The 3550 only supports policing. It only support egress policing if your
class-map has a 'match any' clause in it. Otherwise it will silently reject
the service-policy output command IIRC.

It's lack of shaping isn't so much of a problem for us since must customers
don't come near the limits they want set - it's just so that they can ensure
that if their traffic patterns rise very suddenly they don't get stuck with
a bill they can't afford to pay.
