TO SET TRAFFIC SHAPING
The main objective of the traffic shaper is to allow the traffic in to the network at a
controlled rate from different sources so that the network resources are optimally
utilized for better performance. Typically this is achieved by applying a Token
Bucket Filter at the egress of an interface. Tokens will be generated per each flow
at a sustained rate (configured as CIR) and are emptied as and when the packets
are transmitted.

ALU(config-qos-P1-C1)# shape committed-rate 500000
committed-burst 7812
ALU(config-qos-P1-C1)# no shape
Command (in Class Mode) Description
shape committed-rate <8000-
10000000> committed-burst <40-
200000> peak-rate <8000-10000000>
excess-burst <40-200000>
This command sets QoS shaping
parameters on the policy map’s
traffic class.
Note: It is preferable to
configure committed
burst/excess burst as
125 milliseconds of
the specified
committed/peak rate.
For example, if
committed rate is 500
kbps, then committed
burst will be
((500000/8)*125/
1000) = 7812 bytes.
no shape This command removes the
configured shaping parameters.
