I am having some trouble in adding flow table entries with
openvswitch. I am using nox with some modifications on it and when I
submit flow mod message the switches appear to accept the packet
(all the methods to add the flow entry return 0), but when I use
ovs-dpctl dump-flows br0 it has no flows installed.
ovs-dpctl doesn't display OpenFlow flows. You can't use it this way.
ovs-ofctl displays OpenFlow flows. Use "ovs-ofctl dump-flows" to show
the flow table.
In the dpctl help one finds
/dump-flows DP display flows in DP/
Using this command with off-the shelf Nox it displays all flows. Anyway
if I can do dpctl dump-flows br0 when I try ofctl dump-flows br0 it
complains about non existing bridge or socket.
The vswitch daemon prints out:

Is this correct?
It looks like you're trying to match on TCP/UDP ports 0 but didn't
specify a protocol. That's probably a mistake
Yes very probably this is the mistake. I haven't used the wildcard.
