Using the TFTP Download Command

The steps described in this section should be performed while in ROM monitor

mode.

Step 1 Use the appropriate commands to enter all the required variables and any optional

variables described earlier in this section.

Step 2 Enter the tftpdnld command as follows:

rommon 1 > tftpdnld [ -r ]

Note The -r variable is optional. Entering this variable downloads and boots

the new software but does not save the software to Flash. You can then

use the image that is in Flash the next time you enter the reload

command in the Cisco IOS software CLI.

You will see output similar to the following:

IP_ADDRESS: 10.0.0.1

IP_SUBNET_MASK: 255.255.0.0

DEFAULT_GATEWAY: 1.3.0.1

TFTP_SERVER: 223.255.254.254

TFTP_FILE: c1700-bnr2sy-mz.070298

Invoke this command for disaster recovery only.

WARNING: all existing data in all partitions on flash will be lost!

Do you wish to continue? y/n: [n]:

Step 3 If you are sure that you want to continue, enter y in response to the question in the

output:

Do you wish to continue? y/n: [n]:y

The router will begin to download the new file.

Pressing Ctrl-C or Break stops the transfer before the Flash memory is erased.
