Hi all,


I am in the process of upgrading the rommon (bootstrap) of a Cisco 2621 router, the only method i've reached is to go to the rommon mode and do the following:


> rommon 4 > IP_ADDRESS=<ip_address_for_the_local_router>

> rommon 5 > IP_SUBNET_MASK=<subnet_mask>

> rommon 6 > DEFAULT_GATEWAY=<gateway>

> rommon 7 > TFTP_SERVER=<tftp_server_ip>

> rommon 8 > TFTP_FILE= c2600-i-mz.123-22.bin

> rommon 9 > tftpdnld -u


The problem is that when i did everything i was astonished that my router doesn't support the "-u" key, while other routers does.


Has any one faced this problem, or know a solution? I need to upgrade the rommon in order to support new features (like "no service password-recovery").


Thanks in advance,

Mohammed Mahmoud.

Mohammed,


There are only to options with "tftpdnld" command " -h, -r".


h is used for rommon help and r is used for loading the image directly to DRAM not in the flash. On which platform did u see "-u" option and what is the use ?

Hi Amit,


In the following document you can find the usage of the -u option:

What i've reached is that for some platforms i've to order the ROM as a hardware, and in other situations i can upgrade the rommon, can you confirm these results.


thanks in advance,

Mohammed Mahmoud.
