hi,
perhaps you've already resolved your problem, but if not, I think there is a
typo in your rules below. I'll also put some debugging tips at the end.

hi,
hi Namal,
that error message doesn't give a lot of useful information, does it? :-/ from
some quick Googling, it seems like a problem to solve on your Windows computer
-- something about disabling security on the wireless interface. at any rate,
it does not appear to be an OpenFlow problem.

I think it's a place of ambiguity in the spec, perhaps. for example, with the

hi Adria,
unfortunately, yes, this problem has been seen before on the Pantou firmware. I
don't know that anyone has determined a root cause.
there are a couple workarounds:
1) have your controller send periodic ECHO_REQUEST's to the switch, rather than
wait for the switch to send them. for ex

hi Peter,
from later emails, it sounds like you have everything working. however, I do
want to mention one alternative that does not require changing the controller.
if you add:
