Release Notes for Cisco IOS Release 11.2(3) Software Feature Packs—Cisco 2500 Series Routers

Release Notes for Cisco IOS Release 11.2(3) Software Feature Packs—Cisco 2500 Series Routers

March 17, 1997

These release notes identify the Cisco Internetwork Operating System (Cisco IOS) Release 11.2 feature packs for Cisco 2500 series routers (Cisco and CiscoPro models). Product numbers for supported feature packs are as follows:

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 documentation. 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.

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

These release notes contain the following sections:

Note A feature pack can contain multiple feature sets, and each feature set contains many features.

Platforms Supported

The Cisco Router Software Loader supports the following Cisco 2500 series routers:

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.

Caution If, when using the Router Software Loader, you select Preconfigured router and you uncheck the Configure Ethernet interface 0 box (or Token Ring 0), the upgrade utility will load selected Cisco image successfully to the router's Flash memory, but the router will reboot in ROM monitor mode.

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.

Caution Remember that you must manually change the Configuration Register of the router back to the original setting it had before the loading process. After the router reboots, enter enable mode by typing enable <Return>, followed by the password if set. Enter configuration mode by typing config t <Return>, then enter the commands: config-register 0x2102 <Return> and exit <Return>.
Note After this upgrade, your router will no longer be recognized by CiscoVision. If you perform the permanent upgrade and currently use the CiscoVision network management application, CiscoWorks for Windows is a recommended replacement for network management purposes. You can upgrade your CiscoVision software to CiscoWorks Windows 2.1 by ordering 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).

The upgrade utility must be in the same directory as the selected image. If it is not, the upgrade utility will inform you that the image is not present. If you use an image directory other than the one on the CD, make sure you copy the proper upgrade utility to that directory. The Cisco 2500 series upgrade utility is cpa25-upgrade-l.112-3.P.

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.

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.

Enabling the Hub Port

This installation tip applies to the Cisco 2505, 2507, 2516, CPA2505, CPA2607, and CPA2516. When connecting to one of these routers via the Router Software Loader, you must first enable the hub port used to connect the router to your PC. To enable the hub port, you will need to log into the router via the console port. You can log into 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.)

An example of enabling the hub port follows:

Step 1   When the router boots up, enter the enable mode as follows:

router> enable password: <password> router#

Step 2   Enter the configuration mode and enable the hub port, as follows:

router# configure terminal

Step 3   Enter the following configuration commands, one per line and end with Ctrl-Z.

router(config)# hub ether 0 port number of PC connection router(config-hub)# no shutdown

Step 4   Exit the configuration mode by entering the commands as follows:

router(config-hub)# exit router(config)# exit router#

Step 5   Log out of the router and start the Router Software Loader application.

RFF Platforms (Cisco 1600 Series, 2500 Series, CPA1600 Series, CPA2500 Series) with Partitioned Flash Memory

The following installation tip applies to any Cisco 1600 series or Cisco 2500 series router that has two or more Flash memory partitions. If you are unsure whether your router has multiple Flash memory partitions, issue the show flash command at the router prompt as shown in Step 4 of this section.

The Router Software Loader always copies to the default Flash memory partition of the router. In most cases, the default partition is partition 1. However, if your run-from-flash (RFF) router is running a Flash image located in partition 1, the default partition is partition 2. In this case, the Router Software Loader will copy the new image to partition 2, and reload the router with the image that still resides in partition 1.

We recommend that you unpartition your Flash memory before using the Router Software Loader to upgrade your router's Cisco IOS image.

Note If you are using a Cisco CPA1600 series or CPA2500 series router, you must unpartition your Flash memory before using the Router Software Loader to upgrade your router's Cisco IOS image. Otherwise, the router upgrade necessary to load the 11.2 images will transparently fail. In other words, the loader will indicate that the upgrade was completed when it actually was not.

To unpartition your Flash memory, take the following steps:

Step 1   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.)

Step 2   When the router boots up, enter the enable mode, as follows:

router> enable password: <password> router#

Step 3   Erase the contents of the Flash memory partition except the one currently in use (this partition will be in the Read ONLY state in the partition listing), as shown below.

router# erase flash Partition Size Used Free Bank-Size State Copy Mode 1 8192K 3724K 4467K 8192K Read ONLY RXBOOT-manual 2 8192K 3724K 4467K 8192K Read/Write Direct System flash directory, partition 2: File Length Name/status 1 3813972 cpa25-y-l.111-6.1 [3814036 bytes used, 4574572 available, 8388608 total] Erase flash device, partition 2? [confirm] Are you sure? [yes/no]: y Erasing device... eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee ...erased router#

Step 4   Enter the show flash command to verify that the desired Flash memory partitions have been erased:

router# show flash System flash directory, partition 1: File Length Name/status 1 3813972 cpa25-y-l.111-6.1 [3814036 bytes used, 4574572 available, 8388608 total] 8192K bytes of processor board System flash (Read ONLY) System flash directory, partition 2: No files in System flash [0 bytes used, 8388608 available, 8388608 total] 8192K bytes of processor board System flash (Read/Write)

You are now ready to unpartition the Flash memory.

Step 5   Enter the configuration mode and enter the partition command to create a single Flash memory partition, as follows:

router# configure terminal Enter configuration commands, one per line. End with cntrl/z. router(config)# partition flash 1

Step 6   Exit the configuration mode and verify that flash memory now has a single partition, as follows:

router(config)# exit router# show flash System flash directory: File Length Name/status 1 3813972 cpa25-y-l.111-6.1 [3814036 bytes used, 12963180 available, 16777216 total] 16384K bytes of processor board System flash (Read ONLY) router#

You can now log out of the router and start the the Router Software Loader application.

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 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:

> b flash

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:

router# configure terminal

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

router(config)# config-register 0x2102 router(config)# exit router# reload

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.

In addition to the Cisco IOS feature sets, the CD-ROM also contains the Router Software Loader, which you can use to download the software to the router. The booklet included with the CD-ROM explains how to install the software on a PC running Windows 95, but you can also install the software using Windows 3.1.

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 how to install the software images from the CD-ROM using a PC running 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 software images to the router from a system running Windows 3.1.

Note If you do not already have a TFTP or rcp application, you can choose from a number of applications that are 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 provides steps that enable you to install the router software using a TFTP application and a PC running Windows 3.1.

Note This is a two-part process. In the first part, which begins at Step 6, you will download the upgrade utility. In the second part, which begins at Step 15, you will download the Cisco IOS 11.2 images (referenced by the DOS names in Table 1) that you want on your particular router.

To install the software using an rcp application, follow the same steps but use rcp instead of TFTP. You must also substitute the copy rcp flash command for the copy tftp flash command in Step 8. See the next section, "Command Reference Information for TFTP and rcp," for detailed information about the copy rcp flash and copy tftp flash commands.

Step 1   Install any TFTP application on the PC. (Not provided by Cisco.)

Step 2   Launch the TFTP application on the PC, usually 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, 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 copy the new software images. If you are using rcp instead of TFTP, you should also be certain to set up your local PC as an rcp server before you copy the software images.

Step 4   Establish a console session from your local PC (which is now configured as a TFTP server) to the router. You can do this in two ways:

  This is the recommended method. If you use this method, you will remain connected to the router when you reload the router to cause the image to take effect (in Step 13).

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

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 3 for details.

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

# config terminal

Step 7   From the console, enter the following configuration command:

# config-reg 0x2102

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:

(In the next series of steps, you download the Cisco IOS 11.2 images that you want installed on your upgraded router.)

# copy tftp flash

Step 9   When prompted, enter the IP address of your local 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 10   When prompted, enter the full pathname of the image to be copied to the router as in the following example:

Source file name? d:\cpswinst\images\cpa25-upgrade-l.112-3.P

Step 11   In response to the following prompt, enter the destination filename and press Enter to indicate that you want to copy the image:

Destination file name [d:\cpswinst\images\cpa25-upgrade-1.112-3.p]? cpa25-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 CD-ROM on the PC.)

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

Step 12   Enter yes or no in response to the prompt asking if you want to erase the existing image in the router's Flash memory before copying the new one:

Erase flash device before writing? [confirm] yes

When copying to 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 13   Enter the reload command to reload the router:

# reload

At this point your CiscoPro router has been upgraded to a Cisco Enterprise router. Because the original Cisco IOS image, which resided in Flash memory, was erased during the upgrade process, the router should now be running in bootstrap (boot)# mode.

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:

(boot)# copy tftp flash

In the next series of steps, you download the Cisco IOS 11.2 images that you want installed on your upgraded router.

Step 15   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 that of the router.

Step 16   When prompted, enter the full pathname of the Cisco IOS 11.2 image to be copied to the router as in the following example:

Source file name? d:\cpswinst\images\80135403.bin

This example specifies the IP feature set for Cisco 2500 series routers.

Step 17   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 of the image file on the router, not the full pathname of the image on the CD-ROM attached to the PC.

Destination file name [d:\cpswinst\images\]?c2500-i-l

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

Step 18   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 19   Enter the reload command to reload the router:

(boot)# reload

Command Reference Information for TFTP and rcp

This section includes detailed information about the copy rcp flash and copy tftp flash commands. This information supplements the information provided in the steps described 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:

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 enter 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 TTY lines are commonly used for access services for Cisco routers. 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 PC 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 enter 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. Re-enter 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.

Router1# configure terminal Router1(config)# rcmd remote-username netadmin1 Router(config)# Ctrl-Z Router# copy rcp flash

OK (0x14B3) Flash copy took 0:00:01 [hh:mm:ss]

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.

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 enter 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.
