Boot - Cisco Catalyst 3030 Command Reference Manual

boot

boot
Use the boot boot loader command to load and boot an executable image and to enter the command-line
interface.
Syntax Description
-post
-n
-p
filesystem:
/file-url
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

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.
