<li><p><strong><code>set-name</code></strong> (scalar)</p>
<blockquote>
<p>When matching on unique properties such as path or MAC, or with
additional assumptions such as “there will only ever be one Wi-Fi
device”, match rules can be written so that they only match one device.
Then this property can be used to give that device a more specific or
desirable name than the default from udev ifnames. Any additional device
that satisfies the match rules will then fail to get renamed and keep
the original kernel name (and <code>dmesg</code> will show an
error).</p>
</blockquote></li>
<li><p><strong><code>wakeonlan</code></strong> (boolean)</p>
<blockquote>
<p>Enable wake on LAN. Off by default.</p>
</blockquote></li>
<li><p><strong><code>emit-lldp</code></strong> (boolean) – since
0.99</p>
<blockquote>
<p>(networkd back end only) Whether to emit LLDP packets. Off by
default.</p>
</blockquote></li>
<li><p><strong><code>receive-checksum-offload</code></strong> (boolean)
– since 0.104</p>
<blockquote>
<p>(networkd back end only) If set to <code>true</code>
(<code>false</code>), the hardware offload for checksumming of ingress
network packets is enabled (disabled). When unset, the kernel’s default
will be used.</p>
</blockquote></li>

This property can be specified globally in <code>network:</code>, for a
device type (in e.g. <code>ethernets:</code>) or for a particular device

<code>sriov</code>. If a VLAN is defined with the <code>sriov</code>
renderer for an SR-IOV Virtual Function interface, this causes Netplan
to set up a hardware VLAN filter for it. There can be only one defined
per VF.</p>
</blockquote></li>
<li><p><strong><code>dhcp4</code></strong> (boolean)</p>
<blockquote>
<p>Enable DHCP for IPv4. Off by default.</p>

<li><p><strong><code>dhcp6</code></strong> (boolean)</p>
<blockquote>
<p>Enable DHCP for IPv6. Off by default. This covers both stateless DHCP
- where the DHCP server supplies information like DNS name servers but
not the IP address - and stateful DHCP, where the server provides both
the address and the other information.</p>
<p>If you are in an IPv6-only environment with completely stateless
auto-configuration (SLAAC with RDNSS), this option can be set to cause
the interface to be brought up. (Setting <code>accept-ra</code> alone is
not sufficient.) Auto-configuration will still honour the contents of
the router advertisement and only use DHCP if requested in the RA.</p>
<p>Note that <strong><code>rdnssd</code></strong>(8) is required to use
RDNSS with networkd. No extra software is required for
NetworkManager.</p>
</blockquote></li>
<li><p><strong><code>ipv6-mtu</code></strong> (scalar) – since 0.98 >

needing to set this is an unusual requirement. > >
<strong>Requires feature: <code>ipv6-mtu</code></strong></p></li>
<li><p><strong><code>ipv6-privacy</code></strong> (boolean)</p>
<blockquote>
<p>Enable IPv6 Privacy Extensions (RFC 4941) for the specified
interface, and prefer temporary addresses. Defaults to false - no
privacy extensions. There is currently no way to have a private address
but prefer the public address.</p>
</blockquote></li>
<li><p><strong><code>link-local</code></strong> (sequence of
scalars)</p>
<blockquote>
<p>Configure the link-local addresses to bring up. Valid options are
<code>ipv4</code> and <code>ipv6</code>, which respectively allow
enabling IPv4 and IPv6 link local addressing. If this field is not
defined, the default is to enable only IPv6 link-local addresses. If the
field is defined but configured as an empty set, IPv6 link-local
addresses are disabled as well as IPv4 link- local addresses.</p>
<p>This feature enables or disables link-local addresses for a protocol,
but the actual implementation differs per back end. On networkd, this
directly changes the behaviour and may add an extra address on an
interface. When using the NetworkManager back end, enabling link-local
has no effect if the interface also has DHCP enabled.</p>
</blockquote>
<p>Examples:</p>
<ul>
<li>Enable only IPv4 link-local: <code>link-local: [ ipv4 ]</code></li>
<li>Enable all link-local addresses:
<code>link-local: [ ipv4, ipv6 ]</code></li>
<li>Disable all link-local addresses: <code>link-local: [ ]</code></li>
</ul></li>
<li><p><strong><code>ignore-carrier</code></strong> (boolean) – since

<blockquote>
<p>(networkd back end only) Allow the specified interface to be
configured even if it has no carrier.</p>
</blockquote></li>
<li><p><strong><code>critical</code></strong> (boolean)</p>
<blockquote>
<p>Designate the connection as “critical to the system”, meaning that
special care will be taken by to not release the assigned IP when the
daemon is restarted. (not recognised by NetworkManager)</p>
</blockquote></li>
<li><p><strong><code>dhcp-identifier</code></strong> (scalar)</p>
<blockquote>
<p>(networkd back end only) Sets the source of DHCP (v4) client
identifier. If <code>mac</code> is specified, the MAC address of the
link is used. If this option is omitted, or if <code>duid</code> is
specified, networkd will generate an RFC4361-compliant client identifier
for the interface by combining the link’s IAID and DUID.</p>
</blockquote></li>
<li><p><strong><code>dhcp4-overrides</code></strong> (mapping)</p>
<blockquote>
<p>(networkd back end only) Overrides default DHCP behaviour; see the
<code>DHCP Overrides</code> section below.</p>
</blockquote></li>
<li><p><strong><code>dhcp6-overrides</code></strong> (mapping)</p>
<blockquote>
<p>(networkd back end only) Overrides default DHCP behaviour; see the
<code>DHCP Overrides</code> section below.</p>
</blockquote></li>
<li><p><strong><code>accept-ra</code></strong> (boolean)</p>
<blockquote>
<p>Accept Router Advertisement that would have the kernel configure IPv6
by itself. When enabled, accept Router Advertisements. When disabled, do
not respond to Router Advertisements. If unset use the host kernel
default setting.</p>
</blockquote></li>
<li><p><strong><code>addresses</code></strong> (sequence of scalars and
mappings)</p>
<blockquote>
<p>Add static addresses to the interface in addition to the ones
received through DHCP or RA. Each sequence entry is in CIDR notation,
i.e. of the form <code>addr/prefixlen</code>. <code>addr</code> is an
IPv4 or IPv6 address as recognised by
<strong><code>inet_pton</code></strong>(3) and <code>prefixlen</code>
the number of bits of the subnet.</p>
<p>For virtual devices (bridges, bonds, VLAN) if there is no address
configured and DHCP is disabled, the interface may still be brought
online, but will not be addressable from the network.</p>
<p>In addition to the addresses themselves one can specify configuration
parameters as mappings. Current supported options are:</p>
</blockquote>
<ul>
<li><p><strong><code>lifetime</code></strong> (scalar) – since 0.100</p>
<blockquote>
<p>Default: <code>forever</code>. This can be <code>forever</code> or
<code>0</code> and corresponds to the <code>PreferredLifetime</code>
option in the <code>Address</code> section of
<code>systemd-networkd</code>. Currently supported on the networkd back
end only.</p>
</blockquote></li>
<li><p><strong><code>label</code></strong> (scalar) – since 0.100</p>

<p>Overrides only have an effect if the corresponding <code>dhcp4</code>
or <code>dhcp6</code> is set to <code>true</code>.</p>
<p>If both <code>dhcp4</code> and <code>dhcp6</code> are
<code>true</code>, the networkd back end requires that
<code>dhcp4-overrides</code> and <code>dhcp6-overrides</code> contain
the same keys and values. If the values do not match, an error will be
shown and the network configuration will not be applied.</p>
<p>When using the NetworkManager back end, different values may be

<h2 id="routing">Routing</h2>
<p>Complex routing is possible with Netplan. Standard static routes as
well as policy routing using routing tables are supported via the
networkd back end.</p>
<p>These options are available for all types of interfaces.</p>
<h3 id="default-routes">Default routes</h3>
<p>The most common need for routing concerns the definition of default
routes to reach the wider internet. Those default routes can only
defined once per IP family and routing table. A typical example would
look like the following:</p>

<h2 id="properties-for-device-type-ethernets">Properties for device type
<code>ethernets</code></h2>
<p><strong><code>Status</code></strong>: Optional.</p>
<p><strong><code>Purpose</code></strong>: Use the <code>ethernets</code>
key to configure Ethernet interfaces.</p>
<p><strong><code>Structure</code></strong>: The key consists of a
mapping of Ethernet interface IDs. Each <code>ethernet</code> has a
number of configuration options. You don’t need to define each interface
by their name inside the <code>ethernets</code> mapping. You can use any
ID that describes the interface and match the actual network card using
the <code>match</code> key. The general configuration structure for
Ethernet is shown below.</p>
<div class="sourceCode" id="cb14"><pre

<p><code>device-id</code> is the interface identifier. If you use the
interface name as the ID, Netplan will match that interface.</p>
<p>Consider the example below. In this case, an interface called
<code>eth0</code> will be configured with DHCP.</p>

<p>The <code>device-id</code> can be any descriptive name your find

behaviour.</p>
</blockquote>
<ul>
<li><p><strong><code>mode</code></strong> (scalar)</p>
<blockquote>
<p>Set the bonding mode used for the interfaces. The default is
<code>balance-rr</code> (round robin). Possible values are
<code>balance-rr</code>, <code>active-backup</code>,
<code>balance-xor</code>, <code>broadcast</code>, <code>802.3ad</code>,

</blockquote></li>
<li><p><strong><code>arp-interval</code></strong> (scalar)</p>
<blockquote>
<p>Set the interval value for how frequently ARP link monitoring should
happen. The default value is <code>0</code>, which disables ARP
monitoring. For the networkd back end, this maps to the

the value will be interpreted as milliseconds.</p>
</blockquote></li>
<li><p><strong><code>arp-ip-targets</code></strong> (sequence of
scalars)</p>
<blockquote>
<p>IP addresses of other hosts on the link which should be sent ARP
requests in order to validate that a port is up. This option is only

used for <code>active-backup</code> mode when <code>arp-validate</code>
is enabled. Possible values are <code>any</code> and
<code>all</code>.</p>
</blockquote></li>
<li><p><strong><code>up-delay</code></strong> (scalar)</p>
<blockquote>
<p>Specify the delay before enabling a link once the link is physically
up. The default value is <code>0</code>. This maps to the
<code>UpDelaySec=</code> property for the networkd renderer. This option

specified, the value will be interpreted as milliseconds.</p>
</blockquote></li>
<li><p><strong><code>down-delay</code></strong> (scalar)</p>
<blockquote>
<p>Specify the delay before disabling a link once the link has been
lost. The default value is <code>0</code>. This maps to the

0.106</p>
<blockquote>
<p>In <code>balance-rr</code> mode, specifies the number of packets to
transmit on a port before switching to the next. When this value is set
to <code>0</code>, ports are chosen at random. Allowable values are
between <code>0</code> and <code>65535</code>. The default value is
<code>1</code>. This setting is only used in <code>balance-rr</code>

<p>Alias: <strong><code>packets-per-slave</code></strong>
<!--- wokeignore:rule=slave --></p>
</blockquote></li>
<li><p><strong><code>primary-reselect-policy</code></strong>

active port, the system will use this policy to decide how the new
active port will be chosen and how recovery will be handled. The
possible values are <code>always</code>, <code>better</code> and
<code>failure</code>.</p>
</blockquote></li>
<li><p><strong><code>resend-igmp</code></strong> (scalar)</p>
<blockquote>
<p>In modes <code>balance-rr</code>, <code>active-backup</code>,

membership reports. Otherwise, the first membership report is sent on
failover and subsequent reports are sent at 200ms intervals.</p>
</blockquote></li>
<li><p><strong><code>learn-packet-interval</code></strong> (scalar)</p>
<blockquote>
<p>Specify the interval between sending learning packets to each port.
The value range is between <code>1</code> and <code>0x7fffffff</code>.
The default value is <code>1</code>. This option only affects
<code>balance-tlb</code> and <code>balance-alb</code> modes. Using the
networkd renderer, this field maps to the
<code>LearnPacketIntervalSec=</code> property. If no time suffix is
specified, the value will be interpreted as seconds.</p>
</blockquote></li>
<li><p><strong><code>primary</code></strong> (scalar)</p>
<blockquote>
<p>Specify a device to be used as a primary port, or preferred device to
use as a port for the bond (i.e. the preferred device to send data
through), whenever it is available. This only affects

<p>When applied, a virtual interface called <code>tunnel0</code> will be
created in the system. Its operation mode is defined by the property
<code>mode</code>.</p>
<p>Tunnels allow traffic to pass as if it was between systems on the
same local network, although systems may be far from each other but
reachable via the Internet. They may be used to support IPv6 traffic on
a network where the ISP does not provide the service, or to extend and
“connect” separate local networks. See <a
href="https://en.wikipedia.org/wiki/Tunneling_protocol">Tunneling_protocol</a>
for more general information about tunnels.</p>
<p>The specific settings for tunnels are defined below.</p>
<ul>
<li><p><strong><code>mode</code></strong> (scalar)</p>
<blockquote>
<p>Defines the tunnel mode. Valid options are <code>sit</code>,
<code>gre</code>, <code>ip6gre</code>, <code>ipip</code>,
<code>ipip6</code>, <code>ip6ip6</code>, <code>vti</code>,
<code>vti6</code>, <code>wireguard</code>, <code>vxlan</code>,
<code>gretap</code> and <code>ip6gretap</code> modes. In addition, the
<code>NetworkManager</code> back end supports <code>isatap</code>
tunnels.</p>
</blockquote></li>
<li><p><strong><code>local</code></strong> (scalar)</p>
<blockquote>
<p>Defines the address of the local endpoint of the tunnel. (For VXLAN)
This should match one of the parent’s IP addresses or make use of the
networkd special values.</p>
</blockquote></li>
<li><p><strong><code>remote</code></strong> (scalar)</p>
<blockquote>
<p>Defines the address of the remote endpoint of the tunnel or multicast
group IP address for VXLAN.</p>
</blockquote></li>
<li><p><strong><code>ttl</code></strong> (scalar) – since 0.103</p>
<blockquote>
<p>Defines the Time To Live (TTL) of the tunnel. Takes a number in the
range <code>1..255</code>.</p>
</blockquote></li>
<li><p><strong><code>key</code></strong> (scalar or mapping)</p>
<blockquote>
<p>Define keys to use for the tunnel. The key can be a number or a
dotted quad (an IPv4 address). For <code>wireguard</code> it can be a
base64-encoded private key or (as of networkd v242+) an absolute path to
a file, containing the private key (since 0.100). It is used for
identification of IP transforms. This is only required for
<code>vti</code> and <code>vti6</code> when using the networkd back
end.</p>
<p>This field may be used as a scalar (meaning that a single key is
specified and to be used for input, output and private key), or as a
mapping, where you can further specify
<code>input</code>/<code>output</code>/<code>private</code>.</p>
</blockquote>
<ul>
<li><p><strong><code>input</code></strong> (scalar)</p>

</blockquote></li>
<li><p><strong><code>private</code></strong> (scalar) – since 0.100</p>
<blockquote>
<p>A base64-encoded private key required for WireGuard tunnels. When the
<code>systemd-networkd</code> back end (v242+) is used, this can also be
an absolute path to a file containing the private key.</p>
</blockquote></li>
<li><p><strong><code>private-key-flags</code></strong> (sequence of
scalars) – since 0.107</p>
<blockquote>
<p>Private key flags used by NetworkManager. Possible values are:
<code>agent-owned</code>, <code>not-saved</code> and
<code>not-required</code>.</p>
<p><code>agent-owned</code>: a user-session secret agent is responsible
for providing and storing this secret.</p>
<p><code>not-saved</code>: this secret should not be saved but should be
requested from the user each time it is required.</p>
<p><code>not-required</code>: this flag hints that the secret is not

<p><strong>Purpose</strong>: Use the <code>virtual-ethernets</code> key
to create virtual Ethernet interfaces.</p>
<p><strong>Structure</strong>: The key consists of a mapping of
<code>veth</code> interface names. Each <code>veth</code> requires a
<code>peer</code>. In order to have a fully working <code>veth</code>
pair, both devices must be defined, i.e., only setting the
<code>peer</code> key with the peer name is not enough, the peer
interface must also be defined and set the first one as its peer. The
general configuration structure for virtual Ethernet is shown below.</p>

<p>When applied, two virtual interfaces called <code>veth0</code> and
<code>veth1</code> will be created in the system.</p>
<p>Virtual Ethernet devices act as tunnels forwarding traffic from one
interface to the other. They can be used to connect two separate virtual
networks such as network namespaces and bridges. It’s not possible to
move <code>virtual-ethernets</code> to different namespaces through
Netplan at the present moment.</p>
<p>The specific settings for <code>virtual-ethernets</code> are defined
below.</p>
<ul>
<li><p><strong><code>peer</code></strong> (scalar)</p>
<blockquote>
<p>Defines the <code>virtual-ethernet</code> peer. The peer interface
must also be a <code>virtual-ethernet</code> device.</p>
</blockquote></li>
</ul>
<p>Below is a complete example that uses a pair of virtual Ethernet
devices to create a link between two bridges:</p>
