Cisco Cisco IOS Software Release 12.4(22)XR

This section discusses concepts related to single IP Infrastructure and Manageability requirements for 
the Service Provider PDSN gateway application. This application is resident on the SAMI service blade 
of the Cisco 7600 Series Router and is part of the Mobile Internet product family. This section also 
provides details about how to configure this feature.

This section includes the following sub sections:

The current Mobile Internet gateway-on-SAMI solutions, (WiMax ASNGW, GGSN, and PDSN except 
HA) all offer a multiple-routers-on-a-stick model with the attendant manageability and operational 
issues. The system design for PDSN single IP allows you to manage the gateway-on-SAMI on a 
per-blade basis. This results in a “factor-of-6 decrease” in operational complexity compared to the 
previous presentation of six individual processors per blade.

Here is an additional targeted subset of functionality that is presented in a per-chassis model. The 
presentation of a per-blade model applies to the following areas:

AAA interactions

Network Management interaction through SNMP for MIB retrieval
