I'd like to see Orion have an option to discover by a specific device interface type. We use loopback addresses in all our router devices as our managment interface because it never goes away as opposed to other interfaces that might be disconnected on purpose. The problem with current discovery is that it discovers based on the interface on a device that answers up first in the discover IP range. This causes multiple appearances of the same device in the database. We have had to stop using discovery for this very reason. Since loopback is a specific interface type it doesn't seem like this would be more than another discovery criteria selection. Unless of course there is already a way to do this that I'm missing.
I have captured this as an enhancement as I am not aware of any way to specify an specific interface.
