People across the world use Cisco routers that play critical roles from small networks to wide area networks (WANs) globally. The security and stability assembled into a Cisco router are essential to the market share of the company, as these are two qualities that every network admin needs in the network device. When the model and age of the particular equipment checks the existing firmware backing level, the Cisco possibly has an update for the firmware that operates the router. Before communicating with the Cisco experts via Cisco customer support number, you should follow these instructions to update the firmware.
- First of all, install a TFTP (Trivial File Transfer Protocol) server on the PC, which is used to send the file from your system to the router. There’re numerous free TFTP servers, including Spiceworks, TFTPD32, and Solarwinds, available for downloading from the web. Ping the IP address of your router to make sure the TFTP server has connected to the router.
- Set the TFTP program to work as a server, instead of as a client. Your PC will perform as a server, and the Cisco router will work as a customer. Set the manual for external files as per the guidance for the TFTP server you have downloaded.
- Choose an IOS image from the official site of Cisco and download it to the external directory from the TFTP server. You should have a Cisco customer account to open and download recent IOS images, and the downloaded image must specify that it’s for the router model.
- Connect your PC to the router through the console port, with a blue console cable that usually comes with your router. Use PuTTy, HyperTerminal, or any other computer emulator to make the connection with your router. Set up the final session configuration as well.
- Boot your router by connecting the electrical cable to the router and an ordinary power outlet. After running the router via its startup diagnostics tool, you should find the ‘router>’ prompt. If you have changed the router in an earlier configuration process, the actual prompt will differ.
- Input ‘enable’ at the reminder and press ‘Enter’ key. Provide the enable password of your router and press the ‘Enter’ to get into the enabled mode. Make a copy of the new IOS to flash memory. Input the ‘copy TFTP: flash’ at the reminder and press the ‘Enter’ key.
- Type the TFTP server’s IP address at the prompt and press the ‘Enter.’ At the ‘Source filename’ reminder, input the IOS filename that you downloaded to the TFTP server and click the ‘Enter’ button. Input ‘y’ and click the ‘Enter’ button to agree to the filename of default destination. Remove flash memory before you copy the new IOS by typing the ‘y’ and press the enter key.
- Check that the new version is operating the router by booting it and opening ‘show version’ at the reminder. If the update finished successfully, you must check the new IOS filename as the ‘System Image File’ icon on the screen.
Keep in mind that without the Cisco customer account and TFTP server software, you might not be able to update the firmware for your router. Before you upload the new file, you should first backup the router configuration files. However, if the firmware doesn’t work after updating, or you have any technical issues with your Cisco router, instantly call on the Cisco router tech support phone number and seek the help and result-oriented resolutions.
