How This Guide is Organized

This guide includes detailed information on the switch software, including how to operate and use the management functions of the switch. To deploy this switch effectively and ensure trouble-free operation, you should first read the relevant sections in this guide so that you are familiar with all of its software features.

This guide is for network administrators who are responsible for operating and maintaining network equipment. The guide assumes a basic working knowledge of LANs (Local Area Networks), the Internet Protocol (IP), and Simple Network Management Protocol (SNMP).

This guide describes the switch’s command line interface (CLI). For more detailed information on the switch’s key features or information about the web browser management interface refer to the Web Management Guide.

The guide includes these sections:

Section I “Getting Started” — Includes information on initial configuration.

Section II “Command Line Interface” — Includes all management options available through the CLI.

Section III “Appendices” — Includes information on troubleshooting switch management access.

Related This guide focuses on switch software configuration through the CLI.
