All configuration files + are collectively sorted and processed in lexical order, regardless + of the directories in which they live. However, files with + identical filenames replace each other. Files in + /etc have the highest priority, files in + /run take precedence over files with the same + name in /usr/lib. This can be used to + override a system-supplied configuration file with a local file if + needed; a symlink in /etc with the same name + as a configuration file in /usr/lib, pointing + to /dev/null, disables the configuration file + entirely. + + + + + [Match] Section Options + + The network file contains a [Match] + section, which determines if a given network file may be applied + to a given device; and a [Network] section + specifying how the device should be configured. The first (in + lexical order) of the network files that matches a given device + is applied. + + A network file is said to match a device if each of the + entries in the [Match] section matches, or if + the section is empty. The following keys are accepted: + + + + MACAddress= + + The hardware address. + + + + Path= + + A whitespace-separated list of shell-style globs + matching the persistent path, as exposed by the udev + property ID_PATH. + + + + Driver= + + A whitespace-separated list of shell-style globs + matching the driver currently bound to the device, as + exposed by the udev property DRIVER + of its parent device, or if that is not set the driver + as exposed by ethtool -i of the + device itself. + + + + Type= + + A whitespace-separated list of shell-style globs + matching the device type, as exposed by the udev property + DEVTYPE. + + + + Name= + + A whitespace-separated list of shell-style globs + matching the device name, as exposed by the udev property + INTERFACE. + + + + Host= + + Matches against the hostname or machine ID of the + host. See ConditionHost= in + systemd.unit5 + for details. + + + + + Virtualization= + + Checks whether the system is executed in a virtualized + environment and optionally test whether it is a specific + implementation. See ConditionVirtualization= in + systemd.unit5 + for details. + + + + + KernelCommandLine= + + Checks whether a specific kernel command line option is + set (or if prefixed with the exclamation mark unset). See + ConditionKernelCommandLine= in + systemd.unit5 + for details. + + + + + Architecture= + + Checks whether the system is running on a specific + architecture. See ConditionArchitecture= in + systemd.unit5 + for details. + + + + + + + + + [Link] Section Options + + The [Link] section accepts the following keys: + + + + MACAddress= + + The hardware address. + + + + MTUBytes= + + The maximum transmission unit in bytes to set for the + device. The usual suffixes K, M, G, are supported and are + understood to the base of 1024. + + + + + + + [Network] Section Options + + The [Network] section accepts the following keys: + + + + Description= + + A description of the device. This is only used for + presentation purposes. + + + + DHCP= + + Enables DHCPv4 and/or DHCPv6 support. Accepts + yes, no, + ipv4, or ipv6. + + + + DHCPServer= + + A boolean. Enables a basic DHCPv4 server on the + device. Mostly useful for handing out leases to container + instances. + + + + LinkLocalAddressing= + + Enables link-local address autoconfiguration. Accepts + yes, no, + ipv4, or ipv6. Defaults to + ipv6. + + + + IPv4LLRoute= + + A boolean. When true, sets up the route needed for + non-IPv4LL hosts to communicate with IPv4LL-only hosts. Defaults + to false. + + + + + IPv6Token= + + An IPv6 address with the top 64 bits unset. When set, indicates the + 64 bits interface part of SLAAC IPv6 addresses for this link. By default + it is autogenerated. + + + + LLMNR= + + A boolean or resolve. When true, enables + Link-Local Multicast Name Resolution on the link, when set to + resolve only resolution is enabled, but not + announcement. Defaults to true. + + + + LLDP= + + A boolean. When true, enables LLDP link receive support. + + + + + Address= + + A static IPv4 or IPv6 address and its prefix length, + separated by a / character. Specify + this key more than once to configure several addresses. + The format of the address must be as described in + inet_pton3. + This is a short-hand for an [Address] section only + containing an Address key (see below). This option may be + specified more than once. + + + If the specified address is 0.0.0.0 (for IPv4) or + [::] (for IPv6), a new address range of the requested size + is automatically allocated from a system-wide pool of + unused ranges. The allocated range is checked against all + current network interfaces and all known network + configuration files to avoid address range conflicts. The + default system-wide pool consists of 192.168.0.0/16, + 172.16.0.0/12 and 10.0.0.0/8 for IPv4, and fc00::/7 for + IPv6. This functionality is useful to manage a large + number of dynamically created network interfaces with the + same network configuration and automatic address range + assignment. + + + + + Gateway= + + The gateway address, which must be in the format + described in + inet_pton3. + This is a short-hand for a [Route] section only containing + a Gateway key.

This option may be specified more than once. + + + + IPForward= + Configures IP forwarding for the network + interface. If enabled incoming packets on the network + interface will be forwarded to other interfaces according to + the routing table. Takes either a boolean argument, or the + values ipv4 or ipv6, + which only enables IP forwarding for the specified address + family. + + + IPMasquerade= + Configures IP masquerading for the network + interface.
