Actually I overlooked that (whoops!) so thanks for pointing it out. It's half working, however I had to use Full Name rather than Description to get it to work for some reason.
Only issue is it's showing all ports with that description across all devices and not just the node in question. I thought perhaps doing an Interface.NodeID = Node.NodeID would do the trick but apparently not. Nor will it let me do ${NodeID}. Any suggestions?
