Hi Iwase, I would like to clarify something, the switch isn't directly connected to the controller .It is connected to a port on the same machine, and it receives all the packet out msg's from the controller. On the switch I don’t see any msg's, but the flows are being configured.
So the flows are configured as follows: $ ovs-ofctl -O OpenFlow13 dump-flows s1 OFPST_FLOW reply (OF1.3) (xid=0x2): cookie=0x0, duration=869.299s, table=0, n_packets=147, n_bytes=8820, priority=65535,dl_dst=01:80:c2:00:00:0e actions=CONTROLLER:65535 cookie=0x0, duration=848.41s, table=0, n_packets=0, n_bytes=0, priority=65534,in_port=1 actions=drop cookie=0x0, duration=850.767s, table=0, n_packets=0, n_bytes=0, priority=65534,in_port=2 actions=drop cookie=0x0, duration=869.495s, table=0, n_packets=2684, n_bytes=117158, priority=0 actions=CONTROLLER:65535 Is that the problem? Also the ovs version on both the environments are same i.e. version 2.0.2 . So I have configure the switches on the machines to match switch configuration on mininet, but still no luck.
