Introduction

This document explains the step-by-step procedure to upgrade the software image on Catalyst 4500/4000 series switches that run CatOS on Supervisor I and II modules, Cisco IOS® on 4232-L3 module, and Cisco IOS on Supervisor III, IV, and V modules. The software image upgrade is necessary for these reasons:

Implement new features in your network which are available in new software releases.
Install a new line card that is not supported by the current software version you run on the switch.
Fix a known bug that affects your switch if the bug is resolved in the future software release.

Prerequisites

Background Information

This section describes the items in the Requirements section.

Verify Memory and Boot ROM Requirement

Verify the minimum amount of DRAM, Flash memory, and the boot ROM version necessary for the new software release. Check whether your switch supports these requirements. You can use the release notes to verify the requirements for the new software image. Refer to Release Notes for Catalyst 4500/4000 Series Switches.

The show version command displays the boot ROM version, DRAM installed, and the bootflash size on your switch.

Here is the output of the show version command on Catalyst 4500/4000 that runs CatOS:

Here is the output of the show version command on Catalyst 4500/4000 that runs integrated Cisco IOS:

Download Software Image

Download the software image on to the PC that acts as the TFTP server prior to the actual image upgrade. Download the CatOS or integrated Cisco IOS software image from the Catalyst 4000 Software Download Center (registered customers only) .

Install TFTP Server on Your PC

For sample output in this document, the Cisco TFTP server is installed on a PC with Microsoft Windows 2000 Professional. You can use any TFTP server that can be installed on any platform. You do not need to use a PC with a Windows OS.

Step 1: Download and install any shareware TFTP software from the Internet on the PC that you use to copy the software image to the switch. Download the software image to the TFTP server root directory. You can download the images to the default root directory of the TFTP server or change the root directory path to the directory in which the software image resides. For the Cisco TFTP server, select View Menu > Options to change the root directory.

Note: This document was written when the Cisco TFTP server was available for download through the Software Center. Cisco no longer supports the Cisco TFTP server. If you use the Cisco TFTP server, disable the log function to prevent excessive log generation, which can disrupt the TFTP process. Select View Menu > Options to disable logs on the Cisco TFTP server. Alternatively, deselect Enable Logging, and click Ok. By default, logging is enabled.

Step 2: Connect a console cable between the switch console port and the PC to access the switch Command Line Interface (CLI). Refer to Connecting a Terminal to the Console Port on Catalyst Switches for information on how to access the CLI through HyperTerminal.

Note: You can use remote Telnet access to upgrade the switch. However, you lose Telnet connectivity when the switch reloads during the software upgrade. You can re-establish the Telnet after the new image loads. However, to troubleshoot in case of failure, you need to have local console access. Cisco recommends a switch upgrade through the console access.

Backup Configuration and Software Image

Perform a backup of the switch configuration and the current software image to the PC that runs the TFTP server. Sometimes, your upgrade procedure can fail due to these reasons:

Insufficient memory
Insufficient space on the bootflash of the switch to support the new image

You can recover the switch to normal mode with the same image that was present in the switch. If you lose the switch configuration for any reason, you can restore the configuration from the TFTP server. Also, see the Known Issue: CatOS Switch Configuration Lost Due to Software Downgrade section of this document for more information. Refer to Managing Software Images and Working with Configuration Files on Catalyst Switches for information on how to manage the configuration files and software images on Catalyst 4000 switches that run CatOS.

On Catalyst 4500/4000 switches that run integrated Cisco IOS, you can issue the copy startup-config tftp: or copy startup-config bootflash: command to copy the configuration to the TFTP server or bootflash. If you have modified your configuration, make sure to issue the write memory command to copy the current configuration to startup configuration and perform the backup. You can issue the copy bootflash: tftp: or copy slot0: tftp: commands to copy the current software images from bootflash or slot0 to the TFTP server.

Configure

In this section, you are presented with the information to configure the features described in this document.

Note: Use the Command Lookup Tool (registered customers only) to obtain more information on the commands used in this section.

CatOS on Supervisor I and II Modules

The Catalyst 4003 (Supervisor I) and 4006 (Supervisor II) switches that run CatOS do not support the PCMCIA Flash card. You only have the option to copy the new software image from the TFTP server into the switch bootflash.

Step 1: Ensure that you verify the memory or bootROM requirements, and be ready with the TFTP server on your PC, and access the switch console from the switch console port. If you are not ready with this setup, see the Requirements section of this document.

Step 2: Configure the management IP address (sc0). Check the connectivity between the switch and the PC on which the TFTP server is installed. In this sample scenario, use the 10.10.10.1 IP address for switch management and the 10.10.10.2 IP address for the TFTP server.

Step 3: Verify whether you have enough space available in the bootflash to copy the new image from the TFTP server into the bootflash. You can check the size of the new image on the PC to which the image is downloaded.

In case there is not enough free space to copy the new image, delete the current image with the delete command. Issue the squeeze command to permanently erase files tagged as 'deleted' to make more space available for the new image.

Step 4: Copy the new software image into the bootflash from the TFTP Server and verify whether the image is properly copied. Confirm that the file size of the new image is an exact match with the size that the Software Center on Cisco.com (registered customers only) mentions. If you find a difference, the image probably became corrupt during transfer. Download the image again in order to ensure that the switch does not go into ROMmon mode after reload.

You can also confirm the checksum of the file on the Flash device with the verify command:

Step 5: Clear the old boot variable so that switch does not boot with an old image even if the image is available in bootflash. Configure the new boot variable so that the switch boots with the new software image after the reset.

Step 6: Reset the switch so that during reload the switch boots with the new software image.

Step 7: Verify whether the new software version is on the switch.

If the switch fails to load or remains in rommon> mode, see the Software Upgrade Failed / Switch is in ROMmon section of this document for further assistance.

Cisco IOS 4232-L3 Module

Refer to How to Upgrade Software Images on Catalyst Switch Layer 3 Modules for a step-by-step procedure to upgrade the software on 4232-L3 modules:

Cisco IOS on Supervisor III, IV, and V Modules

Refer to the Upgrading the System Software section of Release Notes for the Catalyst 4000 Family Switch Cisco IOS for a step-by-step procedure to upgrade the integrated Cisco IOS on Catalyst 4500/4000 Supervisor III and IV modules.

Upgrade the Software Images on Redundant Supervisor Modules Without a System Reload

The Cisco Catalyst 4500 series switches allow a standby supervisor engine to take over the function if the primary supervisor engine fails. This way, the Cisco Catalyst 4500 series switches allow the switch to resume operation quickly in the event of a supervisor engine failure. This capability is known as supervisor engine redundancy. The software upgrade procedure, which the supervisor engine redundancy feature supports, allows you to upgrade the Cisco IOS software image on the supervisor engines without a need to reload the system.

Complete these steps in order to upgrade the software:

Copy the new Cisco IOS software image to bootflash or slot0 on both supervisor engines with these commands:
- On the active supervisor:
  - copy source_device:source _filename slot0:target_filename
  - copy source_device:source_filename bootflash:target_filename
- On the standby supervisor:
  - copy source_device:source_filename slaveslot0:target_filename
  - copy source_device:source_filename slavebootflash:target_filename
Configure the supervisor engines to boot the new image. Use these commands:
Synchronize the supervisor engine configurations:
Issue the copy running-config start-config command to save the configuration.
Issue the redundancy reload peer command to reload the standby supervisor engine and bring the engine back online (with the new version of Cisco IOS software).
Note: Before you reload the standby supervisor engine, make sure you wait long enough so that all configuration synchronization changes are complete.
Conduct a manual switchover to the standby supervisor engine with the redundancy force-switchover command.
The standby supervisor engine becomes the active supervisor engine that runs the new Cisco IOS software image. The modules reload, and the module software downloads from the active supervisor engine. The originally active supervisor engine reboots with the new image and becomes the standby supervisor engine.

show version—Verifies whether the new switch runs the new software version.

Troubleshoot

This section provides information you can use to troubleshoot your configuration.

Software Upgrade Failed / Switch is in ROMmon

Your software upgrade can fail due to these reasons:

IP connectivity problems between the switch and TFTP server
Incorrectly set boot variables
Power failure during the copy operation of the software image to the switch

As a result, the switch can go into ROMmon mode. If your switch is in ROMmon and you do not have a valid image present on the bootflash or compact Flash (only on Supervisor III and IV), you can recover your switch to normal mode through the software recovery procedure. Refer to these documents for the software recovery procedure:

Redundant Supervisor Engine Software Upgrade Fails

If a software upgrade is performed on both the active and standby supervisor engines, check whether both the supervisors run the same new software image.

The upgrade fails when the primary supervisor downloads the configuration from the secondary supervisor. The secondary supervisor copies its own boot variable to the primary supervisor. If the primary supervisor does not have the same software image as the secondary supervisor, a boot loop occurs because the primary supervisor is unable to find the image. Complete these steps in order to resolve the problem:

Remove the primary supervisor.
Switch to the ROMMON mode.
Boot the promary supervisor manually.

Ensure that the primary supervisor loads the same image as in the other supervisor engine. After the image loads, reset your boot variables. After the supervisor engine recovers, upgrade one of the supervisors to have the same image as the other supervisor.

Known Issue: CatOS Switch Configuration Lost Due to Software Downgrade

A software downgrade on a switch that runs CatOS always leads to loss of configuration. Issue the copy config tftp command to back up your configuration to a TFTP server. Alternatively, issue the copy config flash command to back up the configuration to a Flash device.
