ISG Support for SAMI Blade
ISG Support for SAMI Blade
Last Updated: November 30, 2011
The ISG Support for SAMI Blade feature combines the subscriber management features and functions of the Cisco Intelligent Services Gateway (ISG) with the processing power of the Cisco Service Application Module for IP (SAMI). The Cisco SAMI blade has six PowerPC (PPC) processors and occupies just one slot in the Cisco 7600 series router. This means that you can support many ISG features for up to 600,000 subscribers on a single router.

Information About ISG Support for SAMI Blade
The Cisco SAMI blade has no external physical interface to receive traffic to and from subscribers. It is connected to the switch fabric in the Cisco 7600 series router chassis and an internal Gigabit Ethernet port provides an interface between it and the supervisor module.
You must configure each of the six SAMI PPCs independently of the others on the SAMI blade. To configure the ISG Support for SAMI Blade feature, you should understand how to configure ISG access for IP subscriber sessions. For more information, see the "Configuring ISG Access for IP Subscriber Sessions" chapter of the Cisco IOS Intelligent Services Gateway Configuration Guide.
You should also understand the following concept:
You must configure and assign virtual LANs (VLANs) from the supervisor engine to the Cisco SAMI blade so that you can create and configure subinterfaces on each PPC GigabitEthernet0/0 single logical port. You can then enable ISG on those subinterfaces to perform IP-based subscriber management functions.
For more information, see the "Maintaining and Monitoring the Cisco SAMI" and "Configuring VLAN Support" sections of the Cisco Service and Application Module for IP User Guide.
