    So, I have a quick question for an IOS command.

    When would you use "copy start run?"

    If "copy run start" writes into NVRAM for next-boot, what does the first one do?

    Thanks.

    Running config is your live config, where as startup config is a saved file, so if you change something in your running config, ie live on the network then if you don't write it to startup, if you restarted the router that change would no longer exist. After and changes you should verify the results as what you want and write it to startup.

    Then to answer your question, if you were making changes in your running config and something went badly wrong, but you weren't sure what or how to fix it then a fix would be to run startup config again to recover your last known good configuration, I assume that's what you are asking at least? A little like a restore point in Windows etc, quick way to get back to a known working state.
