Hi, Which match-fields are you setting in the Flow? For setting Source and Destination Port Addresses (tp_dst or tp_src), OpenFlow protocol requires you to set the Network Protocol (nw_proto) match-field as well. This field tells the datapath what header to expect next after the IP header. A nw_proto=6 indicate TCP packets, while nw_proto=17 indicate UDP. Once this field is set, the tp_dst and tp_src can be set and assigned value, otherwise these two fields are ignored/wildcarded by default.
You can read about it further on page 4 and page 8 of the OpenFlow switch specification document (version 1.0.0).
