systemd-networkd.service(8)
NAME
systemd-networkd.service, systemd-networkd - Network manager
SYNOPSIS
systemd-networkd.service
/lib/systemd/systemd-networkd
DESCRIPTION
systemd-networkd is a system service that manages networks. It detects
and configures network devices as they appear, as well as creating
virtual network devices.
To configure low-level link settings independently of networks, see
systemd.link(5).
Network configurations applied before networkd is started are not
removed, and static configuration applied by networkd is not removed
when networkd exits. Dynamic configuration applied by networkd may also
optionally be left in place on shutdown. This ensures restarting
networkd does not cut the network connection, and, in particular, that
it is safe to transition between the initrd and the real root, and
back.
CONFIGURATION FILES
The configuration files are read from the files located in the system
network directory /lib/systemd/network, the volatile runtime network
directory /run/systemd/network and the local administration network
directory /etc/systemd/network.
Networks are configured in .network files, see systemd.network(5), and
virtual network devices are configured in .netdev files, see
systemd.netdev(5).
