If the new and old rule have the same priority, the new rule overwrites the old rule. If the new and old rule have different priorities, there is no conflict: the new rule will be added to the flow table, the old rule will still be in the flow table. OpenFlow doesn't provide an option for other behavior. _______________________________________________ discuss mailing list [email protected] http://openvswitch.org/mailman/listinfo/discuss
