Hi, are you running 'discovery' or any other application that has discovery as a dependency? If so, the packet_ins you see are most probably the control (LLDP) packets sent by discovery to discover neighbors. ( http://noxrepo.org/noxwiki/index.php/Discovery )
the flow expiration time is set from the controller, when you send the flow_mods. The flow_mod includes arguments to set hard/idle timeout for the entry. 'Idle timeout' means the entry will expire X seconds after no matching traffic has hit the switch, 'hard timeout' means it will expire in X seconds no matter what. (Section 5.5.3 in http://www.openflow.org/documents/openflow-spec-v1.0.0.pdf ) On Thu, Oct 20, 2011 at 1:27 PM, Candy Floss <cndf...@gmail.com> wrote: > I have copnnected NOX and two switches.
