Cisco Feature Packs and Memory Requirements

This section explains the following:

• What Is a Feature Pack?
  
  
• Cisco IOS Release 11.2(12)P Feature Pack Descriptions and Memory Requirements
  
  

What Is a Feature Pack?

The heart of a Cisco IOS software feature pack is a CD-ROM that contains a software image and Router Software Loader (RSL), a Windows 95 application that loads the image onto the access server/router. Each Cisco IOS Release 11.2 feature pack CD-ROM contains one feature set. For users without Windows 95, images can also be loaded with a Trivial File Transfer Protocol (TFTP) server application, as explained in these release notes.

Each Cisco IOS Release 11.2 software feature pack box contains the following:

• CD-ROM with the following software:
  
  
• Feature set software image that includes bundled modem firmware
  
  
• RSL program (Windows 95 application)
  
  
• TFTP server application (Windows 95 application)
  
  
• Instruction booklet for using RSL
  
  
• Release notes (this document), which includes instructions for using a TFTP server application on a system not running Windows 95 Software license, for using Cisco software in object code form on a single access server or router
  
  
• Cisco Documentation CD-ROM, which contains all Cisco IOS software documentation
  
  

Cisco IOS Release 11.2(12)P Feature Pack Descriptions and Memory Requirements

This section includes two tables:

• Table 1—Describes each feature pack image, including a brief description of each feature set, the images' UNIX and DOS filenames, and memory requirements.
  
  
• Table 2—Describes the factory default available memory and the possible memory upgrades for the Cisco 3600 series routers.
  
  

You can use Table 1 to identify the memory required for your configuration based on the image you run. You can then check this against Table 2 to determine how much memory is available on the access server as the factory default and the upgrades that you can obtain to satisfy your requirements.

Cisco IOS Feature Sets for the Cisco 3600 Series Routers

The Cisco IOS software is packaged into "feature sets" (also called "software images"). There are many different feature sets available, and each feature set contains a specific subset of Cisco IOS features. The feature set matrix is used to see the overall feature set organization.

Feature Set Matrix

The feature set matrix (see Table 2) shows the new feature set organization and lists which feature sets are available on the Cisco 3600 series for Cisco IOS Release 11.2(12)P. The matrix uses the following terms:

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.

Feature Set Table

To determine what features are available with each feature set, see Table 3. The table summarizes what features you can use when running a specific feature set on the Cisco 3600 series for Cisco IOS Release 11.2(12)P. The feature set table uses the following symbols:

Modem Code Alert

By default, the MICA modems installed on the 3600 use the modem portware that is bundled with the Cisco IOS software image. Unless you are familiar with the Cisco MICA portware, we recommend that you use the default firmware and do not attempt to download another version.

If you do choose to override the firmware and portware selected by Cisco IOS software, the Flash memory of your router might contain modem code files that should be saved and restored before downloading the new image. Before the image download begins, the Router Software Loader (RSL) will display the Flash Copy Options dialog box that will allow you to select which files to back up and restore. By default, RSL will back up all files in the selected Flash memory partition, and restore the files you select.

If you want to verify that you are running the latest modem code, use the show modem version command to display the current version. Then compare that version to the modem code files available on the feature pack CD and on Cisco Connection Online (CCO).

Modem Code Information

If you are running Microsoft Windows 95 on a PC, we recommend using the RSL to download modem code. For detailed steps, refer to the RSL online help topic "Downloading Modem Files." If you are running Windows NT, UNIX, or Macintosh, use TFTP or rcp to download modem code. TFTP server instructions are in the online document titled "Another Way to Download Modem Code."

Both RSL and TFTP instructions are available from the Software Center at the following URL:
http://www.cisco.com/public/sw-center/sw-access.shtml
Click on the link Modem Software Upgrade for Cisco 2-tier Channel Customer. Follow the steps to download the new modem code.

See the sections "Cisco Connection Online" and "Documentation CD-ROM" for information on accessing customer documentation.

Installing Software Images Using RSL

The Router Software Loader (RSL) application contained on the feature pack CD-ROM is designed to work with a PC running Microsoft Windows 95. Refer to the booklet included with the CD-ROM for instructions to install the software images.

This section describes several solutions to problems you might encounter when using RSL. These solutions are additions to the RSL online help.

Recovering from a Connection Error

This installation tip provides a possible recovery solution in the event that 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 router:

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 a router 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, 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 RSL and connect 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 connected, select Download Router Configuration in the Router Software Loader dialog box.

Step 6   Select the appropriate file, and click Copy configuration to the router's nonvolatile memory.

The router should now contain the startup configuration it had before the initial RSL connection. You can now exit 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's Address Resolution Protocol (ARP) table, one of them might be deleted by RSL. This entry will need to be manually reentered into the PC's ARP table.
  
  
• If the router's running configuration at connection time is not the same as the router's startup configuration, the exact configuration will not be restored. Any changes that you have made since the last time a copy running-config startup-config or write memory command was entered will be lost.
  
  
• RSL will restore the router's running configuration, but some configuration commands will not be restored. However, the startup configuration will be correct. You can restore the exact running configuration by rebooting the router. Commands not restored to the running configuration include the following interface configuration commands: no shutdown, no ringspeed, and media-type aui.
  
  

Alternatives to 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:

• Use the console or auxiliary port
  
  
• Use 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 3600 series router.

Installing Software Images Using a TFTP Server Application

The Router Software Loader application contained on the feature pack CD-ROM is designed to work with a PC running Microsoft Windows 95. The booklet included with the CD-ROM explains how to perform this simple and recommended install process. However, an alternative is available using a TFTP server application to install router software.

This section explains how to use a TFTP server application 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 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. You can use the RSL or the TFTP server included on the feature pack CD-ROM to install the 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 as shareware from public sources on the World Wide Web.

Installation Process

This section describes how to use TFTP on a PC to install the router software.

Step 1   Install any TFTP server application on the PC. (The PC application included on the feature pack CD-ROM is 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, click 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.

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 also applies if you are using rcp instead of TFTP.

Step 4   Establish a console session from your local PC (which is now configured as a TFTP server) to the 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 12, 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.
  
  

Step 5   Connect your PC Ethernet port to the router Ethernet port. Use an Ethernet crossover cable.

---

Note Use straight-through cables if you are connecting via a 10BaseT hub or a 100BaseT hub.

---

For systems without a LAN interface, make sure that the router and the PC have IP connectivity through the available interface (that is, the router and PC can ping each other with IP traffic).

---

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

---

Step 6   Enter the following commands to enter enable mode and copy the new software image from the PC (set up as a TFTP server) to the router:

(boot)# 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 7   When prompted, enter the IP address of your PC, as in the following example:

Address or name of remote host [255.255.255.255]? 172.16.1.1

This is the IP address of your local PC, not that of the router.

Step 8   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? 80180812.bin

This example specifies the DOS image name of the IP feature set for a Cisco 3600 router, as listed in Table 1.

Step 9   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 path name of the image on the CD-ROM attached to the PC. Refer to Table 1 in the section, "Cisco Feature Packs and Memory Requirements" for the UNIX image filename.

Step 10   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.

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

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 11   Enter the following commands to change the config-reg to 0x2102. This will force the router to reload to the image running from Flash memory.

Step 12   Enter the reload command to reload the router:

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