1. Use Table 1, "Cisco 1700 Series Default Memory and Upgrade Options," for the feature set memory requirements, factory-default memory, and available memory upgrades for your router.

2. Use Table 2, "Feature Pack Product Numbers Quick-Reference List," to identify the software image you want to load.

3. Use Table 3, "Cisco 1700 Series Feature Packs," to identify your feature pack and the memory required for your feature set, based on the image you load.

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

Product Numbers Quick-Reference List

Feature Pack Overview Table

Feature Set Tables

The Cisco IOS software is packaged in feature sets consisting of software images—depending on the platform. Each feature set contains a specific set of Cisco IOS features.

The following list shows which feature sets are supported on the Cisco 1700 series routers. These feature sets only apply to Cisco IOS Release 12.0(3)T:

• IP

• IP Plus

• IP/Firewall

• IP Plus 40

• IP Plus 56

• IP Plus IPSEC 56

• IP Plus IPSEC 3DES

• IP/IPX/AT/IBM/Firewall Plus IPSEC 56

• IP/IPX/AT/IBM/Firewall Plus 3DES

Caution Cisco IOS images with strong encryption (including, but not limited to, 56-bit data encryption feature sets) are subject to United States government export controls and limited distribution. Images to be installed outside the United States require an export license. Customer orders may be denied or subject to delay because of United States government regulations. Contact your sales representative or distributor for more information, or send an e-mail to export@cisco.com.

Table 4 and Table 5 list the features and feature sets supported by the Cisco 1700 series routers in Cisco IOS Release 12.0(3)T and use the following conventions to identify features:

• Yes—The feature is supported in the software image.

• No—The feature is not supported in the software image.

Installation Notes

This section describes the following topics:

• Image Installation Tips and Troubleshooting When Using RSL

• Alternatives to RSL

Image Installation Tips and Troubleshooting When Using RSL

Image Installation Tips

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

• If you are loading software on a preconfigured router, save the router configuration file on your PC before running RSL.

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

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

• 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

  • media-type aui

Recovering From a Connection Error

If any of the following elements apply to your installation, modify the Short Timeout value from the Options dialog box in RSL:

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

• You are connecting to a Cisco AS5200 access server.

• You see the following error message:

  "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 are connecting to a Cisco AS5200, increase the Short Timeout value to 60 seconds. The Cisco AS5200 requires up to 45 seconds to write a configuration to nonvolatile random-access memory (NVRAM) due to the number of interfaces the it must check during this process.

If you are connecting to any other router or access server, increase the Short Timeout to a value over 25 seconds.

Restoring the Startup Configuration

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

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

Alternatives to RSL

RSL is designed to work with a PC running Microsoft Windows 95 and is the recommended method for downloading software to the router; however, two alternatives are available for installing router software:

• Installing the Router Software by Using the Console or Auxiliary Port

• Installing the Router Software by Using a TFTP Server Application

Installing the Router Software by 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 1700 series router:

Installing the Router Software by Using a TFTP Server Application

Use this TFTP server application method as an alternative method to install the router software from the CD-ROM. You can perform this procedure by 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. If you are using a PC running Windows 95, you can use RSL or the TFTP server included on the feature pack CD-ROM to install the router software. For other operating systems, a number of TFTP or rcp applications are available from independent software vendors or as shareware on the World Wide Web.

Step 2   Start the TFTP server application on the PC 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, select Settings to display a panel. To configure the local PC as a server, select the Server checkbox.

Select a root directory where 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:

• 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 10, you remain connected to the router.

• Establish a Telnet session from the PC to the router. If you choose to use Telnet, your connection to the router will be lost when it is reloaded..

  Caution Make sure that your PC is set up to communicate with the connected device through its network port.

Step 5   Connect your PC's LAN port to the corresponding LAN port on the router. If you are making a direct connection to the router via Ethernet or Fast Ethernet, use an Ethernet crossover cable. If connecting to the router via an Ethernet or Fast Ethernet hub or Token Ring MAU (hub), use straight-through cable.

---

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

---

Step 6   At the prompt, enter the IP address of your PC, as shown in the following example:

This example specifies the DOS image name of the IP feature set for Cisco 1700 series routers (as shown in Table 3 in the section, "Feature Pack Overview Table").

Step 8   At 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 in the "Feature Pack Overview Table" section 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 9   At the prompt, enter yes 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.

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 10   Enter the reload command to reload the router:
