OVS shouldn't be deleting the flows. I suspect it's the controller. > Actually I find the flows will also be totally deleted after the OVS bridge > is disconnected from the controller. That surprises me. If by disconnected, you mean that the controller is still configured but not reachable, then you may be running into behavior based on the "fail_mode" described in ovs-vswitchd.conf.db. > Those pre-configured rules are important for my setup, is there any way to > keep these old flows after connecting to a controller?

OVS supports a flow monitoring extension that will inform the controller about flows that are added to it. A similar mechanism based on OVS's extension was added to OpenFlow 1.4 (and an extension to OpenFlow 1.3). You'd need to find out whether OpenDaylight support one of them. --Justin _______________________________________________ discuss mailing list [email protected] http://openvswitch.org/mailman/listinfo/discuss
