Hi, This is because you are trying to add a kernel datapath on a userspace switch. I do not see this pair of commands being used in the link you provided (http://www.openflow.org/foswiki/bin/view/OpenFlow/Deployment/HOWTO/LabSetup). Any reason for doing so?
/var/run/dp0 is the UNIX domain socket to communicate to the switch with. You need it when you run ofprotocol. And the datapath id is 004E46324304. The userspace switch supports only one datapath from what I recall. Regards KK PS>> Please don't drop the mailing list.
