Hi Ben,
First, I need to say I am using OpenFlow 1.3.
I am relieved to hear OVS should buffer.
I guess there are some misunderstanding in my side.
But at least what I am facing is difference between switch@trema-edge
and ovs.
With same controller, the switch from trema-edge specifies buffer_id
while ovs does not.
I will send you the captured packets personally, I appreciate very much
for your investigataion.
Best Regards,
...hiroshi miyata

I am now trying to run OVS of Kernel module with
Trema-edge(learning_switch code).
Both are in a box. (Ubuntu 12.10)
When I see the of13 packets, the buffer_id in packet_in messages are
0xffffffff(OPF_NO_BUFFER)
for both IPv4 packets and IPv6 packets.
Is it possible to make OVS buffer the packets?
OVS should be buffering packets. I am surprised to hear that it is
not.
Are these packets from flow misses or as a result of output to
OFPP_CONTROLLER? OVS only buffers packets that result from flow misses.
