Feature Pack Descriptions

This section describes the feature packs, and lists the software feature sets in each pack. You can use this information to identify your feature pack together with the information in Table 4, "Cisco IOS Release 11.1(7)AA Feature Sets for Cisco CPA3620 and CPA3640 Routers" on page 4.

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 Upgrades

Table 2 shows the amounts of both Flash and DRAM required by Cisco 3600 feature sets. Table 3 lists factory default memory and the upgrade options that are available.

Special Note for Routers with ISDN BRI or ISDN PRI Interfaces

Cisco 3600 series router memory is organized as one contiguous address space, which is divided into processor memory and I/O memory. System configurations with multiple ISDN PRI interfaces or 12 or more ISDN BRI interfaces require more I/O memory than the default.

Cisco 3600 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. Use the memory-size iomem command to reallocate memory, as follows:

For more information about the memory-size iomem command, see the Configuration Notes for Cisco IOS Release 11.1 publication (part number 78-3939-xx) that shipped with your feature pack.

Cisco IOS Release 11.1 (7)AA Feature Sets for Cisco 3600 Series Routers

Table 4 lists specific features in categories of features that are supported on Cisco 3600 series routers. "Yes" indicates that this feature is supported; "-" indicates that this feature is not supported. You can use the information in this table together with the information provided in the section "Feature Pack Descriptions"on page 2 to determine which features a particular feature set supports on your router.

Installing the Router Software Using Microsoft Windows 3.1

In addition to the Cisco IOS feature sets, the CD-ROM also contains the router image loader, which you can use to download the software to the router. The router image 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. However, you cannot use the router image loader on a system running Microsoft Windows 3.1.

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 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 6.

Step 1   Install the TFTP application on the PC.

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.

Caution Be certain to 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 either of two ways:

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

  This is the recommended method. If you use this method, when you reload the router to cause the image to take effect in Step 11, 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 port to the router's Ethernet port using the 10BaseT crossover cable provided.

---

Note Use straight-through cables if you are connecting by means of a 10BaseT hub.

---

Step 6   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:

# copy tftp flash

---

Note If you are using rcp, enter copy rcp flash instead.

---

Step 7   When prompted, enter the IP address of your local Microsoft Windows 3.1-based 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.

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

Source file name? d:\images\cisco.mz

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

Destination file name [d:\images\cisco.mz]?cisco.mz

(This is the location and name of the image file on the router, not the full path name of the image on the CD-ROM attached to the PC.)

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 rcp and TFTP

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 "Installation Process,".

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.

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 command 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.

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.

If the partition is read-only and has dual Flash memory bank support in boot ROMs, the session continues as follows:

The file will be copied into the partition given earlier by the user:

If the partition is read/write, the session continues as follows:

The file will be copied into the partition given earlier by the user:

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.

Examples

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

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.

The following example shows sample output resulting from copying a system image into a partition of Flash memory. The system will prompt 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 can enter a partition number, a question mark (?) for a directory display of all partitions, or a question mark and a number (?number) for directory display of a particular partition. The default is the first read/write partition.

If the partition is read-only and has dual Flash memory bank support in boot ROMs, the session continues as follows:

The file will be copied into the partition given earlier by the user:

If the partition is read/write, the session continues as follows:

The file will be copied into the partition given earlier by the user:
