Preface

Audience

The Catalyst 2900 Series XL and Catalyst 3500 Series XL Software Configuration Guide is for the network manager responsible for configuring the Catalyst 2900 series XL and Catalyst 3500 series XL switches, hereafter referred to as the switches. Before using this guide, you should be familiar with the concepts and terminology of Ethernet and local area networking.

Purpose

Note This switch software release is based on Cisco IOS Release 12.0. It has been enhanced to support a set of features for the Catalyst 2900 XL and Catalyst 3500 XL switches. This guide does not repeat the concepts and CLI procedures already documented in the Cisco IOS Release 12.0 documentation on Cisco.com.

Note This guide describes the features for all Catalyst 2900 XL and Catalyst 3500 XL switches, including the Catalyst 2900 LRE XL switches. Cisco IOS Release 12.0(5)WC5 is not for the Long-Reach Ethernet (LRE) switches. Do not install Release 12.0(5)WC5 on the Catalyst 2900 LRE XL switches.

Release 12.0(5)WC4 is for the Catalyst 2900 LRE XL switches only. Do not install Release 12.0(5)WC4 on non-LRE switches.

This guide provides information about configuring and troubleshooting a switch or switch clusters. This guide also provides information about configuring the Cisco Long-Reach Ethernet (LRE) customer premises equipment (CPE) devices. It includes descriptions of the management interface options and the features supported by the switch software.

For these topics, use this guide with other documents:

•Requirements—This guide assumes you have met the hardware and software requirements and cluster compatibility requirements that are described in the release notes.

•Start up information—This guide assumes you have initially configured the switch by using the setup program, as described in the release notes.

•Cluster Management Suite (CMS) information—This guide provides an overview of the CMS web-based, switch management interface. For information about CMS requirements and the procedures for browser and plug-in configuration and accessing CMS, refer to the release notes. For CMS field-level window descriptions and procedures, refer to the CMS online help.

•Cluster configuration—This guide provides information about planning for, creating, and maintaining switch clusters. Because configuring switch clusters is most easily performed through CMS, this guide does not provide the command-line interface (CLI) procedures. For the cluster commands, refer to the Catalyst 2900 Series XL and Catalyst 3500 Series XL Command Reference.

•CLI command information—This guide provides an overview for using the CLI. For complete syntax and usage information about the commands that have been specifically created or changed for the Catalyst 2900 XL or Catalyst 3500 XL switches, refer to the Catalyst 2900 Series XL and Catalyst 3500 Series XL Command Reference.

Note This reference manual provides commands and command descriptions that have been created or changed for the Catalyst 2900 XL and Catalyst 3500 XL switches. It does not repeat the commands and command descriptions already documented in the Cisco IOS Release 12.0 documentation on Cisco.com.

Organization

Technical Assistance Center

The Cisco TAC is available to all customers who need technical assistance with a Cisco product, technology, or solution. Two types of support are available through the Cisco TAC: the Cisco TAC Web Site and the Cisco TAC Escalation Center.

Inquiries to Cisco TAC are categorized according to the urgency of the issue:

•Priority level 4 (P4)—You need information or assistance concerning Cisco product capabilities, product installation, or basic product configuration.

•Priority level 3 (P3)—Your network performance is degraded. Network functionality is noticeably impaired, but most business operations continue.

•Priority level 2 (P2)—Your production network is severely degraded, affecting significant aspects of business operations. No workaround is available.

•Priority level 1 (P1)—Your production network is down, and a critical impact to business operations will occur if service is not restored quickly. No workaround is available.

Which Cisco TAC resource you choose is based on the priority of the problem and the conditions of service contracts, when applicable.

Cisco TAC Web Site

The Cisco TAC Web Site allows you to resolve P3 and P4 issues yourself, saving both cost and time. The site provides around-the-clock access to online tools, knowledge bases, and software. To access the Cisco TAC Web Site, go to the following URL:

http://www.cisco.com/tac

All customers, partners, and resellers who have a valid Cisco services contract have complete access to the technical support resources on the Cisco TAC Web Site. The Cisco TAC Web Site requires a Cisco.com login ID and password. If you have a valid service contract but do not have a login ID or password, go to the following URL to register:

http://www.cisco.com/register/

If you cannot resolve your technical issues by using the Cisco TAC Web Site, and you are a Cisco.com registered user, you can open a case online by using the TAC Case Open tool at the following URL:

http://www.cisco.com/tac/caseopen

If you have Internet access, it is recommended that you open P3 and P4 cases through the Cisco TAC Web Site.

Cisco TAC Escalation Center

The Cisco TAC Escalation Center addresses issues that are classified as priority level 1 or priority level 2; these classifications are assigned when severe network degradation significantly impacts business operations. When you contact the TAC Escalation Center with a P1 or P2 problem, a Cisco TAC engineer will automatically open a case.

To obtain a directory of toll-free Cisco TAC telephone numbers for your country, go to the following URL:

http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml

Before calling, please check with your network operations center to determine the level of Cisco support services to which your company is entitled; for example, SMARTnet, SMARTnet Onsite, or Network Supported Accounts (NSA). In addition, please have available your service agreement number and your product serial number.
