I haven't worked with the 585, but the answer probably depends on whether or not the ports have unique mac addresses (i.e is it a hub or a switch?)
Since BBSM tracks mac addresses at L2 and router hops for L3 conns, I would think that it would be possible if you could nail down a mac for a port. My guess however is that the 585 is acting as a hub and therefore probably isn't possible.
