rommon when boot up

I work for an ISP and we recently recieved an upgrade for our 2600. I was going to load it on a spare 2600 and then swap them out. I was in middle of tftp the image and it kept timing out. I shutdown the router and was going to move it somewhere else on the network with less traffic, now the router only boots in rommon and i cant figure how to tftp the new image to it. any suggestions?? I dont want to do to the one thats in use cause in keep having low memory problems, but i tried and it failed, now i fear if i reboot it, it will have the same problem. this going to be true?

thank in advance

Re: rommon when boot up


So you are on Romon. First attach a PC with TFTP server to the ethernet port on the 2600. Then on the romon configuration put the following:

rommon 16 > IP_ADDRESS=

rommon 17 > IP_SUBNET_MASK=

rommon 18 > DEFAULT_GATEWAY=

rommon 19 > TFTP_SERVER=

rommon 20 > TFTP_FILE=c2600-is-mz.113-2.0.3.Q

Of course, put the IP values that you want(make sure they are consistent). Then put

rommon 21 > tftpdnld

It will ask you to boot. When it boots it will try to grab the IOS image of the TFTP server. Make sure you write the proper IOS image name on TFTP_FILE parameter. Also check if you miss to write the .bin extension. If you receive an error regarding file not found on the TFTP log it may be that the file is not written correctly on the router variable or the path of the TFTP does not contain the image that you are looking for.

C ya!

Re: rommon when boot up

i tried that and it didnt work, i am going to try it again. my main problem though is the router that is in line right now has no flash cause it had to be erased to attempt the tftp. so if it reboots it will be stuck in rommon too and i dont want that. i am sure there is a way to restore my flash mem isnt there? the router has been having memory problems and thowing up errors so we were ugrading to the latest ios to try and fix it.
