Managing the Firewall Services Module Boot Partitions Chapter 2 Configuring the Switch for the Firewall Services Module Note The switch supports autostate messaging only if you install a single FWSM in the chassis. Autostate messaging is disabled by default. To enable autostate messaging in Cisco IOS software, enter the following command: Router(config)# firewall autostate Managing the Firewall Services Module Boot Partitions This section describes how to reset the FWSM from the switch, and how to manage the boot partitions on the Flash memory card. This section includes the following topics: • Flash Memory Overview, page 2-10 • Setting the Default Boot Partition, page 2-10 • Resetting the FWSM or Booting from a Specific Partition, page 2-11 Flash Memory Overview The FWSM has a 128-MB Flash memory card that stores the operating system, configurations, and other data. The Flash memory includes six partitions, called cf:n in Cisco IOS software commands: • Maintenance partition (cf:1)-Contains the maintenance software. Use the maintenance software to upgrade or install application images if you cannot boot into the application partition, to reset the application image password, or to display the crash dump information. • Network configuration partition (cf:2)-Contains the network configuration of the maintenance software. The maintenance software requires IP settings so that the FWSM can reach the TFTP server to download application software images. • Crash dump partition (cf:3)-Stores the crash dump information. • Application partitions (cf:4 and cf:5)-Stores the application software image, system configuration, and ASDM. By default, Cisco installs the images on cf:4. You can use cf:5 as a test partition. For example, if you want to upgrade your software, you can install the new software on cf:5, but maintain the old software as a backup in case you have problems. Each partition includes its own startup configuration. • Security context partition (cf:6)-64 MB are dedicated to this partition, which stores security context configurations (if desired) and RSA keys in a navigable file system. Other partitions do not have file systems that allow you to perform common tasks such as listing files. This partition is called disk when using the copy command. Setting the Default Boot Partition By default, the FWSM boots from the cf:4 application partition. However, you can choose to boot from the cf:5 application partition or into the cf:1 maintenance partition. Each application partition has its own startup configuration. To change the default boot partition, enter the following command: Router(config)# boot device module mod_num cf:n 2-10 Catalyst 6500 Series Switch and Cisco 7600 Series Router Firewall Services Module Configuration Guide using ASDM OL-20748-01
