Hi Ali,

Thanks for your reply. After install wireshark and OpenFlow plugin, the
problem is solved. Still do not know the reason although we restart the
FlowVisor service. But now we find another error messages when using curl
to add a flow entry into Floodlight. The content of entry and the error
message are shown as below.

curl -d '{"switch": "00:00:fa:d7:c0:a2:7f:4a", "name":"flow-mod-2",
"cookie":"0", "priority":"32768", "ingress-port":"4", "vlan-id":"775",
"active":"true", "actions":"strip-vlan,output=2"}'
