boot
boot
To boot a router manually, use the boot command in ROM monitor mode.
Syntax Description
x
v
device:
imagename
filename
tftp-ip-address
tftp://server/path/filename Specifies the complete TFTP URL for the filename to be downloaded and run.
Defaults
If specified without any options, the boot command loads and executes the first file on the default memory
device. If a device is specified without a filename, the boot command loads and executes the first file on that
device. If a filename is specified without a TFTP server IP address, the boot command advertises for a TFTP
server using the IP broadcast address of 255.255.255.255 and uses the first TFTP server that responds.

(Optional) Loads the specified image into the router's memory but does not
execute it.
(Optional) Enables verbose mode to display debugging information as the
image is loaded and executed.
(Optional) Specifies that the router should boot an image on the specified
device. If not specified, the router boots from the default memory device.
(Optional) Specifies the filename for the image to be booted and loaded. If not
specified, the router boots the first file on the specified device.
Note
Specifies the path and filename for the image that the router should download
from a Trivial File Transfer Protocol (TFTP) server.
Note
(Optional) Specifies the IP address for the TFTP server from which the router
should download and boot the specified filename. If not specified, the router
sends a TFTP request to the IP broadcast address of 255.255.255.255 and uses
the first TFTP server that responds.
This URL should specify the fully-qualified server name (or IP address), full
path on the TFTP server, and filename to be downloaded.
Modification
This command was introduced on Cisco uBR7200 series routers.
When specifying both a device: and imagename, do not put any
spaces between the two arguments.
You must specify the full path for the desired file, as it exists on
the TFTP server.
