If I understood you correctly you have a network configuration in which you have multiple access points that are connected to a Wireless LAN Controller, and you'd like to see this relation between the AP's and WLC automatically mapped when these devices are scanned. Unfortunately, other than as you indicate, potential port connection information between these devices, no relation is scanned, and a relation would have to be
manually mapped.
I've added "the automatic mapping of asset relations between access points and Wireless LAN controllers" to our customer wishlist and moved your topic to the wishlist section of our forum in this context. At this moment in time we can't yet guarantee that this feature will be implemented though and cannot provide you with an estimated release date.
