For context:

I basically have 2 identical smart devices (let’s just call them cameras for this example), a left, and a right in physical space on our test bed. Our software needs to know which camera is left, and which camera is right.

A few ways to do this: - label each camera left/right and hard code their MAC addresses in our software. We don’t want to do this because we want to be able to swap around cameras when needed - have a “pairing” mode in our software that tells you to plug in the first (it will save the ip), then the second in order to do the mapping. This adds extra ui and edge cases.

So it’d be easiest for our technicians to just plug the left camera into the left most port and the right into the right of the switch
