This read-create enumerated value sets the drop precedence for this path using a traffic-light scheme of red, yellow, or green, or none, indicating how aggressively packets on this tunnel should be dropped under congestion relative to other traffic. An administrator wanting a best-effort tunnel to be the first candidate for discard during congestion would set csMplsPathDropPrecedence to red, while a premium tunnel would be set to green to protect it from early discard.
