Dear, Actually RYU controller can provide it. I have not tested yet but I found it. c*lass *ryu.ofproto.ofproto_v1_3_parser.NXActionRegLoad(*ofs_nbits*, *dst*, *value*, *type_=None*, *len_=None*, *experimenter=None*, *subtype=None*) I see this class can be used. This one is similar to the "*load*:*value*-> *dst**[**start*..*end* *]" of ovs-ofctl * On Mon, Aug 12, 2019, 2:32 AM Pedro Andres Aranda Gutierrez < pa...@gm...> wrote: > Thinking a bit, you may want to try tables.
