These release notes describe the Cisco IOS Release 12.0(2a)T1 feature packs for Cisco 3600 series routers.
These release notes discuss the following topics:
This section explains how to use this document, describes feature pack components, and has tables that define the aspects of a feature pack.
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, "Feature Pack Product Numbers Quick-Reference List," to identify the software image you want to load.
2. Use Table 2, "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.
3. Use Table 4, "Feature Lists by Feature Sets for the Cisco 3600 Series, Part 1 of 2," and Table 5, "Feature Lists by Feature Sets for the Cisco 3600 Series, Part 2 of 2," to identify which features are supported in a feature set image.
4. Use Table 6, "Cisco 3600 Series Default Memory and Upgrade Options," to check the memory required for your feature set, determine the factory-default memory on the router, and view the available memory upgrades.
A feature pack is a small box that contains the following items:
The heart of a feature pack is the CD-ROM that contains software images and the Router Software Loader (RSL), which is a Windows 95 application that loads an image onto an access server or router. 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 the 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.
Table 1 lists the Cisco product numbers of the feature packs supported in this release.

Table 2 identifies each feature pack as specified on the router software CD-ROM label, describes the feature sets in each feature pack, and lists the UNIX and DOS filenames of the images, memory requirements, and the RSL installer description.
The Cisco IOS software is packaged into feature sets (also called images). Many different feature sets are available, and each feature set contains a specific subset of Cisco IOS features. The following conventions are used to identify feature sets:
Cisco IOS images with strong encryption (including, but not limited to, 56-bit DES) are subject to U.S. government export controls and have a limited distribution. Images to be installed outside the U.S. require an export license. Customer orders might 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.
The following list shows which feature sets are supported on the Cisco 3600 series routers. These feature sets only apply to Cisco IOS Release 12.0 T:
Table 4 and Table 5 list the features and feature sets supported by Cisco IOS Release 12.0(2a)T1 for the Cisco 3600 series. The feature set table uses the following terms:

Note These feature set tables contain only a selected list of features. This table is not a cumulative or complete list of all the features in each image.
This section describes the following:
Table 6 lists the default memory and the available memory upgrades.
The Cisco 3600 series includes the Cisco 3620 and Cisco 3640 routers. As modular solutions, the Cisco 3620 and 3640 enable corporations to increase dialup density and take advantage of current and emerging Cisco WAN technologies and networking capabilities. The Cisco 3600 series is fully supported by Cisco IOS software, which includes dialup connectivity, LAN-to-LAN routing, data and access security, WAN optimization, and multimedia features.
The following LAN interfaces are supported on Cisco 3600 series routers:
The following WAN data rates are supported on Cisco 3600 series routers:
The following WAN interfaces are supported on Cisco 3600 series routers:
The feature packs described in these release notes contain Cisco IOS Release 12.0(2a)T1 software images, some earlier images, and the Router Software Loader (RSL) Version 7.3. Before running the RSL, read the "Installing Software Images Using the RSL" section.
To view the version of Cisco IOS software that is running on your Cisco 3600 series router, log in to the router, and enter the show version user EXEC command:
The output begins similar to the following. The Cisco IOS version appears in the second line.
The output includes more information including processor revision numbers, memory amounts, hardware IDs, and partition information.
By default, the MICA modems installed on the Cisco 3600 series routers use the modem portware that is bundled with the Cisco IOS software image. Unless you are familiar with the Cisco MICA portware, we recommend that you use the default firmware and do not attempt to download another version.
If you do choose to override the firmware and portware selected by Cisco IOS software, the Flash memory of your router might contain modem code files that should be saved and restored before downloading the new image. Before the image download begins, the Router Software Loader (RSL) will display the Flash Copy Options dialog box, which will allow you to select which files to back up and restore. By default, RSL will back up all files in the selected Flash memory partition and restore the files you select.
If you want to verify that you are running the latest modem code, use the show modem version command to display the current version. Then compare that version to the modem code files available on the feature pack CD-ROM and on Cisco Connection Online (CCO).
If you are running Microsoft Windows 95 on a PC, we recommend using the RSL to download modem code. For detailed steps, refer to the RSL online help topic, "Downloading Modem Files." If you are running Windows NT, UNIX, or Macintosh, use TFTP or remote copy protocol (rcp) to download modem code. TFTP server instructions are in the online document titled Another Way to Download Modem Code.
Both RSL and TFTP instructions are available from the Software Center at the following URL:
http://www.cisco.com/public/sw-center/sw-access.shtml
Click on the link Router Software Loader (RSL). Follow the steps to download the new modem code.
This section provides solutions to problems you might encounter when using the RSL to load Cisco IOS software on a router. It also describes special cases that might require you to load Cisco IOS software on a CiscoPro router or to use an alternative to the RSL.
The Router Software Loader (RSL) Version 7.3 supports the following Cisco 3600 series routers:
This section describes some solutions to problems you might encounter when 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 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:
If you encounter this message, try increasing the Short Timeout value in the Options dialog box from 25 seconds, especially if one of the following situations applies:
Note Increasing the Short Timeout value might increase the time it takes for the RSL to connect to the target router.
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 has an upgrade utility to permanently modify a CiscoPro router so that it accepts Cisco IOS Release 12.0 software images. The utility changes the router SysObjectID Simple Network Management Protocol (SNMP) MIB value (used for network management) to that of a Cisco router. The software banner also changes and no longer identifies the router as a CiscoPro product.
Note After this upgrade, CiscoVision cannot recognize your router. If you choose the permanent upgrade, CiscoWorks for Windows is a recommended replacement for network management purposes. To upgrade your CiscoVision software to CiscoWorks Windows 2.1, order one of the following: CPW-CVCW-U to Upgrade CiscoVision to CiscoWorks Windows (managing up to 50 nodes) or CPW-CVCW-ENT-U to Upgrade CiscoVision to CiscoWorks Windows (managing up to 500 nodes). For general information about Cisco Systems, Cisco products, or upgrades, contact 800 553-6387, 408 526-7208, or cs-rep@cisco.com.
If you select a Cisco IOS Release 12.0 image from the image list and are connected to a CiscoPro CPA3600 series router, a message box tells you that the router requires a permanent upgrade to load this image. You can either select yes to have the RSL upgrade the router and continue loading the selected image or select no to cancel the load operation.
After you select yes, the RSL downloads, performs the upgrade, reboots the router, and issues a message to confirm the upgrade. Confirm this message. The RSL then downloads the selected image.
The upgrade utility must be located in the Images directory. If it is not, the upgrade utility informs you that the image is not present.
The Cisco 3600 series upgrade utility filename is cpa3600-upgrade-l.112-3.P. The upgrade utility is a special file, not a Cisco IOS run-time image. The RSL only installs valid software releases on Cisco 3600 series routers.
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:
This section explains how to use a TFTP server application 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 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 an rcp server. You can use the RSL or the TFTP server included on the feature pack CD-ROM to install the software only 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 as shareware from public sources on the World Wide Web.
Note To use an rcp application, follow this same procedure, but substitute rcp for TFTP in the instructions; for example, use 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 that includes a checkbox beside the word Server. To configure the local PC as a server, click this 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.
Step 4 Establish a console session from your local PC (which is now configured as a TFTP server) to the router by using one of these methods:
This is the recommended method. When you reload the router with the new image in Step 12, 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 router Ethernet port. Use an Ethernet crossover cable.
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).
Note We recommend that you back up the router configuration before upgrading the router software.
Step 6 Enter the following commands to enter enable mode and copy the new software image from the PC (set up as a TFTP server) to the router:
In the next series of steps, you download the Cisco IOS Release 12.0 images that you want installed on your router.
Step 7 When prompted, enter the IP address of your PC, as in the following example:
Address or name of remote host [255.255.255.255]? 172.16.1.1
This is the IP address of your local PC, not that of the router.
Step 8 When prompted, enter the filename of the Cisco IOS Release 12.0 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 a Cisco 3600 series router, as listed in Table 2.
Step 9 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 path name of the image on the CD-ROM attached to the PC. Refer to Table 2 in the "Cisco Feature Pack Image Filenames and Memory Requirements" section for the UNIX image filename.
Step 10 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.
During the transfer process, the software displays messages indicating that it has accessed the file you have specified and is loading it.
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 11 Enter the following commands to change the configuration register to 0x2102. This will force the router to reload to the image running from Flash memory.
Step 12 Enter the reload command to reload the router:
After reload is complete, the router should be running the desired Cisco IOS image. Use the show version command to verify.
