Syntax Description
Defaults The switch attempts to automatically boot the system by using information in the BOOT environment
variable. If this variable is not set, the switch attempts to load and execute the first executable image it
can by performing a recursive, depth-first search throughout the flash file system. In a depth-first search
of a directory, each encountered subdirectory is completely searched before continuing the search in the
original directory.
Command Modes Global configuration
Command History
Usage Guidelines Filenames and directory names are case sensitive.
If you are using the archive download-sw privileged EXEC command to maintain system images, you
never need to use the boot system command. The boot system command is automatically manipulated
to load the downloaded image.
This command changes the setting of the BOOT environment variable. For more information, see
Appendix A, “Catalyst 3560 Switch Boot Loader Commands.”
