As I said, you can try disabling LLDP and see if we will populate the links via the STP Bridge MIBs.... is spanning tree enabled on the Transition switches or in your environment?
This will work without LLDP, however I am not sure how to force it to make it use another method, or if they work simultaneously. try using MIBtools to pull the bridge MIBs or some flexviews and see if you can manually line up some MAC addresses. if you can, maybe it is time to get GTAC involved to figure out why OneView is not using the STP information.
