policy-map

This command creates a policy map that can be attached to multiple interfaces, and
enters Policy Map configuration mode. Use the no form to delete a policy map and
return to Global configuration mode.
Syntax
[no] policy-map policy-map-name
policy-map-name - Name of the policy map. (Range: 1-16 characters)
Default Setting
None
Command Mode
Global Configuration
Command Usage
• Use the policy-map command to specify the name of the policy map, and
then use the class command to configure policies for traffic that matches
criteria defined in a class map.
• A policy map can contain multiple class statements that can be applied to the
same interface with the service-policy command (page 4-264).
• You must create a Class Map (page 4-261) before assigning it to a Policy Map.
Example
This example creates a policy called “rd_policy,” uses the class command to specify
the previously defined “rd_class,” uses the set command to classify the service that
incoming packets will receive, and then uses the police command to limit the
average bandwidth to 100,000 Kbps, the burst rate to 1522 bytes, and configure the
response to drop any violating packets.
