Chapter 33 Configuring QoS
When you use a table map in an input policy map, the protocol type for the from–action in the table map
Note
must be the same as the protocol type of the associated classification. For example, if a class map
represents IP classification, the from–type action in the table map must be either dscp or precedence.
If the class map represents a non-IP classification, the from–type action in the table map must be cos.
You can configure multiple conform and exceed actions simultaneously for an aggregate policer as
parameters in the policer aggregate global configuration command, but you must enter the actions in a
particular order. See the configuration guideline in the
Policing" section on page
After you configure the aggregate policer, you create a policy map and an associated class map, associate
the policy map with the aggregate policer, and apply the service policy to a port.
Note Only one policy map can use any specific aggregate policer. Aggregate policing cannot be used to
aggregate traffic streams across multiple interfaces. It can be used only to aggregate traffic streams
across multiple classes in a policy map attached to an interface and aggregate streams across VLANs on
a port in a per-port, per-VLAN policy map.
After you configure the policy map and policing actions, attach the policy to an ingress port by using the
service-policy interface configuration command.
The class maps in this example refer to access lists.
Switch(config)# policer aggregate agg1 cir 23000 bc 10000 conform-action set-dscp-transmit
46 exceed-action drop
Switch(config)# class-map testclass
Switch(config-cmap)# match access-group 1
Switch(config-cmap)# exit
Switch(config)# class-map videoclass
Switch(config-cmap)# match access-group 2
Switch(config-cmap)# exit
Switch(config)# policy-map testexample
Switch(config-pmap)# class testclass
Switch(config-pmap-c)# police aggregate agg1
Switch(config-pmap-c)# exit
Switch(config-pmap)# class video-class
Switch(config-pmap-c)# police aggregate agg1
Switch(config-pmap-c)# exit
Switch(config-pmap)# exit
Switch(config)# interface fastethernet0/1
Switch(config-if)# service-policy input testexample
Switch(config-if)# exit
For configuration information, see the
on page
If the switch is running the metro IP access or metro access image, you can also use aggregate policing
to regulate traffic streams across VLANs, as in this example:
Switch(config)# policer aggregate agg1 cir 23000 bc 10000 conform-action set-dscp-transmit
af31 set-cos-transmit 3 exceed-action set-dscp-transmit af11 set-cos-transmit 1
Switch(config)# class-map video-provider-1
Switch(config-cmap)# match access-group 1
Switch(config-cmap)# exit
Switch(config)# class-map video-provider-2
Switch(config-cmap)# match access-group 2
Switch(config-cmap)# exit
Switch(config)# class-map match-any customer1-provider-100
