Hi, I'm Hssan and working on an SDN lab. I have 2 NetFPGA switches and an Open vSwitch all connected to a Floodlight controller. Switch has a host connected to it. All the switches are connected to each others with patch cables. Floodlight is running L2Switch. >From the topology of the controller, there is no connection between two switches, and hosts are shown as connected to wrong switches. But on the other side, all host ping each others.
Why Floodlight can't seem to recognize the real topology? Must I use crossover cables? Thanks in advance! Best Regards, Hssan
