Preface

About This Guide

This guide describes Quality of Service (QoS) provided by the 7210 SAS-D, E,

and K platforms and presents examples to configure and implement various tests

and presents examples to configure and implement various protocols and services.

On 7210 SAS devices, not all the CLI commands are supported on all the

platforms and in all the modes. In many cases, the CLI commands are mentioned

explicitly in this document. In other cases, it is implied and easy to know the CLIs

that are not supported on a particular platform.

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.

Audience

This manual is intended for network administrators who are responsible for

configuring the 7210 SAS-Series routers. It is assumed that the network

administrators have an understanding of networking principles and

configurations. Protocols, standards, and services described in this manual include

the following:

• CLI concepts

• Quality of Service (QoS) policies and profiles

QoS Overview

The 7210 SAS devices are designed with QoS mechanisms on both ingress and egress to support

multiple services per physical port. The 7210 SAS devices are extensive and flexible capabilities

to Classify, Police, Queue, Shape, and mark traffic.

NOTE: The QoS capabilities supported on different 7210 SAS platforms are different. In other

words, not all the platforms support all of the capabilities. Please read through the following

chapters to know what is available on different 7210 SAS platforms.

In the Alcatel-Lucent service router’s service model, a service is provisioned on the provider-edge

(PE) equipment. Service data is encapsulated and then sent in a service tunnel to the far-end

Alcatel-Lucent service router where the service data is delivered.

The operational theory of a service tunnel is that the encapsulation of the data between the two

Alcatel Lucent service routers appear like a Layer 2 path to the service data although it is really

traversing an IP or IP/MPLS core. The tunnel from one edge device to the other edge device is

provisioned with an encapsulation and the services are mapped to the tunnel that most

appropriately supports the service needs.

The 7210 SAS supports eight forwarding classes internally named: Network-Control, High-1,

Expedited, High-2, Low-1, Assured, Low-2 and Best-Effort. The forwarding classes are discussed

in more detail in Forwarding Classes on page 108.

7210 SAS devices use QoS policies to control how QoS is handled at distinct points in the service

delivery model within the device. There are different types of QoS policies that cater to the

different QoS needs at each point in the service delivery model. QoS policies are defined in a

global context in the 7210 SAS and only take effect when the policy is applied to a relevant entity.

QoS policies are uniquely identified with a policy ID number or name. Typically, Policy ID 1 or

Policy ID “default” (there are a few instances where the default QoS policy uses a different ID) is

reserved for the default policy which is used if no policy is explicitly applied.

The QoS policies within the 7210 SAS can be divided into three main types:

• QoS policies are used for classification, defining metering and queuing attributes and

defining marking behavior.

• Slope policies define default buffer allocations and WRED slope definitions.

• Port Scheduler policies, SAP ingress/egress policies or network/network-queue policies

determine how queues are scheduled.
