Quick Steps to Upgrade Cisco Firmware Router

Rate this post

Cisco routers are deployed around the world in terms of network. And play pivotal roles in global wide area networks (WANs) as well as small networks. The security and stability built into a Cisco firmware upgrade router are the keys to the company’s market share, as these are two important traits that every network administrator wants in a network device. While the model and age of your specific equipment always determines the current firmware support level and Cisco has likely an upgrade for the particular firmware that runs the router.

Cisco Router IOS Upgrade

  • Step 1: Install the TFTP server on your computer. The full form of TFTP is Trivial File Transfer Protocol, which is used to transfer files from your computer to the router. There are several free TFTP servers such as Spiceworks, Solarwinds, and TFTPD32, that is available for download purpose on the Internet. Ping the router’s IP address to get surety if the TFTP server has IP connectivity to the router or not.
  • Step 2: In next step configure the TFTP software to run as a server, rather than as a client. During this you’re your computer will act as a server and the Cisco router will act as a client. Configure the directory for outbound files as per the instructions for the TFTP server you have previously downloaded.
  • Step 3: You need to select and download IOS image from the Cisco customer site to your TFTP server’s outbound directory. You must have a Cisco customer account in order to download and access new IOS images and the image you downloaded from it you need to must specify first that it is for your router model.
  • Step 4: In this step in need to connect your computer machine to the router via console port, using the blue console cable that will typically comes with the router. The cable has a DB-9 serial connector on one end while RJ-45 network jack on the other. Use HyperTerminal, Putty or any other available terminal emulator to connect to router and configure the terminal session settings as follows:

    9600 bits per second 8 data bits 0 parity bits 1 stop bit No flow control

  • Step 5: Connect the power cable to the router by booting up the router and a standard wall outlet. After the router runs via its startup diagnostics, you should always see the “router>” prompt. The actual prompt will quite a time vary if you already have renamed the router in a previous configuration session.
  • Step 6: In this step you need to type “enable” (without the quotes) at the prompt and press “Enter” after that. Type the enable password for the router and press “Enter” to enter into the enabled mode.
  • Step 7: Now copy the new IOS to flash memory. Type “copy tftp: flash” that too without the quotes at the prompt and then press “Enter.” Enter IP address of the TFTP server at the time of prompt and press “Enter.” At the time of “Source filename” prompt display, type the name of the IOS file that you have downloaded to the TFTP server and press “Enter.” Type “y” and press “Enter” to initiate the acceptance of the default destination filename. Type “y” and press the “Enter” key to erase all flash memory before copying the new IOS.
  • Step 8: Now check and verify the new version is now running the router by booting the router and typing “show version” at the prompt. If the Cisco Firmware Upgrade completed successfully, you should see your new IOS filename as the “System Image File” on the display.
