Hi Fujita San,
I ran the L2.py to set up the L2 switch & set up two flows between port
1 & 2. on our switch using the following OVS commands:
ovs-ofctl add-flow br0 in_port=1,actions=output:2
ovs-ofctl add-flow br0 in_port=2,actions=output:1
I connected 2 PCs on port 1 & port 2 and expected ping to work between
them, but ping failed. I thought maybe the ARP packets may be going to
the controller thru packet in messages, but I did not see any packets in
that direction. Any suggestion on how to debug further?
Thanks
David
