Introduction
Cisco Service Module-Services Ready Engine (Cisco SM-SRE) hosted by the Cisco ISR G2 have their own processors, storage, network interfaces, and memory that operate independently of the host router resources. This configuration helps to ensure maximum concurrent routing and application performance. Cisco SRE supports installing and uninstalling Cisco-authorized software, such as Cisco Unity Express, Cisco Application eXtension Platform (Cisco AXP), and Cisco IP Video Surveillance using Cisco IOS software commands and prevents unauthorized software and applications from running on Cisco SRE modules. Cisco SRE also supports a common uninstall process across all supported software. After the application software is installed, the SMs have their own startup and run-time configurations that are independent of the Cisco IOS configuration on the host router. The SMs do not have an external console port.
Restrictions for WAAS installed on SRE Service Module
The restrictions for WAAS on SRE are as follows:
Upgrade/Downgrade
You can do a software upgrade or downgrade only on an inactive system. You must plan upgrades or downgrades for times when you can take all applications that run on the host router out of service or offline.
Configuration
You can configure service module software only by using a console that connects to a router console port.
The Cisco IOS software installer script must be on the same server and in the same directory as the application package files.
SM-SRE WAAS image installation
Verify if the IOS software image installed on ISR-G2 is supported by WAAS SM-SRE module. The host router should be running Cisco IOS release 15.0(1)M1 or later. Follow these steps to Install WAAS on SRE:
- 1. Download WAAS SRE Image zip file from CCO.
- 2. Setup a new FTP Server /Use an existing FTP server to copy the image. This FTP Server should be reachable from the WAEs.
- 3. Extract the zip file to a FTP Server and ensure all the six files are present in the same folder.
The CCO zip file for SM-SRE initial installation includes 6 mandatory files required for the upgrade. They are:
* WAAS-4.2.1-K9.bin.srebootloader (Boot Loader)
* WAAS-4.2.1-K9.bin.install.sre.header (TCL file signature)
* WAAS-4.2.1-K9.bin.install.sre (TCL file)
* WAAS-4.2.1-K9.bin (WAAS package)
* WAAS-4.2.1-K9.key (WAAS application key)
* WAAS-4.2.1-K9.installer
These 6 files must be in the same directory for a successful installation.
- 4. Configure WAAS IP Address for the remote location from the router directly.
interface SM 1/0
ip address
service-module ip address
service-module ip default-gateway
- 5. Install WAAS Image on the SM SRE Module from router directly
ISR# service-module sm 1/0 install url ftp://<username>:<passwd>@<ftpserver>/<directory>/waas-accelerator-4.2.3.9-k9.bin
The whole procedure of installing software takes about 10-15 minutes and during this period, the status of the software upgrade can be viewed from the ISR router. It is not recommended to session into the module while software upgradation is in progress.
You may see following status messages while the upgradation process:
ISR# service-module sm 1/0 status
Service Module is Cisco SM1/0
Service Module supports session via TTY line 67
Service Module is trying to recover from error
Service Module heartbeat-reset is enabled
Service Module status is not available
Install of ftp://abc:abc@10.3.1.5/waas-accelerator-4.2.3.9-k9.bin in progress
Install status : File waas-accelerator-4.2.3.9-k9.bin.key requested
ISR#service-module sm 1/0 status
Service Module is Cisco SM1/0
Service Module supports session via TTY line 67
Service Module is in Steady state
Service Module heartbeat-reset is enabled
Getting status from the Service Module, please wait..

Basic Configuration for WAAS on SM
Once the image is installed, session to the module from the router:
ISR# service-module sm 1/0 session
After login configure the basic commands on the service module:
restore factory-default
device mode application-accelerator
!
hostname xyz
central-manager address a.b.c.d
!
interface GigabitEthernet 1/0
ip address w.x.y.z
!
primary-interface GigabitEthernet 1/0
ip default-gateway w.x.y.a
!
ip name-server
ip domain-name
ntp server
clock timezone
!
clear license Transport
license add Enterprise
!
cms enable
