This read-only value reports the port's current egress utilization as a percentage on the same fine-grained 0-1000 scale used by its ingress counterpart, giving tenths-of-a-percent resolution. An administrator watches this value to catch a port's egress load creeping toward saturation with more precision than a plain 0-100 gauge would allow. For instance, a value of 1000 indicates the port's egress side is fully saturated at 100.0 percent utilization.
