1.4. Network Configuration Using the Command Line Interface (CLI)

The commands for the ip utility, sometimes referred to as iproute2 after the upstream package name, are documented in the man ip(8) page. The package name in Fedora is iproute. If necessary, you can check that the ip utility is installed by checking its version number as follows:
~]$ ip -V
ip utility, iproute2-ss130716
The ip commands can be used to add and remove addresses and routes to interfaces in parallel with NetworkManager, which will preserve them and recognize them in nmcli, nmtui, control-center, and the D-Bus API.

Note

Note that ip commands given on the command line will not persist after a system restart.
Examples of using the command line and configuration files for each task are included after explaining the use of one of the graphical user interfaces to NetworkManager, namely, control-center and nm-connection-editor.
