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.
service-policy input
Apply an input policy map to the selected interface.
Syntax
service-policy input policy-map-name [layer2]
To remove the input policy map from the interface, use the no service-policy
input policy-map-name [layer2] command.
Parameters
policy-map-name Enter the name for the policy map in character format (32
characters maximum). You can identify an existing policy
map or name one that does not yet exist.
