Chapter 13 - Using SMS2000 with a
RADIUS Server
SMS2000 can authenticate subscribers and send accounting messages using RADIUS.
Beginning with the 2.3.6 release of SMS software, many RADIUS attributes and
additional features have been added.
For example:
• Add multiple RADIUS servers for fault-tolerance
• Add Alias IP addresses for clustered RADIUS Servers
• Configure retransmission, deadtime, and timeout timers
• Support RADIUS ports 1812 and 1813 for RADIUS request and accounting ports
(per official RADIUS assigned ports)
• Support Session-Timeout attribute
• Support Idle-Timeout attribute
• Set the NAS type parameter
See Chapter 5 for details on using the auth add radius and set nas-port-type
commands.
Configuring RADIUS
SMS2000 is designed to operate with standard RADIUS authorization and accounting
services. SMS2000 contains a RADIUS client that functions as if the SMS2000 were a
dial-in network access server. RADIUS authentication is an option instead of the OCS for
network providers that already have RADIUS servers and databases. The RADIUS
server is free software available for UNIX systems.
Obtaining the RADIUS Server Software
A variety of RADIUS servers are available. Once such server is FreeRADIUS, a
RADIUS sever for the Linux operating system. More information on FreeRADIUS is
