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

:26:55:da:3a:40]:[192.168.0.2>192.168.0.1])
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
