I have successfully connected my switches( s1 ------ s2) to Controller-helium . GUI is displaying both of switches But the inter-connecting link and the hosts connected to the switches are not shown , even when I ping between the hosts . Do I have to run discovery protocols (eg LLDP) on my switches ??? or does OPENFLOW msgs help in topo discovery ???
I would appreciate if somebody can help me out with the topology discovery mechanism of controller .
Thanks & regards Harsha
