This seems to be the problem on the Lagopus side... For making sure that Ryu can install the flows correctly, please check the flow entries by using ofctl_rest.py. e.g.) # Run rest_firewall and ofctl_rest $ ryu-manager ryu.app.rest_firewall ryu.app.ofctl_rest # Enable firewall on switch dpid=1 $ curl -X PUT http://localhost:8080/firewall/module/enable/0000000000000001 # Install rules for ICMP connectivity. # The following is sample rules from Ryu-Book. $ curl -X POST -d '{"nw_src": "10.0.0.1/32", "nw_dst": "10.0.0.2/32", "nw_proto": "ICMP"}' http://localhost:8080/firewall/rules/0000000000000001 $ curl -X POST -d '{"nw_src": "10.0.0.2/32", "nw_dst": "10.0.0.1/32", "nw_proto": "ICMP"}' http://localhost:8080/firewall/rules/0000000000000001 # Confirm the flows. $ curl -X GET http://localhost:8080/stats/flow/1 | python -m json.tool { "1": [ { "actions": [ "OUTPUT:NORMAL" ], "byte_count": 168, "cookie": 0, "duration_nsec": 105000000, "duration_sec": 488, "flags": 0, "hard_timeout": 0, "idle_timeout": 0, "length": 88, "match": { "dl_type": 2054 }, "packet_count": 4, # Packet count should be incremented "priority": 65534, "table_id": 0 }, { "actions": [ "OUTPUT:NORMAL" ], "byte_count": 294, "cookie": 1, "duration_nsec": 268000000, "duration_sec": 439, "flags": 0, "hard_timeout": 0, "idle_timeout": 0, "length": 104, "match": { "dl_type": 2048, "nw_dst": "10.0.0.2", "nw_proto": 1, "nw_src": "10.0.0.1" }, "packet_count": 3, # Packet count should be incremented "priority": 1, "table_id": 0 }, { "actions": [ "OUTPUT:NORMAL" ], "byte_count": 294, "cookie": 2, "duration_nsec": 882000000, "duration_sec": 429, "flags": 0, "hard_timeout": 0, "idle_timeout": 0, "length": 104, "match": { "dl_type": 2048, "nw_dst": "10.0.0.1", "nw_proto": 1, "nw_src": "10.0.0.2" }, "packet_count": 3, # Packet count should be incremented "priority": 1, "table_id": 0 }, { "actions": [ "OUTPUT:CONTROLLER" ], "byte_count": 0, "cookie": 0, "duration_nsec": 105000000, "duration_sec": 488, "flags": 0, "hard_timeout": 0, "idle_timeout": 0, "length": 80, "match": {}, "packet_count": 0, "priority": 0, "table_id": 0 } ] } If ping (ICPM packets) can communicate, "packet_count" fields should be incremented. And if the flow is installed as expected and packet counts are not incremented, Lagopus might drop packets or not make matching packets to the flow.
