You can use the rate-shape pps peak-rate burst-packets command in the QoS Policy Out
Configuration mode to configure the peak rate and burst size as a measure of pps. Alternatively, you can
use the rate shape kbps peak-rate burst-KB command to configure the peak rate and peak burst
size as a measure of bytes.
Similarly, you can use the rate-shape pps peak-rate burst-packets committed pps
committed-rate burst-packets command in the QoS Policy Out Configuration mode to configure
the committed rate and committed burst size as a measure of pps. Alternatively, you can use the
rate
shape kbps peak-rate burst-KB committed kbps committed-rate burst-KB command to
configure the committed rate and committed burst size as a measure of bytes. If you configure the peak
rate in pps, the peak burst size must also be configured as a measure of number of packets. Similarly, if
you configure the peak rate in Kbps, the peak burst size must also be configured as a measure of bytes.
Configuring Policy-Based Rate Shaping
Configuration of rate shaping for QoS output policies in packets per second (pps) is supported on the
platform.
You can explicitly specify the rate shaping functionality for QoS output policies as peak rate and
committed rate attributes. You can also configure the peak burst and committed burst sizes. All of these
settings can be configured in Kbps, Mbps, or pps.
To configure the peak and committed rates and burst sizes, perform the following steps:
1. Configure the peak rate and peak burst size in pps in QoS Policy Out Configuration mode.
QOS-POLICY-OUT mode
Dell(config-qos-policy-out)# rate shape pps peak-rate burst-packets
2. Alternatively, configure the peak rate and peak burst size in bytes.
QOS-POLICY-OUT mode
Dell(config-qos-policy-out)# rate shape Kbps peak-rate burst-KB
3. Configure the committed rate and committed burst size in pps.
QOS-POLICY-OUT mode
Dell(config-qos-policy-out)# rate shape pps peak-rate burst-packets
committed pps committed-rate burst-packets
4. Alternatively, configure the committed rate and committed burst size in bytes.
QOS-POLICY-OUT mode
Dell(config-qos-policy-out)# rate shape Kbps peak-rate burst-KB committed
Kbps committed-rate burst-KB
Configuring Weights and ECN for WRED
The WRED congestion avoidance functionality drops packets to prevent buffering resources from being
consumed. Traffic is a mixture of various kinds of packets. The rate at which some types of packets arrive
