dump-aggregate command means you want to aggregate some field, right? For example suppose there are 4 flows, two of them have the same dst IP. Then, dump-aggregate dst_IP will return 2 flows. Instead, dump-flows is to show all the flows. So, my question was, does dump-aggregate work properly for all the fields?
