About Cisco IOS Software Documentation

Last Updated: March 26, 2010
This document describes the objectives, audience, conventions, and organization used in Cisco IOS
software documentation. Also included are resources for obtaining technical assistance, additional
documentation, and other information from Cisco. This document is organized into the following
sections:
• Documentation Objectives, page xxi
• Audience, page xxi
• Documentation Conventions, page xxi
• Documentation Organization, page xxiii
• Additional Resources and Documentation Feedback, page xxxi
Documentation Objectives
Cisco IOS documentation describes the tasks and commands available to configure and maintain Cisco
networking devices.
Audience
The Cisco IOS documentation set is intended for users who configure and maintain Cisco networking
devices (such as routers and switches) but who may not be familiar with the configuration and
maintenance tasks, the relationship among tasks, or the Cisco IOS commands necessary to perform
particular tasks. The Cisco IOS documentation set is also intended for those users experienced with
Cisco IOS software who need to know about new features, new configuration options, and new software
characteristics in the current Cisco IOS release.
Documentation Conventions
In Cisco IOS documentation, the term router may be used to refer to various Cisco products; for example,
routers, access servers, and switches. These and other networking devices that support Cisco
IOS
software are shown interchangeably in examples and are used only for illustrative purposes. An example
that shows one product does not necessarily mean that other products are not supported.

Documentation Conventions

Cisco IOS Configuration Fundamentals Command Reference
April 2010
This section contains the following topics:
• Typographic Conventions, page xxii
• Command Syntax Conventions, page xxii
• Software Conventions, page xxiii
• Reader Alert Conventions, page xxiii
Typographic Conventions
Cisco IOS documentation uses the following typographic conventions:
Command Syntax Conventions
Cisco IOS documentation uses the following command syntax conventions:
Convention Description
^ or Ctrl Both the ^ symbol and Ctrl represent the Control (Ctrl) key on a keyboard. For
example, the key combination ^D or Ctrl-D means that you 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 shown in italics. For example, when
setting a Simple Network Management Protocol (SNMP) community string to
public, do not use quotation marks around the string; otherwise, the string will
include the quotation marks.
Convention Description
bold Bold text indicates commands and keywords that you enter as shown.
italic Italic text indicates arguments for which you supply values.
[x] Square brackets enclose an optional keyword or argument.
An ellipsis (three consecutive nonbolded periods without spaces) after a syntax
element indicates that the element can be repeated.

Cisco IOS Documentation Set
The Cisco IOS documentation set consists of the following:
• Release notes and caveats provide information about platform, technology, and feature support for
a release and describe severity 1 (catastrophic), severity 2 (severe), and select severity 3 (moderate)
defects in released Cisco IOS software. Review release notes before other documents to learn
whether updates have been made to a feature.
• Sets of configuration guides and command references organized by technology and published for
each standard Cisco IOS release.
–
Configuration guides—Compilations of documents that provide conceptual and task-oriented
descriptions of Cisco IOS features.

–
Command references—Compilations of command pages in alphabetical order that provide
detailed information about the commands used in the Cisco IOS features and the processes that
comprise the related configuration guides. For each technology, there is a single command
reference that supports all Cisco IOS releases and that is updated at each standard release.
• Lists of all the commands in a specific release and all commands that are new, modified, removed,
or replaced in the release.
• Command reference book for debug commands. Command pages are listed in alphabetical order.
• Reference book for system messages for all Cisco IOS releases.
Cisco IOS Documentation on Cisco.com
The following sections describe the organization of the Cisco IOS documentation set and how to access
various document types.

Feature Guides
Cisco IOS features are documented in feature guides. Feature guides describe one feature or a group of
related features that are supported on many different software releases and platforms. Your Cisco
IOS
software release or platform may not support all the features documented in a feature guide. See the
Feature Information table at the end of the feature guide for information about which features in that
guide are supported in your software release.
Configuration Guides
Configuration guides are provided by technology and release and comprise a set of individual feature
guides relevant to the release and technology.
Command References
Command reference books contain descriptions of Cisco IOS commands that are supported in many
different software releases and on many different platforms. The books are organized by technology. For
information about all Cisco IOS commands, use the Command Lookup Tool at

or the Cisco IOS Master Command List, All Releases, at

Supplementary documents and resources are listed in Table 2 on page xxxi.
Configuration Guides, Command References, and Supplementary Resources
Table 1 lists, in alphabetical order, Cisco IOS software configuration guides and command references,
including brief descriptions of the contents of the documents. The Cisco IOS command references
contain commands for Cisco
IOS software for all releases. The configuration guides and command
references support many different software releases and platforms. Your Cisco
IOS software release or
platform may not support all these technologies.
Table 2 lists documents and resources that supplement the Cisco IOS software configuration guides and
command references. These supplementary resources include release notes and caveats; master
command lists; new, modified, removed, and replaced command lists; system messages; and the debug
command reference.
