5.3 Interface Shaper

When configuring interface shaping, the shape rate, burst rate, and burst duration can be configured
using the following command:
5530-24TFD(config)# interface fastEthernet all
5530-24TFD(config-if)# qos if-shaper port <port #> shape-rate <64-10230000 Kbits/ sec>
max-burst-rate <64-4294967295 Kbits/ sec> max-burst-duration <1-4294967295
milliseconds>
QoS interfac e shaping parameters:

shape-rate
<64-10230000>
max-burst-rate
<64-4294967295>
max-burst-duration
<1-4294967295>
When configuring interface shaping on an interface, please note the following:
The maximum burst rat e cannot be configured the same as the shape rate. You must always
specify a higher maximum burst rate than the shape rate
The maximum burst rat e and burst duration is used to calculate the bucket size or committed
burst in bytes
The maximum burst rat e and burst duration is used to calculate the bucket size or committed
burst in bytes
Duration = ((bucketSize*8) / (max-burst-rate – committed-rate))
