PrefaceAudienceThis guide is for the networking professional using the Cisco IOS command-line interface (CLI) tomanage the Catalyst 3750 switch, hereafter referred to as the switch. Before using this guide, you shouldhave experience working with the Cisco IOS commands and the switch software features. Before usingthis guide, you should have experience working with the concepts and terminology of Ethernet and localarea networking.PurposeThe Catalyst 3750 switch is supported by either the IP base image, formerly known as the standardmultilayer 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 ofservice (QoS), static routing, and the Routing Information Protocol (RIP). The IP services imageprovides 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 GatewayRouting 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 havebeen created or changed for use with the Catalyst 3750 switches. For information about the standard CiscoIOS Release 12.2 commands, see the Cisco IOS documentation set available from the Cisco.com home pageby selecting Technical Support & Documentation Cisco IOS Software.This guide does not provide procedures for configuring your switch. For detailed configurationprocedures, see the software configuration guide for this release.This guide does not describe system messages you might encounter. For more information, see thesystem message guide for this release.For documentation updates, see the release notes for this release.Catalyst 3750 Switch Command ReferenceOL-8552-01xix
