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 interface shaping parameters:
Parameter
Description
<portlist>
Ports to configure shaping parameters.
<WORD>
Specify name for if-shaper; maximum is 16 alphanumeric characters.
shape-rate
<64-10230000>
Shaping rate in kilobits/sec; range is 64-10230000 kilobits/sec.
max-burst-rate
<64-4294967295>
Maximum burst rate in kilobits/sec; range is 64-4294967295Kbits/sec.
max-burst-duration
<1-4294967295>
Maximum burst duration in milliseconds; range is 1 to 4294967295 ms.
When configuring interface shaping on an interface, please note the following:
The maximum burst rate 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 rate and burst duration is used to calculate the bucket size or committed
burst in bytes
The maximum burst rate and burst duration is used to calculate the bucket size or committed
burst in bytes
o Duration = ((bucketSize*8) / (max-burst-rate – committed-rate))
