The point was that both shaping and policing are "always on" if configured.
As opposed to the bandwidth command which is part of the "as congestion
occurs" mechanism of queuing.
Remember though, that the policing mechanism measures in more general terms
than shaping does. So while there is no queue involved, it still does a
decent job of handling the statistical differences of bursty traffic.

Scott,
Not sure if it has change, been a long time.
But to my understanding, police will drop the packet once the threshold is
breached. However with shape, it will store the packet which is above the
threshold for a certain time, to be transmitted once the token in the bucket
is available.
In short if you have a fluctuating traffic. With Police you will loose any
traffic that goes above the configure treshold, while shapping would
buffered the excess traffic in the buffer to be sent once the bandwidth is
available. (not sure how long the holding period is, never read any
specification).
Cheers,
Donny

It does the same thing as far as it will shape all the time (not just when
congestion), but shaping and policing are different processes for
functionality!

How about "shape" and "police" ?
They seem to do the same things.
