Hi, I am trying integrate openvswitch with floodlight OF controller. TCP connection is established temporarily but then openvswitch is disconnecting and re-initiating the connection in loop.
Following is the openvswitch logs. floodlight host IP is 169.254.204.53/16 while openvswitch bridge IP is assigned as 169.254.204.54/16. ping works fine. Nov 1 13:05:35 testframe ovs-vswitchd: ovs|07705|fail_open|INFO|Still in fail-open mode after 2699 seconds disconnected from controller Nov 1 13:05:40 testframe ovs-vswitchd: ovs|07707|rconn|INFO|br0<->tcp: 169.254.204.53:6653: connected Nov 1 13:05:40 testframe ovs-vswitchd: ovs|07708|fail_open|WARN|No longer in fail-open mode Nov 1 13:05:50 testframe ovs-vswitchd: ovs|07710|rconn|ERR|br0<->tcp: 169.254.204.53:6653: no response to inactivity probe after 5 seconds, disconnecting Nov 1 13:05:51 testframe ovs-vswitchd: ovs|07711|rconn|INFO|br0<->tcp: 169.254.204.53:6653: connecting...

I have attached the pcap. OFPT_HELLO, OFPT_FEATURES_REQUEST,OFPT_GET_CONFIG_REQUEST all works fine. But both the floodlight controller and openvswitch are sending OFPT_ECHO to each other but no one sending out the OFPT_ECHO_REPLY. Any one faced the similar issue? Any help/clue ? Thanks & Regards, Subrata
