Hi KK,
we are running the pyswitch and the packetdump module for testing. It
works fine for the reference software switch.
I am not sure wether this is a problem of the netfpga or nox-related.
I'll do a tcpdump in the morning.
Thx.
Michael

Hi,
I am assuming you are running some Python module. Can you tell us
which modules you are running? A tcpdump of the controller traffic
might help too. Can you also run just switch or routing that as C?
Thanks.
Regards
KK

Hi all,
first off, I'm sorry, if this has been answered before, but Google didn't
turn up any results and I don't have the time to scan all posts.
We have recently switched to OF 1.0 from 0.89 and are running the current
git version of the Nox branch for OpenFlow 1.0 as a controller for our
NetFPGA OpenFlow switch. We have two machines connected to the switch and as
a basic test wanted them to ping each other. Using dpctl to configure flow
rules manually this works flawlessly. However, when the Nox Controller is
connected to the datapath, the intial arp-reply packet is dropped by the
controller because of an invalid ethernet address:
00084|openflow-event|DBG:received packet-in event from 0023207f7017 (len:60)
invalid ethernet addr

My guess would be, that the vendor code resolution displayed here causes the
problem. However, I am not sure wether this is the case and in which library
this happens. Any ideas ?
Regards,
Michael
