4. Use Table 5, "Cisco 3600 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 Table

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 the 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.

Product Numbers Quick-Reference List

Table 1 lists the Cisco product numbers of the feature packs supported in this release.

Feature Pack Overview Table

Table 2 identifies each feature pack as specified on the router software CD-ROM label, describes the feature sets in each feature pack, and lists the UNIX and DOS filenames of the images, memory requirements, and the RSL installer description.

Feature Set Table

The Cisco IOS software is packaged into feature sets (also called images). Many different feature sets are available, and each feature set contains a specific subset of Cisco IOS features. The following conventions are used to identify feature sets:

• Plus---Value-added feature set with additional features.

• Plus 40---Value-added feature set with additional features, including 40-bit data encryption.

• Plus 56---Value-added feature set with additional features, 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 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 which feature sets are supported on the Cisco 3600 series routers. These feature sets only apply to Cisco IOS Release 11.3 T:

Software Compatibility

The feature packs described in these release notes contain Cisco IOS Release 11.3(6)T software images, some earlier images, and the Router Software Loader (RSL) Version 7.2. Before running the RSL, read the "Installing Software Images Using the RSL" section.

Determining Your Software Release

To view the version of Cisco IOS software that is running on your Cisco 3600 series router, log in to the router, and enter the show version user EXEC command:

The output begins similar to the following. The Cisco IOS version appears in the second line.

The output includes more information including processor revision numbers, memory amounts, hardware IDs, and partition information.

Modem Code Alert

By default, the MICA modems installed on the Cisco 3600 series routers use the modem portware that is bundled with the Cisco IOS software image. Unless you are familiar with the Cisco MICA portware, we recommend that you use the default firmware and do not attempt to download another version.

If you do choose to override the firmware and portware selected by Cisco IOS software, the Flash memory of your router might contain modem code files that should be saved and restored before downloading the new image. Before the image download begins, the Router Software Loader (RSL) will display the Flash Copy Options dialog box, which will allow you to select which files to back up and restore. By default, RSL will back up all files in the selected Flash memory partition and restore the files you select.

If you want to verify that you are running the latest modem code, use the show modem version command to display the current version. Then compare that version to the modem code files available on the feature pack CD-ROM and on Cisco Connection Online (CCO).

Modem Code Information

If you are running Microsoft Windows 95 on a PC, we recommend using the RSL to download modem code. For detailed steps, refer to the RSL online help topic, "Downloading Modem Files." If you are running Windows NT, UNIX, or Macintosh, use TFTP or remote copy protocol (rcp) to download modem code. TFTP server instructions are in the online document titled Another Way to Download Modem Code.

Both RSL and TFTP instructions are available from the Software Center at the following URL:

http://www.cisco.com/public/sw-center/sw-access.shtml

Click on the link, Router Software Loader (RSL). Follow the steps to download the new modem code.

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 describes special cases that might require you to load Cisco IOS software on a CiscoPro router or to use an alternative to the RSL.

Installing Software Images Using the RSL

The Router Software Loader (RSL) Version 7.2 supports the following Cisco 3600 series routers:

• CiscoPro CPA3620 and CPA3640

• Cisco 3620 and 3640

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 router:

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 a router 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 connecting 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 reenter 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.

Loading Cisco IOS Release 11.3 Software on CiscoPro Routers

The RSL has an upgrade utility to permanently modify a CiscoPro router so that it accepts Cisco IOS Release 11.3 software images. The utility changes the router SysObjectID Simple Network Management Protocol (SNMP) MIB value (used for network management) to that of a Cisco router. The software banner also changes and no longer identifies the router as a CiscoPro product.

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 3600 series router:

Installing the Router Software Using a TFTP Server Application

This section explains how to use a TFTP server application 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 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. You can use the RSL or the TFTP server included on the feature pack CD-ROM to install the 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 as shareware from public sources on the World Wide Web.

Step 1 Install any TFTP server application on the PC. (The PC application included on the feature pack CD-ROM is 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. To configure the local PC as a server, click this 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.

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 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 12, 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.

Step 5 Connect your PC Ethernet port to the router Ethernet port. Use an Ethernet crossover cable.

---

Note Use straight-through cables if you are connecting via a 10BaseT hub or a 100BaseT hub.

---

For systems without a LAN interface, make sure that the router and the PC have IP connectivity through the available interface (that is, the router and PC can ping each other with IP traffic).

---

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

---

Step 6 Enter the following commands to enter enable mode and copy the new software image from the PC (set up as a TFTP server) to the router:

Router> enable Password: <password> Router#

Router# copy tftp flash

In the next series of steps, you download the Cisco IOS Release 11.3 images that you want installed on your router.

Step 7 When prompted, enter the IP address of your PC, as in the following example:

Address or name of remote host [255.255.255.255]? 172.16.1.1

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

Step 8 When prompted, enter the filename of the Cisco IOS Release 11.3 image to be copied to the router, as in the following example:

Source file name? 80235906.bin

This example specifies the DOS image name of the IP feature set for a Cisco 3600 series router, as listed in Table 2.

Step 9 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 path name of the image on the CD-ROM attached to the PC. Refer to Table 2 in the "Cisco Feature Pack Image Filenames and Memory Requirements" section for the UNIX image filename.

Destination file name [80235906.bin]? c3640-i-mz.113-6.T

Step 10 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 11 Enter the following commands to change the configuration register to 0x2102. This will force the router to reload to the image running from Flash memory.

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

Step 12 Enter the reload command to reload the router:
