Summary:A network flow information collection method and apparatus. A switching device receives a data packet, and collects network flow information of the data packet according to all flow entries when the data packet passes from an ingress port to an egress port in the switching device. All flow entries when a same network flow data packet passes from the ingress port to the egress port in the switching device are the same, and all flow entries when different network flow data packets pass from the ingress port to the egress port in the switching device are different. That is, all the flow entries passed from the ingress port to the egress port can uniquely identify one network flow. Therefore, each piece of the network flow information forwarded by the switching device can be accurately collected, improving accuracy of collecting network flow information by the switching device.
