Getting started

About this guide

This guide describes how to install, deploy, and setup the Nokia Containerized Service Router Simulator (SR-SIM) for the 7250 IXR, 7450 ESS, 7750 SR, and 7950 XRS router.
Note: Unless otherwise indicated, command line interface (CLI) commands, contexts, and configuration examples in this guide apply for both the MD-CLI and the classic CLI.

This guide is organized into functional chapters and includes:

  • a functional overview of the SR-SIM tool
  • a description of the SR-SIM system architecture
  • requirements for containerization infrastructure supporting the SR-SIM
  • initial commissioning procedures to bring up the SR-SIM in various environments and modelling various hardware platforms

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

Deployment examples provided in this guide assume the Linux host operating system. Commands and outputs may vary on other host operating systems.
Note: This guide generically covers 25.x.Rx content and may contain some content that will be released in later maintenance loads. For information about features supported in each load of the Release 25.x.Rx software or for a list of unsupported features by platform and chassis, see the SR OS R25.x.Rx Software Release Notes, part number 3HE 21562 000x TQZZA.

Audience

This guide is intended for anyone who is creating SR-SIMs in a qualified lab environment. It is assumed that the reader has an understanding of the following:

  • x86 hardware architecture
  • Linux system installation, configuration, and administration methods
  • basic YAML syntax
  • 7250 IXR, 7450 ESS, 7750 SR, and 7950 XRS router chassis components
  • SR OS CLI (Classic and Model-Driven)
  • UNIX/Linux system administration principles
  • networking principles and configurations, including virtualized I/O techniques in a containerized environment

List of technical publications

After the SR-SIM is successfully deployed, see the product-specific Guide to Documentation for a list of applicable SR OS user guides for the 7250 IXR, 7450 ESS, 7750 SR, or 7950 XRS. These guides contain information about the software configuration and CLI that is used to configure network parameters and services on that router.

Conventions

This section describes the general conventions used in this guide.

Precautionary and information messages

The following information symbols are used in the documentation.

DANGER: Danger warns that the described activity or situation may result in serious personal injury or death. An electric shock hazard could exist. Before you begin work on this equipment, be aware of hazards involving electrical circuitry, be familiar with networking environments, and implement accident prevention procedures.
WARNING: Warning indicates that the described activity or situation may, or will, cause equipment damage, serious performance problems, or loss of data.
Caution: Caution indicates that the described activity or situation may reduce your component or system performance.
Note: Note provides additional operational information.
Tip: Tip provides suggestions for use or best practices.

Options or substeps in procedures and sequential workflows

Options in a procedure or a sequential workflow are indicated by a bulleted list. In the following example, at step 1, the user must perform the described action. At step 2, the user must perform one of the listed options to complete the step.

Options in a procedure
  1. User must perform this step.
  2. This step offers three options. User must perform one option to complete this step.
    • This is one option.
    • This is another option.
    • This is yet another option.

Substeps in a procedure or a sequential workflow are indicated by letters. In the following example, at step 1, the user must perform the described action. At step 2, the user must perform two substeps (a. and b.) to complete the step.

Substeps in a procedure
  1. User must perform this step.
  2. User must perform all substeps to complete this action.
    1. This is one substep.
    2. This is another substep.
