Version Description
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.
layer2 (OPTIONAL) Enter the keyword layer2 to specify a Layer 2 Class Map. The
default is Layer 3.
