Preface

This preface describes the objectives, audience, organization, and conventions of the Cisco 1700 Series Router Software Configuration Guide. It also provides information about additional documentation and about how to obtain technical assistance.

Objectives

This software configuration guide explains how to configure Cisco 1700 routers. It does not cover every feature, but it does describe, in detail, the tasks most commonly required for configuring the router.

This guide also references detailed features described in the Cisco IOS configuration guides and command references. Refer to those other books for additional information.

Audience

This guide is intended both for network administrators who have no or little experience configuring routers and for network administrators who have extensive experience. This guide is useful for both the following situations:

•You have a router that is already configured, and you want to configure additional features, using the command-line interface (CLI).

•You want to configure the router by using only the CLI.

Organization

This document contains the following chapters and appendixes:

•"Introduction to Router Configuration"—Describes what you need to know about the Cisco IOS software (the software that runs the router) before you begin to configure the router.

•"Configuring Security Features"—Describes how to configure security features on Cisco routers, including IP Security (IPSec), firewalls, and virtual private dial-up networks (VPDNs).

•"Miscellaneous Features"—Provides procedures for configuring miscellaneous features of the Cisco 1700 Series routers: Dynamic Host Configuration Protocol (DHCP) and Network Address Translation (NAT).

•"Configuring Routing Among VLANs with IEEE 802.1Q Encapsulation"—Describes the required and optional tasks for configuring routing between VLANs with IEEE 802.1Q encapsulation.

•"Configuring ISDN"—Describes how to configure a Cisco router to dial into a central-site router over an Integrated Services Digital Network (ISDN) line.

•"Configuring a Leased Line"—Describes how to configure a Cisco router for Internet Protocol (IP) and Internetwork Packet Exchange (IPX) over a private synchronous serial line.

•"Configuring Frame Relay"—Describes how to configure a Cisco router to connect to a central-site router over a Frame Relay line.

•"Configuring Asynchronous Connections"—Describes how to configure a Cisco router to dial into a central-site router over a standard telephone line.

•Chapter 9, "Configuring X.25"—Describes how to configure a Cisco router to connect to a central-site router over an X.25 line.

•"Networking Concepts"—Describes concepts that can help you in designing your network and configuring your router according to the examples in this guide.

•"ROM Monitor"—Describes the functions and commands of the router ROM monitor (also called the bootstrap program), the firmware that runs when the router is powered up or reset.

Conventions

This document uses the following conventions:

•The caret character (^) represents the Control key.

For example, the key combinations ^D and Ctrl-D mean the same thing: Hold down the Control key while you press the D key. Although keys are indicated in capital letters, they are not case sensitive.

Command descriptions use these conventions:

•Commands and keywords in boldface font.

•Variables for which you supply values are in italic font.

Examples use these conventions:

•Examples that contain system prompts denote interactive sessions, indicating that you enter commands at the prompt. The system prompt indicates the current command mode. For example, the following prompt indicates global configuration mode:
Router(config)#
•Terminal sessions and information that the system displays are in screen font.

•Information that you enter is in boldface screen font.

•Nonprinting characters, such as passwords, are in angle brackets (< >).

Note Means reader take note. Notes contain helpful suggestions or references to materials not contained in this manual.

Caution Means reader be careful. In this situation, you might do something that could result in equipment damage or loss of data.

Timesaver Means the described action saves time. You can save time by performing the action described in the paragraph.

Related Documentation

The following publications provide related information about this product:

•Cisco IOS command references and configuration guides for Cisco IOS Release 12.2 provide complete information about all Cisco IOS CLI commands and how to use them, as well as information on designing and configuring LANs and WANs.

•The Quick Start Guide that comes with your router has instructions for quickly cabling and powering up the router.

•The Hardware Installation Guide for your router, which is available online, describes router features, tells how to install and cable the router, and tells how to troubleshoot common problems you may have with it.

Obtaining Documentation

The following sections explain how to obtain documentation from Cisco Systems.

World Wide Web

You can access the most current Cisco documentation on the World Wide Web at the following URL:

http://www.cisco.com

Translated documentation is available at the following URL:

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.
