Hello. I have created a python file to test with OpenFlow 1.5. My file is like the simple_switch_14.py but I added the v15 parser and I change the version in the app. I create the topology, enable the switch to can support OpenFlow 1.5 and then I open the application simple_switch_15.py. It come onto main mode but give me this error: pack into requires exactly 4 arguments The Hello and config messages I think that are OK, but then they give me this code when I am doing ping (I use ovs-ofctl snoop to capture the code). root@ryu-vm:~# ovs-ofctl snoop s1OFPT_FEATURES_REQUEST (OF1.5) (xid=0x1b0f89a3):OFPT_FEATURES_REPLY (OF1.5) (xid=0x1b0f89a3): dpid:0000000000000001n_tables:254, n_buffers:256capabilities: FLOW_STATS TABLE_STATS PORT_STATS GROUP_STATS QUEUE_STATSOFPT_SET_CONFIG (OF1.5) (xid=0x1b0f89a4): frags=normal miss_send_len=128OFPST_PORT_DESC request (OF1.5) (xid=0x1b0f89a5): port=ANYOFPST_PORT_DESC reply (OF1.5) (xid=0x1b0f89a5): 1(s1-eth1): addr:7a:d1:16:c2:be:8a config: 0 state: 0 current: 10GB-FD COPPER speed: 10000 Mbps now, 0 Mbps max 2(s1-eth2): addr:76:d2:87:51:2e:f3 config: 0 state: 0 current: 10GB-FD COPPER speed: 10000 Mbps now, 0 Mbps max 3(s1-eth3): addr:7e:ce:f0:5d:d5:e5 config: 0 state: 0 current: 10GB-FD COPPER speed: 10000 Mbps now, 0 Mbps max LOCAL(s1): addr:f2:0b:e8:13:31:4d config: PORT_DOWN state: LINK_DOWN speed: 0 Mbps now, 0 Mbps maxOFPT_FLOW_MOD (OF1.5) (xid=0x1b0f89a6): ADD priority=0 out_port:0 actions=CONTROLLER:65535OFPT_PACKET_IN (OF1.5) (xid=0x0): cookie=0x0 total_len=98 in_port=1 (via no_match) data_len=98 buffer=0x00000100icmp,vlan_tci=0x0000,dl_src=00:00:00:00:00:01,dl_dst=00:00:00:00:00:02,nw_src=10.0.0.1,nw_dst=10.0.0.2,nw_tos=0,nw_ecn=0,nw_ttl=64,icmp_type=8,icmp_code=0 icmp_csum:1eb5OFPT_ECHO_REQUEST (OF1.5) (xid=0x0): 0 bytes of payloadOFPT_ECHO_REPLY (OF1.5) (xid=0x0): 0 bytes of payloadOFPT_PACKET_IN (OF1.5) (xid=0x0): cookie=0x0 total_len=98 in_port=1 (via no_match) data_len=98 buffer=0x00000101icmp,vlan_tci=0x0000,dl_src=00:00:00:00:00:01,dl_dst=00:00:00:00:00:02,nw_src=10.0.0.1,nw_dst=10.0.0.2,nw_tos=0,nw_ecn=0,nw_ttl=64,icmp_type=8,icmp_code=0 icmp_csum:5596OFPT_PACKET_IN (OF1.5) (xid=0x0): cookie=0x0 total_len=98 in_port=1 (via no_match) data_len=98 buffer=0x00000102icmp,vlan_tci=0x0000,dl_src=00:00:00:00:00:01,dl_dst=00:00:00:00:00:02,nw_src=10.0.0.1,nw_dst=10.0.0.2,nw_tos=0,nw_ecn=0,nw_ttl=64,icmp_type=8,icmp_code=0 icmp_csum:6d74OFPT_PACKET_IN (OF1.5) (xid=0x0): cookie=0x0 total_len=98 in_port=1 (via no_match) data_len=98 buffer=0x00000103icmp,vlan_tci=0x0000,dl_src=00:00:00:00:00:01,dl_dst=00:00:00:00:00:02,nw_src=10.0.0.1,nw_dst=10.0.0.2,nw_tos=0,nw_ecn=0,nw_ttl=64,icmp_type=8,icmp_code=0 icmp_csum:8059 I am using master version of OvS and RYU.
