rtgDpnTputMetricRangeBoundary
rtg Dpn Tput Metric Range Boundary
This attribute specifies the total path throughput metric below which the variance value specified for throughput COS and a low metric range is used, and at or above which the variance value specified for throughput COS and a high metric range is used. This attribute defaults to 0, so that the variance value specified for throughput COS and a high metric range is used for all delay paths. If this attribute is set to 2147483647, the variance value specified for throughput COS and a low metric range is used for all throughput paths.
