Appendix C Using the ROM Monitor

Using the tftpdnld Command

Note
The command tftpdnld is present in the Cisco 2600 series routers only.
The tftpdnld command downloads a Cisco IOS software image from a remote server into flash memory
using TFTP.
The syntax for specifying the variables is:
VARIABLE_NAME=value
After you specify the variables, you must reenter the tftpdnld command. For example:
rommon 1 > tftpdnld
rommon 2 > IP_ADDRESS=172.15.19.11
rommon 3 > IP_SUBNET_MASK=255.255.255.0
rommon 4 > DEFAULT_GATEWAY=172.15.19.1
rommon 5 > TFTP_SERVER=172.15.20.10
rommon 6 > TFTP_FILE=/tftpboot/c2600-i-mz
rommon 7 > TFTP_VERBOSE=1
rommon 8 > tftpdnld
Invoke this command for disaster recovery only.
WARNING: all existing data in flash will be lost!
