Thanks kk yap. That's why I feel confusion. So, using the LLDP packet to probe the environment then what information will be get? or what format event will receive in controller. Because I really want to know it, but don't have any manner or spec. can explain it. Regards Ian 2010/4/15 kk yap

Dear all: Sorry to bother to everyone. But I am very interested about the NOX Controller can use discovery to find the complete topology. But the related sites are not very detailed description of its process. Anyone can tell me in detail how it is done? research http://noxrepo.org/manual/app-inde
