This object reports the current OSPF neighbor state machine position for the router at the other end of the sham link, following the standard OSPF adjacency states from down through init, twoWay, and on toward full. It matters because a sham link stuck partway through this progression, say stuck at twoWay rather than reaching full, points to a specific stage of adjacency formation that is failing, a very different problem than a link stuck at down where Hellos are not even being exchanged. An admin seeing this stall at exchangeStart would suspect a database description packet issue rather than a basic Hello or reachability problem.
