Cisco Cisco IOS Software Release 12.3(4)T

SSG must be enabled by using the ssg enable command before this feature can be configured.

The RADIUS server should be configured and operational when the SSG Unique Session ID feature is 
being used.

To configure the SSG Unique Session ID feature, you must understand the following concepts: 

The SSG is a switching solution for service providers who offer intranet, extranet, and Internet 
connections to subscribers using broadband access technology such as digital subscriber lines (DSL), 
cable modems, or wireless to allow simultaneous access to network services. It is a combined hardware 
and software solution that helps service providers provide differentiated kinds of services to users 
connecting through different mediums. SSG also offers user authentication and accounting features. 

Before the introduction of this feature, SSG did not support a unique accounting session ID in RADIUS 
accounting records. The SSG Unique Session ID feature adds the ability to create a unique RADIUS 
accounting session ID by appending the client’s IP address to the session number. The feature applies to 
accounting packets generated by SSG for host accounting or connection accounting records.

The SSG Unique Session ID feature is compatible with existing back-end billing systems and meets the 
requirements for the support of wide-area networks based on IEEE 802.11b technology. 

This section contains the following procedure:

session ID.
