If you are talking about OpenFlow 1.0, then the flow table cannot be specified. In OpenFlow 1.0, the arrangement of flow tables is meant to explain the internal structure of the switch, and the switch is allowed to place a flow in whichever flow table it believes best suits that flow. In OpenFlow 1.1, the situation is different. I believe that it is possible to place a flow in a specific table. I don't know how to do that with the reference switch; I would have to look it up there also. _______________________________________________ openflow-discuss mailing list [email protected] https://mailman.stanford.edu/mailman/listinfo/openflow-discuss
