I can't see the node and link in OpenFlow Topology when i add two PC to OpenFlow Switch, and ping PC A to B through a OpenFlow instance(that ping is success).
My Hardware & Software information :
OpenFlow Switch : HP 5130 EI Switch Firmware : Version 7.1.045, Release 3106
Controller : VAN Controller Version 2.4.6.0627 & Ubuntu 12.04.5
OpenFlow Negotiated Version : 1.3
--------------------------------------------------
In other way,it can display the node and link when i tried use Mininet to deploy the topology.
OpenFlow Negotiated Version : 1.0
MIninet vSwitch version : 1.4.6
I can controller the instance flow but just can't see the topology, I don't know where the configure is wrong.
