Hi,
I'm using the newer version of OVS though, I guess OVS does not supports the
OpenFlow 1.5 structured FlowStats message.
the FlowStats message was restructured in the OpenFlow 1.5 according to
introduction of the FlowDesc message, but OVS does not implement the new
structure of the FlowStats (looks like up to OF version 1.4 or earlier).
https://github.com/openvswitch/ovs/blob/bd916d13dbb845746983a6780da772154df647ba/lib/ofp-util.c#L2757-L2799
Also, the FlowDesc message does not seem to be supported, implementation not
found and the Extensible Flow Entry Statistics(EXT-334) is still on TODOs which
required to implement the FlowDesc message.
https://github.com/openvswitch/ovs/blob/master/Documentation/topics/openflow.rst#openflow-15-only
OVS seems to support the OpenFlow 1.5 partially...
Thanks,
Iwase

Hi,
Can you please let me know if there is any Fix for the below stated issue which
i see when i try to retrieve the Flow statistics using OFPFlowStatsRequest API
with OpenFlow version1.5.
Since this is blocking some features, it would be very helpful if there is any
fix for the following. Will be looking forward for your response.
Thanks,
Shivani Dommeti.

Hi,
Working on:
RYU version:3.27
Ovs version: 27.2
OpenFlow version:1.5.
I tried getting the statistics of each flow using the following API:
match = ofp_parser .OFPMatch(in_port=1)
req = ofp_parser .OFPFlowStatsRequest(datapath,0,1,ofp.OFPP_ANY
,ofp.OFPG_ANY,0,0,match)
And i see the following error:
EVENT ofp_event->Controller EventOFPErrorMsg
EVENT ofp_event->ofctl_service EventOFPErrorMsg
EventOFPErrorMsg received.

this.
