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(config)# class-map class1
Switch(config-cmap)# match cos 0 1 2 3
Switch(config-cmap)# exit
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 gigabitethernet1/1/1
Switch(config-if)# service-policy output policy1
This example shows how to configure VLAN-level, average-rate shaping. It limits each traffic class,
vlan101 and vlan102, to a data transmission rate of 400 Mbps.
Switch(config)# class-map match-all vlan101
Switch(config-cmap)# match vlan 101
Switch(config-cmap)# exit
Switch(config)# class-map match-all vlan102
Switch(config-cmap)# match vlan 102
Switch(config-cmap)# exit
Switch(config)# policy-map vlan-policy
Switch(config-pmap)# class vlan101
Switch(config-pmap-c)# shape average 400000000
Switch(config-pmap-c)# exit
Switch(config-pmap)# class vlan102
Switch(config-pmap-c)# shape average 400000000
Switch(config-pmap-c)# exit
Switch(config-pmap)# exit
Switch(config)# interface gigabitethernet1/1/1
Switch(config-if)# switchport trunk encapsulation isl
Switch(config-if)# switchport mode trunk
Switch(config-if)# service-policy output vlan-policy
