Dear all, I install Layer 1 Flow Rules (namely: Port 1 ->Port 2, Port 2 -> Port 1) from Open Flow controller (as well as through ovs-ofctl): ovs-ofctl add-flow br0 in_port=1,idle_timeout=0,actions=output:2 I use 1000 test L4 UDP flows (with various dst.ports) to test the Switch with 1000 of packets in each 64 bytes size and ~0.2 Mpps rate
1. When I put test traffic into incoming port I see that it installs 1000 flows into its datapath with L4 granularity: in_port(2),eth(src=00:9c:02:ad:4e:1e,dst=00:9c:02:ad:4e:22),eth_type(0x0800),ipv4(src=10.0.0.1,dst=10.0.0.2,proto=17,tos=0,ttl=64,frag=no),udp(src=33864,dst=10864), packets:350, bytes:21000, used:-0.004s, actions:1,3 Is it correct behavior of OVS's internal logic? Shiould datapath install L1 flows or L4 flows in such case? I use ovs_version: "2.0.0" Besides this, I see the packet loss (about 3%) in OVS out of 1.000.000 packets arrived to its incoming port: sudo ovs-appctl bridge/dump-flows br0: duration=3908s, priority=32768, n_packets=997160, n_bytes=59829600, in_port=1,actions=output:2 duration=3908s, priority=32768, n_packets=0, n_bytes=0, in_port=2,actions=output:1 table_id=254, duration=7623s, priority=0, n_packets=0, n_bytes=0, priority=0,reg0=0x3,actions=drop table_id=254, duration=7623s, priority=0, n_packets=0, n_bytes=0, priority=0,reg0=0x1,actions=controller(reason=no_match) table_id=254, duration=7623s, priority=0, n_packets=0, n_bytes=0, priority=0,reg0=0x2,actions=drop 2. In ovs-dpctl utility there is the possibility to install flows directly in datapath. But when try following command it returns an error: sudo ovs-dpctl add-flow system in_port=1,idle_timeout=0,actions=output:2 ovs-dpctl: parsing flow key (Invalid argument) What is the correct syntax should be for such command? (I couldn't find IT neither in man page nor in examples) -- Best regards, Anton Matsiuk
