I did a small experiment with ONOS 3.0.5, OVS 2.0.2(OF 1.0), mininet 2.3.0d5
I found when making flow rule about L4 port, hitting flow table doesn't work properly. For example, about UDP flow, ip_src=10.0.0.3, ip_dst=10.0.0.2, udp_dst=50000 1) cookie=0x4c0000ef7faa8a, duration=332.717s, table=0, n_packets=8974, n_bytes=557090858, idle_age=153, priority=65050,ip,nw_dst=10.0.0.2 actions=output:4 2) cookie=0x4c0000951b3b33, duration=332.636s, table=0, n_packets=10, n_bytes=460,idle_age=168,priority=65111,udp,nw_src=10.0.0.3,nw_dst=10.0.0.2, tp_dst=50000 actions=output:3 Although the flow rule 2 have higher priority and more match field, the flow rule 2 was hit. When doing trouble shooting, I found the UDP datagram size affect the result. For 63kBytes datagram, the flow rule 1 is hit. However for 1500Bytes datagram, the flow rule 2 is hit. I think the datagram size degrade the match of OVS but I don't know exactly Could you give me a little hint?
