This object is a 64-bit high-capacity counter that tracks the total number of unicast (non-multicast, non-broadcast) packets received on a 10-gigabit Ethernet interface since last counter reset. It provides long-term traffic volume monitoring without 32-bit counter overflow. An operator would use this metric to measure sustained data traffic volumes, capacity planning, and to detect unusual traffic patterns or performance anomalies on 10-gigabit links.
