The software upgrade procedure is the same for both vpn firewall modules. This chapter uses the

LST1FW3A1 module installed in an 12508 to describe how to upgrade software from the CLI, Web

interface, and BootWare menus.

Software types

The following software types are available:

 BootWare image—A .btw file that contains a basic segment and an extended segment. The

basic segment is the minimum code that bootstraps the system. The extended segment

enables hardware initialization and provides system management menus. You can use these

menus to load software and the startup configuration file or manage files when the firewall

module cannot start up correctly.

 System software image—A .bin file that contains software features. You can assign the

following attributes to a system software image:

 Main—The image is the primary image. The system always attempts to load the main

image at startup in preference to the backup image.

 Backup—The image is the backup image. It is used only if the primary image is corrupt or

not available.

 Secure—The image is the secure image. If both the main and backup system software

images are corrupt or not available, the device starts up with the secure system software

image. If no secure system software image is available, the firewall module displays a

failure prompt.

When you upgrade the system software, the BootWare is upgraded automatically. You do not need

to upgrade BootWare separately.

Configuration files

You can save settings you made to a configuration file so they can survive a reboot.

The firewall module supports .cfg and .xml configuration files. The .cfg configuration file saves

settings made at the CLI and in the Web interface. The .xml saves only settings made in the Web

interface.
