Version Description
7.5.1.0 Introduced on the C-Series.
6.1.1.1 Introduced on the E-Series.
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.

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.
