Hmm, the same thing happens using 0xffffffff. Yeah, something must be
wrong with the request since I can guarantee the flow is added before
it's sent.

and also looks the same as some code that I have that's working.. the
only difference is that I'm using
body.match.wildcards = 0xffffffff
although that shouldn't make a difference. But if you want you can try
it out

Interesting. I used Open vSwitch's ovs-ofctl dump-flows and I
can see the flow. I am waiting three seconds after installing
the flow before requesting the flow stats, so that should be
enough time...

Can you look at the flowtable using dpctl to verify that it
is empty?
( could it be the timing? are you sending the request right
after you send the flowmod?)

Oh, and I forgot to mention that I am sending a flow

Hello,
I am trying to add a flow to a switch in my Nox
component. After the switch joins the datapath, I
create a simple flow to test that it works:
flow = dict()
flow[NW_PROTO] = UDP_PROTOCOL
self.install_datapath_flow(dpid, flow,
OFP_FLOW_PERMANENT, OFP_FLOW_PERMANENT,
[[OFPAT_OUTPUT, [0, OFPP_CONTROLLER]]])
I then receive a flow stats reply event in my
handler, but event.flows = [] and event.flowcount =
0. Do you know what I am doing wrong?
Thank you,
Derek
