[ovs-discuss] OVS will not send ARP packets as packet-in to OpenFlow controller

[Ryan Izard]

Yep, we stumbled into that and it worked like a charm. We couldn't quite
tell from the document if in-band is enabled or disabled by default when
you install and bring up a bridge for the first time. Do you happen to know?

We have machines of our own at Clemson and Utah and in CloudLab and GENI.
We're running different experiments with different controllers and the
topologies are disjoint. I don't quite understand what would have caused
all the OVS's to get into this state.

In any event, thanks for you insight and help! I've learned a lot more
about OVS today :-)
