Usage Information On 40-port 10G stack-unit if the trac is shaped between 64 and 1000 Kbs, for some values, the shaped rate is
much less than the value congured.You must congure the peak rate and peak burst size using the same value:
kilobits or packets per second. Similarly, you must congure the committed rate and committed burst size with the
same measurement. Peak rate refers to the maximum rate for trac arriving or exiting an interface under normal
trac conditions. Peak burst size indicates the maximum size of unused peak bandwidth that is aggregated. This
aggregated bandwidth enables brief durations of burst trac that exceeds the peak rate and committed burst.
Committed rate refers to the guaranteed bandwidth for trac entering or leaving the interface under normal
network conditions. When trac 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 trac falls below the committed rate, the
bandwidth, which is not used by any trac that is traversing the network, is aggregated to form the committed
burst size. Trac is considered to be green-colored up to the point at which the unused bandwidth does not
exceed the committed burst size.
