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.7450 ESS, 7750 SR, 7950 XRS, and VSR Classic CLI Command Reference Guide.

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.

  1. 7750 SR-a4/a8
  2. 7750 SR-1e/2e/3e
  3. 7750 SR-12e
  4. 7750 SR-1
  5. 7750 SR-7/12
  6. 7750 SR-1s/2s
  7. 7750 SR-7s/14s
  1. 7950 XRS-16c
  2. 7950 XRS-20/40
  3. 7950 XRS-20e

For a list of unsupported features by platform and chassis, refer to the SR OS 21.x.Rx Software Release Notes, part number 3HE 17177 000x TQZZA.

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

Note:

The SR OS CLI trees and command descriptions can be found in the following guides:

  1. 7450 ESS, 7750 SR, 7950 XRS, and VSR Classic CLI Command Reference Guide
  2. 7450 ESS, 7750 SR, 7950 XRS, and VSR Clear, Show, and Tools Command Reference Guide (for both MD-CLI and Classic CLI)
  3. 7450 ESS, 7750 SR, 7950 XRS, and VSR MD-CLI Command Reference Guide
Note:

This guide generically covers Release 21.x.Rx content and may contain some content that will be released in later maintenance loads. Refer to the SR OS 21.x.Rx Software Release Notes, part number 3HE 17177 000x TQZZA, for information about features supported in each load of the Release 21.x.Rx software.

1.2. Router Configuration Process

Table 2 lists the tasks necessary to configure system security and access functions and logging features on the 7450 ESS, 7750 SR, and 7950 XRS platforms. 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.

Note:

All features are supported on all SR OS platforms (7750 SR, 7450 ESS, and 7950 XRS) unless indicated otherwise.

1.3. Node Management Using VPRN

While customarily node management is operated either via the out-of-band interface or in-band via the Base routing instance, it is also possible to manage the node using a VPRN. Both IPv4 and IPv6 are supported.

The following management plane clients are supported using VPRN:

  1. DNS
  2. gRPC (dial-out telemetry)
  3. RADIUS
  4. SNMP (traps)
  5. SSH
  6. Syslog
  7. TACACS+
  8. Telnet

The following servers are supported using VPRN:

  1. FTP
  2. gRPC
  3. NETCONF (including notifications)
  4. SNMP
  5. SSH
  6. Telnet

Refer to section 3.2.16 in the Layer 3 Services Guide for further details.
