I'm gonna check this solution tomorrow when I get back to work.. =) I did add discovery to NOX command line and links did not show up =(
I am using openvswitch v1.2.1.. Maybe it's some type of incompatibility? Anyway, I am going to install original openflow as well in order to check if links show up or not. If it does, I will talk to openvswitch people to solve this problem. STP and Flowtracer I will check tomorrow too. Thanks!
