Configuring Shaping
The Cisco MWR 2941 supports class-based traffic shaping.
Class-based traffic shaping is configured using a hierarchical policy map structure; you enable traffic
shaping on a primary level (parent) policy map and other QoS features such as queuing and policing on
a secondary level (child) policy map.
The following sections describe how to configure shaping:
• Configuring Class-Based Traffic Shaping in a Primary-Level (Parent) Policy Map
• Configuring the Secondary-Level (Child) Policy Map
Configuring Class-Based Traffic Shaping in a Primary-Level (Parent) Policy Map
Follow these steps to configure a parent policy map for traffic shaping.
Step 9
Router(config-pmap)# exit
Router(config)#
Exits the policy map configuration.
Step 10
Router(config)# interface atm0/ima0
Enters configuration for the interface to which you want to apply the
policy map.
Step 11
Router(config-if)# service-policy
output policy1
Applies the service policy to the interface.
