An engineer applies a Flexible NetFlow monitor to interface GigabitEthernet0/1 in the input direction to troubleshoot excessive WAN utilization. The collector receives flows for traffic entering the router but reports show almost no data for traffic destined to hosts behind that interface, even though users confirm heavy downloads are occurring. The engineer wants the same monitor to also account for traffic leaving Gi0/1 toward the LAN. What is the correct action to capture this traffic?
