How to Upgrade Cisco IOS on a 3550 Switch




Cisco IOS is the operating system that runs on Cisco devices, such as routers and switches. It provides the functionality and features that enable network connectivity, security, and management. Upgrading Cisco IOS can improve the performance, stability, and security of your network devices.


In this article, we will show you how to upgrade Cisco IOS on a 3550 switch using the c3550-ipservicesk9-mz.122-55.SE8.tar file. This file contains the IOS image and the web-based device manager (Cisco Network Assistant) for the 3550 switch. The file name indicates that it supports IP services features and cryptographic functions (k9), and that it is based on IOS version 12.2(55)SE8.

Prerequisites




Before you begin, make sure you have the following:


  • A 3550 switch with enough flash memory (at least 16 MB) and DRAM (at least 128 MB) to support the new IOS image.



  • A TFTP server that is reachable from the switch and has enough disk space to store the IOS image file.



  • A console cable and a terminal emulator software (such as PuTTY) to access the switch console.



  • A backup of your current switch configuration and IOS image in case you need to revert to them.



Steps




Follow these steps to upgrade Cisco IOS on a 3550 switch:


  • Download the c3550-ipservicesk9-mz.122-55.SE8.tar file from Cisco's website or from a mirror site. Save it to your TFTP server directory.



  • Connect to the switch console using the console cable and the terminal emulator software. Log in with your credentials and enter privileged mode.



  • Verify your current IOS version and flash memory usage by issuing the show version and show flash: commands. Note down the current IOS image name and size, and the available flash memory.



  • Copy the new IOS image file from the TFTP server to the switch flash memory by issuing the archive download-sw /overwrite /reload tftp:///c3550-ipservicesk9-mz.122-55.SE8.tar command. Replace with the actual IP address of your TFTP server. The /overwrite option will erase the existing IOS image file from the flash memory, and the /reload option will reboot the switch after the download is complete. You can omit these options if you want to keep the old IOS image file or reboot manually later.



  • Wait for the download process to finish. You will see messages indicating the progress and status of the download. If there are any errors, check your network connectivity, TFTP server settings, and flash memory space.



  • After the switch reboots, verify that the new IOS image is loaded by issuing the show version command again. You should see the new IOS image name and version in the output.



If you want to use the web-based device manager (Cisco Network Assistant), you need to extract it from the tar file by issuing the archive tar /xtract flash:c3550-ipservicesk9-mz.122-55.SE8.tar flash: command. This will create a directory named c3550-ipservicesk9-mz.122-55.SE8 in your flash memory, which contains the HTML files for the device manager. You can access it by opening a web browser and entering


Troubleshooting




If you encounter any problems during or after the upgrade process, here are some tips to troubleshoot them:


  • If you cannot boot from the new IOS image, you can try to boot from the old IOS image by changing the boot variable in ROMMON mode. To enter ROMMON mode, power off the switch, press and hold the Mode button, and power on the switch. Release the Mode button when you see a prompt that starts with rommon>. Then issue the set BOOT flash: command, where is the name of your previous IOS image file. Then issue the boot command to boot from the old IOS image.



  • If you want to delete the new IOS image file or the device manager directory from the flash memory, you can use the delete /force /recursive flash: command.



  • If you need more help, you can refer to the Cisco documentation or the Cisco Community forum for more information and guidance.
