This read-only value reports the port's current ingress utilization as a percentage, using a scale extending up to 1000 (i.e., tenths of a percent) rather than a simple 0-100 range, allowing finer resolution than ingrRcvUtilization's plain gauge. An administrator uses this finer-grained figure to detect ingress load trends with more precision, especially near saturation. For example, a reading of 985 indicates the port is running at 98.5 percent of its ingress capacity.
