ah! ok, so... that's a bit of a bummer, I didn't see this sort of
thing documented in the release-notes, though I admit to quick-skim :(
I suppose I'm really opposed to a mounds turning into an almond joy on
me without pretty clear notice.

our standard config was 0 & 1 .. so we just went with that :(
good thing there's a 2 & 3 though :)

I think we don't actually do the ELS functions, and at other places
i've run into the QFX I hadn't notice this problem either, but... I
also don't deploy switch stacks (voodoo!) and we happen to treat the
qfx more like a tiny router ... that has a slew of lan ports :(

ok, cool.. this would be handy for 'not this time' switch installs :)
I think I'll also just update my 'make me a switch!' script to just do
the right thing here... we were over eager and tried to mangle the config
by hand.. oops.

oh,that's pretty neat.. i think we just whack on the port types with
an apply-group choice (and then add the vlan, of course). I tried to keep the ports 'simple':
  TRUNK-PORT -> carry all vlans, used to link to the core.
  EDGE-PORT -> connect hosts, don't trunk...

we aren't 100% that simple, but.. mostly :)

ah. .I'll see how the now-working-ports 3400 fares, hopefully less
headaches than so far ;)

thanks! (for also making me re-think and find the other ports
solution) -chris
