To delete an existing policy map, use the no policy-map policy-map-name global configuration
command. To delete an existing class, use the no class class-name policy-map configuration command.
To remove the two-rate policer, use the no police cir cir [bc conform-burst] pir pir [be peak-burst]
[conform-action action [exceed-action action [violate-action action]]] policy-map class configuration
command. To remove the policy map and interface association, use the no service-policy output
policy-map-name interface configuration command.
This example shows how to configure a class-level, two-rate traffic policer to limit outbound traffic to
an average committed rate of 500 kbps and a peak rate of 1 Mbps. Traffic marked as conforming to the
average committed rate (500 kbps) is sent as is. Traffic marked as exceeding 500 kbps, but not exceeding
1 Mbps, is marked with IP precedence 2 and then sent. All traffic marked as exceeding 1 Mbps is
dropped. The burst parameters are set to 10000 bytes.

This example shows how to configure a class-level, two-rate traffic policer that uses a CIR and a PIR
based on a percentage of bandwidth. A CIR of 20 percent and a PIR of 40 percent are specified. The
optional bc and be values (300 ms and 400 ms, respectively) are specified.
Switch(config)# class-map c1
Switch(config-cmap)# match ip precedence 4
Switch(config-cmap)# exit

Switch(config-pmap-c)# police cir percent 20 bc 300 ms pir percent 40 be 400 ms

Switch(config-pmap)# exit

Purpose
Return to global configuration mode.
Specify an ES port to attach to the policy map, and enter interface
configuration mode.
Specify the egress policy-map name, and apply it to the ES port.
Only one policy map per port is supported.
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save your entries in the configuration file.
