       systemd-networkd.service, systemd-networkd - Network manager

SYNOPSIS         top

       systemd-networkd.service

       /usr/lib/systemd/systemd-networkd

DESCRIPTION         top

       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).

       systemd-networkd will create network devices based on the
       configuration in systemd.netdev(5) files, respecting the [Match]
       sections in those files.

       systemd-networkd will manage network addresses and routes for any
       link for which it finds a .network file with an appropriate [Match]
       section, see systemd.network(5). For those links, it will flush
       existing network addresses and routes when bringing up the device.
       Any links not matched by one of the .network files will be ignored.
       It is also possible to explicitly tell systemd-networkd to ignore a
       link by using Unmanaged=yes option, see systemd.network(5).

       When systemd-networkd exits, it generally leaves existing network
       devices and configuration intact. This makes it possible to
       transition from the initramfs and to restart the service without
       breaking connectivity. This also means that when configuration is
       updated and systemd-networkd is restarted, netdev interfaces for
       which configuration was removed will not be dropped, and may need to
       be cleaned up manually.

       systemd-networkd may be introspected and controlled at runtime using
       networkctl(1).

CONFIGURATION FILES         top

       The configuration files are read from the files located in the system
       network directory /usr/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).
