This object is used by the networking entity to select a route based on administrative weight of possible routes. Administrative weights of links and nodes contained in a path are aggregated and compared against this object. The networking entity prefers a path whose aggregate administrative weight is lesser than the value of this object. Setting this parameter to 0 indicates to the switch that only the best available route should be chosen. If this object is set to a value of 0xFFFFFFFF(4294967295), then switch ignore this metric in making routing decisions. This parameter is not allowed to be set on a slave endpoint. (i.e. if 'cwaChanRoutingMastership' is set to 'false').
