Examples This example shows how to limit the specified traffic class to a data transmission rate of 256 kbps:
Switch(config)# policy-map policy1
Switch(config-pmap)# class class1
Switch(config-pmap-c)# shape average 256000
Switch(config-pmap-c)# exit
Switch(config-pmap)# exit
Switch(config)# interface gigabitethernet1/1/1
Switch(config-if)# service-policy output policy1
You can verify your settings by entering the show policy-map privileged EXEC command.

Shaping restricts the bandwidth available to VLAN-level classes. The shaping rate configured in the
physical-level policy map becomes the total bandwidth available to all VLAN-level classes.
For VLAN-level and class-level classes, the shaping rate becomes the available bandwidth if the
bandwidth is not specified for that class.
For VLAN-level and class-level classes, the shaping rate must be greater or equal to the bandwidth
allocated at that level.
The total bandwidth for VLAN-level classes, including the class-default, cannot exceed the
available bandwidth of the port.
The total bandwidth for class-level classes, including the class-default, cannot exceed the available
bandwidth at the parent VLAN level.
At the VLAN level and at the class level, the configured bandwidth is summed for all the children.
If the summed bandwidth is less than the available bandwidth for the parent, the remaining
bandwidth is distributed equally among the children.
Description
Specifies or modifies the minimum bandwidth provided to a class
belonging to a policy map attached to an ES port.
Specifies the name of the class whose traffic policy you want to create or
change.
Creates or modifies a policy map that can be attached to multiple ports to
specify a service policy.
Enables the strict-priority queue and gives priority to a class of traffic
belonging to a policy map attached to an ES port.
Configures the maximum threshold for tail drop in a policy map attached
to an ES port.
Configures Weighted Random Early Detection (WRED) in a policy map
attached to an ES port.
Creates a service policy as a quality of service (QoS) policy within a
policy map.
Displays QoS policy maps.
