Purpose
Create a policy map by entering the policy map name, and enter
policy-map configuration mode.
For more information, see the
Traffic by Using Policy Maps" section on page
Define a traffic classification, and enter policy-map class configuration
mode.
By default, no policy map class-maps are defined.
If a traffic class has already been defined by using the class-map global
configuration command, specify its name for class-map-name in this
command.
Apply an aggregate policer to multiple classes in the same policy map.
For aggregate-policer-name, enter the name specified in Step 3.
Return to global configuration mode.
Enter interface configuration mode, and specify the interface to attach
to the policy map.
Valid interfaces include physical interfaces.
Apply a policy map to the input or output of a particular interface.
Only one policy map per interface per direction is supported.
Use input policy-map-name to apply the specified policy-map to
•
the input of an interface.
• Use output policy-map-name to apply the specified policy-map to
the output of an interface.
You cannot use the service-policy interface configuration command to
attach policy maps that contain these elements to an egress interface:
• set or trust policy-map class configuration commands. Instead,
you can use the police policy-map class configuration command to
mark down (reduce) the DSCP value at the egress interface.
• Access control list (ACL) classification.
• Per-port per-VLAN classification.
The only match criterion in a policy map that can be attached to an
egress interface is the match ip dscp dscp-list class-map configuration
command.
Per-port per-VLAN policing is not supported on routed ports or on
virtual (logical) interfaces.
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save your entries in the configuration file.
