Migrate IP address to other interface

I have a Cisco 2811 with fa 0/0 as my bearer, and a switch module for internal clients.

I have an issue with my fa 0/0 flapping, I want to move that ip configuration to fa 0/1

as this is a branch office I am reliant on the bearer port to give me coms so changing the IP addresses is difficult.

Has any one tried this with a TCL script?

Any other ideas would be appriciated.

You should not need TCL script for this.  Have an outage window, copy the commands that are under interface fa0/0 into a notepad. Delete the config on fa0/0 and paste the config from notepad to fa0/1. Test to make sure the connection is up and traffic is passing.

I'm accessing the the router via fa 0/0 as soon as I delete the IP address on the interface, I will lose remote access.

Remote access via f0/0 currently?

Haven't tried using a script, but you might update the startup config and schedule a reload.


Re: Migrate IP address to other interface

I'm think about just modifing the start up script but I'm worried I wont have a roll back option.

If I can TCL, then I can schedule a reload change the ip addresses, and if I lose coms to the box it will reload itself and be back to normal.
