SSG Mobile Wireless Enhancements

12.4(15)T

The Service Selection Gateway (SSG) is a Cisco IOS 
software feature set, supported on multiple platforms, that 
works with the Cisco Subscriber Edge Services Manager 
(SESM) and other components to provide a subscriber edge 
services solution. It implements Layer 3 service selection 
through selective routing of IP packets to destination 
networks on a per subscriber basis. SSG authenticates users, 
who are accessing the SSG services, based on the RADIUS 
access request received from the SESM or from the 
downstream device such as GGSN/PDSN.

The SSG Mobile Wireless Enhancements feature describes 
additional functionality enhancements including 
accounting-on-off suppression, accounting-start ignore 
configuration, and Packet of Disconnect (PoD) forwarding 
to the Network Access Server (NAS).

The following commands were introduced or modified by 
this feature: forward accounting-on-off, 
session-identifier.
