can you save the running config to a file, make changes to running config, then easily perform a rollback by "copy FILENAME run" or do you have to "copy FILENAME start" followed by reload? |

running-config and startup-config are different files. You can save the current running config as: R1#copy run flash:fileneme1 then restore by: R1#copy flash:filename1 run same for startup. R1#copy start flash:filename2 if you do a R1#copy run start this will sync the two file Edit: you can save to tftp, ftp, scp, usb, ect... Do the following to see the options for your IOS R1# copy run ? A reload may not be necessary, but it's hard to say without knowing the IOS version. |
If you do a "copy flash:\filename run" it will actually try to merge the files. I did that once I heard that doing the merge can cause "issues".  I've been meaning to try IOS Configuration Replace & Rollback in my lab environment. When I am making changes in my production enviroments, currently I keep a copy of what I am removing and the commands to remove what I am adding in a Notepad++ window. |

Quoted: can you save the running config to a file, make changes to running config, then easily perform a rollback by "copy FILENAME run" or do you have to "copy FILENAME start" followed by reload? You may need to reload depending on the configuration. Some commands won't be "unconfigured" by loading another config "hot." Quoted: Yup, its easy, just replace the Cisco with a Juniper. Hey! We'll have none of that! |
