Audience

This guide is for the networking professional using the Cisco IOS command-line interface (CLI) to manage the Catalyst 3750-X and 3560-X switch, or the Catalyst 3750-X switch stack, 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.

Purpose

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-X and 3560-X switches.
