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. Release 12.1(1)XC supports the same feature sets as Releases 12.1 and 12.1 T, but Release 12.1(1)XC can include new features supported by the Cisco 1700 series routers. Table 5 lists the feature sets supported by the Cisco 1700 series routers.

1The number in the "In" column indicates the Cisco IOS release in which the feature was introduced. For example, 12.0(3)T means a feature was introduced in Release 12.0(3)T. If a cell in this column is empty, the feature was included in the initial base release. 2This set of features is provided in the Triple DES (3DES) Encryption data encryption feature sets. 3This image is deferred in Releases 12.1(1), 12.1(1)T, and 12.1(1)XC.

---

Caution   Cisco IOS images with strong encryption (including, but not limited to 168-bit (3DES) data encryption feature sets) are subject to United States government export controls and have limited distribution. Strong encryption images to be installed outside the United States may require an export license. Customer orders may be denied or subject to delay due to United States government regulations. When applicable, the purchaser or the user must obtain local import and use authorizations for all encryption strengths. Contact your sales representative or distributor for more information, or send an e-mail to export@cisco.com.

---

Table 6 lists the features and feature sets supported by the Cisco 1700 series routers in Cisco IOS Release 12.1(1)XC. Table 7 lists the features and feature sets supported by the Cisco 1750 routers in Cisco IOS Release 12.1(1)XC. Both tables use the following conventions:

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

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

Note   These feature set tables only contain a selected list of features. These tables are not cumulative—nor do they list all the features in each image.

Installation Notes

This section describes the following topics:

• Installing Software Images Using RSL

• Alternatives to the RSL

Installing Software Images Using RSL

This section describes some solutions to problems you might encounter when installing software images 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 access server or 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:

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

• 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.

Note   Increasing the Short Timeout value might increase the time it takes for RSL to connect to the target access server.

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 radio button beside Copy configuration to the router nonvolatile memory.

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

In the previous situation, the router configuration register (config-register 0xnnnn) is not restored.

---

Note   If you press Ctrl-Alt-Delete to terminate the RSL, the router configuration and configuration register are not restored. However, in this case, the configuration file is not deleted from the PC, so you can restore it using the previous steps, beginning with Step 2.

---

---

Installation Tips

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 transfer takes place only on the port at which you enter the command. If you download via the console, all console output is discarded for the duration of the transfer. You can only download files to the router; you cannot copy files from the router. Cisco recommends using the auxiliary port for this type of software download. The auxiliary port has hardware flow control and full modem control. In addition, the transfer does not occupy the system console so it is free for other uses.

The following example shows how to use the copy xmodem flash command on a Cisco 1700 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 a rcp server. Only use the RSL or the TFTP server included on the feature pack CD-ROM to install the router software 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.

Note   To use an rcp application, follow the same procedure below, substituting "rcp" for "TFTP" and using the copy rcp flash command instead of the copy tftp flash command.

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).

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 applies to both TFTP and rcp.

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 or a 100BaseT hub.

Note   We recommend 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   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:

This example specifies the DOS image name of the IP feature set for Cisco 1700 routers (as shown in Table 3 and Table 4 in the section, "Feature Pack Overview Table").

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 and Table 4 in the section, "Feature Pack Overview Table" 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 copy resident in the router Flash memory before copying the new one.

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:
