1. Getting Started

1.1. About This Guide

This guide describes system concepts and provides configuration explanations and examples to configure SR OS boot option file (BOF), file system and system management functions. Also provided are concepts and descriptions of the Command Line Interface (CLI) syntax and command usage.

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.

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

  1. 7450 ESS
  2. 7750 SR
  3. 7950 XRS
  4. VSR

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 R16.0.Rx Software Release Notes, part number 3HE 14220 000x TQZZA or the VSR Release Notes, part number 3HE 14204 000x TQZZA.

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


This guide generically covers Release 16.0.Rx content and may contain some content that will be released in later maintenance loads. Refer to the SR OS R16.0.Rx Software Release Notes, part number 3HE 14220 000x TQZZA or the VSR Release Notes, part number 3HE 14204 000x TQZZA, for information about features supported in each load of the Release 16.0.Rx software.

1.2. Router System Configuration Process

Table 2 lists the tasks necessary to configure boot option files (BOF) and system and file management functions. Each chapter in this book 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. After the hardware installation has been properly completed, proceed with the router configuration tasks in the following order:
