This configuration will then be used on next startup. To back up we can save the configuration to a remote TFTP server with use of the "copy run tftp" command. Always have a back up plan.
To configure a TFTP server on Fedora, first install the TFTP server package using the command sudo dnf install tftp-server. Next, edit the TFTP configuration file located at /etc/xinetd.d/tftp to enable the service by setting disable = no. Afterward, ensure the TFTP root directory (typically /var/lib/tftpboot) exists and has the appropriate permissions, then start and enable the xinetd service with sudo systemctl start xinetd and sudo systemctl enable xinetd. Finally, test the TFTP server using a TFTP client.
