Solved: Backup Router Config Using Console Port

dlitteer · ‎07-16-2007

How do I load the configuration from the production router to a backup router. The backup router is connected using only a console cable to a laptop. Since TFTP server uses IP and the ethernet port on the backup router is not connected, is my only resort to manually enter config line by line?

There are alternatives that are better than having to enter the config line by line. The easiest alternative is to log in to the primary router, do show running-config, use cut and paste to put the content of the config into a text file on the laptop, then log in to the backup, go into config mode, and paste the content of the config into the backup router, and then remember to do copy running-config startup-config to save the config on the backup.

That should work ok for you.

Thanks Rick. That worked fine. I tried that before I posted, but it would have helped if I was in configuration mode. One more question - this router has a spare 1port DSU/CSU T1 WIC that I want to remove. The configuration has it as serial 0/1. When I tried to enter "no interface serial 0/1" I received the message "removal of serial interfaces is not permitted" Can I just power down and remove this card?

Thanks. Dan

Hi Dan,

You can't and you don't have to do "no" for any physical interface, you can simply power off the router and remove the card.

I agree with Mohammed that all you need to do is to power down the router and then remove the WIC. All references to the interface in the config will be removed when the router boots and the WIC has been removed.

It worked fine. Thank you. This forum has been a very valuable resource and I look forward to the day when I can start providing help at some point rather than constantly receiving.

Thanks again.

Console allows you to use XMODEM. It is very slow, and IOS would take about an hour to load, but it is still very usable, and speed would not matter in your case.

Get configuration from production router, wither over TFTP or otherwise. Also you can connect to it through console, and do a copy "startup-config xmodem:" (Don't forget to start XMODEM in your console, by selecting XMODEM RECEIVE option)

Then connect to backup router with console, and do a "copy xmodem: startup-config".

(Don't forget to start XMODEM in your console, by selecting XMODEM SEND option, and selecting the configuration file you want to send)
