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.

For a summary of which feature sets are supported on the Cisco 1000 series, see the previous "Feature Pack Overview Table" section.

Table 5 and Table 6 list the features and feature sets supported by the Cisco 1003 & 1004 and Cisco 1005 routers in Cisco IOS Release 12.0, respectively. 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.
  
  
• In—The number in the "In" column indicates the Cisco IOS release in which the feature was introduced. For example, (5) means a feature was introduced in Release 12.0(5)T. If a cell in this column is empty, the feature was included in the initial base release.
  
  

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.

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.

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.

Loading Images on CiscoPro Routers When Using RSL

Prerequisites

By default, non-CiscoPro software images cannot be loaded on CiscoPro routers; however, RSL has a utility to permanently upgrade CiscoPro routers so they can accept the Cisco IOS Release 12.0 images.

When a CiscoPro router is upgraded, the Simple Network Management Protocol (SNMP) SysObjectID MIB value (used for network management), is changed to that of a normal Cisco router. The software banner also changes and no longer identifies the upgraded platform as a CiscoPro product.

Note   After this upgrade, CiscoVision will no longer recognize your router.

If you choose this permanent upgrade, use the appropriate version of CiscoWorks for Windows below to replace CiscoVision as the network manager:

• CPW-CVCW-U to upgrade CiscoVision to CiscoWorks Windows (managing up to 50 nodes).
  
  
• CPW-CVCW-ENT-U to upgrade CiscoVision to CiscoWorks Windows (managing up to 500 nodes).
  
  

Note   For general information about Cisco Systems, Cisco products, or upgrades, contact 800 553-6387, 408 526-7208, or cs-rep@cisco.com.

Upgrading Your CiscoPro Router

Note   The following steps are only necessary for the CiscoPro CPA1000, CPA1600, CPA2500 and CPA4500 platforms. Other CiscoPro platforms can be upgraded by simply loading a non-CiscoPro software image.

To upgrade your CiscoPro CPA1000, CPA1600, CPA2500 or CPA3600 router, follow these steps:

A message box tells you that the router requires a permanent upgrade to load the image.

Step 2   At the prompt, enter yes to indicate that you do want RSL to upgrade your CiscoPro router and continue loading the selected image.

RSL downloads, performs the upgrade, reboots the router, and displays a message to confirm the upgrade.

Note   The Cisco 1000 series upgrade utility filename is cpa1000-upgrade-l.120-8. The upgrade utility is a special file—not a Cisco IOS run-time image, and must be located in the Images directory. If it is not, the upgrade utility informs you that the image is not present.

Step 3   At the prompt, confirm the upgrade message. RSL then downloads the selected image.

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
  
  
• Installing the Router Software by Using a TFTP Server Application
  
  

Note   The sample prompts and output shown in the following sections may not be identical to the prompts displayed on the router console.

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 1000 series router:

Router# copy xmodem flash

                               **** WARNING ****

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:

• 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 20, 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   If you are not upgrading a CiscoPro CPA1000 router, skip to Step 15.

Step 7   At the prompt, enter the following command to copy the router upgrade utility from the PC CD-ROM drive to the router:

Router **** WARNING **** copy tftp flash

Note   If you are using rcp, enter copy rcp flash instead.

Step 8   At the prompt, enter the IP address of your PC, as shown in the following example:

x/ymodem is a slow transfer protocol limited to the current speed 131.108.1.1

This is the IP address of your local PC—not the router. (Note that you can obtain your PC IP address from the DOS prompt in the Windows directory by entering winipcfg, as follows: settings of the auxiliary/console ports. The use of the auxilary winipcfg.)

Step 9   At the prompt, enter the filename of the image to be copied to the router, as shown in the following example:

port for this download is strongly recommended. cpa1000-upgrade-l.120-8

Note   The upgrade image file on the Feature Pack CD has a long filename (cpa1000-upgrade-l.120-8); note that DOS displays it in 8.3 format as cpa1000~8. The upgrade utility is a special file—not a Cisco IOS run-time image.

Step 10   At the following prompt, enter the destination filename and press Enter.

During the course of the download no exec input/output will be cpa1000-upgrade-l.120-8

(This is the name of the image file on the router—not the full pathname of the image on the PC CD-ROM.)

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

If the software cannot find the file, check the following:

• The filename is correct.
  
  
• The TFTP server is enabled.
  
  
• The correct root directory is selected.
  
  
• There is IP connectivity between the router and TFTP server.
  
  

If the software still cannot find the file, create a temporary directory called "C:\temp," and copy the CiscoPro upgrade file into the directory. Select the C:\temp directory as the root directory.

Step 11   To erase the existing image in the router Flash memory before copying the new one, enter yes:

available. 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. If you see three or more periods (...), the transfer may have failed. If so, use the ping command to check IP connectivity between the router and TFTP server.

Step 12   Enter the reload command to reload the router:

Router# reload

Do not save the configuration.

After the reload is complete, your CiscoPro router has been upgraded to a Cisco Enterprise router. Because the original Cisco IOS image that resided in Flash memory was erased during the upgrade process, the router is now running in bootstrap mode.

Step 13   At the prompt, enter your password:

Password: <password>
 

Step 14   At the prompt, enter enable; then enter your password:

Router# enable

Password: <password>
 

Step 15   At the prompt, enter the following command to copy the new software image from the PC CD-ROM drive to the router:

Router# copy tftp flash

In the next series of steps, you download the Cisco IOS Release 12.0 images that you want installed on your router.

Step 16   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 17   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:

Source file name? 80153209.bin

 

This example specifies the DOS image name of the IP feature set for Cisco 1000 series routers (as shown in Table 4 in the "Feature Pack Overview Table" section).

Step 18   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.

Destination file name [80153209.bin]? c1000-y-mz

 

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

Step 19   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.

C:\WINDOWS>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.

Caution If you upgraded a CiscoPro CPA1000 router, do not save the configuration when prompted.

Step 20   Enter the reload command to reload the router:

Router# reload 
 

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

Documentation CD-ROM

Cisco documentation and additional literature are available in a CD-ROM package, which ships with your product. The Documentation CD-ROM, a member of the Cisco Connection Family, is updated monthly. Therefore, it might be more current than printed documentation. To order additional copies of the Documentation CD-ROM, contact your local sales representative or call customer service. The CD-ROM package is available as a single package or as an annual subscription. You can also access Cisco documentation on the World Wide Web at http://www.cisco.com, http://www-china.cisco.com, or http://www-europe.cisco.com.

If you are reading Cisco product documentation on the World Wide Web, you can submit comments electronically. Click Feedback in the toolbar and select Documentation. After you complete the form, click Submit to send it to Cisco. We appreciate your comments.
