About This Manual

This section discusses the objectives, audience, organization, use, and conventions of the Feature Guide for Cisco IOS Release 11.2 BC.

Document Objectives

This document describes new features that are available in Cisco IOS Release 11.2 BC, up to and including Release 11.2(11)BC. You can use this document to learn about and configure these new features.

This document does not describe features that are available in Release 11.2, Release 11.2 F, or Release 11.2 P. For information about features in Release 11.2, refer to the Release Notes for Cisco IOS Release 11.2. For information about features in Release 11.2 P, refer to the Release Notes for Cisco IOS Release 11.2 P and Feature Guide for Cisco IOS Release 11.2 P. For information about features in Release 11.2 F, refer to the Release Notes for Cisco IOS Release 11.2 F and Feature Guide for Cisco IOS Release 11.2 F.

Because this document describes new features only, you might need to use this document in conjunction with the Cisco IOS Release 11.2 configuration guides and command references in order to obtain complete configuration information.

For information about software caveats against Release 11.2 BC, refer to the Release Notes for Cisco IOS Release 11.2 BC.

Note Cisco IOS Release 11.2 (8)BC is the initial release of the Release 11.2 BC software. There are no predecessors to Release 11.2 (8)BC.

Audience

This document is intended for users who configure and maintain Cisco IOS software but who are not necessarily familiar with specific tasks, the relationships between tasks, or the commands necessary to perform particular tasks.

Document Organization

This document contains a single main part. This main part contains new features for the following Release 11.2 BC releases:

Release 11.2(8)BC Features
Release 11.2(10)BC Features

Each "Release 11.2(x)BC Features" part contains an alphabetical listing of new features for that release. Each feature chapter describes the feature, lists the hardware platforms that the feature can run on, identifies any configuration prerequisites, provides configuration tasks and examples, and describes new or modified commands associated with the feature.

Note No new features were released or documented for 11.2(9)BC and 11.2(11)BC.

Document Use

This feature guide is published at each 11.2 BC maintenance release. With each publication a new part, which contains the features associated with that maintenance release, is added to this guide.

Features documented in earlier 11.2 BC releases also apply to the current release because software features supported in earlier 11.2 BC releases are also supported in the current release. For example, if you were to run Release 11.2(11)BC, the documentation in parts up to and including Release 11.2(8)BC applies to features supported in your software.

Document Conventions

This document uses the following conventions:

The caret character (^) represents the Control key.

: For example, the key combinations ^D and Ctrl-D are equivalent: Both mean hold down the Control key while you press the D key. Keys are indicated in capitals, but are not case sensitive.

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.

Command descriptions use these conventions:

Boldface indicates commands and keywords that are entered literally as shown.
Italics indicate arguments for which you supply values; in contexts that do not allow italics, arguments are enclosed in angle brackets (< >).
Square brackets ([ ]) indicate optional elements.
Braces ({ }) group required choices, and vertical bars ( | ) separate the alternative elements.
Braces and vertical bars within square brackets ([{ | }]) indicate a required choice within an optional element.

Examples use these conventions:

Examples that contain system prompts denote interactive sessions, indicating that the user enters commands at the prompt. The system prompt indicates the current command mode. For example, the prompt Router(config)# indicates global configuration mode.
Terminal sessions and information the system displays are in screen font.
Information you enter is in boldface screen font.
Nonprinting characters, such as passwords, are in angle brackets (< >).
Default responses to system prompts are in square 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.

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.

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. When a feature is supported on one or more specific router platforms (such as the Cisco 4500), but not on other platforms (such as the Cisco 2500), the text specifies the supported platforms.

The features describe in the Feature Guide for Cisco IOS Release 11.2 BC operate on a Cisco 7000 series router with the RSP7000 installed and on the Cisco 7500 series router.
