I am not sure about using shape peak command. Appreciate if someone can
share some clarification.
The most confusing fact is that if you configure "shape peak 512000",
without optional Bc and Be parrameters (i.e. using default), you are
actually allow traffic to burst to 1024K (double the configured rate).
R5#
!
policy-map SHAPE
class WEB
shape peak 512000
int s0/0
service-policy output SHAPE
R5# sh policy-map int s0/0
Serial0/0
Service-policy output: SHAPE
Class-map: WEB (match-all)
0 packets, 0 bytes
5 minute offered rate 0 bps, drop rate 0 bps
Match: protocol http
Traffic Shaping

Class-map: class-default (match-any)
223 packets, 2899 bytes

So how will you best answer this question?
Assign WEB traffic the minimum of 128K, and allow it to peak at 512K.
