Configuring QoS
Configuring QoS
After you have created an input policy map, you attach it to an interface in the input direction. See Attaching a Traffic
Policy to an Interface, page 609 .
Use the no form of the appropriate command to delete an existing policy map, class map, or policer.
This example shows how to configure 2-rate, 3-color policing using policy-map configuration mode.
Switch(config)#
class-map cos-4
Switch(config-cmap)# match cos 4
Switch(config-cmap)# exit
Switch(config)#
policy-map in-policy
Switch(config-pmap)# class cos-4
Switch(config-pmap-c)# police cir 5000000 pir 8000000 conform-action transmit exceed-action
set-dscp-transmit 24 violate-action drop
Switch(config-pmap-c)# exit
Switch(config-pmap)# exit
Switch(config)#
interface fastethernet0/1
Switch(config-if)# service-policy input in-policy
Switch(config-if)# exit
This example shows how to create the same configuration using policy-map class police configuration mode.
Switch(config)#
class-map cos-4
Switch(config-cmap)# match cos 4
Switch(config-cmap)# exit
Switch(config)#
policy-map in-policy
Switch(config-pmap)# class cos-4
Switch(config-pmap-c)# police cir 5000000 pir 8000000
Switch(config-pmap-c-police)#
conform-action transmit
Switch(config-pmap-c-police)# exceed-action set-dscp-transmit 24
Switch(config-pmap-c-police)# violate-action drop
Switch(config-pmap-c-police)#
end
This example shows how to create a traffic classification with a CoS value of 4, create a policy map, and attach it to an
ingress port. The average traffic rate is limited to 10000000 b/s with a burst size of 10000 bytes:
Switch(config)# class-map video-class
Switch(config-cmap)# match cos 4
Switch(config-cmap)# exit
Switch(config)# policy-map video-policy
Switch(config-pmap)# class video-class
Switch(config-pmap-c)# police 10000000 10000
Switch(config-pmap-c)# exit
Switch(config-pmap)# exit
Switch(config)# interface fastethernet0/1
Switch(config-if)# service-policy input video-policy
Switch(config-if)# exit
This example shows how to create policy map with a conform action of set dscp and a default exceed action.
Switch(config)# class-map in-class-1
Switch(config-cmap)# match dscp 14
Switch(config-cmap)# exit
Switch(config)# policy-map in-policy
Switch(config-pmap)# class in-class-1
10. end Return to privileged EXEC mode.
11. show policy-map [ policy-map-name|
interface ]
Verify your entries.
12. copy running-config startup-config (Optional) Save your entries in the configuration file.
