Appendix B Catalyst 2950 and 2955 Switch Boot Loader Commands

boot

Use the boot boot loader command to load and boot an executable image and to enter the command-line

interface.

boot [-post] filesystem:/file-url ...

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 Boot loader

Command History

Usage Guidelines When you enter the boot command without any arguments, the switch attempts to automatically boot

the system by using the information in the BOOT environment variable, if any. If you supply an image

name for the file-url variable, the boot command attempts to boot the specified image.

When you set boot loader boot command options, they are executed immediately and apply only to the

current boot loader session. These settings are not saved for the next boot operation.

Filenames and directory names are case sensitive.

Examples This example shows how to boot the switch using the new-image.bin image:

switch: boot flash:/new-images/new-image.bin

After entering this command, you are prompted to start the setup program.

Related Commands
