In this post, we’ll go over the steps needed to install a new WAAS module for a ISR router straight out of the box!

The ISR router (2600, 2800, 2900’s) is kind of like the swiss army knife of the branch office. You can slap in a UCS-E blade or a WLC controller for example. In this post, we’ll go over a brand new installation for a WAAS module.

First, the WAAS doesn’t come with any images installed (weird I know, most of Cisco’s gear comes with SOMETHING). So let’s go to the Cisco site to pull down the image. Thing is there are so many different versions, which to choose?


This list could get pretty long. For my case, I’m not installing this as a VM so let’s skip the OVA files and down to the SRE files.

The SM/SRE Install Zip File for NPE  Login & Valid Contract Required

This is the one I want.  When you download and extract the zip you get theses files. Let’s put these files in a FTP server for our WAAS to download.


Next, let’s go to our ISR router and go into the SM x/0 interface. Similiar to other modules, we need to give this service module (SM) IP information. The final config should look something like this…

interface SM1/0
 ip address
 ip wccp redirect exclude in
 service-module ip address
 service-module ip default-gateway

Now let’s just make sure the ISR and SM x/0 can ping the FTP server. Do a source ping to source it from the SM x/0 interface. once we know that works, let’s download that image!

ISR_ROUTER#service-module sm1/0 install url ftp://william@password@

We want to specify here the username (william), password (password), IP of the FTP server ( and the name of the .bin file to start this process off. Note this process takes a good 10-15 minutes or more depending on your bandwidth speeds since it will slowly start pulling all the files in zip above (the .sre, the .installer, .key, etc).

Occasionally you can check your FTP server connections to verify that its pulling down the files and you can also on the ISR router see the status of the install by typing #service-module sm1/0 status and see the status of the install…

#service-module sm1/0 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 is in fail open
Service Module status is not available

Module resource information:
  CPU Frequency: 1864 MHz
  Memory Size: 2530 MB
  Disk 0 Size: 500107 MB
  Disk 1 Size: 500107 MB
  Disk 2 Size: 2055 MB

Install of ftp://*****:*****@ in progress
Install status : File waas-accelerator-5.3.5c.9-k9.bin.install.sre requested

Localstore Info – (0 apps)
  Retrieving localstore information

Once its complete, you’ll see the lines “No install” or something to that effect at the bottom of the status command.

here you need to wait about 5-10 minutes for you to telnet into the WAAS module and start configuring the Central manager settings. Or you can console into it from the ISR itself by…

#service-module sm1/0 session

Default credential are username: admin password: default

All we need to do next is change the hostname of the WAAS device and point it to your central manager  to pull down sessions by…

WAAS(config)#central-manager addr
(config)#cms enable

Done! When you exit in and telnet/console back in policies should start to get applied to your WAAS and you should see it appear in your Central Manager.
