Configuration Example for Configuring CBWFQ and Attaching a Policy to an
ATM Subinterface
Example 12-6 shows how to configure CBWFQ in a policy map and attach the policy to an ATM
subinterface. This example creates a class map named voice to classify traffic and assigns class
characteristics in the policy map named policy1. The service policy is applied to the ATM
subinterface
7/0/0.1, which uses PPPoA encapsulation.
Example 12-6 Configuring CBWFQ and Attaching a Policy to a PPPoA Subinterface
Router(config)# class-map voice
Router(config-cmap)# match any
Router(config-cmap)# exit
Router(config)# policy-map policy1
Router(config-pmap)# class voice
Router(config-pmap-c)# police 120000 16000 32000 conform-action transmit exceed-action
set-prec-transmit 4
Router(config-pmap-c)# exit
Router(config-pmap)# exit
Router(config)# interface atm7/0/0.1 point-to-point
Router(config-subif)# pvc 10/32
Router(config-subif-atm-pvc)# encapsulation aal5mux ppp virtual-template 1
Router(config-subif-atm-pvc)# service-policy output policy1
Router(config-subif)# interface virtual-template 1
Router(config-if)# ip unnumbered loopback1
Router(config-if)# peer default ip address pool pool1
Router(config-if)# ppp authentication chap
Configuration Example for Configuring CBWFQ and Attaching a Policy to an
RBE Subinterface
Example 12-7 shows how to configure CBWFQ in a policy map and attach the policy to an routed bridge
encapsulation (RBE) subinterface. The example creates a class map named voice and a policy map
named map1. The service policy is applied to the ATM subinterface 7/0/1.1, which uses ATM RBE.
Example 12-7 Configuring CBWFQ and Attaching a Policy to an RBE Subinterface
Router(config)# class-map voice
Router(config-cmap)# match all
Router(config-cmap)# exit
Router(config)# policy-map map1
Router(config-pmap)# class voice
Router(config-pmap-c)# police 120000 16000 32000 conform-action transmit exceed-action set
precedence-transmit 4
Router(config-pmap-c)# exit
Router(config-pmap)# exit
Router(config-if)# interface atm7/0/1.1 point-to-point
Router(config-subif)# ip unnumbered loopback1
Router(config-subif)# atm route-bridge ip
Router(config-subif)# service-policy output map1
Router(config-subif)# range pvc 101/32 101/2031
Router(config-subif-atm-pvc)# encapsulation aal5snap
