Configuring Interfaces
To configure a particular interface, you must create a network file/netdev file in /etc/systemd/network/
.
For example, to configure interface eth0 with DHCP, create network file 50-wired.network
and place it in /etc/systemd/network/:
[Match]
Name=eth0
[Network]
DHCP=ipv4
For more information on network file semantics, priority, and location, see the systemd-networkd man page.
