Hi Yrineu, The logs seem clean, could you please take a wireshark dump to see if the flows are going over the wire and the switch is rejecting them ? Also
1. Are you installing multiple flows ? or a single flow? 2. What is the build against which you are testing?

Looking at the logs I see that the handshake initially fails but immediately succeeds in the next try. Apart of it, no errors or anything suspicious. My mininet topology is: $ sudo mn --controller=remote,ip=192.168.0.12 --topo linear,2 --switch ovsk,protocols=OpenFlow13 root@mininet-vm:~# ovs-vsctl show 018de162-474c-49f8-8f2d-9617d35a4195 Bridge "s2" Controller "ptcp:6635" Controller "tcp:192.168.0.12:6633<http://192.168.0.12:6633>" is_connected: true fail_mode: secure Port "s2" Interface "s2" type: internal Port "s2-eth1" Interface "s2-eth1" Port "s2-eth2" Interface "s2-eth2" Bridge "s1" Controller "tcp:192.168.0.12:6633<http://192.168.0.12:6633>" is_connected: true Controller "ptcp:6634" fail_mode: secure Port "s1-eth2" Interface "s1-eth2" Port "s1" Interface "s1" type: internal Port "s1-eth1" Interface "s1-eth1" ovs_version: "2.4.0" After everything installed nothing is added into the flow tables.

After Be, release the plugin model has changed, it’s the newer model now, and all functionality remains same. I went through both of your code snippets, and both look good!! Have a few questions though that would help us in drill down to the issue: 1. I assume that the flows are not going over the wire? Am I correct? 2. Are you installing multiple flows ? or a single flow? 3. What is the build against which you are testing? 4. Are there any errors/exceptions that you see in the logs : if not, could you please enable debug logs for openflowplugin as a. log:set DEBUG org.opendaylight.openflowplugin thanks Shuva From: [email protected]<mailto:[email protected]> [mailto:[email protected]<mailto:[email protected]>] On Behalf Of Yrineu Rodrigues Sent: Tuesday, November 22, 2016 4:26 AM To: Jozef Bacigál Cc: [email protected]<mailto:[email protected]>; [email protected]<mailto:[email protected]> Subject: Re: [openflowplugin-dev] ODL: NIC - Issues to create basic OpenFlow rules using OF Plugin Hi Jozef, Thanks for your fast response! On NIC project we have an OpenFlow renderer to create basic firewall rules, ARP reply and others. Here's<https://github.com/opendaylight/nic/blob/master/of-renderer/src/main/java/org/opendaylight/nic/of/renderer/impl/ArpFlowManager.java> an example of 'FlowBuilder' for ARP flows, and here's<https://github.com/opendaylight/nic/blob/master/of-renderer/src/main/java/org/opendaylight/nic/of/renderer/impl/AbstractFlowManager.java> the implementation of 'writeDataTransaction()'. My question is: Something has changed at 'FlowBuilder' creation, after 'Be' release? We need fill some new 'FlowBuilder' field, or change something at 'writeDataTransaction()' method? At this current implementation something is wrong and the OF rule isn't generated. Please, let me know if you need more info.

You question is too generic so maybe more information would help us to identify the problem you get and find together the best solution.

Maybe some example to create a "FlowBuilder" applying the Boron/Carbon changes would be helpful.
