuration screen allows Administrators to modify information regarding RADIUS, or the 
Remote Authentication Dial-In User Service, an access server authentication, authorization, and accounting 
protocol developed by Livingston Enterprises, Inc. RADIUS protocol defines the communication between 
a RADIUS client and a RADIUS server. 
The RADIUS Configuration screen is used to set up the unit for use with a RADIUS protocol server. 
RADIUS protocol is an Internet standard that provides user authentication, authorization, and accounting 
services for remote access devices. Dominion SX can be configured as a RADIUS client. The unit will 
query the RADIUS server for authentication and authorization information each time a user attempts to 
login to the unit.  
The client is responsible for passing user information to designated RADIUS servers, and then acting on 
the response that is returned. RADIUS servers are responsible for receiving user connection requests, 
authenticating the user, and then returning all configuration information necessary for the client to deliver 
service to the user. 
 
 
Figure 59 RADIUS Users Login Mechanism 
RADIUS Authentication occurs when a user tries to log on to the RADIUS client. After prompting the user 
for login name and password, the client checks to see if the user is already present in the local list. If not, 
the client sends this information in an authentication request to the RADIUS server. The RADIUS server 
checks the validity of the request, then checks its database of user names and passwords. If the name or 
password are not valid, it sends a rejection to the client, who in turn rejects the login. If the login name and 
password are valid, the RADIUS server sends back a packet containing information about this user, and the 
client uses this information to decide what type of service to supply for the user.
