Related Cisco IOS Documentation

The Cisco IOS software documentation is divided into nine modules and two master indexes. There are also 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.

---

Note The most up-to-date Cisco IOS documentation can be found on the latest Documentation CD-ROM and on the Web. These electronic documents might contain updates and modifications made after the paper documents were printed.

Online Navigation

The Cisco IOS software documentation set is available as printed manuals or electronic documents. You can access the electronic documents either on the Cisco Documentation CD-ROM or at Cisco Connection Online (CCO) on the World Wide Web:

• On the Documentation CD-ROM, go to Cisco Product Documentation, select Cisco IOS Software Configuration, and then select Cisco IOS Release 11.3.

• On CCO, go to Software and Support and select Documentation. Next, select Documentation, click on Cisco IOS Software Configuration, and then click on Cisco IOS Release 11.3.

New online navigation enhancements for Release 11.3 include:

• Online hot-linked master indexes for configuration guide and command reference documentation sets.

On the Documentation CD-ROM or CCO, go to Cisco IOS Release 11.3 and select Cisco IOS Release 11.3 Configuration Guides, Command References. Then select Configuration Guide Master Index or Command Reference Master Index. To access documentation related to an index entry, click on the page number following the entry.

• Online hot-linked list of features that are new since Release 11.2.

On the Documentation CD-ROM or CCO, go to Cisco IOS Release 11.3 and select Cisco IOS Release 11.3 Configuration Guides, Command References. Next, select Cisco IOS 11.3 New Features.

To access configuration documentation for a feature, do one of the following:

• Click on the page number following the feature name. This takes you to the page on which the feature is documented.

• Using your browser's Search function, search on one or more keywords from the feature name. This displays the feature documentation on your screen.

For additional information about the Documentation CD-ROM and CCO, refer to the sections "Cisco Connection Online" and "Documentation CD-ROM" at the end of these release notes.

New Software Features in Release 11.3(1)

Release 11.3 supports features in the following categories:

• IBM Support

• Internet

• IP Routing

• Internet

• LAN Support

• Management

• Multimedia

• Quality of Service

• Security

• Switching

• Terminal Services

• WAN Optimization

• WAN Services

Detailed descriptions of the features are available on the Documentation CD-ROM and on CCO:

• On the Documentation CD-ROM, go to Cisco Product Documentation, select Cisco IOS Software Configuration, click on Cisco IOS Release 11.3, then select Release Notes for Cisco IOS Release 11.3. From the bulleted list, select New Features for Release 11.3.

• From the CCO web page, go to Cisco Documentation, click on Cisco IOS Software Configuration, select Cisco IOS Release 11.3, and then select Release Notes for Cisco IOS Release 11.3. From the bulleted list, select New Features for Release 11.3.

New Hardware Support in Release 11.3(1)

The following platform enhancement has been added to Release 11.3:

Selective Packet Discard (SPD)--When in severe overload conditions, routers that cannot keep up with the incoming packet stream must drop packets. If no intelligence is applied to choosing which ones to discard, this impacts the stability of routing protocols. This feature applies some simple choices to selectively discard packets likely to be unimportant for routing and interface stability. SPD is enabled by default; there are no commands or configuration tasks required.

Cisco IOS Feature Sets for Cisco 1000 Series Routers

The Cisco IOS software is packaged into "feature sets" (also called "software images"). There are many different feature sets available, and each feature set contains a specific subset of Cisco IOS features. Table 3 provides a matrix of the new feature set organization and shows which feature sets are available on the Cisco 1000 series routers. These feature sets only apply to Cisco IOS Release 11.3.

The tables use the following conventions to identify feature sets:

• Yes: the feature set is offered for the platform

• No : the feature set is not offered for the platform

• Plus: a value-added option that contains a variable set of additional features depending on the hardware platform selected

• Plus 40: a value-added option that contains a variable set of additional features depending on the hardware platform selected, including 40-bit data encryption

• Plus 56: a value-added option that contains a variable set of additional features depending on the hardware platform selected, including 56-bit data encryption

Cisco IOS images with strong encryption (including, but not limited to, 56-bit DES) are subject to U.S. government export controls and have a limited distribution. Images to be installed outside the U.S. require an export license. Customer orders may be denied or subject to delay due to U.S. government regulations. Contact your sales representative or distributor for more information, or send e-mail to export@cisco.com.

Upgrading to a New Software Release

If you are upgrading to Cisco IOS Release 11.3 from an earlier Cisco IOS software release, you should save your current configuration file before configuring your access server with the Cisco IOS Release 11.3 software. An unrecoverable error could occur during download or configuration.

---

Note Before downloading a software upgrade, read Product Bulletin #703, Cisco IOS Software Release Upgrade Paths and Packaging Simplification. The information in this bulletin supersedes the following instructions.

Step 1 Click Cisco IOS Software. The Cisco IOS Software window is displayed.

Step 2 Click Cisco IOS 11.3. The Cisco 11.3 Software Upgrade Planner window is displayed.

Step 3 Click Download Cisco IOS 11.3 Software. The Software Checklist window is displayed.

Step 4 Select the appropriate information in each section of the Software Checklist window.

• Hardware

• Release

• Software and hardware release

Step 5 Click Execute. The software release is downloaded to your desktop computer.

Step 6 Transfer the software release to a local TFTP server on your network using a terminal emulation software application such as TCP Connect.

Step 7 Log on to your router. Copy the software release from your TFTP server to your router, using the copy tftp command.

Memory Requirements

Table 6 and Table 7 describe the memory requirements for the Cisco 1000 series platform feature set supported by Cisco IOS Release 11.3. Beginning with Cisco IOS Release 10.3, some software image sizes exceed 4 MB and, when compressed, exceed 2 MB. Also, some systems now require more than 1 MB of main system memory for data structure tables.

For Cisco routers to take advantage of the Release 11.3 features, you must upgrade the code or main system memory. Some platforms have specific chip or architecture requirements that affect what can be upgraded and in what increments.
