Hi All, I am using the recent OVS 2.0 and a floodlight controller.
I created 2 bridges namely br-int and br-tun in a node and a flow based tunneling port on br-tun. After launching VMs on br-int , the floodlight is used to add broadcast flows in br-tun. But after adding a flow, i am getting switch disconnection event to controller from br-tun. I could see in controller logs an "Unexpected HELLO" message from OVS due to which its triggering switch disconnection. I didn't observe this behaviour with OVS 1.11. ERROR OpenflowController Controller$OFChannelHandler - Disconnecting switch OFSwitchImpl [/100.10.10.31:59267 DPID[00:00:9e:79:a1:5a:ea:48]] due to switch state error: Unexpected HELLO from OFSwitchImpl [/100.10.10.31:59267DPID[00:00:9e:79:a1:5a:ea:48]] DEBUG OpenflowController Controller - removeSwitch: OFSwitchImpl [/ 100.10.10.31:59267 DPID[00:00:9e:79:a1:5a:ea:48]] >From ovs-vswitchd logs, I could see echo_request/echo_reply logs when the channel is idle for 5 sec which is expected. >From OpenFlow Spec, I could see "Hello messages are exchanged between the switch and controller upon connection startup". Can someone please let me know if there are any other scenarios when the OVS could send HELLO to controller apart from start-up?? Thanks Eswar Rao
