By default, the device first attempts to boot from the image stored in its primary flash, then its secondary flash, and then from a TFTP server.
Privileged EXEC mode
Global configuration mode
You can use boot commands to immediately initiate software boots from a software image stored in the primary or secondary flash on an ICX device.
It is very important that you verify a successful transfer of the boot code before you reset the system. If the boot code is not transferred successfully but you try to reset the system, the system will not have the boot code with which to successfully boot.
You can modify the default booting sequence in the global configuration mode using the boot system command.
Execute the
write memory command to save the boot preferences to the startup configuration. If you are executing
the
boot system flash command from the Privileged EXEC mode, you can use the
yes option to save the boot preference to the startup configuration. Executing the
write memory command is not required in this case.
You can use the
show boot-preference command to view the boot sequence preference.
The
no form of the command resets the boot preference to the default.
