Shape does not drop packets but queues them unless of course the queue is
full.
Shape average does not burst
Shape peak would allow burst but again, it does queuing not policing
Police 128000 bc 4000 is correct
The 4000 is in bytes.
If you enter police 128000 4000, then look at your config it is replaced
with "police 128000 bc 4000"

I think both of the answers doesnt allow the burst of 32kbps i.e. 1/4th of
128kbps. As per me, if i say police cir 128000 bc 4000 be 1000 will allow
the burst of 32kbps. Similarly in shaping taking the Tc as 1/8 i.e. 125ms
the bc = 16000 bits and be= 4000 bits.
thx
