Chapter 33 Configuring QoS
Configuring QoS
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
Switch(config-pmap-c)# police 230000 8000 conform-action set-dscp-transmit 33
exceed-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 use policy-map class police configuration mode to set multiple conform
actions and an exceed action. The policy map sets a committed information rate of 23000 bits per second
(bps) and a conform burst size of 10000 bytes. The policy map includes multiple conform actions (for
DSCP and for Layer 2 CoS) and an exceed action.
Switch(config)# class-map cos-set-1
Switch(config-cmap)# match cos 3
Switch(config-cmap)# exit
Switch(config)# policy-map map1
Switch(config-pmap)# class cos-set-1
Switch(config-pmap-c)# police cir 23000 bc 10000
Switch(config-pmap-c-police)# conform-action set-dscp-transmit 48
Switch(config-pmap-c-police)# conform-action set-cos-transmit 5
Switch(config-pmap-c-police)# exceed-action drop
Switch(config-pmap-c-police)# exit
Switch(config-pmap)# exit
Switch(config)# interface fastethernet0/1
Switch(config-if)# service-policy input map1
Switch(config-if)# exit
This example shows how to use policy-map class police configuration mode to set exceed action
mark-down using table-maps. The policy map sets a committed information rate of 23000 bps and a
conform burst-size of 10000 bytes. The policy map includes the default conform action (transmit) and
the exceed action to mark the Layer 2 CoS value based on the table map and to mark IP DSCP to af41.
Switch(config)# policy-map in-policy
Switch(config-pmap)# class in-class-1
Switch(config-pmap-c)# police cir 23000 bc 10000
Switch(config-pmap-c-police)# exceed-action set-cos-transmit cos table
police-cos-markdn-tablemap
Switch(config-pmap-c-police)# exceed-action set-dscp-transmit af41
