In case you by mistake make some change that breaks your Arista home network, you can always go back to zero by following the generic 30 30 30 hard reset trick.

This is usually the last resort, and if you still have access to the Arista interface you can always login to try and revert the settings first (This of course assumes you wrote down the original value before changing it).
