Setup Guide

Packets (OPTIONAL) Enter the peak burst size as a count of packets. The range is from
1 to 1073000. The default is 50 packets. The default peak rate is regarded as the
same value as the configured peak rate.
Default Granularity for rate is Mbps unless you use the kbps option.

Version Description
9.10(0.1) Introduced on the S6010-ON and S4048T-ON.
9.10(0.0) Introduced on the S6100-ON.
9.8(1.0) Introduced on the Z9100-ON.
9.7(0.0) Introduced on the S6000-ON.
9.3(0.0) Added support for committed rate and committed burst size, and for configuration
of rate limits on the S6000 platform.
Usage
Information
If you specify the pps keyword after the rate-shape command, the peak rate, peak burst, committed
rate and committed burst are all considered to be values as a measure of packets. If you do not specify
the pps or kbps keyword, the peak and committed rate settings are considered to be values in Mbps.
Similarly, if you enter the kbps keyword, the peak and committed rate settings are treated as values in
Kbps.
You cannot configure the committed rate settings to use a different metric or unit from the metric that
is set for peak rate attributes because when you use the rate-shape kbps command, it denotes the
metric for peak and committed rate attributes). Similarly, if you use the rate-shape pps option , it
denotes the metric for peak rate and committed rate attributes.
If you attempt to define the committed rate to be less than the peak rate, an error message is displayed
stating that the peak rate cannot be lower than the committed rate. You can configure all the rate
shaping parameters to be either in bytes or packets measure for each queue. The rate and burst
parameters for both minimum and maximum settings for a queue can be either in packets or bytes. You
cannot configure some of rate shaping attributes to be in bytes measure and the remaining rate shaping
attributes to be in packets measure; all the rate shaping attributes must contain the same metric or unit
of measure.
Example
DellEMC(conf-qos-policy-out) #rate-shape pps 100 100 peak pps 1000 200
DellEMC(conf-qos-policy-out) #rate-shape kbps 1024 100 peak kbps 102400
75
DellEMC(conf-qos-policy-out) # rate-shape 100 100 peak 1000 750
DellEMC(conf-qos-policy-in)#rate-police 100 25 peak 80 500
% Error: Peak rate cannot be less than committed rate.
service-pool wred
A global buffer pool that is a shared buffer pool accessed by multiple queues when the minimum guaranteed buffers for the
queue are consumed can be configured on the S6000 and Z9000 platforms.
Create a global buffer pool that is a shared buffer pool accessed by multiple queues when the minimum guaranteed buffers for
the queue are consumed. S4810, S4820T, S6000, and Z9000 platforms support four global service-pools in the egress direction.
Two service pools are used—one for lossy queues and the other for lossless (priority-based flow control (PFC)) queues. You
can enable WRED and ECN configuration on the global service-pools. You can define WRED profiles and weight on each of the
global service-pools for both lossy and lossless (PFC) service-pools.
Syntax
[No] service-pool wred {green | weight | yellow} pool0 number/string
Parameters
service-pool Define the mapping between the service class and policy-based QoS or routing.
