How to download and install FWSM software


What is FWSM?

The Firewall Services Module (FWSM) is a high-performance stateful-inspection firewall that integrates into the Cisco 6500 switch and 7600 router chassis. The FWSM monitors traffic flows using application inspection engines to provide a strong level of network security. The FWSM defines the security parameter and enables the enforcement of security policies through authentication, access control lists, and protocol inspection. The FWSM is a key component to anyone deploying network security.


Refer to Cisco Downloads in order to download the latest FWSM software.

Complete these steps in order to upgrade the FWSM software image:

  1. Make the new software image available on a TFTP server, or make the MSFC a TFTP server with this command:

    tftp-server bootflash:image name

  2. If the MSFC is the TFTP server, make sure you have a VLAN interface on the MSFC reachable from the module. For example:

    1. On the MSFC, enter these commands:

      router(config)#interface Vlan30
      router(config)#description to_fwsm_vlan_30
      router(config)#ip address
      router(config)#no ip redirects

    2. On the module, enter these command:

      nameif vlan30 inside security100
      ip address inside

    3. Enter this command rom the module in order to make sure that you can ping the MSFC:

      FWSM# ping

  3. From the module enter the copy tftp flash command:

    FWSM#copy tftp flash
    Address or name of remote host []?
    Source file name [cdisk]? c6svc-fwm-k9.1-1-0-207.bin

  4. Issue this command in order to reload the module:
