VPI/VCI Static Binding to a Service Profile

The VPI/VCI Static Binding to a Service Profile feature allows users accessing SSG through a VPI/VCI or a range of VPI/VCIs to access the server. When a user session arrives on a VPI/VCI or a VPI/VCI range and the session specifies the username but does not specify the domain name, SSG maps the user session to the service to which the VPI/VCI or VPI/VCI range is bound.

For more information, refer to the”Configuring VPI/VCI Indexing to Service Profile” section in the Node Route Processor—Service Selection Gateway Enhancements, Release 12.0(5)DC feature module.

Restrictions for VPI/VCI Static Binding to a Service Profile

The VPI/VCI Static Binding to a Service Profile feature has the following restrictions:

•The feature applies only to PPP sessions.

•You must statically configure the feature.

•SESM cannot map the VC to the service.

Configuration of VPI/VCI Static Binding to a Service Profile

To map a VC to a service, use the ssg vc-service-mapcommand in global configuration mode. For more information, refer to the ”Broadband Access: Service Selection Gateway Commands” section in the Cisco IOS Wide-Area Networking Command Reference, Release 12.2T.
