Syntax Description
Defaults No policy maps are defined.
The default behavior is to set the Differentiated Services Code Point (DSCP) to 0 if the packet is an IP
packet and to set the class of service (CoS) to 0 if the packet is tagged. No policing is performed.
Command Modes Global configuration
Command History
Usage Guidelines Entering the policy-map command enables the policy-map configuration mode. These configuration
commands are available:
• class: defines the classification match criteria for the specified class map. For more information, see
the
“class” section on page 2-38.
• description: describes the policy map (up to 200 characters).
• exit: exits policy-map configuration mode and returns you to global configuration mode.
• no: removes a previously defined policy map.
• rename: renames the current policy map.
To return to global configuration mode, use the exit command. To return to privileged EXEC mode, use
the end command.
Before you can configure policies for classes whose match criteria are defined in a class map, use the
policy-map command to specify the name of the policy map to be created, added to, or modified.
Entering the policy-map command also enables the policy-map configuration mode in which you can
configure or modify the class policies for that policy map.
You can configure class policies in a policy map only if the classes have match criteria defined for them.
You use the class-map global configuration and match class-map configuration commands to configure
the match criteria for a class. You define packet classification on a physical-port basis and on a per-port
per-VLAN basis.
policy-map-name Name of the policy map.
