The show policy map command does not work on 3550s/3560s/3750s, which
are not capable of accounting at the processor what the silicon is doing...

That's why I said "small headed". And the reason why terminating a GRE
tunnel in them is a very bad idea.

The show mls qos interface xxx policer or stats does not show any data
even though the policing is taking place (as perceived by the traffic
behaviour).
