About Cisco IOS Software Documentation

This chapter discusses the objectives, audience, organization, and conventions of Cisco IOS software documentation. It also provides sources for obtaining documentation from Cisco Systems.

Documentation Objectives

Cisco IOS software documentation describes the tasks and commands necessary to configure and maintain Cisco networking devices.

Note This release (Release 12.2(13)T) of the Cisco IOS software documentation set contains the set of commands available in Cisco IOS Release 12.2 (mainline) combined with the commands introduced or modified in Cisco IOS Releases 12.2(2)T, 12.2(4)T, 12.2(8)T, 12.2(11)T, and 12.2(13)T.
A list of new and modified commands by 12.2 T release can be obtained from
http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122newft/122tcr/crftnmol.htm

Audience

The Cisco IOS software documentation set is intended primarily for users who configure and maintain Cisco networking devices (such as routers and switches) but who may not be familiar with the tasks, the relationship between tasks, or the Cisco IOS software commands necessary to perform particular tasks.

Documentation Organization

The Cisco IOS software documentation set consists of documentation modules and master indexes. In addition to the main documentation set, there are supporting documents and resources.

Documentation Modules

The Cisco IOS documentation modules consist of configuration guides and corresponding command reference publications. Chapters in a configuration guide describe protocols, configuration tasks, and Cisco IOS software functionality and contain comprehensive configuration examples. Chapters in a command reference publication provide complete Cisco IOS command syntax information. Use each configuration guide in conjunction with its corresponding command reference publication.

The following is a list of the documentation modules available for Cisco IOS Release 12.2(13)T:

•DBR: Cisco IOS Debug Command Reference, Release 12.2 T

•DR: Cisco IOS Dial Technologies Command Reference, Release 12.2 T

•FR: Cisco IOS Configuration Fundamentals Command Reference, Release 12.2 T

•IP1R: Cisco IOS IP Command Reference, Volume 1 of 3: Addressing, Services, and Mobile IP, Release 12.2 T

•IP2R: Cisco IOS IP Command Reference, Volume 2 of 3: Routing Protocols, Release 12.2 T

•IP3R: Cisco IOS IP Command Reference, Volume 3 of 3: Multicast, Release 12.2 T

Master Indexes

A consolidated master index for the Cisco IOS Release 12.2(13)T command references will be released shortly after the publication of the individual documentation modules. Individual books also contain a book-specific index.

The master indexes provide a quick way for you to find a command when you know the command name but not which module contains the command. When you use the online master indexes, you can click the page number for an index entry and go to that page in the online document.

Supporting Documents and Resources

The following documents and resources support the Cisco IOS software documentation set:

•Cisco IOS Debug Command Reference—This publication contains an alphabetical listing of the debug commands and their descriptions. Documentation for each command includes a brief description of its use, command syntax, usage guidelines, and sample output.

•Internetworking Terms and Acronyms—This Cisco publication compiles and defines the terms and acronyms used in the internetworking industry.

•New feature documentation—Feature module documentation introduces new networking functionality, released after the publication of the Cisco IOS software documentation set, that supports Cisco networking technology and hardware.

•Release notes—This documentation describes system requirements, provides new and changed information, and includes other useful information about specific software releases.

•Caveats documentation—This documentation provides information about Cisco IOS software defects in specific software releases.

Document Conventions

The Cisco IOS documentation set uses the following conventions:

Convention
Description

^ or Ctrl

The ^ and Ctrl symbols represent the Control key. For example, the key combination ^D or Ctrl-D means hold down the Control key while you press the D key. Keys are indicated in capital letters but are not case sensitive.

string

A string is a nonquoted set of characters. For example, when setting an SNMP community string to public, do not use quotation marks around the string or the string will include the quotation marks.


Examples use the following conventions:

Convention
Description 
screen

Examples of information displayed on the screen are set in Courier font. 

boldface screen

Examples of text that you must enter are set in Courier bold font.

<     >

Angle brackets enclose nonprinting characters, such as passwords.

!

An exclamation point at the beginning of a line indicates a comment line. (Exclamation points are also displayed by the Cisco IOS software for certain processes.)

[     ]

Square brackets enclose default responses to system prompts.


The following conventions are used to attract the attention of the reader:

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

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

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

Within Cisco IOS software documentation, the term router is generally used to refer to a variety of Cisco products (for example, routers, access servers, and switches). Routers, access servers, and other networking devices that support Cisco IOS software are shown interchangeably within examples. These products are used only for illustrative purposes; that is, an example that shows one product does not necessarily indicate that other products are not supported.
