Hi Ricardo and ikf, Thanks for the refresh. I think ikf was trying to install the flow entry and it is not matching for some reason. But the refresh is definitely useful.
Btw, I am replying just to correct a typo. You should return STOP to drop the packets, not CONTINUE. And do check nox.xml or nox.json in src/etc to ensure the order of the component being called by Packet_in_event. It is always cool to see the community chipping in. Allow me to say thanks to everyone that have done so, and hope others will help out too. THANKS. Regards KK On 12 July 2010 08:37, Ricardo Bennesby <ricardo.benne...@gmail.com> wrote: > Hello ikf.
