Cisco SRE Internal Service Modules Configuration Guide
First Published: October 2, 2009
The Cisco Services Ready Engine Internal Service Module (ISM-SRE family of devices) for the Cisco Integrated Services Router Generation 2 enables the routers to host Cisco, third-party, and custom applications. SRE modules have their own processors, storage, network interfaces, and memory that operate independently of the host router resources, helping to ensure maximum concurrent routing and application performance. A service-ready deployment model enables branch-office applications to be provisioned remotely on the modules at any time. The ISM-SRE also supports Cisco Software Licensing (CSL) and Pay-as-you-Grow (PAY-GO) features.

Prerequisites for the Cisco ISM-SRE
Router
•Plan software upgrades or downgrades for times when you can take all applications that run on the host router out of service or offline.
•Ensure that you have the appropriate Cisco Integrated Services Router Generation 2 (ISR G2) to serve as the host router. The Cisco ISM-SRE is supported on the following routers:
–Cisco 1900 Series, 2900 Series, and 3900 Series ISRs
•Ensure that the host router is running Cisco IOS Release 15.0(1)M or a later release. To see which release your router is currently running, examine output from the show version command.
Note When minimum release requirements are met, you can change images on either the router or the internal service module without affecting performance.
Internal Service Module
•Install the ISM-SRE in the internal service module (ISM) slot of the Cisco 1900 Series, 2900 Series, or 3900 Series router. See the following:
–Cisco 1900 Series Hardware Installation Guide
–Cisco 2900 Series and 3900 Series Hardware Installation Guide
–Cisco Network Modules and Interface Cards Regulatory Compliance and Safety Information
•All ISM-SRE models ship from the factory with the hardware preinstalled as listed in Table 1.

Restrictions for the Cisco ISM-SRE
•Only one ISM-SRE can be installed in a single router chassis.
•Cisco 1900 Series routers do not support the ISM-SRE if an internal wireless module is installed. Because these modules are installed in the same location, Cisco 1900 Series routers can support either the internal wireless card or the ISM-SRE but not both at the same time.
Information About the Cisco ISM-SRE
To configure and manage the ISM-SRE, you should understand the following concept:
•ISM Network Interfaces
•Power Efficiency Management
ISM Network Interfaces
The ISM communicates with the host router through two internal Gigabit Ethernet (GE) interfaces (see Figure 1). One Gigabit Ethernet interface connects to the router Peripheral Component Interconnect Express (PCIe) back plane and is configured and managed using the Cisco IOS CLI; the other GE interface connects to the Multi-Gigabit Fabric (MGF) which is configured using the Cisco IOS CLI and managed by the application installed on the module.

Service-Module Interface
The service-module interface is used to access the service module console for configuration. Visible only to the Cisco IOS software on the router, the service-module interface is an internal Gigabit Ethernet interface between the router and the ISM-SRE. The service-module interface connects to the router's PCIe backplane, and all configuration and management of the service-module interface is performed from the Cisco IOS CLI.
MGF Interface
The Multi-Gigabit Fabric (MGF) interface enables the ISM-SRE to communicate with one or more service modules 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 the ISM and a service module. Configuration of the MGF interface is performed from the Cisco IOS CLI. The Cisco-authorized application running on the ISM-SRE manages the connections.
For information about configuring a HIMI connection, see the Cisco High-Speed Intrachassis Module Interconnect (HIMI) Configuration Guide.
For information about managing the HIMI-backplane interface, see the documentation for your Cisco-authorized application running on the ISM-SRE.
Power Efficiency Management
The power efficiency management feature is used to manage power that is supplied to the ISM-SRE on the Cisco 1900 Series, 2900 Series, and 3900 Series ISRs. The power efficiency management feature on these routers can be configured to power down unused modules and disable unused clocks to the modules and peripherals to reduce power consumption. The energywise levels for power efficiency management may differ for each type of module. For information on configuring power efficiency features, see the Cisco 3900 Series, 2900 Series, and 1900 Series Integrated Services Routers Software Configuration Guide.
How to Configure the Cisco ISM-SRE
This section describes how to configure basic network parameters for the internal service module using the Cisco IOS CLI. For additional configuration instructions, see the Cisco Services Ready Engine Configuration Guide or online help included with the Cisco-authorized application installed on the module.
This section contains the following tasks:
•Configuring the ISM Interface on the Router
•Configuring the MGF Interface on the Module
•Opening and Closing a Session
•Shutting Down and Starting Up the Cisco ISM-SRE
•Verifying the System Status
Note•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.
Configuring the ISM Interface on the Router
Your first configuration task is to set up the internal interface between the ISM and the host router, which enables you to access the internal service module to install and configure Cisco-authorized applications.

What to Do Next
•If you ordered the ISM-SRE with a Cisco-authorized application already installed on the module, see the online documentation for that application.
•If you need to install a Cisco-authorized application on the ISM, see the Cisco Services Ready Engine Configuration Guide.
Opening and Closing a Session
You can now open and close a session on the internal service module.
Note•Before you install your application software, opening a session brings up the bootloader. After you install the software, opening a session brings up the application.
•You can conduct only one session at a time.

Shutting Down and Starting Up the Cisco ISM-SRE
To shut down or start up the internal service module, select from the common router commands listed in Table 2.
Note The tables in these sections list only the most common router commands.
•To view a complete list of available commands, type ? at the prompt
(Example: Router(config-if)# ?).
•To view a complete list of command keyword options, type ? at the end of the command
(Example: Router# service-module ism?).
Note•Some shutdown commands can potentially disrupt service. If the command output for such a command displays a confirmation prompt, confirm by pressing Enter or cancel by typing n and pressing Enter. You can prevent the prompt from displaying by using the no-confirm keyword.
•Some commands shut the module or application down and then immediately restart it.
