These release notes describe the new features and significant software components for Cisco IOS Release 11.3 for Cisco 1600 series routers. For detailed information about the features and caveats in these release notes, refer to the Release Notes for Cisco IOS Release 11.3 publication, which contains features and caveats for all 11.3 platforms. This publication is available on the Documentation CD-ROM and on Cisco Connection Online (CCO), which are described in the section "Online Navigation."
These release notes discuss the following topics:
To determine which Cisco IOS software release is running on your Cisco 1600 series router, log on to the router and enter the show version User EXEC command, as shown below:

The Cisco 1600 series of access routers deliver the next-generation set of features and benefits for small-office Internet and intranet access: WAN flexibility, end-to-end security, end-to-end quality of service, ease of use, deployment, and management. Cisco 1600 series routers connect small offices with Ethernet LANs to the public Internet and to a company's internal intranet or corporate LAN through several WAN connections such as ISDN, asynchronous serial, and synchronous serial. Cisco 1600 series routers include the following models: the Cisco 1601, Cisco 1602, Cisco 1603, and Cisco 1604.
All Cisco 1600 series models include one Ethernet port, one built-in WAN port, and one WAN interface card expansion slot for additional connectivity and flexibility. The Cisco 1601 includes a built-in serial WAN port; the Cisco 1602 has an onboard 56-kbps four-wire channel service unit/data service unit (CSU/DSU); the Cisco 1603 has an ISDN BRI S/T port; and the Cisco 1604 includes an ISDN BRI U interface with a built-in NT1 device.
The following are 1-port WAN interface cards supported by the Cisco 1600 series routers:
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:

New online navigation enhancements for Release 11.3 include:
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.
Release 11.3 supports features in the following categories:
Detailed descriptions of the features are available on the Documentation CD-ROM and on CCO:
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 1 provides a matrix of the new feature set organization and shows which feature sets are available on the Cisco 1600 series routers. These feature sets only apply to Cisco IOS Release 11.3.
The tables use the following conventions to identify feature sets:
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.

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.
For instructions on downloading a current Cisco IOS release from the CCO Trivial File Transfer Protocol (TFTP) server, go to the following URL. This URL is subject to change without notice.
http://www.cisco.com/kobayashi/sw-center
The Software Center window is displayed.
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.
Step 5 Hardware
Step 6 Release
Step 7 Software and hardware release
Step 8 Click Execute. The software release is downloaded to your desktop computer.
Step 9 Transfer the software release to a local TFTP server on your network, using a terminal emulation application, such as TCP Connect.
Step 10 Log on to your router. Copy the software release from your TFTP server to your router, using the copy tftp command.
Table 3 describes the memory requirements for the Cisco 1600 series platform feature set supported by Cisco IOS Release 11.3. 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.
| Platform/Feature Set | Minimum Required Code Memory | Required Main Memory | Release 11.3 Runs from |
|---|---|---|---|
| IP | 4 MB Flash | 2 MB DRAM | Flash |
| IP Plus | 6 MB Flash | 4 MB DRAM | Flash |
| IP Plus 40 | 6 MB Flash | 4 MB DRAM | Flash |
| IP Plus 56 | 6 MB Flash | 4 MB DRAM | Flash |
| IP/IPX | 6 MB Flash | 2 MB DRAM | Flash |
| IP/IPX Plus | 6 MB Flash | 4 MB DRAM | Flash |
| IP/IPX/AT/IBM | 8 MB Flash | 4 MB DRAM | Flash |
| IP/IPX/AT/IBM Plus | 8 MB Flash | 6 MB DRAM | Flash |
| IP/IPX/AT/IBM Plus 40 | 8 MB Flash | 6 MB DRAM | Flash |
| IP/IPX/AT/IBM Plus 56 | 8 MB Flash | 6 MB DRAM | Flash |
Possibly unexpected behavior in Cisco IOS Release 11.3 exists in the following areas:
A complete list of the caveats, including descriptions and possible workarounds, is available on the Documentation CD-ROM and on CCO:
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:
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 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 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 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.
