Hi Iwase Yusuke,
Thank you for the response.
Working on:
RYU version:3.27
Ovs version: 27.2
OpenFlow version:1.5.
I have tried to get the flow stats using OFPAggregateStatsRequest API and i
see the following error:
Encounter an error during parsing OpenFlow packet from switch.This implies
switch sending a malformed OpenFlow packet.version 0x06 msg_type 19 msg_len
40 xid 2049228120 buf 0x06 0x13 0x00 0x28 0x7a 0x24 0xbd 0x58 0x00 0x02

Fetching next instruction to send to CP
i see the OVS sending the stats :
2018-02-22T05:06:10.923Z|05694|vconn|DBG|tcp:127.0.0.1:6633: received:
OFPST_AGGREGATE request (OF1.5) (xid=0x6ba32021): table=1 in_port=193
2018-02-22T05:06:10.923Z|05695|vconn|DBG|tcp:127.0.0.1:6633: sent
(Success): OFPST_AGGREGATE reply (OF1.5) (xid=0x6ba32021): packet_count=0
byte_count=0 flow_count=2
is there any fix to get the stats for each flow on openflow version1.5
Tried with openflow version 1.3 and i see no issues.
Regards,
Shivani Dommeti.
