the router on a specific interface. In the example, the two class maps named class-default and Gold define
the criteria the router uses to classify traffic. The bottom-level child policy map named Business defines
the policing actions for traffic classified as Gold; the top-level parent policy map named All_Traffic
defines the policing actions for default traffic. The Business policy map is applied to the All_Traffic
policy, creating a two-level hierarchical input policing policy.
Example 13-7 Policing Inbound Traffic at Two Levels of Hierarchy
Router(config)# class-map class-default
Router(config-cmap)# match any
Router(config-cmap)# class-map Gold
Router(config-cmap)# match ip precedence 3

Router(config-pmap)# class Gold

Attaching Hierarchical Policies to Physical and Virtual Links

To attach hierarchical policies to interfaces, subinterfaces, virtual circuits, and virtual LANs, enter the
following command:
Command
service-policy {input | output} policy-map-name
OL-7433-09
shows how to configure a hierarchical input policing policy to police the traffic that enters
Purpose
Attaches the policy map you specify.
input indicates to apply the QoS policy to inbound packets. You
must specify the input keyword for hierarchical input policing
policies.
output indicates to apply the QoS policy to outbound packets. You
must specify the output keyword for nested policies and
three-level hierarchical policies.
policy-map-name is the name of a previously configured top-level
parent policy map.
