When you do this, what interface is getting assigned the IP address? Does the router use the first Ethernet/FastEthernet interface?

Thanks,

Jeff

Now THIS is handy to have! Thanks for the tip!

Jeff,

I may be wrong, and JC may correct me. But, I believe rommon builds it's own virtual interface, during the rommon session. When you leave the rommon session, you lose the configuration you made in it.

Yeah, it's the first LAN port (http://www.cisco.com/warp/public/471/76.html confirms this).

doing a "sync" (I think? check the rommon help) before the tftpdnld oughta make it remember the settings.

I've used this same procedure to recover from an error of my own creation on my home lab. I only had one FE interface so I assume that the ip address would be assigned to the 0 interface (ie ethernet0, fe0/0).

I believe this only works with an onboard fe interface. I had no luck on a 3640 that had nm interfaces in the past. Maybe I just got lucky with 2620xm. Way cooler than waiting on XModem. Like sledding on rocks to ice.

It's funny you say that David - I just tried it on a 3640 and found the TFTPDNLD command missing from RomMon - I'd definitely say this is for routers that have a on-board FE interface.

Did anyone catch my question/post about HSRP in the routing section? It's a little different since it applies to an ISP scenario. If I need to clarify the layout a little more for an answer I can do that.

When assigning ip address in rommom of cisco router to which ethernet port the ip address will get assigned(If i had two ethernet port on my router)

Hey JC, I experienced exactly this. I couldn't find the command. But when I did a reboot on the machine, something odd happened. It seemed to download the image file after reboot.

Thank yo very much. It did the work for me.

Hi Jeremy,

I had a notebook containing these ROMMON commands used for recovering the image, just in case I forgot them. Today, I found out that if you simply type "tftpdnld", nothing happens (natch) but you do get a response containing all of the commands you need before initiating the download.

Also, for people who need to do an XModem transfer, you can set a config register value to boot from ROM and also set a higher baud rate.

0x3922 - Boots into ROM (ignoring break) with a console baud rate of 115200bps

Hello Sir
I am new to your site I hope you will help me.
In my cisco 2611 lab router i had some issue so i erased flash & CHANGE CONSOLE SPEED TO 115200 & reboot the router. After that i changed my connection settings & try to connect router it showing the console is connected but it is not boot up in Rommon mode so i can’t type anything. I tried to all eight connection speed one by one to connect via console but the result is same. Rommon mode is not showed up.
waiting for reply
