Hi, I am experiencing a weird behaviour when I test my system with ping.
I installed flow/group tables so that an alternative path can be found in case of a link failure. In the test I am breaking the link between s2 and s5 (in mininet) and I am seing a really weird behaviour in s5: some packets disappear after arriving in this switch... What I don't understand is that I didn't put any rule to drop the packets. And actually ovs-appctl doesn't show me that any packets are dropped (but they are not being forwarded anywhere...): $ sudo ovs-appctl bridge/dump-flows s5 duration=360s, n_packets=11, n_bytes=1078, priority=1,ip,nw_dst=11.0.0.1,actions=group:1 duration=360s, n_packets=3, n_bytes=294, priority=2,ip,nw_dst=11.0.0.2,actions=group:2 duration=360s, n_packets=5, n_bytes=510, priority=9,ip,in_port=4,dl_vlan=1,nw_dst=11.0.0.1,actions=group:6 duration=360s, n_packets=0, n_bytes=0, priority=3,ip,in_port=1,dl_vlan=1,nw_dst=11.0.0.1,actions=group:3 duration=360s, n_packets=1, n_bytes=102, priority=7,ip,in_port=3,dl_vlan=1,nw_dst=11.0.0.1,actions=group:5 duration=360s, n_packets=9, n_bytes=910, priority=6,ip,in_port=2,dl_vlan=1,nw_dst=11.0.0.2,actions=group:4 duration=360s, n_packets=1, n_bytes=102, priority=5,ip,in_port=2,dl_vlan=1,nw_dst=11.0.0.1,actions=group:4 duration=360s, n_packets=2, n_bytes=204, priority=8,ip,in_port=3,dl_vlan=1,nw_dst=11.0.0.2,actions=group:5 duration=360s, n_packets=0, n_bytes=0, priority=10,ip,in_port=4,dl_vlan=1,nw_dst=11.0.0.2,actions=group:6 duration=360s, n_packets=0, n_bytes=0, priority=4,ip,in_port=1,dl_vlan=1,nw_dst=11.0.0.2,actions=group:3 table_id=254, duration=527s, n_packets=0, n_bytes=0, priority=1,actions=drop table_id=254, duration=527s, n_packets=0, n_bytes=0, priority=0,reg0=0x3,actions=drop table_id=254, duration=527s, n_packets=0, n_bytes=0, priority=0,reg0=0x1,actions=controller(reason=no_match) table_id=254, duration=527s, n_packets=12, n_bytes=900, priority=0,reg0=0x2,actions=drop table_id=254, duration=527s, n_packets=0, n_bytes=0, priority=2,recirc_id=0,actions=resubmit(,0) Is there a policy for an ovs switch to drop a icmp packet? Because in Wireshark I am seeing packet 1 then 2 then 3 etc even though sometimes I am expecting to see both packets traversing the network at the same time. So I am assuming that maybe the icmp implementation in ovs is time sensitive? Or could it come from the fact that there is a port that is changing? Here is what I see in my controller (ryu): EVENT ofp_event->dpset EventOFPPortStatus DPSET: A port was modified.(datapath id = 0000000000000005, port number = 1) EVENT ofp_event->dpset EventOFPPortStatus DPSET: A port was modified.(datapath id = 0000000000000002, port number = 4) EVENT ofp_event->dpset EventOFPPortStatus DPSET: A port was modified.(datapath id = 0000000000000005, port number = 1) Thanks in advance for you help!
