Boot System - Cisco Catalyst 3120 Command Reference Manual

boot system

boot system
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.
Syntax Description
filesystem:
/file-url
switch
number
all
Defaults 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.

Usage Guidelines 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.
When you enter the boot system switch number or the boot system switch all command on the stack
master, the stack master checks if a software image is already on the stack member (except on the stack
master). If the software image does not exist on the stack member (for example, stack member 1), an
error message like this appears:
