These release notes discuss the new features and caveats for the Cisco 4000 series for Cisco IOS Release 11.3(1) T. Use this document in conjunction with Release Notes for Cisco IOS Release 11.3. The software caveats that apply to Release 11.3 also apply to Release 11.3 T.
Additional information on Release 11.3(1) T, including software configuration information and Cisco IOS commands, are available on the World Wide Web and the Documentation CD-ROM. (See the section "Online Navigation" later in this document.)
These release notes discuss the following topics:

For more information about the features introduced in these release notes, refer to the Feature Guide for Cisco IOS Release 11.3(1) T and the Cisco IOS Software Release 11.3(1) T Content and Platform Support Product Bulletin. These release notes should also be used in conjunction with Release Notes for Cisco IOS Release 11.3, which contains some feature and caveat information applicable to Release 11.3(1) T.
The related documents mentioned above, in addition to detailed software configuration information on the features and Cisco IOS commands supported by Release 11.3(1) T, are available on the Web and on the Documentation CD-ROM. (See the "Online Navigation" section later in this document.)
The Cisco IOS software documentation is divided into nine modules and two master indexes. There are also four supporting documents.
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.
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 Cisco IOS documentation set consists of the following books and chapter topics:

On CCO and the CD-ROM, the main path is as follows:
Cisco Connection Online: Products and Ordering: Documentation: Cisco Documentation: Cisco Product Documentation: Cisco IOS Software Configuration: Cisco IOS Release 11.3:
For Product Bulletins on CCO and the CD-ROM, the path is as follows:

The following new features are supported by the Cisco 4000 series in Cisco IOS Release 11.3(1) T:
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. The feature set matrix is used to see the overall feature set organization.
The feature set matrix (See Table 1) shows the new feature set organization and lists which feature sets are available on the Cisco 4000 series for Release 11.3(1) T. The matrix uses the following symbols:
| Feature Set Matrix Symbol | Description |
|---|---|
| Basic | This feature is offered in the basic feature set. |
| Plus | This feature is offered in the Plus feature set |
| Encrypt | This feature is offered in the encryption feature sets, which consist of 40-bit (Plus 40) or 56-bit (Plus 56) data encryption feature sets. |
| Standard Feature Sets | Cisco 4000 Series |
|---|---|
| IP | Basic, Plus, Encrypt |
| Desktop (IP/IPX/AppleTalk/DEC) | Basic, Plus |
| Enterprise | Plus, Encrypt |
| Enterprise APPN | Plus, Encrypt |
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 might 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.
To determine what features are available with each feature set, see Table 2. The table summarize what features you can use when running a specific feature set on the Cisco 4000 series for Cisco IOS Release 11.3(1) T. The feature set table uses the following symbols:
| Feature Set Table Symbol | Description |

Table 3 describes the memory requirements for the Cisco 4000 series platform's feature set supported by Cisco IOS Release 11.3(1) T.
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(1) T features, you must upgrade the code or main system memory as listed in Table 3. Some platforms have specific chip or architecture requirements that affect what can be upgraded and in what increments.

For information on upgrading to a new software release, refer to the Cisco IOS Software Release Upgrade Paths and Packaging Simplification Product Bulletin #703.
You can access this product bulletin on the Web at http://www.cisco.com, http://www-europe.cisco.com, or http://www-china.cisco.com, or on the Documentation CD-ROM.
The path is as follows:
Cisco Connection Online: Products and Ordering: More Information: Product Bulletins: Cisco IOS Release 11.3: Cisco IOS Software Release 11.3 Upgrade Paths (#703, 12/97)
This section describes possibly unexpected behavior by Release 11.3(1) T. Unless otherwise noted, these caveats apply to all 11.3 releases up to and including 11.3(1) T.
When frame relay traffic shaping is enabled on a serial interface, disabling and re-enabling weighted fair queuing will cause a system restart. [CSCdj58431]
The map-class commands frame-relay bc out and frame-relay be out are accepted by the enterprise image. These parameters are relevant for SVC setup. However, the traffic shaping code does not use them. As a result, the values appear to be unset.
This behavior can be avoided by using the command:
frame-relay bc number frame-relay be number

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 the Cisco 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:
For a copy of CCO's Frequently Asked Questions (FAQ), contact cco-help@cisco.com. For additional information, contact cco-team@cisco.com.
Cisco documentation and additional literature are available in a CD-ROM, which ships with your product. The Documentation CD-ROM, a member of the Cisco Connection Family, is updated monthly. Therefore, it might be more up to date than printed documentation. To order additional copies of the Documentation CD-ROM, contact your local sales representative or call customer service. The CD-ROM is available as a single unit 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.
