What Is a Feature Pack?

The heart of a Cisco IOS software feature pack is a CD-ROM that contains software images and RSL, a Windows 95 application, which loads the images onto the router. Each Cisco IOS Release 11.2 feature pack CD contains feature sets and one bootstrap software image. For users without Windows 95, images can also be loaded with a Trivial File Transfer Protocol (TFTP) server application.

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

• CD-ROM with the following software:

  • Feature set software images

  • Bootstrap software image

  • RSL program (a Windows 95 application)

• Instruction booklet for using RSL

• Release notes (this document), which include 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 router

• Cisco Documentation CD-ROM, which contains all Cisco IOS software documentation

Supported Platforms

RSL 5.0 supports both Cisco and CiscoPro versions of the Cisco 4500 and 4700 routers:

• CiscoPro CPA4500 and CPA4700

• Cisco 4500 and 4700

Loading Cisco IOS Release 11.2 Software on CiscoPro Routers

RSL contains an upgrade utility that permanently modifies a CiscoPro router so that it will accept the Cisco IOS Release 11.2 software images.

The utility changes the router's SysObjectID Simple Network Management Protocol (SNMP) MIB value (used for network management) from CiscoPro to that of a Cisco router. The software banner also changes so that it no longer identifies the router as a CiscoPro product.

Cisco Feature Pack Descriptions

This section describes the Cisco feature packs, listing the software feature sets comprising each pack. You can use this information to identify your feature pack set in conjunction with the corresponding information provided in the table in the section "Cisco IOS Release 11.2 Feature Sets,". The table in that section identifies which features are supported for a feature set on a specific platform.

Software Feature Packs

This section includes two tables: Table 1 identifies each feature pack as specified on the label of the CD containing the router software. It also lists the feature sets comprising the feature pack, giving the UNIX and DOS filenames of the images. The table provides a brief description of each feature set and the router platform on which the feature set runs. Table 1 also identifies the memory required to run each feature set on your specific platform; Table 2 describes the memory delivered by default and the memory upgrades available.

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 router as the factory default and the upgrades that you can obtain to satisfy your requirements.

Memory Recommendations

Table 3 gives memory recommendations for routers based on the purpose for which you use the router. These recommendations are application-specific; they do not correspond to memory requirements given for images shown in Table 1. For example, if your router maintains routing data for more than 50 networks, we recommend 32 MB of main memory even though Table 1 indicates that the image itself requires 16 MB.

You can use the Cisco 4500 or 4700 router for one or more purposes. Refer to the memory recommendations Table 3 gives for single or combined applications. These uses of the router and their recommended memory sizes are not mutually exclusive. For example, if you connect directly to the Internet backbone, we recommend that you have 32 MB of main memory. If you also maintain more than 24 WAN virtual circuits on the same router, we recommend that you have 48 MB of RAM (the sum of recommended memory amounts supporting both applications).

For more comprehensive information on memory recommendations for Cisco routers, go to www.cisco.com, select Products & Ordering, then Product Bulletins. Under "Access Products," select product bulletin #419.

Installation Tips

This section describes several solutions to problems you might encounter when using RSL. These solutions are additions to RSL's 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 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:

"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 a router that has a large configuration file.

• You are connecting to a Cisco AS5200. 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 the radio button beside 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 may be deleted by RSL. This entry will need to be manually re-entered into the PC's ARP table.

• If your router is configured with a boot system flash filename command, where filename is the name of the previous image residing in the first partition of Flash memory, this command must be manually changed to reflect the name of the image that was copied to the router's first Flash memory partition.

• 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.

• If you connect to a router with multiple Flash memory partitions, it will always copy the new image to the first partition and reload to the first partition. This will fail if there is not enough memory in the first partition.

• 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.

Cisco IOS Release 11.2 Feature Sets

Table 4 shows specific features supported for Cisco IOS Release 11.2 on Cisco 4500 and 4700 routers.

The table uses these conventions to identify features:

• Yes: the feature is offered in the basic feature set

• - : the feature is not offered in the feature set

• Plus: the feature is offered only in the Plus feature sets, not in the basic feature set

• Encrypt: the addition of 40-bit (Plus 40) or 56-bit (Plus 56) data encryption feature sets

Cisco IOS images with 40-bit Data Encryption Standard (DES) support can legally be distributed to any party eligible to receive Cisco IOS software. 40-bit DES is not a cryptographically strong solution and should not be used to protect sensitive data.

Cisco IOS images with 56-bit DES are subject to International Traffic in Arms Regulations (ITAR) controls and have a limited distribution. Images to be installed outside the U.S. require an export license. Customer orders may 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.

Back Rev Feature Sets

For a list of features supported by the back rev feature sets, see the release notes available on the Documentation CD-ROM or the World Wide Web (www.cisco.com). See the section "About Cisco IOS Software Electronic Documentation,". For example, to find a feature set list for Cisco IOS Release 11.1(8), locate the Cisco IOS Software Configuration database. Then select Cisco IOS Release 11.1, and then select Release Notes for Cisco IOS Release 11.1.

Installing the Bootstrap System Software Using RSL

You can use RSL to download bootstrap software images to the router's boot Flash memory. In the Router Software Loader dialog box, select the Operations menu, and then Load Bootstrap Software.

This operation is enabled when you connect RSL to the router and the boot Flash memory is detected on the router.

To download a new bootstrap image, select the bootstrap image from the image list. Bootstrap images are in the Boot directory on the feature pack CD. Select the Operations menu, then Load Bootstrap Software. A progress bar will indicate the status of the download operation.

Installing the Router Software Without Using Windows 95

This section describes an alternative method you can use to install the router software from the CD-ROM using a PC running Windows 3.1, a Macintosh, or a UNIX system. The process requires that you first obtain a TFTP application or a remote copy protocol (rcp) application, which you can use to set up your computer as a TFTP server or an rcp server. You can use either the copy tftp flash or copy rcp flash command to download the router software feature sets to the router.

You can load router software with this alternative method in the following circumstances:

• You are not running Windows 95.

• Your router does not contain an Ethernet, Fast Ethernet, or Token Ring interface.

Installation Process for Router Software Feature Sets

This section provides steps that describe how to install the router software feature sets using a Microsoft Windows 3.1 PC with a TFTP server application. You can also set up your Macintosh or UNIX workstation as a TFTP server and follow the same steps.

To install the software using an rcp application, follow the same procedure and substitute rcp for TFTP in the instructions. You must also substitute the copy rcp flash command for the copy tftp flash command in Step 8.

Step 1 Install any TFTP application on the PC. (Not provided by Cisco.)

Step 2 Launch the TFTP application on the PC. You commonly do this by double-clicking the application icon or its filename.

Step 3 Set up the PC as a TFTP server using the TFTP application setup or configuration facility.

The user interface of most TFTP applications includes 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 checkbox beside the word Server. To configure the local PC as a server, you click in this checkbox.

The TFTP server also allows selection of a "root" directory. You must select the directory in which the Cisco IOS and upgrade 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.

This is the recommended method. If you use this method, when you reload the router to cause the image to take effect in Step 20, you will remain connected to the router. (Using Telnet, you will lose connection to the router at that point in the process.)

• Establish a Telnet session from the PC to the router.

Step 5 Connect your PC's Ethernet, Fast Ethernet, or Token Ring port to the router's corresponding LAN port. Use the 10BaseT crossover cable provided if connecting to an
Ethernet or Fast Ethernet port. You must use Category 5 cable for Fast Ethernet routers.

---

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).

In the following steps, you will upgrade your CiscoPro router to a Cisco Enterprise router. If you have a model CPA100x, CPA160x, CPA25xx or CPA4500 router and plan to install an 11.2 image on the router, you must perform Step 6 through Step 14. These steps upgrade your router to allow Enterprise images to run on it. For additional information, refer to the Note on page 3.

Step 6 From the console, enter the following configuration command:

Step 7 From the console, enter the following configuration command and then Ctrl-Z to exit configuration mode:

Step 8 At the router prompt, enter the following command to copy the router upgrade utility from the CD-ROM drive of the PC to the router:

Step 13 Enter the reload command to reload the router:

Step 14 Redo Step 6 and Step 7.

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

Step 16 When prompted, enter the IP address of your local Microsoft Windows 3.1-based PC as in the following example:

Step 20 Enter the reload command to reload the router:

Installation Process for Bootstrap Software

This section provides steps that describe how to install the bootstrap software using a Microsoft Windows 3.1 PC and a TFTP server application. You can also set up your Macintosh or UNIX workstation as a TFTP server and follow the same steps.

To install the software using an rcp application, follow the same procedure and substitute rcp for TFTP in the instructions. You must also substitute the copy rcp bootflash command for the copy tftp bootflash command.

Step 1 Install any TFTP server application on the PC. (Not provided by Cisco.)

Step 2 Launch the TFTP server application on the PC. You commonly do this by double-clicking the application icon or its filename.

Step 3 Set up the PC as a TFTP server using the TFTP server application setup or configuration facility.

The user interface of most TFTP server applications includes 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 checkbox beside the word Server. To configure the local PC as a server, click in this checkbox.

The TFTP server also allows selection of a "root" directory. You must select the directory in which the Cisco IOS and upgrade 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.

You can do this in two ways:

• Connect the PC's COM port to the router's console port.

• Establish a Telnet session from the PC to the router.

Step 5 Connect your PC's Ethernet, Fast Ethernet, or Token Ring port to the router's corresponding LAN port. Use the 10BaseT crossover cable provided if connecting to an
Ethernet or Fast Ethernet port. You must use Category 5 cable for Fast Ethernet routers.

---

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).

Step 6 From the console, enter the copy tftp bootflash command.

Step 7 When prompted, enter the TFTP server's IP address.

Step 8 When prompted, enter the filename of the image to be copied to the router as in the following example:

Source file name? 80082002.bin

This example specifies the bootstrap image for Cisco 4500 and 4700 routers.

Step 9 In response to the prompt, enter the destination filename and press Enter to indicate that you want to copy the image.

This is the name you select for the image file on the router. You do not need to use the full pathname of the image on the CD-ROM attached to the PC. In this example, the UNIX filename is used:

Destination file name [80082002.bin]? c4500-boot-m.111-7

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

If the file is not found, check the following: filename; TFTP server is enabled; correct root directory is selected; IP connectivity between the router and TFTP server.

Step 10 Enter yes or no in response to the prompt asking if you want to erase the existing image copy resident in the router's Flash memory before copying the new one:

Erase flash device before writing? [confirm] yes

When copying to internal Flash memory, the system may provide an option to erase existing internal Flash memory before writing onto it. 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 periods (...), the transfer failed. Check IP connectivity between the router and TFTP server using the ping command.

Command Reference Pages for TFTP and rcp

This section includes reference pages providing detailed information about the copy rcp flash and copy tftp flash commands. This information supplements the information provided in the steps described earlier in the section "Installing the Router Software Without Using Windows 95,".

copy rcp flash

To copy a file from a network server to the router or to another destination using rcp, use the copy rcp flash EXEC command.

Syntax Description

Command Mode

EXEC

Usage Guidelines

The rcp protocol requires that a client send the remote username of an rcp request to the server. When you issue the copy rcp flash command, by default the Cisco IOS software sends the username associated with the current teletype (TTY), if that name is valid. For example, if the user is connected to the router through Telnet and the user was authenticated through the username command, then the software sends that username as the remote username.

If the TTY username is invalid, the software uses the host name as both the remote and local usernames. To specify a different remote username to be sent to the rcp server, use the ip rcmd remote-username command, and possibly the ip rcmd remote-host command. You can also specify the path of an existing directory along with the remote username.

If you copy a system image from a personal computer used as a file server, the remote host computer must support the remote shell (rsh) protocol.

Use the copy rcp flash to copy a system image from a network server to the router's internal Flash memory using rcp. The Cisco IOS software prompts for the address of the rcp server and rcp filename. When you issue this command, the system provides an option to erase existing Flash memory before writing onto it. The entire copying process takes several minutes and differs from network to network.

Before booting from Flash memory, verify that the checksum of the image in internal Flash memory matches the checksum listed in the README file distributed with the system software image. The checksum of the image in Flash memory is displayed at the bottom of the screen when you issue the copy rcp flash command. The README file was copied to the rcp server automatically when you installed the system software image.

 
Caution If the checksum value does not match the value in the README file, do not reboot the router. Reissue the copy rcp flash command and compare the checksums again. If the checksum is repeatedly wrong, copy the original system software image back into Flash memory before you reboot the router from Flash memory. If you have a corrupted image in Flash memory and try to boot from Flash memory, the router starts the system image contained in ROM (assuming booting from a network server is not configured). If ROM does not contain a fully functional system image, the router cannot function and must be reconfigured through a direct console port connection.

Examples

The following example shows how to use the copy rcp flash command on a Cisco 4500 router. The interface might differ slightly on other systems. This example copies a system image named file1 from the netadmin1 directory on the remote server named SERVER1.CISCO.COM with an IP address of 131.108.101.101 to Flash memory. To ensure that enough Flash memory is available to accommodate the system image to be copied, the Cisco IOS software allows you to erase the contents of Flash memory first.

Router1# configure terminal
Router1(config)# ip rcmd remote-username netadmin1
Router(config)# Ctrl-Z
Router# copy rcp flash

copy tftp flash

To copy a file from a TFTP server to the router or to another destination, use the copy tftp flash EXEC command.

Syntax Description

Command Mode

EXEC

Usage Guidelines

The system prompts for the address of the TFTP server and TFTP filename if you do not provide them at the command line. When copying to internal Flash memory, the system provides an option to erase existing internal Flash memory before writing onto it. The entire copying process takes several minutes and differs from network to network.

Before booting from Flash memory, verify that the checksum of the image in Flash memory matches the checksum listed in the README file distributed with the system software image. The checksum of the image in Flash memory is displayed at the bottom of the screen when you issue the copy tftp flash command. The README file was copied to the TFTP server automatically when you installed the system software image.

 
Caution If the checksum value is not correct according to the value in the README file, do not reboot the router. Issue the copy tftp flash command and compare the checksums again. If the checksum is repeatedly wrong, copy the original system software image back into Flash memory before you reboot the router from Flash memory. If you have a corrupted image in Flash memory and try to boot from Flash memory, the router starts the system image contained in ROM (assuming booting from a network server is not configured). If ROM does not contain a fully functional system image, the router cannot function and must be reconfigured through a direct console port connection.

The following example shows sample output of copying a system image named file1 into Flash memory:

Router# copy tftp flash
