Audience

This guide is for the networking professional managing the Catalyst 2940 switch, hereafter referred to as the switch. Before using this guide, you should have experience working with the Cisco IOS and be familiar with the concepts and terminology of Ethernet and local area networking.

Purpose

This guide provides the information you need to configure software features on your switch.

Use this guide with other documents for information about these topics:

•Requirements—This guide assumes that you have met the hardware and software requirements and cluster compatibility requirements described in the release notes.

•Start-up information—This guide assumes that you have assigned switch IP information and passwords by using the browser setup program described in the switch hardware installation guide.

•Embedded device manager and Network Assistant graphical user interfaces (GUIs)—This guide does not provide detailed information on the GUIs. However, the concepts in this guide are applicable to the GUI user. For information about the device manager, see the switch online help. For information about Network Assistant, see the Getting Started with Cisco Network Assistant, available on Cisco.com.

•Cluster configuration—For information about planning for, creating, and maintaining switch clusters, see the Getting Started with Cisco Network Assistant, available on Cisco.com. For information about the clustering-related command-line interface (CLI) commands, see the command reference for this release.

•CLI command information—This guide provides an overview for using the CLI. For complete syntax and usage information about the commands that have been specifically created or changed for the switches, see the command reference for this release.

This guide provides procedures for using the commands that have been created or changed for use with the switch. It does not provide detailed information about these commands. For detailed information about these commands, see the command reference for this release.

This guide does not repeat the concepts and CLI procedures provided in the standard Cisco IOS Release 12.1 documentation. For information about the standard Cisco IOS Release 12.1 commands, see the Cisco IOS documentation set available from the Cisco.com home page at Service and Support > Technical Documents. On the Cisco Product Documentation home page, select Release 12.1 from the Cisco IOS Software drop-down list.

This guide does not describe system messages you might encounter or how to install your switch. For this information, see the system message guide for this release and to the hardware installation guide.

For documentation updates, see the release notes for this release.
