Example 13-12 Configuring Hierarchical Input Policing
Router(config)# class-map match-any class-default [Defines classification criterion.]
Router(config-cmap)# class-map Click [Defines classification criterion.]
Router(config-cmap)# match ip precedence 2
Router(config-cmap)# exit
Router(config)# policy-map Policy2 [Defines bottom-level child policy.]
Router(config-pmap)# class Click
Router(config-pmap-c)# police 200000 2000 pir 400000 3000 conform-action set-dscp-transmit
59 exceed-action set-dscp-transmit 60 violate-action drop [Configures two-rate policer.]
Router(config-pmap-c)# exit
Router(config-pmap)# policy-map Parentbps1 [Defines top-level parent policy.]
Router(config-pmap)# class class-default
Router(config-pmap-c)# police 128000 2000 pir 256000 4000 conform-action transmit
exceed-action transmit violate-action drop [Configures two-rate three-color policer.]
Router(config-pmap-c)# service-policy Policy2 [Applies bottom-level child to parent.]

Router(config-pmap)# exit
Router(config)# interface atm 1/0/0.10 point-to-point

OL-7433-09
shows how to configure a hierarchical input policing policy to limit the rate of traffic that
Class maps named class-default and Click that define the classification criteria the router uses to
classify packets.
A bottom-level child policy map named Policy2 that defines a two-rate three-color policer for the
Click traffic class.
A top-level parent policy named Parentbps1 that contains the class-default class, which defines a
two-rate three-color policer for default traffic. The bottom-level child policy named Policy2 is
applied to the Parentbps1 class-default class.
The top-level parent policy is attached to PVC 101/102 on the ATM point-to-point
subinterface 1/0/0.10.
