Preface

Audience

This guide is for the networking professional using the Cisco IOS command-line interface (CLI) to manage the Catalyst 3550 switch, hereafter referred to as the switch or the multilayer switch. Before using this guide, you should have experience working with the Cisco IOS and the switch software features. 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

The Catalyst 3550 switch is supported by either the IP base image (formerly known as the standard multilayer image [SMI]) or the IP services image (formerly known as the enhanced multilayer image [EMI]). The IP services image provides a richer set of enterprise-class features, including hardware-based IP unicast and multicast routing, inter-VLAN routing, routed access control lists (ACLs), and the Hot Standby Router Protocol (HSRP). All Catalyst 3550 Gigabit Ethernet switches are shipped with the IP services image pre-installed. Catalyst 3550 Fast Ethernet switches are shipped with either the IP base image or the IP services image pre-installed. After initial deployment, you can order the upgrade kit to upgrade Catalyst 3550 Fast Ethernet switches from the IP base image to the IP services image.

This guide provides the information you need about the Layer 2 and Layer 3 commands that have been created or changed for use with the Catalyst 3550 family of switches. For information about the standard Cisco IOS Release 12.2 commands, see the Cisco IOS documentation set available from the Cisco.com home page by selecting Service and Support > Technical Documents. On the Cisco Product Documentation home page, select Release 12.2 from the Cisco IOS Software drop-down list.

This guide does not provide procedures for configuring your switch. For detailed configuration procedures, see the Catalyst 3550 Multilayer Switch Software Configuration Guide for this release.

This guide does not describe system messages you might encounter. For more information, see the Catalyst 3550 Multilayer Switch System Message Guide for this release.

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