The SSG Service Profile Caching feature enhances the authentication process for Service Selection 
Gateway services by allowing users to authenticate a service using the service profile cached in SSG. 

When SSG Service Profile Caching is not enabled, an authentication, authorization, and 
accounting (AAA) transaction is required to download a service profile each time an SSG subscriber 
logs onto the service. The other SSG subscribers already logged onto the service also have their service 
parameters automatically refreshed as a result of this AAA transaction. In many cases, this automatic 
refresh causes unnecessary traffic in SSG and on the AAA server. 

Use Cisco Feature Navigator to find information about platform support and Cisco IOS software image 
support. Access Cisco Feature Navigator at
