Hi Namgon, If you change discovery.py +330 (or around there):
from: self.send_openflow_packet(dp, packets[dp][port].tostring(), port) to self.send_openflow_packet(dp, packets[dp][port].tostring(), port, openflow.OFPP_LOCAL ) Does it discover all the links? Aaron P.S: you may have to add import nox.lib.openflow as openflow at the top.
