If a node has more than one interface. You should be able to choose the interface for each DCI. Maybe if nothing is choosen, NetXMS uses the interface of the Primary IP address. At the moment we need to create a second node for that and use proxy node. But that's not very elegant.

That could be used for baseboard management interfaces and also for nodes with interfaces in different vLANs.

Or how far are the plans for the object class "Management Board", as Alex said in this post?:
