Commands
● rate police — specifies traffic policing on the selected interface.
● qos-policy-input — creates a QoS output policy.
rate-shape
Shape traffic output as part of the designated policy.
Syntax
rate-shape [kbps | pps] peak-rate [burst-kbps | burst-packets] commited
[kbps | pps] commited-rate [burst-kbps | burst-packets]
Parameters
pps Enter the keyword pps to specify the rate limit in packets per second (pps).
kbps Enter the keyword kbps to specify the rate limit in Kilobits per second (Kbps).
Make the following value a multiple of 64. The range is from 0 to 40000000. The
default granularity is Megabits per second (Mbps).
burst-kbps (OPTIONAL) Enter the burst size in KB. The range is from 0 to 40000. The default
is 100.
burst-packets Enter the peak rate or committed rate burst size in packets per seconds.
Defaults Burst size is 10KB. Granularity for rate is Mbps unless you use the kbps option.

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
