Catalyst 2350 Switch Cisco IOS Commands
boot system
Use the boot system global configuration command to specify the Cisco IOS image to load during the
next boot cycle. Use the no form of this command to return to the default setting.
Syntax Description
filesystem:
/file-url
Defaults
The switch attempts to automatically boot up 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.

Usage Guidelines
Filenames and directory names are case sensitive.
If you enter the boot system filesystem:/file-url command the specified software image is loaded during
the next boot cycle.
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 2350 Switch Boot Loader Commands."
