Use the boot system global configuration command on the switch stack or on a standalone switch to
specify the Cisco IOS image to load during the next boot cycle. Use the no form of this command to
return to the default setting.
boot system {filesystem:/file-url ...| switch {number | all}}
no boot system
no boot system switch {number | all}
filesystem:
/file-url
switch
number
all
The switch attempts to automatically boot up 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.

Filenames and directory names are case sensitive.
If you enter the boot system filesystem:/file-url command on the stack master, the specified software
image is loaded only on the stack master during the next boot cycle.
On the stack master, use the boot system switch number command to specify that the software image is
loaded on the specified stack member during the next boot cycle. Use the boot system switch all
command to specify that the software image is loaded on all the stack members during the next boot
cycle.
