These release notes describe the Cisco IOS Release 12.0(4)T feature packs for Cisco 3600 series routers and contain the following topics:
This section explains how to use this document and describes feature pack components.
The tables in these release notes contain details about the Cisco feature packs. Use these tables to perform the following tasks before loading a software image onto a router:
1. Use Table 1, "Cisco 3600 Series Routers Default Memory and Upgrade Options," for the feature set memory requirements, and the factory-default memory and available memory upgrades for your router.
2. Use Table 2, "Feature Pack Product Numbers," to identify the software image you want to load.
3. Use Table 3, "Cisco Feature Pack Image Filenames and Memory Requirements," to identify your feature pack and the memory required for your feature set, based on the image you load.
4. Use the tables in the "Feature Set Tables" section to identify which features are supported in a feature set image.
A feature pack is a box that contains the following items:
The heart of a feature pack is the CD-ROM that contains software images and the RSL, which is a Windows 95 application that loads an image onto an access router or server. Each feature pack CD-ROM contains at least one Cisco IOS feature set. The CD booklet, Getting Started with the Router Software Loader, explains how to use the RSL to install the router image. If you cannot use the RSL to load images, you can follow the instructions in the "Alternatives to the RSL" section.
Before running the RSL, read the "Installing Software Images Using RSL" section. If you are loading software on a preconfigured router, you should save the router configuration file on your PC before beginning the image download process, as described in Getting Started with the Router Software Loader.
This section describes the following topics:
Table 1 describes the memory requirements and upgrade options for the Cisco 3600 series for Release 12.0(4)T.
The Cisco 3600 series includes the Cisco 3620 and Cisco 3640 routers. As modular solutions, the Cisco 3620 and 3640 routers enable corporations to increase dial-up density and take advantage of current and emerging Cisco wide-area network (WAN) technologies and networking capabilities. The Cisco 3600 series is fully supported by Cisco IOS software, which includes dial-up connectivity, LAN-to-LAN routing, data and access security, WAN optimization, and multimedia features. Multiservice applications are supported by integrated voice network modules.
The following LAN interfaces are supported on Cisco 3600 series routers:

This section describes the following topics:
This section describes some solutions to problems you might encounter when installing software images using the RSL. These solutions are additions to the RSL online help.
This installation tip provides a possible recovery solution if 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 access server:
If you encounter this message, especially if one of the following situations applies, try increasing the Short Timeout value higher than 25 seconds in the Options dialog box:
Note Increasing the Short Timeout value might increase the time it takes for RSL to connect to the target access server.
In some cases, the RSL is unable to restore the startup configuration. If this happens, take the following steps:
Step 2 Restart the RSL, and connect by 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 the router is 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 nonvolatile memory.
The router should now contain the startup configuration it had before the initial RSL connection. You can now exit the RSL.
Note In the previous situation, the router configuration register (config-register 0xnnnn) is not restored.
Note If you press Ctrl-Alt-Delete to terminate the RSL, the router configuration and configuration register are not restored. However, in this case, the configuration file is not deleted from the PC, so you can restore it using the previous steps, beginning with Step 2.
The following information about RSL operations can help you with the installation process:
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:
This section explains how to use the copy xmodem flash command to install the router software from the CD-ROM onto the router.
Note The transfer takes place only on the port at which you enter the command. If you download via the console, all console output is 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 does not occupy the system console so it is free for other uses.
The following example shows how to use the copy xmodem flash command on a Cisco 3600 series router.
Use this TFTP server application method 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 router 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 a rcp server. Only use the RSL or the TFTP server included on the feature pack CD-ROM to install the router software 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 available as shareware from public sources on the World Wide Web.
Note To use an rcp application, follow the same procedure below, substituting "rcp" for "TFTP"and using the copy rcp flash command instead of the copy tftp flash command.
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, and configure the local PC as a server by selecting the Server checkbox.
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 applies to both TFTP and rcp. |
Step 4 Establish a console session from your local PC (which is now configured as a TFTP server) to the Cisco router by using one of these methods:
This is the recommended method.When you reload the router with the new image in Step 25, you remain connected to the router. (If you use Telnet, you lose connection to the router.)
Step 5 Connect your PC Ethernet port to the corresponding router LAN port. Use the 10BaseT crossover cable to connect to an Ethernet port. Use straight-through cables if you are connecting via a 10BaseT hub or a 100BaseT hub.
Note We recommend that you back up the router configuration before upgrading the router software.
Step 6 Enter the following commands to set the configuration register to 0x2101 and reload to the bootstrap image:
Step 7 When asked whether the system configuration has been modified, enter yes:
Step 8 If the password prompt appears, enter the password.
Step 9 At the router prompt, enter enable and then the password:
Step 10 If you are not upgrading a CiscoPro CPA1600 router, skip to Step 19.
Step 11 At the router prompt, enter the following command to copy the router upgrade utility from the PC CD-ROM drive to the router:
Note If you are using rcp, enter copy rcp flash instead.
Step 12 When prompted, enter the IP address of your 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. (Note that you can obtain your PC IP address from the DOS prompt in the windows directory by entering winipcfg, as follows: C:\WINDOWS> winipcfg.)
Step 13 When prompted, enter the filename of the image to be copied to the router as in the following example:
Source file name? cpa1600-upgrade-l.112-3.P
Note The upgrade image file on the Feature Pack CD has a long filename (cpa1600-upgrade-l.112-3.P); note that DOS displays it in 8.3 format as cpa1600~1.P. The upgrade utility is a special file, not a Cisco IOS run-time image.
Step 14 In response to the following prompt, enter the destination filename, and press Enter.
Destination file name [cpa1600-upgrade-l.112-3.P]? cpa1600-upgrade-l.112-3.P
(This is the name of the image file on the router, not the full pathname of the image on the PC CD-ROM.)
During the transfer process, messages indicate that the software has accessed the file you have specified and is loading it.
If the file is not found, check the following:
If the file is still not found, create a temporary directory entitled "C:\temp," and copy the CiscoPro upgrade file into the directory. Select the C:\temp directory as the root directory.
Step 15 When asked whether you want to erase the existing image in the router Flash memory before copying the new one, enter yes:
Erase flash device before writing? [confirm] yes
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 or more periods (...), the transfer might fail. If the transfer fails, use the ping command to check IP connectivity between the router and TFTP server.
Step 16 Enter the reload command to reload the router:
Do not save the configuration.
After reload is complete, your CiscoPro router has been upgraded to a Cisco Enterprise router. Because the original Cisco IOS image that resided in Flash memory was erased during the upgrade process, the router is now running in bootstrap mode.
Step 17 If the password prompt appears, enter the password.
Step 18 At the router prompt, enter enable and then the password:
Step 19 At the router prompt, enter the following command to copy the new software image from the PC CD-ROM drive to the router:
Router(boot)(config)# copy tftp flash
In the next series of steps, you download the Cisco IOS Release 12.0 T images that you want installed on your router.
Step 20 When prompted, enter the IP address of your 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 that of the router.
Step 21 When prompted, enter the filename of the Cisco IOS Release 12.0 T image to be copied to the router, as in the following example:
This example specifies the DOS image name of the IP feature set for Cisco 3600 series routers (as shown in Table 3 in the section, "Feature Pack Overview Table").
Step 22 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 pathname of the image on the CD-ROM attached to the PC. Refer to Table 3 in the section, "Feature Pack Overview Table" for the UNIX image filename.
During the transfer process, the software displays messages indicating that it has accessed the file you have specified and is loading it.
Step 23 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.
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 24 Enter the following commands to reset the configuration register to 0x2102.
Step 25 Enter the reload command to reload the router:
After reload is complete, the router should be running the required Cisco IOS image. Use the show version command to verify.
