To delete an existing policy map, use the no policy-map policy-map-name global configuration
command. To delete an existing class map, use the no class class-map-name policy-map configuration
command. To return to the default trust state, use the no trust [cos | dscp | ip-precedence] policy-map
configuration command. To remove an assigned DSCP or IP precedence value, use the no set {ip dscp
new-dscp | ip precedence new-precedence} policy-map configuration command. To remove an existing
policer, use the no police rate-bps burst-byte [exceed-action {drop | policed-dscp-transmit}]
policy-map configuration command. To remove the policy map and interface association, use the no
service-policy {input policy-map-name | output policy-map-name} interface configuration command.

Purpose
Define a policer for the classified traffic.
You can configure up to 128 policers on ingress Gigabit-capable
Ethernet ports, up to 8 policers on ingress 10/100 Ethernet ports, and
up to 8 policers on egress ports.
• For rate-bps, specify average traffic rate in bits per second (bps).
The range is 8000 to 2000000000.
For burst-byte, specify the normal burst size in bytes. The range is
•
8000 to 512000000.
(Optional) Specify the action to take when the rates are exceeded.
•
Use the exceed-action drop keywords to drop the packet. Use the
exceed-action policed-dscp-transmit keywords to mark down the
DSCP value (by using the policed-DSCP map) and send the packet.
For more information, see the
Map" section on page
Return to policy map configuration mode.
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.
Note Policy maps that contain set or trust policy-map class
configuration commands or that have ACL classification
cannot be attached to an output interface.
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save your entries in the configuration file.
