[ovs-discuss] Openvswitch Openflow version mismatch

[S.Liu at t-systems.com]

Hi all,

 

I'm having some troubles getting ryu openflow controller to work with
OVS. 

 

I'm running ryu controller 1.2 python sample script.  On OVS side I use
the latest version 1.9.90.   I was able to use "ovs-vsctl set Bridge br0
protocols=OpenFlow12" to add the OF12 support on the OVS.  However when
I run the controller ryu script, OVS complained version negotiation
failed.   I'm not sure why OVS said it support version 0x01, not version
0x03 even though I have enabled OpenFlow12 support there.   Also from
wireshark, both sides did claim version 0x03 in their OFP hello packets.


 

Any idea what the problem is?

 

Thanks a lot,

Steve
