It detects and configures network\ndevices as they appear, as well as creating virtual network devices.\n\nTo configure low-level link settings independently of networks, see systemd.link(5).\n\nsystemd-networkd will create network devices based on the configuration in systemd.netdev(5)\nfiles, respecting the [Match] sections in those files.\n\nsystemd-networkd will manage network addresses and routes for any link for which it finds a\n.network file with an appropriate [Match] section, see systemd.network(5). For those links,\nit will flush existing network addresses and routes when bringing up the device. Any links\nnot matched by one of the .network files will be ignored. It is also possible to explicitly\ntell systemd-networkd to ignore a link by using Unmanaged=yes option, see systemd.network(5).\n\nWhen systemd-networkd exits, it generally leaves existing network devices and configuration\nintact. This makes it possible to transition from the initramfs and to restart the service\nwithout breaking connectivity. This also means that when configuration is updated and\nsystemd-networkd is restarted, netdev interfaces for which configuration was removed will not\nbe dropped, and may need to be cleaned up manually.\n\nsystemd-networkd may be introspected and controlled at runtime using networkctl(1).\n\n### CONFIGURATION FILES\n\nThe configuration files are read from the files located in the system network directory\n/lib/systemd/network, the volatile runtime network directory /run/systemd/network and the\nlocal administration network directory /etc/systemd/network.\n\nNetworks are configured in .network files, see systemd.network(5), and virtual network\ndevices are configured in .netdev files, see systemd.netdev(5).\n\n### SEE ALSO\n\nnetworkctl(1), systemd(1), systemd.link(5), systemd.network(5), systemd.netdev(5), systemd-\nnetworkd-wait-online.service(8), systemd-network-generator.service(8)\n\n\n\nsystemd 249                                                              SYSTEMD-NETWORKD.SERVICE(8)\n\n"
