set

Use the set boot loader command to set or display environment variables, which can be used to control
the boot loader or any other software running on the switch.
Note Under normal circumstances, it is not necessary to alter the setting of the environment variables.
Syntax Description variable value
OL-9645-10
set variable value
Use one of these keywords for variable and value:
MANUAL_BOO—Determines whether the switch automatically or manually
boots.
Valid values are 1, yes, 0, and no. If it is set to no or 0, the boot loader attempts to
automatically boot the system. If it is set to anything else, you must manually boot
the switch from the boot loader mode.
BOOT filesystem:/file-url—A semicolon-separated list of executable files to try to
load and execute when automatically booting.
If the BOOT environment variable is not set, the system attempts to load and execute
the first executable image it can find by using a recursive, depth-first search through
the flash: file system. If the BOOT variable is set but the specified images cannot be
loaded, the system attempts to boot the first bootable file that it can find in the flash
file system.
ENABLE_BREAK—Determines whether the automatic boot process can be
interrupted by using the Break key on the console.
Valid values are 1, yes, on, 0, no, and off. If it is set to 1, yes, or on, you can interrupt
the automatic boot process by pressing the Break key on the console after the flash
file system has initialized.
HELPER filesystem:/file-url—A semicolon-separated list of loadable files to
dynamically load during the boot loader initialization. Helper files extend or patch
the functionality of the boot loader.
PS1 prompt—A string that is used as the command-line prompt in boot loader mode.
CONFIG_FILE flash:/file-url—The filename that the software uses to read and
write a nonvolatile copy of the system configuration.
