(DRAFT LABEL) ALPHA DRAFT - CISCO CONFIDENTIAL
About the Cisco IOS Software Documentation
This section discusses the objectives, audience, organization, and conventions of the Cisco IOS software
documentation. It also discusses how to obtain documentation on Cisco Connection Online and the
Documentation CD-ROM.
Documentation Objectives
This Cisco IOS software documentation describes the tasks and commands necessary to configure and
maintain your access server or router.
Audience
The Cisco IOS software documentation is intended primarily for users who configure and maintain
access servers and routers, but are not necessarily familiar with tasks, the relationship between tasks, or
the commands necessary to perform particular tasks.
Documentation Organization
The Cisco IOS software documentation is divided into 12 modules and two master indexes. In addition
to the main documentation set, there are four supporting documents.
Documentation Modules
Each module consists of two books: a configuration guide and a corresponding command reference.
Chapters in a configuration guide describe protocols, configuration tasks, and Cisco IOS software
functionality and contain comprehensive configuration examples. Chapters in a command reference
provide complete command syntax information. Each configuration guide can be used in conjunction
with its corresponding command reference.
Master Indexes
Two master indexes provide indexing information for the Cisco IOS software documentation set: an
index for the configuration guides and an index for the command references. In addition, individual
books contain a book-specific index.

The following documents support the Cisco IOS software documentation set:
• Cisco IOS Software Command Summary
• Cisco IOS Software System Error Messages
• Debug Command Reference
• Dial Solutions Quick Configuration Guide
Document Conventions
The Cisco IOS documentation set uses the following conventions:
Examples use the following conventions:
The following conventions are used to attract the reader’s attention:
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.
Convention Description
^ or Ctrl Represents the Control key. For example, when you read ^D or Ctrl-D, you
should 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 defined as a nonquoted set of characters. For example, when
setting an SNMP community string to public, do not use quotation marks
around the string; otherwise, the string will include the quotation marks.
Convention Description
screen Shows an example of information displayed on the screen.
boldface screen Shows an example of information that you must enter.
< > Nonprinting characters, such as passwords, appear in angled brackets.
! Exclamation points at the beginning of a line indicate a comment line. They
are also displayed by the Cisco IOS software for certain processes.
[ ] Default responses to system prompts appear in square brackets.
Command Syntax Conventions
About the Cisco IOS Software Documentation v
(DRAFT LABEL) ALPHA DRAFT - CISCO CONFIDENTIAL
MOD
Within the Cisco IOS software documentation, the term router is used to refer to both access servers
and routers. When a feature is supported on the access server only, the term access server is used.
Within examples, routers and access servers are alternately shown. These products are used only for
example purposes; that is, an example that shows one product does not indicate that the other product
is not supported.
Command Syntax Conventions
Command descriptions use the following conventions:
Cisco Connection Online
Cisco Connection Online (CCO) is Cisco Systems’ primary, real-time support channel. Maintenance
customers and partners can self-register on CCO to obtain additional information and services.
Available 24 hours a day, 7 days a week, CCO provides a wealth of standard and value-added services
to Cisco’s customers and business partners. CCO services include product information, product
documentation, software updates, release notes, technical tips, the Bug Navigator, configuration notes,
brochures, descriptions of service offerings, and download access to public and authorized files.
CCO serves a wide variety of users through two interfaces that are updated and enhanced
simultaneously: a character-based version and a multimedia version that resides on the World Wide Web
(WWW). The character-based CCO supports Zmodem, Kermit, Xmodem, FTP, and Internet e-mail, and
it is excellent for quick access to information over lower bandwidths. The WWW version of CCO
provides richly formatted documents with photographs, figures, graphics, and video, as well as
hyperlinks to related information.
You can access CCO in the following ways:
• WWW: http://www.cisco.com
• WWW: http://www-europe.cisco.com
• WWW: http://www-china.cisco.com
• Telnet: cco.cisco.com
• Modem: From North America, 408 526-8070; from Europe, 33 1 64 46 40 82. Use the following
terminal settings: VT100 emulation; databits: 8; parity: none; stop bits: 1; and connection rates up
to 28.8 kbps.
Convention Description
boldface Indicates commands and keywords that are entered literally as shown.
italics Indicates arguments for which you supply values; in contexts that do not
allow italics, arguments are enclosed in angle brackets (< >).
[x] Keywords or arguments that appear within square brackets are optional.
{x | y | z} A choice of required keywords (represented by x, y, and z) appears in braces
separated by vertical bars. You must select one.
[x {y | z}] Braces and vertical bars within square brackets indicate a required choice
within an optional element. You do not need to select one. If you do, you
have some required choices.

Note If you are a network administrator and need personal technical assistance with a Cisco product that is
under warranty or covered by a maintenance contract, contact Cisco’s Technical Assistance Center
(TAC) at 800 553-2447, 408 526-7209, or tac@cisco.com. To obtain general information about Cisco
Systems, Cisco products, or upgrades, contact 800 553-6387, 408 526-7208, or cs-rep@cisco.com.
Documentation CD-ROM
Cisco documentation and additional literature are available in a CD-ROM package, which ships with
your product. The Documentation CD-ROM, a member of the Cisco Connection Family, is updated
monthly. Therefore, it might be more current than printed documentation. To order additional copies
of the Documentation CD-ROM, contact your local sales representative or call customer service. The
CD-ROM package is available as a single package or as an annual subscription. You can also access
Cisco documentation on the World Wide Web at http://www.cisco.com, http://www-china.cisco.com, or
http://www-europe.cisco.com.
If you are reading Cisco product documentation on
the World Wide Web, you can submit comments
