In the previous section, we looked at how nmcli is used to configure static and dynamic IP addressing. Apart from the NetworkManager command-line interface and GUI interface, we can configure networking manually using network interface configuration files. At any one time, we can either configure networking using network interface files manually or using NetworkManager, but not both simultaneously. The location of the network interface files (scripts) varies from one Linux distribution to another. In the case of CentOS 7, the network interface configuration files are stored in the /etc/sysconfig/network-scripts/ folder and their naming conventions begin with ifcfg-<device_name>.
