Hi All,
I am facing issues when i try to establish connection between switch
and the latest RYU controller. The switch supports 1.0 and 1.3 versions
only. In this test, 1.3 has been configured on the switch. When the switch
initiates a HELLO packet (with 1.0 and 1.3 set in the bitmap), the RYU
responds with a HELLO with 1.5 version in its OpenFlow header (and without
a bitmap) leading to the connection rejection from the switch (as the
switch doesnt support 1.5 yet). I remember an older version of the RYU used
to work fine with the same switch (negotiate to 1.3). Can you please help
identifying where the issue is.Attached is the dump1.pcap file between the switch and the controller. 20.1.1.2 is the switch and 20.1.1.20 is the RYU. Packet no 4 is the HELLO packet send from the switch and packet no 8 is the HELLO packet from the RYU. Can someone please have a look and help me figure where the problem is? With the switch or the controller? Thanks, Nitish
