Hi, I have been trying to use conntrack with RYU and I am experiencing the following error messages. I am using a simple match statement and the ActionCT as given on the Ryu's documents page but that is giving me the following errors. I have tried using ovs verion 2.10 as well but no success. Could you please give me an example working code that I can use? 1. EVENT ofp_event->SimpleSwitch13 EventOFPPacketIn 2. packet in 2 00:00:00:00:00:04 00:00:00:00:00:03 2 3.

I just tried with a small change in this section and it didn't work. 1. if dst in self.mac_to_port[dpid]: 2. out_port = self.mac_to_port[dpid][dst] 3. else: 4. out_port = ofproto.OFPP_FLOOD 5. 6. 7. actions = [parser.OFPActionOutput(out_port)] 8. 9. # install a flow to avoid packet_in next time 10. if out_port != ofproto.OFPP_FLOOD: 11. match = parser.OFPMatch(ct_state=(0, 32)) 12. actions += [parser.NXActionCT( 13. flags=1, 14. zone_src="reg0", 15. zone_ofs_nbits=nicira_ext.ofs_nbits(4, 31), 16. recirc_table=4, 17. alg=0, 18. actions=[])] 19. if msg.buffer_id != ofproto.OFP_NO_BUFFER: 20. self.add_flow(datapath, 1, match, actions, msg.buffer_id) 21. return 22. else: 23. self.add_flow(datapath, 1, match, actions) Thanks in advance and looking for help Tauseef
