Rolling back to an existing configuration, easiest steps

Unanswered Question
Dec 4th, 2008

Im making changes to my existing IOS configuration on my voice routers. I have two methods I can rollback to the saved configuration.

If the configurations do not work, I can simply do a "reload" and it will load the startup-config which is the orginal state the router was in before adjustments.


I can go into my configuation, and do "no" statements on the features I enabled or changed, and then copy and paste the original configuration back in.

IS there an easier method? I tried to use "Copy startup-config to running-config" and that did not remove the features I put in the config.


Dial-Peer voice 800 voip

Destination ip

My original configuration does not have this. The only way I see to get rid of it is to go and do "No dial-peer voice 800" etc.

I have probably 30 statements and 50 routers to do. If I need to rollback, I need a quick way.

Any suggestions or shortcuts?


I have this problem too.

I just found that... so funny. Yeah, I tried it on my 12.4. Works good. I will have to try on 12.3 and see how it works.

Just to add 12.3 does not support this feature. 12.3T and later do.

Good luck :-) Have fun!
