5.1 Actual Bucket Size
When configuring a meter or shape rate, a fixed token bucket is also configured which is derived from the
committed rate, burst rate, and burst duration configured. If a burst duration is not configured, the largest
bucket size is automatically selected which would be 512K for a 10/100 Mbps or 1 GigE port. If you wish
to use another bucket size, you must calculate the burst duration by using the actual size of the bucket -
Sections 5.2 and 5.3 provide examples. The following table, Table 7, shown below displays the actual
bucket size in bytes.

5.2 Policing Traffic
When configuring traffic policing, the committed rate, burst rate, and burst duration can be configured
using the following command:
5530-24TFD(config)# qos meter <1-55000> committed-rate <64-10230000 Kbits/sec> max-
burst-rate <64-4294967295 Kbits/sec> max-burst-duration <1-4294967295 Milliseconds> in-
profile-action <1-55000> out-profile-action [<1-1>|<9-55000>]
QoS parameters:
Parameter
Description
<1-55000>
Enter an integer to specify the QoS meter; range is 1 to 55000.
name <WORD>
Specify name for meter; maximum is 16 alphanumeric
characters.
committed-rate
<64-10230000>
Specifies rate that traffic must not exceed for extended periods to
be considered in-profile. Enter the rate in Kb/s for in-profile traffic
in increments of 1000 Kbits/sec; range is 64 to 10230000
Kbits/sec.
max-burst-rate
<64-4294967295>
Specifies the largest burst of traffic that can be received in a
given time for the traffic to be considered in-profile. Used in
calculating the committed burst size. Enter the burst size in Kb/s
for in-profile traffic; range is 64 to 294967295 Kbits/sec
max-burst-duration
<1-4294967295>
Specifies the amount of time that the largest burst of traffic can
be received for the traffic to be considered in-profile. Used in
calculating the committed burst size. Enter the burst duration in
ms for in-profile traffic; range is 1 to 4294967295 ms.
in-profile-action <1-55000>
Specify the in-profile action ID; range is 1 to 55000.
