To send Packet-In messages to Ryu with only packet header data, please specify "max_len" in output action with the packet header length. http://ryu.readthedocs.org/en/latest/ofproto_v1_3_ref.html#ryu.ofproto.ofproto_v1_3_parser.OFPActionOutput e.g.) OFPActionOutput(port=ofproto.OFPP_CONTROLLER, max_len=68) For the packet header length, Wireshark project recommends 68 bytes for IPv4 packets and 96 bytes for IPv6 packets. https://wiki.wireshark.org/SnapLen Thanks, Iwase > > * * > > *OR* > > * * > > *Could I send just the packet header to the controller?* > > * * > > *Thanks for help* > > * * > > > > Anees AL-Najjar > > RHD Student > > School of Information Technology and Electrical Engineering (ITEE) > > Office: 331, Building (78) > > University of Queensland > > Brisbane, QLD > > Australia > > > > Emails: 1- [email protected] <mailto:[email protected]> > > [email protected] <mailto:[email protected]> > > Mobile: +61420407168 > > > > > > ------------------------------------------------------------------------------ > > > > _______________________________________________ > Ryu-devel mailing list > [email protected] > https://lists.sourceforge.net/lists/listinfo/ryu-devel > ------------------------------------------------------------------------------ Transform Data into Opportunity.
