Peak rate is the maximum rate for traffic arriving or leaving an interface under normal traffic conditions. Peak burst size indicates the maximum size of unused peak bandwidth that is aggregated. This aggregated bandwidth enables brief durations of burst traffic that exceeds the peak rate.

The traffic flow is identified by the traffic class ID when the traffic reaches egress for queue scheduling. Mark traffic 1 Create a QoS type class-map to match the traffic flow OS10(config)# class-map cmap-cos3 OS10(config-cmap-qos)# match cos 3 2 Create a QoS type policy-map to mark with a traffic class ID and assign it for the CoS flow.

You can color the traffic flow based on: • Metering. See Policing traffic. • Default trust. See Trust based classification. • DSCP , ECN capable traffic (ECT), or non-ECT. Color traffic based on DSCP, ECT, or non-ECT 1 Create a QoS type class-map to match the traffic flow.
