Hi Qingyu,
If Ryu works well on the Mininet topology, please confirm the packets sent from
your hardware
switches.
For example, capture the incoming packets using Wireshark or tcpdump on the
controller host,
then check of the incoming the Packet-In messages have the empty data.
If no data body, this problem is on your switch side.
Thanks,
Iwase

Hi guys,
Recently I’m using Ryu for a project. It works very well in my virtual environment (Mininet). Now
I’m trying move it into a “real” testbed (in fact it provides Openflow switch by OVX). But now I get
a big trouble. Controller can received switch features, and can get packet_in event. It contains
everything, but the msg in it, which should has ethernet packet information, is empty, which means
_msg = “”_ . If I install a miss-table into switch for just FLOOD output everything, nodes can ping
each other directly.
Anyone have idea?
By the way, the Version of Openflow is 1.0. And this testbed is working well since other people are
using it.
Best reagards,
Qingyu
