Preface

This guide is for the networking professional using the Cisco IOS command-line interface (CLI) to

manage the Catalyst 3750 switch, hereafter referred to as the switch. Before using this guide, you should

have experience working with the Cisco IOS commands and the switch software features. Before using

this guide, you should have experience working with the concepts and terminology of Ethernet and local

area networking.

The Catalyst 3750 switch is supported by either the standard multilayer image (SMI) or the enhanced

multilayer image (EMI). The SMI provides Layer 2+ features including access control lists (ACLs),

quality of service (QoS), static routing, and the Routing Information Protocol (RIP). The EMI provides

a richer set of enterprise-class features. It includes Layer 2+ features and full Layer 3 routing (IP unicast

routing, IP multicast routing, and fallback bridging). To distinguish it from the Layer 2+ static routing

and RIP, the EMI includes protocols such as the Enhanced Interior Gateway Routing Protocol (EIGRP)

and Open Shortest Path First (OSPF) Protocol.

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 3750 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 software configuration guide for this release.

This guide does not describe system messages you might encounter. For more information, see the

system message guide for this release.
