•
boot or b—Boot an image. The boot command with no arguments will boot the first image in
boot flash. You can include an argument, filename, to specify a file to be booted over the network
using the Trivial File Transfer Protocol (TFTP). The local device (see the description of b device
following) can be specified by typing the device specifier (devid). If the specified device name is
not recognized by the ROM monitor, the system will attempt to boot the image (imagename)
from a network TFTP server. Do not insert a space between devid and imagename. Options to the
boot command are -x, load image but do not execute, and -v, verbose. The form of the boot
command follows:
boot [-xv] [devid][imagename]
b—Boots the default system software from ROM
b filename [host]—Boots using a network TFTP server. When a host is specified, either by name
or IP address, the boot command will boot from that source.
b flash:—Boots the first file in Flash memory
b device:—Boots the first file found in the Flash device. The Flash device specified can be either
flash:, to boot the Cisco Internetwork Operating System (Cisco IOS), or bootflash:, to boot the
boot image in Flash.
b device:name—An extension of the above command, allows you to specify a particular filename
in the flash bank.
