Chapter 44 Configuring Quality of Service
Configuring VSS QoS
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 disable DBL on the associated queue, use the no dbl policy-map class configuration command.
The following example shows how to configure class-level, DBL action along with average-rate shaping.
It enables DBL on the queue associated with traffic-class class1.
Switch# configure terminal
Switch(config)# policy-map policy1
Switch(config-pmap)# class class1
Switch(config-pmap-c)# shape average 256000
Switch(config-pmap-c)# dbl
Switch(config-pmap-c)# exit
Switch(config-pmap)# exit
Switch(config)# interface gigabitethernet1/1
Switch(config-if)# service-policy output policy1
Switch(config-if)# end
Switch#
Switch# show policy-map policy1

Transmit Queue Statistics
Transmit queue statistics are visible by entering the show policy-map interface command:
Switch# show policy-map interface gigabitEthernet 1/1
GigabitEthernet1/1
Service-policy output: queuing-policy
Class-map: queuing-class (match-all)
