boot system
Use the boot system global configuration command to specify the software image to load during the next
power on cycle. Use the no form of this command to return to the default setting.
boot system filesystem:/file-url ...
no boot system
This command is available only on Catalyst 2950 Long-Reach Ethernet (LRE) switches.
Syntax Description
Defaults The switch attempts to automatically power on 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 the
switch continues to 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
do not ever 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 B, “Catalyst 2950 and 2955 Switch Boot Loader Commands.”
