During runtime only the binary database is used.
- Network Link Configuration
- Network link configuration is performed by the net_setup_link
- udev builtin.
-
- The link 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.
- Link files must have the extension .link; other extensions are ignored.
- All link 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 link file with a local file if needed;
- a symlink in /etc with the same name as a link file in
- /usr/lib, pointing to /dev/null,
- disables the link file entirely.
-
- The link file contains a [Match] section, which
- determines if a given link file may be applied to a given device; and a
- [Link] section specifying how the device should be
- configured. The first (in lexical order) of the link files that matches
- a given device is applied.
-
- A link 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=
-
- The persistent path, as exposed by the udev property ID_PATH.
- May contain shell style globs.
-
-
-
- Driver=
-
- 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=
-
- The device type, as exposed by the udev property DEVTYPE.
-
-
-
- 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.
-
-
-
-
- The [Link] section accepts the following keys:
-
-
-
- Description=
-
- A description of the device.
-
-
-
- Alias=
-
- The ifalias is set to this value.
-
-
-
- MACAddressPolicy=
-
- The policy by which the MAC address should be set. The
- available policies are:
-
-
-
- persistent
-
- If the hardware has a persistent MAC address, as most
- hardware should, and this is used by the kernel, nothing is
- done. Otherwise, a new MAC address is generated which is
- guaranteed to be the same on every boot for the given
- machine and the given device, but which is otherwise random.
-
-
-
-
- random
-
- If the kernel is using a random MAC address, nothing is
- done. Otherwise, a new address is randomly generated each
- time the device appears, typically at boot.
-
-
-
-
-
-
-
- MACAddress=
-
- The MAC address to use, if no MACAddressPolicy=
- is specified.
-
-
-
-
- NamePolicy=
-
- An ordered, space-separated list of policies by which the
- interface name should be set. NamePolicy may
- be disabled by specifying net.ifnames=0 on the
- kernel commandline. Each of the policies may fail, and the first
- successful one is used. The name is not set directly, but
- is exported to udev as the property ID_NET_NAME,
- which is, by default, used by a udev rule to set
- NAME. The available policies are:
-
-
-
- database
-
- The name is set based on entries in the Hardware
- Database with the key
- ID_NET_NAME_FROM_DATABASE.
-
-
-
-
- onboard
-
- The name is set based on information given by the
- firmware for on-board devices, as exported by the udev
- property ID_NET_NAME_ONBOARD.
-
-
-
-
- slot
-
- The name is set based on information given by the
- firmware for hot-plug devices, as exported by the udev
- property ID_NET_NAME_SLOT.
-
-
-
-
- path
-
- The name is set based on the device's physical location,
- as exported by the udev property
- ID_NET_NAME_PATH.
-
-
-
-
- mac
-
- The name is set based on the device's persistent MAC
- address, as exported by the udev property
- ID_NET_NAME_MAC.
-
-
-
-
-
-
-
- Name=
-
- The interface name to use in case all the policies specified
- in NamePolicy= fail, or in case
- NamePolicy= is missing or disabled.
-
-
-
-
- MTUBytes=
-
- The maximum transmission unit in bytes to set for the device.
-
-
-
- BitsPerSecond=
-
- The speed to set for the device, the value is rounded down
- to the nearest Mbps.
-
-
-
- Duplex=
-
- The duplex mode to set for the device. The accepted values
- are half and full.
-
-
-
-
- WakeOnLan=
-
- The Wake-on-LAN policy to set for the device. The supported
- values are:
-
-
