How to Use These Release Notes

The tables in these release notes contain details about Cisco feature packs. Use these tables to perform the following tasks before loading a software image onto a router:

1. Use Table 1, "Cisco 3600 Series Routers Default Memory and Upgrade Options," to find the factory-default memory and available upgrades for your router.

2. Use Table 2, "Feature Pack Product Numbers," to identify the software image to load.

3. Use Table 3, "Cisco Feature Pack Image Filenames and Memory Requirements," to find the memory required for this image.

4. Use the tables in the "Feature Set Tables" section to identify the features supported in a feature set image.

What Is a Feature Pack?

A feature pack contains the following items:

The heart of a feature pack is the CD-ROM that contains software images and the RSL, which is a Windows 95 application that loads an image onto a router or access server. Each feature pack CD-ROM contains at least one Cisco IOS feature set. The CD booklet Getting Started with the Router Software Loader explains how to use the RSL to install the router image. If you cannot use the RSL to load images, you can follow the instructions in the "Alternatives to RSL" section.

Before running the RSL, read the "Installing Software Images Using RSL" section. If you are loading software on a preconfigured router, you should save the router configuration file on your PC before beginning the image download process, as described in Getting Started with the Router Software Loader.

Feature Pack Overview Table

Table 3 identifies each feature pack as specified on the router software CD-ROM label, the feature sets in each feature pack, and UNIX and DOS filenames of the images, memory requirements, and RSL installer descriptions.

Feature Set Tables

Cisco IOS software is packaged as feature sets (or images), each containing a subset of Cisco IOS features. The following conventions identify feature sets:

Cisco IOS images with strong encryption (including, but not limited to, 56-bit and 168-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.

The following list shows feature sets supported on Cisco 3600 series routers by Cisco IOS Releases 12.0(5)T1 and 12.0(5)XK1:

Table 4 and Table 5 list features supported by Cisco 3600 series routers in each Cisco IOS Release 12.0(5)T1 and 12.0(5)XK1 feature set.

Installation Notes

This section describes the following topics:

Installing Software Images Using RSL

This section describes some solutions to problems you might encounter when installing software images using RSL. These solutions are additions to the RSL online help.

Recovering from a Connection Error

This installation tip provides a possible recovery solution if you are unable to connect to your router. You can skip this section unless you are experiencing a connection error.

In some cases, you might receive the following error message while connecting to the target router:

If you encounter this message, especially if you are connecting to a router that has a large configuration file or many interfaces, try increasing the Short Timeout to a value higher than 25 seconds in the Options dialog box.

Restoring the Startup Configuration

In some cases, the RSL is unable to restore the startup configuration. If this happens, take the following steps:

Step 2   Restart the RSL, and connect by using the Preconfigured router option.

Step 3   When asked if you want to overwrite the existing startup configuration file, choose no.

Step 4   When asked if you want to continue, choose yes.

Step 5   When the router is connected, select Download Router Configuration in the Router Software Loader dialog box.

Step 6   Select the appropriate file, and click the Copy configuration to the router nonvolatile memory button.

The router should now contain the startup configuration it had before the initial RSL connection. You can now exit the RSL.

Installation Tips

The following information about RSL operations can help you with the installation process:

Alternatives to RSL

The RSL is designed to work with a PC running Microsoft Windows 95 and is the recommended method for downloading software to the router. The booklet included with the CD-ROM explains how to perform this simple install process; however, two alternatives are available for installing router software:

Installing the Router Software Using the Console or Auxiliary Port

This section explains how to use the copy xmodem flash command to install the router software from the CD-ROM on the router.

The following example shows how to use the copy xmodem flash command on a Cisco 3600 series router:

Installing the Router Software Using a TFTP Server Application

Use this TFTP server application method as an alternative to using the RSL to install the router software from the CD-ROM. You can perform this procedure using a PC (running Microsoft Windows 95 or Microsoft Windows 3.1), a Macintosh, or a UNIX system. You can use either the copy tftp flash or copy rcp flash command to download the router software to the router.

First, obtain a TFTP application or a remote copy protocol (rcp) application to set up your computer as a TFTP server or an rcp server. Use the RSL or the TFTP server included on the feature pack CD-ROM to install the router software only if you are using a PC running Windows 95.

For other operating systems, a number of TFTP or rcp applications are available from independent software vendors or available as shareware from public sources on the World Wide Web.

Step 2   Launch the TFTP server application on the PC, usually by double-clicking the application icon or its .exe filename.

Step 3   Set up the PC as a TFTP server by using the TFTP server application setup or configuration facility.

Most TFTP server applications include a setup facility that allows you to specify the PC as a server. For example, from the TFTP menu of one application, you can select Settings to display a panel, and configure the local PC as a server by selecting the Server checkbox.

The TFTP server also allows the selection of a "root" directory. You must select the directory in which the Cisco IOS files reside (for example, d:\cpswinst\images).

Step 4   Establish a console session from your local PC (which is now configured as a TFTP server) to the Cisco router by using one of these methods:

This is the recommended method.When you reload the router with the new image in Step 16, you remain connected to the router. (If you use Telnet, you lose connection to the router.)

Step 5   Connect your PC Ethernet port to the corresponding router LAN port. Use the 10BaseT crossover cable to connect to an Ethernet port. Use straight-through cables if you are connecting via a 10BaseT hub or a 100BaseT hub.

Note Cisco recommends that you back up the router configuration before upgrading the router software.

Step 6   Enter the following commands to set the configuration register to 0x2101 and reload to the bootstrap image:

Step 7   When asked whether the system configuration has been modified, enter yes:

Step 8   If the password prompt appears, enter the password:

Step 9   At the router prompt, enter enable and then the password:

Step 10   Copy the new software image from the PC CD-ROM drive to the router:

Router(boot)(config)# copy tftp flash

In the next series of steps, you download the Cisco IOS Release 12.0(5)T1 images that you want installed on your router.

Step 11   When prompted, enter the IP address of your PC, as in the following example:

Address or name of remote host [255.255.255.255]? 131.108.1.1

This is the IP address of your local PC, not that of the router.

Step 12   When prompted, enter the filename of the Cisco IOS Release 12.0(5)T1 image to be copied to the router, as in the following example:

This example specifies the DOS image name of the IP feature set for Cisco 3600 series routers (as shown in Table 3).

Step 13   In response to the prompt, enter the destination UNIX image filename, and press Enter.

This is the name of the image file on the router, not the full pathname of the image on the CD-ROM attached to the PC. Refer to Table 3 for the UNIX image filename.

During the transfer process, the software displays messages indicating that it has accessed the file you have specified and is loading it.

Step 14   Enter yes in response to the prompt asking if you want to erase the existing image resident in the router Flash memory before copying the new one.

Erase flash device before writing? [confirm] yes

The entire copying process takes several minutes and differs from network to network.

The exclamation point (!) indicates that the copy process is taking place. Each exclamation point (!) indicates that ten packets have been transferred successfully. A checksum verification of the image occurs after the image is written to Flash memory.

Step 15   Enter the following commands to reset the configuration register to 0x2102:

Step 16   Enter the reload command to reload the router:

After reload is complete, the router should be running the required Cisco IOS image. Use the show version command to verify.
