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 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 base image provides Layer 2+ features including access control lists (ACLs), quality of

service (QoS), static routing, and the Routing Information Protocol (RIP). The IP services image

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 IP services image includes protocols such as the Enhanced Interior Gateway

Routing Protocol (EIGRP) and Open Shortest Path First (OSPF) Protocol.

This guide provides the information that 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 Technical Support & Documentation > Cisco IOS Software.

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.
