回复： [openflowplugin-dev] [All channel inactive]Switch concurrencyconnect to odl and all others switch disconnected problem

Hi Luis Gomez:

Thanks for your remind. You are right.
After setting OVS inactivity_probe parameter to 0,  the problem relief. This is not openflowjava or openflowplugin bug.

The message below indicates the switch disconnects, since this is OVS, can you check in the OVS log (e.g. ovs-vswitchd.log) the reason for the disconnect? If the reason is timeout receiving echo response from controller, this means controller is too busy to respond to switch echos in which case switch disconnects and reconnects back making things worse. If that is the problem can you try the same scenario after setting the OVS inactivity_probe parameter to 0?
