Hello, I am trying to use the openflow_webservice component to install flows matching nw_src and nw_dst. I run a POST command with match set for nw_src and nw_dst. When I inspect the flow table for the switch and I try to ping between the the src and dst, it doesn’t work however. I am wondering if I am using the set_table properly?
I am doing basically the same thing as this person https://www.mail-archive.com/pox-dev%40lists.noxrepo.org/msg01221.html <https://www.mail-archive.com/pox-dev@lists.noxrepo.org/msg01221.html>. Initially i had that issue too but then I switched to the eel branch and I passed that issue. But now I have run into an issue where it doesn’t seem like the entries are being installed properly. I am on the eel branch. I am running pox with the following: ./pox.py log.level --DEBUG web.webcore openflow.webservice Then I run the following: curl -i -X POST -d '{"method": "set_table”, "params": { "dpid": "00-00-00-00-00-01”, "flows": [{"actions": [{"type": "OFPAT_OUTPUT", "port": 1}], "match": {"nw_src": "10.0.0.1", "nw_dst": "10.0.0.2"}}]}, "id": 1}’ http://192.168.56.103:8000/OF/ <http://192.168.56.103:8000/OF/> This runs successfully as I get the following response. HTTP/1.1 200 OK Server: BaseHTTP/0.3 Python/2.7.4 Date: Sun, 07 Dec 2014 23:01:50 GMT Content-Type: application/json Content-Length: 68 {"result": {"flowmod": true, "dpid": "00-00-00-00-00-01"}, "id": 1} Then I run the following command to see the flow table of the switch 00-00-00-00-00-0: url -i -X POST -d '{"method": "get_flow_stats", "params": {"dpid": "00-00-00-00-00-01"}, "id": 1}' http://192.168.56.103:8000/OF/ <http://192.168.56.103:8000/OF/> HTTP/1.1 200 OK Server: BaseHTTP/0.3 Python/2.7.4 Date: Sun, 07 Dec 2014 23:01:55 GMT Content-Type: application/json Content-Length: 313 {"result": {"flowstats": [{"packet_count": 0, "hard_timeout": 0, "byte_count": 0, "duration_sec": 4, "actions": [{"max_len": 0, "type": "OFPAT_OUTPUT", "port": 1}], "duration_nsec": 652000000, "priority": 32768, "idle_timeout": 0, "cookie": 0, "table_id": 0, "match": {}}], "dpid": "00-00-00-00-00-01"}, "id": 1} As one can see above, in when I sent a POST request, i set “nw_dst”: “10.0.0.2” and “nw_dst”: “10.0.0.2” but the flow table entry shows that the match is empty. I tried pinging between h1 and h2 but the destination is unreachable. Am I using the nw_src and nw_dst parameters correctly? What is the correct manner to set them? Aaron Lam
