Hi RYU team, I am seeing following issue with RYU. I am testing flow stats request with vendor hardware switch using OF1.3.1
Step 1 : Pushed the below flow from RYU to switch. The flow gets installed
rightly.
curl -X POST -d '{"dpid": "71145865295808","priority":"1","match": {"in_port":
"2","dl_type":"34525","ipv6_src":"2001::/64","ipv6_dst":
"1001::1","nw_proto":"6","tcp_src":"1"},"actions": [{"type": "OUTPUT", "port":
"1"}]}' http://localhost:8080/stats/flowentry/add
This can be any type of flow for this matter.
Step2: Using the below curl command requested for flow stats.
curl -X GET http://localhost:8080/stats/flow/71145865295808
At this point, RYU cored with traceback and reseted the controller connection.
Attached the PCAP as well. Can you help troubleshoot or fix this issue w.r.t
to RYU?
