Preface

About This Guide

This guide describes system concepts and provides configuration examples to provision input/

output modules (IOMs), also referred to as cards, Media Dependent Adapters (MDAs), and ports.

This guide 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 guide is intended for network administrators who are responsible for configuring the 7750 SR

routers. It is assumed that the network administrators have an understanding of networking

principles and configurations. Concepts described in this guide include the following:

•CLI concepts

• IOM, MDA, and port configuration

• QoS policies

•Services

Table 2 lists the tasks necessary to provision input/output control modules (IOMs), also referred to

as cards, Media Carrier Modules (MCMs), Media Dependent Adapters (MDAs),and ports.

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.

Note: In SR OS any function that displays an IPv6 address or prefix changes to reflect rules

described in RFC 5952, A Recommendation for IPv6 Address Text Representation. Specifically,

hexadecimal letters in IPv6 addresses are now represented in lowercase, and the correct

compression of all leading zeros is displayed. This changes visible display output compared to

previous SR OS releases. Previous SR OS behavior can cause issues with operator scripts that use

standard IPv6 address expressions and with libraries that have standard IPv6 parsing as per RFC

5952 rules. See the section on IPv6 Addresses in the Router Configuration Guide for more

information.
