ODL-Lithium-SR2: FLOW_MOD messages

Hi,

I have a Mininet Topology on a VM and the OpedDaylight controller (Lithium-SR2) on another VM. VMs can communicate via a private network (each VM has its private IP address). The Mininet network is connected to the OpedDaylight controller (as a RemoteController) on port 6633. The connection works and hosts can communicate ("ping" works fine).

I'm trying to find out the controller behaviour: my network has only 2 hosts and 5 switches as you can see here: image description

I captured the OpenFlow (1.0) traffic with "tcpdump" tool and I would like to see (in Wireshark) FLOWMOD messages to know which switch is on the path between hosts... but there aren't FLOWMOD messages!

A "ping" command in Mininet generates ARP and ICMP traffic. When a host sends a ARPREPLY with its MAC address, the switch which receives this message has to send a PACKETIN to the controller, which has to respond with a FLOW_MOD message (but there isn't).

Does OpenDaylight support topologies with loops? Does anyone have the same problem?

Thanks
