Introduction

This document explains the step-by-step procedure for upgrading the software image on Catalyst 5000/5500 series switches running CatOS on their supervisor module, and Cisco IOS® on the Route Switch Module (RSM) / Route Switch Feature Card (RSFC). The software image upgrade is required for the following reasons:

  • You want to implement new features in your network that are available in the new software release.

  • You want to install a new line card that is not supported by the current software version that you run on the switch.

  • Your switch has been affected by a known bug that is resolved in the next software release.

Before You Begin

Conventions

For more information on document conventions, see the Cisco Technical Tips Conventions.

Prerequisites

Before attempting this configuration, please ensure that you meet the following prerequisites:

  • verified memory and boot ROM requirements

  • downloaded the valid software image

  • installed the TFTP server on your PC

  • backed up the current switch configuration and software image

Verify Memory and Boot ROM Requirement

You should verify the minimum DRAM memory and boot ROM version required for the new software image, and whether your switch supports those requirements. The show version command displays the DRAM installed and the boot ROM version on your switch.

You can verify the requirements for the new software image using the respective release notes. Refer to the following release notes:

Download Software Image

The CatOS software image must be downloaded onto the PC that will act as the TFTP server prior to actual image upgrade. Download the software image from the Downloads. To download the software image, you must be a registered user and you must be logged in.

Install TFTP Server

For sample output for this document, we have installed a Cisco TFTP server on a PC running Microsoft ™ Windows 2000 Professional. You can use any TFTP server that can be installed on any platform. It is not necessary that you use a PC with a Windows OS.

160-a.gif

  1. Download and install any shareware TFTP software from the Internet on the PC that you will be using to copy the CatOS software image to the switch. The TFTP server root directory must be the directory to which the software image is downloaded. 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 is stored. For the Cisco TFTP server, you can change the root directory from the View Menu->Options.

    Note: The document was written when the Cisco TFTP server was available for download via the Downloads. Cisco no longer supports the Cisco TFTP server. If you are using the Cisco TFTP server, disable the logging function to prevent excessive logging, which can disrupt the TFTP process. Disable logging on the Cisco TFTP server from the View Menu->Options, deselect Enable Logging, and select Ok. By default, logging is enabled.

  2. Access the switch Command Line Interface(CLI) by connecting a console cable between the switch console port and the PC. Refer to Connecting a Terminal to the Console Port on Catalyst Switches to access the CLI using the hyperterminal.

    Note: The switch can be upgraded using remote Telnet access. However, you will loose Telnet connectivity when the switch is reloaded during the software upgrade. The Telnet can be re-established once it is loaded with the new image, but to troubleshoot in case of failure, it is essential to have local console access. A switch upgrade using console access is preferred

Backup Configuration and Software Image

Perform a backup of the switch configuration and the current software image to the PC running TFTP server. If your upgrade procedure fails due to reasons such as insufficient memory or not enough space on the bootflash of the switch to support the new image, you can always recover the switch to normal mode using the same image that was present in the switch. If you loose the switch configuration for any reason, you can always restore the configuration from the TFTP server. Refer to the following document for information on how to manage the configuration files and software images:

Components Used

This document is not restricted to specific software and hardware versions.

The information presented in this document was created from devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If you are working in a live network, ensure that you understand the potential impact of any command before using it.

Catalyst 5000/5500 Series Switches

The Catalyst 5000 switches have a variety of Supervisor modules available: Supervisor I, II, II G, III G, and III. The software upgrade procedure is different for Catalyst switches with Supervisor I, II, II G, III G, and Catalyst switches with Supervisor III.

CatOS Supervisor I, II, II G, III G

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

  1. By now, you should have verified the memory/boot ROM requirements, have the TFTP server on your PC, and the switch console accessed from the switch console port. If you are not ready with this setup, refer to Before You Begin section.

  2. Configure the management IP address (sc0) and check the connectivity between the switch and the PC on which the TFTP server is installed. It is recommended that you configure the PC and the switch management IP address in the same VLAN. If they are in different VLANs, make sure to configure the default gateway on the PC and the switch so that they can ping each other.

CatOS Supervisor III(WS-X5530)

The Catalyst 5000 Supervisor III supports two slots for the PCMCIA Flash card. If you have the PCMCIA Flash card installed on your switch, you have the choice to copy the new software image on bootflash or the PCMCIA Flash card. The bootflash is used in the procedure below. If you are using the PCMCIA Flash card, replace the bootflash: word in all of the commands below with slot0: or slot1:, depending on whether you have the image in slot 0 or slot 1.

  1. By now, you should have verified the memory/boot ROM requirements, have the TFTP server on your PC, and the switch console accessed from the switch console port. If you are not ready with this setup, refer to Before You Begin section.

  2. Configure the management IP address (sc0) and check the connectivity between the switch and the PC on which the TFTP server is installed. It is recommended that you configure the PC and the switch management IP address in the same VLAN. If they are in different VLANs, make sure to configure the default gateway on the PC and the switch so that they can ping each other.

  4. Copy the new software image into the bootflash from TFTP server and verify that the image is properly copied. Before you attempt to reload the switch with the new image, please check the filesize of the new image, and make sure that it matches the size mentioned on the Downloads on CCO. If there is a difference, it is possible that the image got corrupted during transfer. You may want to download it again in order to avoid the switch going into ROMmon mode after the reload.

    Note: PCs running Microsoft Windows OS may display the file size differently than the actual size. You should Right Click on the filename and select Properties to verify the actual file size in bytes.

Cisco IOS on RSM/RSFC Module

The following document explains the step-by-step procedure for upgrading the Cisco IOS on RSM:

The following document explains the procedure for upgrading the Cisco IOS on the RSFC:

Software Upgrade with Redundant Supervisors

You can not use the normal software upgrade procedure as mentioned above for Catalyst 5000/5500 switches that have redundant supervisor modules. Refer to the following document for upgrading the Catalyst 5000/5500 switches in redundant mode:

Verify

There is currently no verification procedure available for this configuration.

Troubleshooting Guidelines

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

Software Upgrade Failed / Switch is in ROMmon

Your software upgrade may fail due to reasons such as IP connectivity problems between the switch and TFTP server, incorrectly set boot variables, or the power may be off while copying the software image to the switch . These issues may cause your switch to boot in ROMmon. If your switch is in ROMmon and you do not have a valid image present on the bootflash or PCMCIA Flash card, you can recover your switch to normal mode using the software recovery procedure. Refer to the following documents for software recovery procedures:

Known Issue: Switch Configuration Lost Due to Software Downgrade

A software downgrade on a switch running CatOS will always cause the configuration to be lost. On Catalyst 5000s with Supervisor III, issue the copy config tftp command to back up your configuration to a TFTP server, or issue the copy config flash command to back up the configuration to a Flash device. If you have Catalyst 5000 switch with Supervisor I, II, IIG or IIIG, issue the write network command to back up the configuration to a TFTP server.

On Catalyst 5000s with Supervisor III, to restore the configuration after successful downgrade, issue the copy tftp config or copy flash config commands to get the configutation file from the TFTP server or Flash device. If you have Catalyst 5000 switch with Supervisor I, II, IIG or IIIG, issue the configure {host} {file} command to restore the configuration.

Refer to the Catalyst 5000 Command Reference Guide for the command syntax and more information in the use of these commands.
