How to Use These Release Notes

The tables in these release notes contain details about the Cisco feature packs. Use these tables to perform the following tasks before loading a software image onto a router:

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
  
  
• 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 following: 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 4500 and Cisco 4700 series routers and access servers. These feature sets only apply to Cisco IOS Release 11.2 P:

• IP
  
  
• IP Plus
  
  
• IP Plus 40
  
  
• IP Plus 56
  
  
• IP/IPX/AT/DEC
  
  
• IP/IPX/AT/DEC Plus 40
  
  
• IP/IPX/AT/DEC Plus 56
  
  
• Enterprise
  
  
• Enterprise Plus
  
  
• Enterprise Plus 40
  
  
• Enterprise Plus 56
  
  

To determine what features are available with each feature set (software image), see Table 3. The table summarizes the features you can use when running a specific feature set on the Cisco 4500 and Cisco 4700 routers for Cisco IOS Release 11.2 P. Table 3 uses these terms:

System Requirements

This section describes the following:

• Memory Requirements
  
  
• Hardware Supported
  
  
• Software Compatibility

Memory Requirements

Table 4 lists the memory delivered by default and the available memory upgrades.

Hardware Supported

The Router Software Loader (RSL) version 7.0 supports many Cisco routers. Specific to the Cisco 4000 series routers, RSL 7.0 supports:

• CiscoPro CPA4500 and CPA4700
  
  
• Cisco 4500 and 4700
  
  

Software Compatibility

The feature packs described in these release notes contain Cisco IOS Release 11.2(14)P software images, some earlier images, and the Router Software Loader (RSL) Version 7.0. 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 4000 series router, log in to the router, and enter the show version user EXEC command:

router> show version
 

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

Cisco Internetwork Operating System Software 
IOS (tm) 4000 Software (C4000-BNR2SY-L), Version 11.2(14)P, RELEASE SOFTWARE
 

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

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

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 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:

"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 encounter this message, try increasing the Short Timeout value, which is set to 25 seconds, in the Options dialog box, especially if one of the following situations applies:

• 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.
  
  

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.

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.

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 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.
  
  

Loading Cisco IOS Release 11.2 Software on CiscoPro Routers

The RSL has an upgrade utility to permanently modify a CiscoPro router so that it accepts Cisco IOS Release 11.2 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.

If you select a Cisco IOS Release 11.2 image from the image list and are connected to a CiscoPro CPA 4000 series router, a message box tells you that the router requires a permanent upgrade to load this image. You can either select yes to have the RSL upgrade the router and continue loading the selected image or select no to cancel the load operation.

After you select yes, the RSL utility downloads, performs the upgrade, reboots the router, and issues a message to confirm the upgrade. Confirm this message. The RSL then downloads the selected image.

The upgrade utility must be located in the Images directory. If it is not, the upgrade utility informs you that the image is not present.

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 4000 series router:

Router# copy xmodem flash
                               **** WARNING ****
       x/ymodem is a slow transfer protocol limited to the current speed
       settings of the auxiliary/console ports. The use of the auxilary
       port for this download is strongly recommended.

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 an rcp server. Use the RSL or the TFTP server included on the feature pack CD-ROM to install the router 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 available as shareware from public sources on the World Wide Web.

Step 1 Install any TFTP server application on the PC. (A PC application is included on the feature pack CD-ROM 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 check box beside the word Server. To configure the local PC as a server, select this check box.

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.

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 24, 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.

Step 6 Enter the following commands to set the configuration register to 0x2101 and reload to the bootstrap image:

Router# configure terminal
Router(config)# config-reg 0x2101
Router(config)# end
Router# reload
 

Step 7 Enter yes in response to the prompt asking if the system configuration has been modified:

# System configuration has been modified. Save? yes
 

Step 8 If the password prompt appears, enter the password.

Password: <password>
 

Step 9 At the router prompt, enter enable and then the password:

Router(boot)> enable
Password: <password>
 

Step 10 At the router prompt, enter the following command to copy the router upgrade utility from the PC CD-ROM drive to the router:

Router(boot)# copy tftp flash

Step 11 When prompted, enter the IP address of your PC, as 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 the router. (Note that you can obtain your PC IP address from the DOS prompt in the windows directory by entering winipcfg, as follows: C:\WINDOWS> winipcfg.)

Step 12 When prompted, enter the filename of the image to be copied to the router as in the following example:

Source file name? cpa4500-i-mz.112-14.P

Step 13 In response to the following prompt, enter the destination filename, and press Enter.

Destination file name [cpa1600-upgrade-l.112-3.P]?
cpa4500-i-mz.112-14.P

(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 file is not found, 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 file is still not found, 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 14 Enter yes in response to the prompt asking if you want to erase the existing image 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. If you see three or more periods (...), the transfer might fail. If the transfer fails, use the ping command to check IP connectivity between the router and TFTP server.

Step 15 Enter the reload command to reload the router:

Router(boot)# reload

Do not save the configuration.

After 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 16 If the password prompt appears, enter the password.

Password: <password>
 

Step 17 At the router prompt, enter enable and then the password:

Router(boot)# enable
Password: <password>
 

Step 18 At the router prompt, enter the following command to copy the new software image from the PC CD-ROM drive to the router:

Router(boot)(config)# copy tftp flash

In the next series of steps, you download the Cisco IOS Release 11.2 images that you want installed on your router.

Step 19 When prompted, enter the IP address of your PC, as 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 20 When prompted, enter the filename of the Cisco IOS Release 11.2 image to be copied to the router, as in the following example:

Source file name? 80137013.bin
 

This example specifies the DOS image name of the IP feature set for Cisco 4000 or 4500 series routers (as shown in Table 2 in the "Feature Pack Overview Table" section).

Step 21 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 2 in the "Feature Pack Overview Table" section for the UNIX image filename.

Destination file name [80137013.bin]? c4500-i-mz.112-14.P
 

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

Step 22 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.

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 23 Enter the following commands to reset the configuration register to 0x2102.

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

Step 24 Enter the reload command to reload the router:

Router# reload 
 

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