Preface
Audience
This guide is for the networking professional using the Cisco IOS command-line interface (CLI) to
manage the Catalyst 3750 Metro 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.
Purpose
The Catalyst 3750 Metro switch is supported by a set of enterprise-class features, including Layer 2+
features such as access control lists (ACLs) and quality of service (QoS) and Layer 3 features such as IP
unicast routing, IP multicast routing, and fallback bridging. It also includes features for the service
provider, including multiprotocol label switching (MPLS), Ethernet over MPLS (EoMPLS), hierarchical
QoS, and 802.1Q tunneling.
This guide provides the information you need about the commands that have been created or changed
for use with the Catalyst 3750 Metro 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 that you might encounter. For more information, see the
system message guide for this release.
For documentation updates, see the release notes for this release.
Conventions
