how does one "print" the startup config or running config.
also what is the best way to import config you have stored as a text file?
Starting conf: #show startup-config
Running conf: #show running-config
If you have it already on the box, it's as easy as: #copy (desired-running-config) running-config
copy new-config running-config
won't actually replace the running-config - it will actually merge the two configs. If you want to completely replace a running configuration, you must copy the new config to startup-config and then reload.
I highly recommend you to create a TFTP server, especially if you are experimenting a lot. You can copy much easier from the router to the server and the other way around. Once you have the TFTP server, you can just:
router#copy tftp://new-config running-config
