Hi Sergio, Could you try to run your application without flowvisor. I find it strange that flowvisor would be causing a problem here, even though it treats lldp packets rather awkwardly.
That said, if your setup works without flowvisor then we can definitely say that flowvisor is at fault and we can investigate further. -- Ali Al-Shabibi On 12 janv. 2012, at 04:24, Sergio Jiménez Feijóo <jjji...@gmail.com> wrote: > Hi guys, > > I've developed a NOX aplication which needs to use the topology component to > discover the network topology.
