Usage Information On 40-port 10G stack-unit if the traffic is shaped between 64 and 1000 Kbs, for some

values, the shaped rate is much less than the value configured.You must configure the

peak rate and peak burst size using the same value: kilobits or packets per second.

Similarly, you must configure the committed rate and committed burst size with the

same measurement. Peak rate refers to the maximum rate for traffic arriving or exiting

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 and committed burst.

Committed rate refers to the guaranteed bandwidth for traffic entering or leaving the

interface under normal network conditions. When traffic propagates at an average rate

that is less than or equal to the committed rate, it is considered to be green-colored or

coded. When the transmitted traffic falls below the committed rate, the bandwidth,

which is not used by any traffic that is traversing the network, is aggregated to form the

committed burst size. Traffic is considered to be green-colored up to the point at

which the unused bandwidth does not exceed the committed burst size.

Commands

• rate shape — shapes traffic output as part of the designated policy.

• qos-policy-output — creates a QoS output policy.
