Indicates whether low congestion will be tolerated. This object and appnCosNodeRowMinCongestAllow together delineate a range of acceptable congestion states for a node. For the ordered pair (minimum congestion allowed, maximum congestion allowed), the values are interpreted as follows: - (0,0): only low congestion is acceptable - (0,1): either low or high congestion is acceptable - (1,1): only high congestion is acceptable. Note that the combination (1,0) is not defined, since it would identify a range whose lower bound was high congestion and whose upper bound was low congestion.
