Cisco Cisco Physical Access Reader Module

The MGF interface enables the Cisco ISM-SRE or the SM-SRE to communicate with one or more SMs 
installed in the host router. This interface is an internal Gigabit Ethernet interface using a High-Speed 
Intrachassis Module Interconnect (HIMI) connection to the router’s MGF, providing a logical connection 
between SMs. Configuration of the MGF interface is performed from the Cisco IOS CLI. The 
Cisco-authorized application running on the Cisco ISM-SRE or the SM-SRE manages the connections. 
For more information on configuring the MGF, see the 

 chapter of the 

The external service-module interface can be used to monitor LAN traffic. You can also select the 
external interface as the management interface for the SM. The external interface cannot be used for 
downloading applications.

Visible only to the SM software on the Cisco SM-SRE, the external service-module interface is the 
Gigabit Ethernet interface connector on the Cisco SM-SRE faceplate. The external interface supports 
data requests and data transfers from outside sources, and it provides direct connectivity to the LAN 
through an RJ-45 connector. 

This section describes how to configure basic network parameters for the SM using the Cisco IOS CLI.

This section contains the following tasks:

If you lose power or connection during any of the following procedures, the system usually detects the 
interruption and tries to recover. If it fails to recover, reinstall the system using the boothelper. 

Your first configuration task is to set up the internal interface between the Cisco ISM-SRE or SM-SRE 
module and the host router, which then enables you to access the SM to install and configure Cisco 
applications. 

To configure the Cisco ISM-SRE or SM-SRE interface to the host router, complete the following steps.
