shape average
shape average
To configure class-based or port shaping by specifying the average traffic shaping rate or percentage, use
the shape average command in policy-map class configuration mode. To set port shaping, use the
command with the class class-default. To remove traffic shaping, use the no form of this command.
shape average {target bps | percent value}
no shape average {target bps | percent value}
Syntax Description
Defaults No traffic shaping is defined.
Command Modes Policy-map class configuration
Command History
Usage Guidelines You use the shape average policy-map class command to control output traffic. Shaping is not supported
in input policy maps.
Traffic shaping limits the rate of transmission of data. Configuring traffic shaping for a user-defined
class or class-default for class-based shaping sets the peak information rate (PIR) for that class.
Configuring traffic shaping for the class class-default when it is the only class in the policy map that is
attached to an interface sets the PIR for the interface (port shaping).
You cannot configure shape average in a class that includes priority queueing (configured with the
priority policy-map class configuration command).
The shape average command uses a default queue limit for the class. You can change the queue limit by
using the queue-limit policy-map class command, overriding the default that is set by the shape average
command.
Port shaping is applied to all traffic leaving an interface. It uses a policy map with only class default
when the maximum bandwidth for the port is specified by using the shape average command. A child
policy can be attached to the class-default in a hierarchical policy map format to specify class-based and
VLAN-based actions.
To return to policy-map configuration mode, use the exit command. To return to privileged EXEC mode,
use the end command.
target bps Sets the target average rate in bits per second (bps). The range is
from 1000 to 1000000000.
percent value Sets the percentage of interface bandwidth. The range is 0 to 100
percent. The percentage is calculated based on the peak information
rate (PIR) of the parent class. If there is no configured PIR at any
level, this is the percentage of the interface speed. Setting the
percent to 0 disables shaping.
