These release notes include tables that identify feature packs and tables that show the specific features comprising available feature sets for each supported Cisco router. These release notes also help you navigate the electronic documentation for Cisco IOS Release 11.2. The Cisco Router Software Loader, delivered on the same CD-ROM as the Cisco IOS feature sets, is designed to work from a PC running Microsoft Windows 95. These release notes also describe how to install the router software feature sets using a PC running Microsoft Windows 3.1.

These release notes contain the following sections:

• Supported Platforms

• Loading Cisco IOS Release 11.2 Software on CiscoPro Routers

• Cisco Feature Pack Descriptions

• Memory Requirements and Recommendations

• Installation Tips

• Cisco IOS Release 11.2 Feature Sets

• Installing the Router Software Using Microsoft Windows 3.1

• Additional Release Note Information

• About Cisco IOS Software Electronic Documentation

• Cisco Connection Online

Supported Platforms

The Cisco Router Software Loader 4.0 supports the following Cisco 1000 series routers as follows:

• CiscoPro CPA1003, CPA1004, and CPA1005

• Cisco 1003, 1004, and 1005

Loading Cisco IOS Release 11.2 Software on CiscoPro Routers

The Router Software Loader 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 SNMP MIB (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.

If this happens, log into the router via the console port with Telnet or terminal emulation software. At the prompt ("rommon 1>" or ">"), enter the b flash command. The router will reboot to the new image in Flash memory.

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 tables in the section "Cisco IOS Release 11.2 Feature Sets,". Tables in that section identify which features are supported for a feature set on a specific platform.

Software Feature Packs

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 DOS and UNIX filenames of the images. The table provides a brief description of each feature set and the router platform on which the feature set runs.

Memory Requirements and Recommendations

This section includes two tables: Table 2 identifies the memory required to run each feature set on a Cisco 1000 series router platform; Table 3 describes the memory delivered by default for a particular router series and the memory upgrades available for that series.

You can use Table 2 to identify the memory required for your configuration based on the image you run. You can then check this against Table 3 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.

Table 3 shows the amount of both Flash and main memory delivered by default on a Cisco 1000 series router. It also lists the available memory upgrades.

Installation Tips

This section describes several solutions to problems you might encounter when using the Cisco Router Software Loader. These solutions are additions to the loader'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 in the Options dialog box, especially if one of the following situations applies:

• You are connecting to a router that requires the Token Ring interface to be configured. It sometimes takes the Token Ring interface longer to come up than the default Short Timeout value of 15 seconds. Try increasing the Short Timeout to 25 seconds.

• You are connecting to a router that has a large configuration file. Large configuration files may take longer than the default Short Timeout value of 15 seconds to be written to nonvolatile random-access memory.

• You are connecting to a Cisco AS5200. A Cisco AS5200 requires up to 45 seconds to write a configuration to nonvolatile random-access memory, due to the amount of interfaces that must be checked during this process. Increase the Short Timeout value to 50 seconds.

Preserving the Router's Startup Configuration

As part of the connection procedure, the Router Software Loader writes the current running configuration of the router to the startup configuration in NVRAM. This operation overwrites the previous startup configuration file.

Refer to the following steps to determine the operation mode of your particular router, and then how to reboot the router to run the image in Flash memory:

Step 1 After logging into the router, observe the command prompt.

Step 7 Enter the following configuration commands, one per line and end with Ctrl-Z:

Cisco IOS Release 11.2 Feature Sets

This section identifies specific features, within a category of features, supported on a particular router platform. Features marked with "Yes" are supported on the platform; features marked with "-" are not supported. Features marked with "Plus" are offered only in the Plus feature sets, not in the basic feature set. Features marked with "Encrypt," indicate the addition of 40-bit (Plus 40) or 56-bit (Plus 56) data encryption feature sets. You can use the information given in the tables provided in this section in conjunction with the information provided in the section "Cisco Feature Pack Descriptions,", to determine which features a particular feature set supports on a given platform.

Installing the Router Software Using Microsoft Windows 3.1

In addition to the router software, the CD-ROM also contains the Router Software Loader, which you can use to download the software to the router. The Router Software Loader is designed to work with a PC running Microsoft Windows 95. The booklet included with the CD-ROM explains how to perform this simple process.

This section describes an alternative method you can use to install the router software from the CD-ROM onto the router using a PC running Microsoft Windows 3.1. The process requires that you first obtain a Trivial File Transfer Protocol (TFTP) application or a remote copy protocol (rcp) application, which you can use to set up your PC 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 images to the router from a system running Microsoft Windows 3.1.

Installation Process

This section provides steps that describe how to install the router software using a Microsoft Windows 3.1 PC with a TFTP application.

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.

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 13, 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 Conect your PC's Ethernet port to the router's Ethernet port using the 10BaseT crossover cable provided.

---

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

---

In the following steps, you will upgrade your CiscoPro router to a Cisco Enterprise router. If you have a CiscoPro CPA1000, CPA1600, CPA2500 or CPA4500 router and plan to install an 11.2 image on the router, you must perform Step 6 through Step 13. These steps upgrade your router to allow Enterprise images to run on it. Refer to the Note on page 2 for details.

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

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:

The exclamation point (!) indicates that the copy process is taking place. Each exclamation point (!) indicates that ten packets have been transferred successfully. A series of "V" characters indicates that a checksum verification of the image is occurring after the image is written to Flash memory.

Step 13 Enter the reload command to reload the router:

Step 14 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 15 When prompted, enter the IP address of your local Microsoft Windows 3.1-based PC as in the following example:

The exclamation point (!) indicates that the copy process is taking place. Each exclamation point (!) indicates that ten packets have been transferred successfully. A series of "V" characters indicates that a checksum verification of the image is occurring after the image is written to Flash memory.

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 Using Microsoft Windows 3.1,".

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 the 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. 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. 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.

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. Enter 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.
