Problems copying startup config to running config on Nexus 1000v

This post has nothing to do with the design or functionality of the Nexus 1000v but more of a mistake I managed to make without really thinking. I always joked with clients about how my CCNA has expired 2 years ago and how my IOS skills have gone from mediocre to below average and as funny as I always thought that sounded, this is definitely a story to tell others in the future. Nonetheless, I hope anyone that might experience the mistake I made will find this post through the error message that gets printed out.

The short and skinny:

While configuring the VLANs on a Nexus 1000v, I would constantly run into an error message when typing copy start run which is short for copy startup-config running-config. I bet all you networking engineers out there are already laughing at me but for those who didn’t catch that, the command is incorrect because what I meant to type was really copy running-config startup-config. If you manage to make the same mistake as I did, you’ll see the following:

rsa keys already present, use force option to overwrite them

To fix this problem, type the proper command. :)
