Audience

This guide is for the networking professional managing the Catalyst 3550, 2955, 2950, and 2940 switches, hereafter referred to as the switch. Before using this guide, you should have experience working with the Cisco IOS and the switch software features.

Purpose

This guide describes only the Catalyst 3550, 2955, 2950, and 2940-specific system messages that you might encounter. For a complete list of Cisco IOS system error messages, see the Cisco IOS Software System Error Messages, Cisco IOS Release 12.1.

This guide does not describe how to install your switch or how to configure software features on your switch. It also does not provide detailed information about commands that have been created or changed for use by the switch.

For software information, see the software configuration guide and the command reference for this release.

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