+Q: My bridge disconnects from my controller on add-port/del-port.
+
+A: Reconfiguring your bridge can change your bridge's datapath-id because
+ Open vSwitch generates datapath-id from the MAC address of one of its ports.
+ In that case, Open vSwitch disconnects from controllers because there's
+ no graceful way to notify controllers about the change of datapath-id.
+
+ To avoid the behaviour, you can configure datapath-id manually.
+
+ ovs-vsctl set bridge br0 other-config:datapath-id=0123456789abcdef
