Hi Team,

We are using Open Daylight Controller and OVS switch. ODL – Helium OVS Version: 2.3.1

We are running UDP traffic. After some time we observed that switch is getting re-connected and it is sending Hello Message to ODL. On ODL logs getting printed are:

2015-08-25 16:43:28,965 | INFO | entLoopGroup-8-7 | ConnectionAdapterImpl | 252 - org.opendaylight.openflowjava.openflow-protocol-impl - 0.6.0.SNAPSHOT | Hello received / branch 2015-08-25 16:43:29,027 | WARN | entLoopGroup-8-7 | OFSessionUtil | 254 - org.opendaylight.openflowplugin - 0.1.0.SNAPSHOT | duplicate datapathId occured while registering new switch session: 5 2015-08-25 16:43:29,030 | WARN | entLoopGroup-8-7 | ConnectionConductorImpl | 254 - org.opendaylight.openflowplugin - 0.1.0.SNAPSHOT | Closing handshake context failed: null

We request you all to please help us to resolve this error.

Thanks in advance.

which version of OF you are using.. because latest ovs supports openflow 1.4 and opendaylight still supports 1.3. So it will fail while handshaking if proper ovs is not used.
