Hi Kalai, >>> And only the openflowplugin master for a switch will receive the packets How so ? There is no indication from OF Spec (1.3.1 Section 6.3.4 is what I referred) that switches can send the packet-ins only to one of 3 controllers (assuming 3-node cluster). So, it can potentially be a spray depending upon switch implementation
Assuming that we have symmetric cluster - all features run on all nodes, any "packet-listening" feature instances across cluster nodes can get the notification since yang notifications are node-local.

In the a clustering environment, multiple controller nodes can be the master for the switches connected. And only the openflowplugin master for a switch will receive the packets and notify them to the openflowplugin dependent feature instance co-located in that controller node. So for a dependent feature to be cluster aware should it be tied to openflowplugin master? Or are there any other mechanism (like packet reception through Data change notifications) available so that the dependent feature can be universal master across all the cluster nodes Regards, K.Kalaiselvi
