NOX only speak OpenFlow, but the switch is connecting with the management protocol. The argument you're passing to ovs-vswitchd should be to a configuration database instance (created by ovsdb-server).
You should get ovsdb-server and ovs-vswitchd running and talking together on your local box as described in INSTAL.Linux. Once you do that, you can tell OVS to connect to a controller with the "ovs-vsctl set-controller" command, as described in the ovs-vsctl man page. --Justin On Nov 19, 2011, at 1:06 PM, Theophilus Benson wrote: > I am trying to connect an openvswitch to a nox controller, but I get a JSON > related error.
