Chapter 1 CLI Command Reference
shape (percent)
shape (percent)
To specify average or peak rate traffic shaping on the basis of a percentage of bandwidth available on an
interface, use the shape command in policy-map class configuration mode. To remove traffic shaping,
use the no form of this command.
shape {average} percent percentage [sustained-burst-in-msec ms] [be excess-burst-in-msec ms]
[bc committed-burst-in-msec ms]
no shape {average} percent percentage [sustained-burst-in-msec ms] [be excess-burst-in-msec
ms] [bc committed-burst-in-msec ms]
Syntax Description
Command Default The default bc and be is 4 ms.
Command Modes Policy-map class configuration (config-pmap-c)
Command History
Usage Guidelines
Committed Information Rate
This command calculates the committed information rate (CIR) on the basis of a percentage of the
available bandwidth on the interface. Once a policy map is attached to the interface, the equivalent CIR
value in bits per second (bps) is calculated on the basis of the interface bandwidth and the percent value
entered with this command. The show policy-map interface command can then be used to verify the
CIR bps value calculated.
average Specifies average rate traffic shaping.
percent Specifies that a percent of bandwidth will be used for either the average
rate traffic shaping or peak rate traffic shaping.
percentage Specifies the bandwidth percentage. Valid range is a number from 1
to 100.
sustained-burst-in-msec (Optional) Sustained burst size used by the first token bucket for policing
traffic. Valid range is a number from 4 to 200.
ms (Optional) Indicates that the burst value is specified in milliseconds (ms).
be (Optional) Excess burst (be) size used by the second token bucket for
policing traffic.
excess-burst-in-msec (Optional) Specifies the be size in milliseconds. Valid range is a number
from 0 to 200.
bc (Optional) Committed burst (bc) size used by the first token bucket for
policing traffic.
committed-burst-in-msec (Optional) Specifies the bc value in milliseconds. Valid range is a number
from 1 to 2000.
Release Modification
15.1(2)SNG Support for this command was introduced on the Cisco ASR 901 router.
