Getting started
About this guide
This guide describes how to install and set up the Virtualized 7750 SR and 7950 XRS Simulator (vSIM).
This guide is organized into functional chapters and includes:
a functional overview of the vSIM
a description of the vSIM system architecture
requirements for the NFV infrastructure (NFVI) supporting the vSIM system
initial commissioning procedures to bring up a vSIM for first-time use
Command outputs shown in this guide are examples only; actual outputs may differ depending on supported functionality and user configuration.
Audience
This guide is intended for anyone who is creating vSIMs 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 XML syntax
7750 SR and 7950 XRS chassis components
SR OS CLI
networking principles and configurations, including virtualized I/O techniques
List of technical publications
After the installation process of the vSIM is completed, see the SR OS documents, as listed in the 7450 ESS, 7750 SR, and 7950 XRS Guide to Documentation , part number 3HE 17144 AAAx TQZZA. These documents contain information about the software configuration and the command line interface (CLI) that is used to configure network parameters and services.
Conventions
This section describes the general conventions used in this guide.
Precautionary and information messages
The following information symbols are used in the documentation.
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
- User must perform this step.
- 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
- User must perform this step.
- User must perform all substeps to complete this action.
- This is one substep.
- This is another substep.
vSIM installation and setup process
This guide is presented in an overall logical configuration flow. Each section describes the tasks for a functional area.
