1 Create a class-map of type queuing to match queue 5
OS10(config)# class-map type queuing q5
2 Dene the queue to match
OS10(config-cmap-queuing)# match queue 5
Policing trac
Use policing to limit the rate of ingress trac ow. The ow can be all the ingress trac on a port or a particular ow assigned with a trac
class ID.
In addition, you can use policing to color the trac.
• When trac arrives at a rate less than the committed rate, the color is green.
• When trac propagates at an average rate greater than or equal to the committed rate and less than peak-rate, the color is yellow.
• When the trac rate is above the congured peak-rate, the trac is dropped to guarantee a bandwidth limit for an ingress trac ow.
Peak rate is the maximum rate for trac arriving or leaving an interface under normal trac conditions. Peak burst size indicates the
maximum size of unused peak bandwidth that is aggregated. This aggregated bandwidth enables brief durations of burst trac that
exceeds the peak rate.
Congure Interface rate policing
1 Create a QoS type empty class-map to match all the trac
OS10(config)# class-map cmap-all-traffic
2 Create a QoS type policy-map to dene a policer
OS10(config)# policy-map interface-policer
OS10(config-pmap-qos)# class cmap-all-traffic
OS10(config-pmap-c-qos)#police cir 4000 pir 6000
Congure ow rate policing
1 Create a QoS type class-map to match the trac ow
OS10(config)# class-map cmap-cos3
OS10(config-cmap-qos)# match cos 3
2 Create a QoS type policy-map to dene a policer and assign a trac class ID for the CoS ow
OS10(config)# policy-map flow-policer
OS10(config-pmap-qos)# class cmap-cos3
OS10(config-pmap-c-qos)# set qos-group 3
OS10(config-pmap-c-qos)#police cir 4000 pir 6000
Mark Trac
You can select a ow and mark with a trac class ID. The trac ow is identied by the trac class ID when the trac reaches egress for
queue scheduling.
Mark trac
1 Create a QoS type class-map to match the trac ow
OS10(config)# class-map cmap-cos3
OS10(config-cmap-qos)# match cos 3
2 Create a QoS type policy-map to mark with a trac class ID and assign it for the CoS ow.
OS10(config)# policy-map cos3-TC3
OS10(config-pmap-qos)# class cmap-cos3
OS10(config-pmap-c-qos)# set qos-group 3
