What is a Feature Pack?

The heart of a Cisco IOS software feature pack is a CD-ROM that contains software images and the Router Software Loader, a Windows 95 application, which loads the images onto the router. Each Cisco IOS Release 11.2 feature pack CD contains feature sets. For users without Windows 95, images can also be loaded with Windows 3.1 and a TFTP server application.

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


Note Before running the Router Software Loader, read the section "Installation Tips,".

Note If you are installing feature sets on a Cisco 3600 series router with no Ethernet or Token Ring interface, use the loading procedures described in the section "Installing the Router Software Using Microsoft Windows 3.1,".

Additional Information for Routers with ISDN BRI or ISDN PRI Interfaces

System configurations with multiple ISDN PRI interfaces or 12 or more ISDN BRI interfaces require more I/O memory than the default.

Cisco 3600 series routers ship with a 75/25 I/O memory split. If your router has 2 ISDN PRI interfaces or more than 12 ISDN BRI interfaces, you must change the memory split to 60/40. The following sections provide information about reallocating processor and I/O memory and provide examples of the memory-size iomem command. Note that if you do not reallocate memory, you will get an error code.

Reallocating Processor Memory and I/O Memory

DRAM memory in Cisco 3600 series routers is organized as one contiguous address space divided between processor memory and I/O memory. Depending on the type and number of network interfaces you have configured in the router, you may need to reallocate the DRAM memory partitioned to processor memory and I/O memory.

Cisco manufacturing configures most Cisco 3600 series routers to have 25 percent of the address space allocated to I/O memory and 75 percent allocated to processor memory. But for customers that use two or more ISDN PRI interfaces, DRAM memory must be configured to provide 40 percent of the address space for I/O memory and 60 percent for processor memory. See Figure 1.


Figure 1: Components and Uses of DRAM Memory for Cisco 3600 Series Routers



Note Routers running two or more ISDN PRI interfaces or 12 or more ISDN BRI interfaces require a DRAM memory configuration of 60 percent I/O memory and 40 percent processor memory.

There are cases where you may have to manually reallocate the DRAM memory split between processor memory and I/O memory after you have received a router from Cisco Systems.

For example, suppose your Cisco 3640 router has the following running configuration:

Later on however, you add a 4-port ISDN BRI network module to the router. You now have a total 12 ISDN BRI interfaces running on the router. At this point, you must use the memory-size iomem command to configure 40 percent of the address space for I/O memory and 60 percent for processor memory.

To view your current mix of processor and I/O memory and reassign memory distribution accordingly, enter the following commands beginning in privileged EXEC mode:

Task Command
Step 1 View the total amount of memory loaded on the router. show version
Step 2 Determine the amount of free memory. show memory1
Step 3 Enter global configuration mode. configure terminal
Step 4 Allocate processor memory and I/O memory. memory-size iomem I/O-memory-percentage2
Step 5 Exit global configuration mode. Ctrl-Z
Step 6 Write the new configuration to NVRAM. copy running-config startup-config
Step 7 Reload the router to run the new image. reload

1 The Free(b) column in the show memory command's output shows how much I/O memory is available.
2 The default is 40 percent for I/O memory and (60 percent for processor memory).

Valid I/O memory percentage values are 25, 30, 40 (the default), and 50. I/O memory size is the specified percentage of total memory size, rounded down to the nearest multiple of 1 MB. The remaining memory is processor memory.

The memory-size iomem command does not take effect until you save it to NVRAM using the copy running-config startup-config EXEC command and reload the router. However, when you enter the command, the software checks whether the new memory distribution leaves enough processor memory for the currently running Cisco IOS image. If not, the following message appears:

Warning: Attempting a memory partition that does not provide enough Processor memory for the current image.If you write memory now, this version of software may not be able to run.

When you enter the reload command to run a new image, the software calculates the new processor and I/O memory split. If there is not enough processor memory, it automatically reduces I/O memory to an alternative setting to load the image. If there is still not enough processor memory for the image to run, then you do not have enough DRAM.

See the next section for an example of how to configure the memory-size iomem command.

Reallocate Processor Memory and I/O Memory Examples

The percentage of DRAM allocated to I/O memory and processor memory is configurable.

The following example allocates 40 percent of DRAM to I/O memory and the remaining 60 percent to processor memory:

Step 1 From EXEC mode, enter the show memory command to see whether you need to allocate different percentages of processor and I/O memory. The Free(b) column shows how much I/O memory is available:

Step 2 Enter global configuration mode and configure the memory-size iomem command.

Step 3 Write the new configuration to NVRAM:

Step 4 Enter the reload command to run the new image and boot the router from ROM monitor mode:

memory-size iomem Command

To reallocate the percentage of DRAM memory to use for I/O memory and processor memory on Cisco 3600 series routers, use the memory-size iomem global configuration command. The no form of this command reverts to the default allocation of 25 percent I/O memory and 75 percent processor memory.

memory-size iomem I/O-memory-percentage
no memory-size iomem I/O-memory-percentage

Syntax Description
I/O-memory-percentage The percentage of DRAM allocated to I/O memory. The values permitted are 25, 30, 40, and 50 percent.
Default

The default allocation is 25 percent I/O memory and 75 percent processor memory.

Command Mode

Global configuration

Usage Guidelines

This command first appeared in Cisco IOS Release 11.2 P.

Once you specify the percentage of I/O memory in the command line, processor memory automatically takes on the remaining percentage of DRAM memory.

Example

The following configuration allocates 40 percent of the DRAM memory to I/O memory and the remaining 60 percent to processor memory.

Router# configure terminal
Router(config)# memory-size iomem 40
Router(config)# Ctrl-Z
Router# copy running-config startup-config
Building configuration...
[OK]

Installation Tips

This section describes several solutions to problems you might encounter when using the 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:


Note Increasing the Short Timeout value may increase the time it takes for the Router Software Loader to connect to the target router.

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.

 
Caution If your router is running in ROM monitor mode or from the bootstrap image in ROM, and if the current startup configuration was created while running a full Cisco IOS system image, you should copy the startup configuration file to a network server before running the Router Software Loader. Otherwise, you might lose several configuration commands that are not supported by the bootstrap image, such as all routing and bridging configurations.

As an option, if the router has a valid Cisco IOS image in Flash memory, you can reboot the router from the image in Flash memory before running the Router Software Loader. This way, your configuration commands will not be lost when the Router Software Loader writes the image to NVRAM. To do this, log into the router via the console port using Telnet or terminal emulation software. (If you use terminal emulation software, configure the software settings to 9600 baud, no parity, 8 data bits, and 1 stop bit.) Then follow Step 1 through Step 7 to reboot from Flash memory.

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.

If the prompt appears as a "rommon 1>" or ">," the router is operating in ROM monitor mode.


Step 2 To boot the router from the image in Flash memory, enter the following command:

The router will now load the Flash memory image. When the image is loaded, you can log out and start the Router Software Loader application.


If the prompt appears as "[router name](boot)>" or "[router name](boot)#," the router is running the bootstrap image.


Step 3 Enter the show version command at the prompt and examine the Configuration Register value shown in the last line of the show version output.

Step 4 If your router shows the "[router name](boot)>" prompt, enter the enable command and supply the password if necessary.

Step 5 If the last digit of the Configuration Register is greater than 1, enter the reload command to reboot the router to run the image in Flash memory.

Step 6 If the last digit of the Configuration Register is less than 2, you must change the Configuration Register value before reloading, as follows:

Step 7 Enter the following configuration commands:


The router will now reboot and load the image in Flash memory. (If you were logged in via Telnet, you will be logged out automatically when the reboot operation begins.)


After the router reboots, you can log out and start the Router Software Loader application.

Alternatives to the Router Software Loader

The Router Software Loader application contained on the feature set CD is designed to work with a PC running Microsoft Windows 95. The booklet included with the CD explains how to perform this simple process. However, two alternatives are available to download software in systems that do not use Windows 95:

Installing the Router Software Using the Console or Auxiliary Port

This type of installation uses the copy xmodem flash command.


Note The  transfer takes place only on the port at which you issue the comand. If you download via the console, all console output will be discarded for the duration of the transfer. You can only download files to the router; you cannot copy files from the router. Cisco recommends using the auxiliary port for this type of software download. The auxiliary port has hardware flow control and full modem control. In addition, the transfer will not occupy the system console.

The following example shows how to use the copy xmodem flash command on a Cisco 3600 series router.

Installing the Router Software Using Microsoft Windows 3.1

The Router Software Loader contained on the feature set CD is designed to work with a PC running Microsoft Windows 95. The booklet included with the CD explains how to perform this simple process. However, to download software using a system running Microsoft Windows 3.1 you need to follow the steps in this section.


Note You must use these procedures to load any software feature set onto a router that contains no Ethernet or Token Ring interfaces.

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 to the router from a PC running Microsoft Windows 3.1.


Note If you do not already have a TFTP or rcp application, you can choose from a number of TFTP server applications or rcp applications available from independent software vendors. In addition, a number of TFTP programs are available as shareware from public sources on the World Wide Web.

Installation Process

This section describes how to install the router software using a Microsoft Windows 3.1 PC with a TFTP server 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.

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.


 
Caution Be sure you set up your local PC as a TFTP server. If you overlook this step, you will not be able to perform the copy procedure. This reminder also applies if you are using rcp on your system instead of TFTP.

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:


This is the recommended method. If you use this method, when you reload the router with the new image in Step 11, you will remain connected to the router. (If you use Telnet, you will lose connection to the router.)

Step 5 Connect your PC's Ethernet port to the router's Ethernet port using the 10BaseT crossover cable provided.

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

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

Step 8 When prompted, enter the full pathname of the Cisco IOS Release 11.2 image to be copied to the router as in the following example:

Source file name? d:\cpswinst\images\80155204.bin


This example specifies the IP feature set for Cisco 3620 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, not the full pathname of the image on the CD-ROM attached to the PC. In this example, the UNIX filename is used:


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


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 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.


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 11 Enter the reload command to reload the router:

# reload


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.

copy rcp flash
Syntax Description
flash Specifies internal Flash memory as the destination of the copy operation.
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.


Note For Cisco, TTY lines are commonly used for access services. The concept of TTY originated with UNIX. For UNIX systems, each physical device is represented in the file system. Terminals are called TTY devices, which stands for teletype, the original UNIX terminal.

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.

 
Caution The remote username must be associated with an account on the destination server. If you do not use the ip rcmd remote-username command to specify the name of a remote user associated with an account on the server, then the remote username associated with the current TTY process must be associated with an account on the server. If there is no username for the current TTY process, then the host name must be associated with an account on the server. If the network administrator of the destination server did not establish accounts for the remote username used, this command will not execute successfully when a default remote username is used.

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 3600 series 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)# rcmd remote-username netadmin1
Router(config)# Ctrl-Z
Router# copy rcp flash

The following example shows sample output resulting from copying a system image into a partition of Flash memory. The system prompts only if there are two or more read/write partitions or one read-only and one read/write partition and dual Flash memory bank support in boot ROMs. If the partition entered is not valid, the process terminates. You have the option to enter a partition number, a question mark (?) for a directory display of all partitions, or a question mark and a number (?number) for a directory display of a particular partition. The default is the first read/write partition.

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

copy tftp flash
Syntax Description
flash Specifies internal Flash memory as the destination of the copy operation.

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.
