The text book example from CCO is:
(remember normal burst and extended burst are in bytes per second while the
desired rate is actually bits per second)
Normal burst = convert desired rate to bytes and multiply by 1.5
Extended burst = multiply normal burst by 2
Example
Desired outbound rate on an interface is 1Mbps
Desired rate in bytes = 125000
Normal burst = 187500 Bytes
Extended burst = 375000 Bytes
Rate-limit output 1000000 187500 375000 conform-action transmit exceed
action drop
Here is the link I used to derive these values.

Subject: QOS question from routopia lab 2
Hello Folks,
I have a QOS question :
1) Limit R8 to only upto 10% of its bandwidth for PING traffic .
I think that CBWFQ should be done here . But then again CBWFQ will assign
10% of teh bandwidth not limit the bandwidth . The solutions provided have
used CAR . But if you use CAR . what are the value of normal burst and max
burst to be used ?
Thanks
Akhilesh Verma
