This OID is a running total of all inbound packets received on this 10 Gbps Ethernet (10GbE) interface since its statistics were last cleared. Tracking total packet count alongside the octet count lets an admin derive the average inbound packet size on this link, which helps distinguish a bulk-transfer workload from one dominated by many small packets. For example, if this counter on a 10GbE client port carrying a customer's Ethernet handoff grows quickly while the inbound octet counter grows only modestly, the traffic mix is dominated by small packets, worth knowing when sizing for packet-processing capacity rather than raw bandwidth.
