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.
Interface rate policing limits the rate of trac that is received on an interface.
Congure Interface rate policing
1 Create a QoS type empty class-map to match all the trac.
OS10(config)# class-map example-cmap-all-traffic
2 Create a QoS type policy-map to dene a policer.
OS10(config)# policy-map example-interface-policer
OS10(config-pmap-qos)# class example-cmap-all-traffic
OS10(config-pmap-c-qos)#police cir 4000 pir 6000
3 Apply the QoS type policy-map to an interface.
OS10(config)# interface ethernet 1/1/14
OS10(conf-if-eth1/1/14)# service-policy input type qos example-interface-policer
Flow rate policing controls the rate of ow of trac.
Congure ow rate policing
1 Create a QoS type class-map to match the trac ow.
OS10(config)# class-map example-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 example-flow-policer
OS10(config-pmap-qos)# class example-cmap-cos3
OS10(config-pmap-c-qos)# set qos-group 3
OS10(config-pmap-c-qos)#police cir 4000 pir 6000
3 Apply the QoS type policy-map to an interface.
OS10(config)# interface ethernet 1/1/15
OS10(conf-if-eth1/1/15)# service-policy input type qos example-flow-policer
Mark Trac
You can select a ow and mark it with a trac class ID. Trac class IDs identify the trac ow 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 it with a trac class ID and assign it to 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
Color trac
You can select a trac ow and mark it with a color. Color the trac ow based on:
• Metering. See Policing trac.
• Default trust. See Trust-based classication.
• DSCP, ECN capable trac (ECT), or non-ECT capable trac.
Color trac based on DSCP, ECT, or non-ECT
