Hello,
I would like my module to receive a list of installed flows from an
OpenFlow switch. I already managed to receive the majority of that
information by utilizing the python flow fetcher app, but
unfortunately it won't show the actions associated with the flows.
pyglue.cc says that the action information is not implemented yet and
points at Flow_stats. From Flow_stats' v_actions I can get the action
header and from that the action type by adding
pyglue_setdict_string(dict, "actionlen",
to_python(ntohs(fs.v_actions[0].len)));
to pyglue's to_python(const Flow_stats& fs) method, but after that I
am stuck and can't find a way to get to information like the outport
of a OFPAT_OUTPUT action.
Moreover, it is irritating that the specification states that
ofp_flow_stats has an item 'actions', which is an array of
ofp_action_header elements. Does this imply, that there is no way to
get the actual ofp_action_output / ofp_action_enqueue / etc.
information?
So, is there a way to receive the complete action information?
Best regards,
Stanislav Lange
