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.

For a summary of which feature sets are supported on the Cisco 800 series, see the previous "Feature Pack Overview Table" section.

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 limited distribution. Strong encryption images to be installed outside the United States are likely to require an export license. Customer orders may be denied or subject to delay due to United States government regulations. When applicable, purchaser/user must obtain local import and use authorizations for all encryption strengths. Please contact your sales representative or distributor for more information, or send an e-mail to export@cisco.com.

Table 5, Table 6 and Table 7 list the features and feature sets supported by the Cisco 800 series in Cisco IOS Release 12.0(7)T and use the following conventions to identify features:

The Cisco 800 series routers also support the features listed in Table 6.

Installation Notes

This section describes the following topics:

Image Installation Tips and Troubleshooting When Using RSL

Image Installation Tips

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

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:

"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.

Note   If you change the timeout value, you must do so before connecting to the router, or the new value will not be used. Also, increasing the Short Timeout value can increase the time it takes for RSL to connect to the target router.

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.

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.

Step 7   Exit RSL.

Note   In the steps above, the router configuration register (config-register 0xnnnn) is not restored.

Note   If you press Ctrl-Alt-Delete to quit RSL, the router configuration and the configuration register are not restored. However, the configuration file is not deleted from the PC. To restore the configuration file, follow the steps above, beginning with Step 2.

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

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 800 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.

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

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).

Caution   Make sure you set up your local PC as a TFTP server. If you do not, you cannot perform the copy procedure. This caution 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:

This is the recommended method. When you reload the router with the new image in Step 10, you remain connected to the router.

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:

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 7   At the prompt, enter the filename of the Cisco IOS Release 12.0 image to be copied to the router, as shown in the following example:

This example specifies the DOS image name of the IP feature set for Cisco 800 series routers (as shown in Table 4 in the "Feature Pack Overview Table" section).

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 4 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:

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