Introduction

This section explains how to use this document, describes feature pack components, and has tables that define the aspects of a feature pack.

How to Use These Release Notes

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

1. Use Table 1, "Feature Pack Product Numbers Quick-Reference List," to identify the software image you want to load.

2. Use Table 2, "Cisco Feature Pack Image Filenames and Memory Requirements," to identify your feature pack and the memory required for your feature set, based on the image you load.

3. Use Table 3, "Feature List by Feature Set for the Cisco 2600 Series Part 1 of 2," and Table 4, "Feature List by Feature Set for the Cisco 2600 Series Part 2 of 2," to identify which features are supported in a feature set image.

4. Use Table 5, "Cisco 2600 Series Default Memory and Upgrade Options," to check the memory required for your feature set, determine the factory-default memory on the router, and view the available memory upgrades.

What Is a Feature Pack?

This section describes:

• Feature Pack Components

• Product Numbers Quick-Reference List

• Feature Pack Overview Table

• Feature Set Tables

Feature Pack Components

A feature pack is a small box that contains the following items:

• CD-ROM with the following software:

  • Cisco IOS feature set software images that can include bundled modem firmware

  • Router Software Loader (RSL) program (a Windows 95 application)

  • Trivial File Transfer Protocol (TFTP) server application (for Windows 95 only)

• Getting Started with the Router Software Loader CD booklet

• Release notes that include alternatives to using the RSL for loading software images onto a router (this document)

• Software license for using Cisco software in object code form on a single access server or router

• Cisco Documentation CD-ROM that contains all Cisco documentation

The heart of a feature pack is the CD-ROM that contains software images and the Router Software Loader (RSL), which is a Windows 95 application that loads an image onto an access server or router. 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 the 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.

To determine the version of Cisco IOS software currently running on a Cisco 2600 router, log into the router and use the show version EXEC command. The following is sample output from the show version command. The version number is indicated on the second line as shown below:

Cisco Internetwork Operating System Software 
IOS (tm) 2600 Software (c2600-is-mz), Version 12.0(2)XD, RELEASE SOFTWARE
 

Additional command output lines include more information, such as processor revision numbers, memory amounts, hardware IDs, and partition information.

Installation Notes

This section provides solutions to problems you might encounter when using the RSL to load Cisco IOS software on a router. It also includes instructions on installing the software using the console or auxiliary port or a TFTP server.

Installing Software Images Using RSL

This section describes some solutions to problems you might encounter when using the 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 access server:

"Failed to configure the router to enable the Cisco IOS software image and configuration file upload and download operations. You may want to check the router to make sure that the selected interface exists."
 

If you encounter this message, try increasing the Short Timeout value in the Options dialog box from 25 seconds, especially if one of the following situations applies:

• You are connecting to an access server that has a large configuration file.

• You are connecting to a Cisco AS5200 access server. A Cisco AS5200 requires up to 45 seconds to write a configuration to nonvolatile random-access memory (NVRAM), due to the amount of interfaces that must be checked during this process. Increase the Short Timeout value to 60 seconds.

• You are connection to a Cisco MC3810 multiservice access concentrator. A Cisco MC3810 requires up to 45 seconds to write a configuration to nonvolatile random-access memory (NVRAM) due to the amount of interfaces that must be checked during this process. Increase the Short Timeout value to 60 seconds.

Restoring the Startup Configuration

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

Step 1 Ensure that all cables are properly attached to both the router and the PC.

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

Helpful Hints

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

• If you have added any static entries to the PC Address Resolution Protocol (ARP) table, one or more of them might be deleted by the RSL. You need to manually re-enter any deleted entries in the PC ARP table.

• If the router's running configuration at connection time is not the same as its startup configuration, the exact configuration is not restored. Any changes that you have made since the last time a copy running-config startup-config or write memory command was entered are lost.

• The RSL restores the router's startup configuration, but some running configuration commands are not restored. To restore the exact running configuration, reboot the router. The following interface configuration commands are not restored to the running configuration: no shutdown, no ringspeed, and media-type aui.

Alternatives to the 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:

• Using the console or auxiliary port

• Using a TFTP server application

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 onto the router.

The following example shows how to use the copy xmodem flash command on a Cisco 2600 series router.

Router# copy xmodem flash

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 1 Install any TFTP server application on the PC. (A PC application is included on the feature pack CD-ROM for Microsoft Windows 95 only.)

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 that includes a checkbox beside the word Server, which allows you to configure the local PC as a server.

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.

Caution Make sure you set up your local PC as a TFTP server. If you overlook this step, you cannot perform the copy procedure. This reminder also applies if you are using rcp instead of TFTP.

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:

• Connect the PC com port to the router console port.

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.)

• Establish a Telnet session from the PC to the router.

Caution Make sure your PC is set up to communicate with the 10BaseT Ethernet port on 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, a 100BaseT hub, or a Token Ring MAU.

---

Note We recommend that you back up the router configuration before upgrading the router software.

---

Step 6 Enter yes when asked if the system configuration has been modified:

# System configuration has been modified. Save? yes
 

Step 7 Enter yes when asked to confirm the reload:

Proceed with reload? [confirm] yes

Wait for the router to reload.

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

Password: <password>
 

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

Router(boot)> enable
Password: <password>
 

Step 10 At the router prompt, enter the following command to copy the new software image from the PC CD-ROM drive to the router:

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

Source file name? il202d.bin
 

This example specifies the DOS image name of the IP feature set for Cisco 2600 series routers (as shown in Table 2 in the "Cisco 2600 Series Feature Packs" section).

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

This is the name of the image file on the router, not the full path of the image on the CD-ROM attached to the PC. Refer to Table 2 in the section, "Cisco 2600 Series Feature Packs" for the UNIX image filename.

Destination file name [il202d.bin]? c2600-i-mz.120-2.xd
 

Step 14 Enter yes in response to the prompt asking if you want to erase the existing image copy 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.

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

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:

Router(boot)(config)# config terminal
Router(boot)(config)# config-reg 0x2102
Router(boot)(config)# end
 

Step 16 Enter the reload command to reload the router:

Router# reload
