1.1. About This Guide

This guide describes the Quality of Service (QoS) provided by the routers and presents examples to configure and implement various protocols and services.

This document is organized into functional chapters and provides concepts and descriptions of the implementation flow, as well as Command Line Interface (CLI) syntax and command usage.

The topics and commands described in this document apply to the:

Table 1 lists the available chassis types for each SR OS router.

For a list of unsupported features by platform and chassis, refer to the SR OS 20.x.Rx Software Release Notes, part number 3HE 16194 000x TQZZA.

Command outputs shown in this guide are examples only; actual displays may differ depending on supported functionality and user configuration.

Note: This guide generically covers Release 20.x.Rx content and may contain some content that will be released in later maintenance loads. Refer to the SR OS 20.x.Rx Software Release Notes, part number 3HE 16194 000x TQZZA for information about features supported in each load of the Release 20.x.Rx software.

1.2. QoS Configuration Process

Table 2 lists the tasks necessary to configure and apply QoS policies. This guide is presented in an overall logical configuration flow. Each section describes a software area and provides CLI syntax and command usage to configure parameters for a functional area.
