Chapter 37 Configuring Quality of Service
Configuring QoS on Supervisor Engine 6-E, Supervisor Engine 6L-E, Catalyst 4900M, and Catalyst 4948E
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 the average-rate traffic shaping, use the no shape average policy-map class configuration
command.
This example shows how to configure class level, average-rate shaping. It limits traffic class class1 to a
data transmission rate of 256 kbps:
Switch# configure terminal
Switch(config)# policy-map policy1
Switch(config-pmap)# class class1
Switch(config-pmap-c)# shape average 256000
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
Policy Map policy1
Class class1
shape average 256000
This example shows how to configure class level, average shape percentage to 32 percent of link
bandwidth for queuing-class traffic:
Switch# configure terminal
Switch(config)# policy-map queuing-policy
Switch(config-pmap)# class queuing-class
Switch(config-pmap-c)# shape average percent 32
Switch(config-pmap-c)# exit
Switch(config-pmap)# exit
Switch(config)# interface gigabitethernet1/1
Switch(config-if)# service-policy output queuing-policy1
Switch(config-if)# end
Switch #
Switch# show policy-map queuing-policy
