Catalyst 3750 Switch Command Reference

Preface
Audience
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.
Purpose
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, refer to 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, refer to the software configuration guide for this release.
This guide does not describe system messages you might encounter. For more information, refer to the
system message guide for this release.

Opening a TAC Case
Using the online TAC Case Open Tool is the fastest way to open P3 and P4 cases. (P3 and P4 cases are
those in which your network is minimally impaired or for which you require product information.) After
you describe your situation, the TAC Case Open Tool automatically recommends resources for an
immediate solution. If your issue is not resolved using the recommended resources, your case will be
assigned to a Cisco TAC engineer. The online TAC Case Open Tool is located at this URL:
http://www.cisco.com/tac/caseopen
For P1 or P2 cases (P1 and P2 cases are those in which your production network is down or severely
degraded) or if you do not have Internet access, contact Cisco TAC by telephone. Cisco TAC engineers
are assigned immediately to P1 and P2 cases to help keep your business operations running smoothly.
To open a case by telephone, use one of the following numbers:
Asia-Pacific: [phone] (Australia: 1 800 805 227)
EMEA: [phone]
USA: 1 800 553-2447
For a complete listing of Cisco TAC contacts, go to this URL:
http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml
TAC Case Priority Definitions
To ensure that all cases are reported in a standard format, Cisco has established case priority definitions.
Priority 1 (P1)—Your network is “down” or there is a critical impact to your business operations. You
and Cisco will commit all necessary resources around the clock to resolve the situation.
Priority 2 (P2)—Operation of an existing network is severely degraded, or significant aspects of your
business operation are negatively affected by inadequate performance of Cisco products. You and Cisco
will commit full-time resources during normal business hours to resolve the situation.
Priority 3 (P3)—Operational performance of your network is impaired, but most business operations
remain functional. You and Cisco will commit resources during normal business hours to restore service
to satisfactory levels.
Priority 4 (P4)—You require information or assistance with Cisco product capabilities, installation, or
configuration. There is little or no effect on your business operations.
