<h1 id="overview">Overview</h1>
<p>The <code>network</code> role enables users to configure network on
the target machines. This role can be used to configure:</p>
<ul>
<li>Ethernet interfaces</li>
<li>Bridge interfaces</li>
<li>Bonded interfaces</li>
<li>VLAN interfaces</li>
<li>MacVLAN interfaces</li>
<li>Infiniband interfaces</li>
<li>Wireless (WiFi) interfaces</li>
<li>IP configuration</li>
<li>802.1x authentication</li>
</ul>
<h1 id="introduction">Introduction</h1>
<p>The <code>network</code> role supports two providers: <code>nm</code>
and <code>initscripts</code>. <code>nm</code> is used by default since
RHEL7 and <code>initscripts</code> in RHEL6. The
<code>initscripts</code> provider requires <code>network-scripts</code>
package which is deprecated in RHEL8 and dropped in RHEL9. These
providers can be configured per host via the <a
href="#variables"><code>network_provider</code></a> variable. In absence
of explicit configuration, it is autodetected based on the distribution.
However, note that either <code>nm</code> or <code>initscripts</code> is
not tied to a certain distribution. The <code>network</code> role works
everywhere the required API is available. This means that
<code>nm</code> requires at least NetworkManager's API version 1.2
available and certain settings supported by <code>nm</code> provider
also requires higher NetworkManager's API version since which the
settings are introduced.</p>
<p>The <code>network</code> role supports two modules:
<code>network_connections</code> and <code>network_state</code>.</p>
<p>For each host a list of networking profiles can be configured via the
<code>network_connections</code> variable.</p>
<ul>
<li><p>For <code>initscripts</code>, profiles correspond to ifcfg files
in the <code>/etc/sysconfig/network-scripts/</code> directory and those
ifcfg files has the line <code>NM_CONTROLLED=no</code> written.</p></li>
<li><p>For <code>nm</code>, profiles correspond to connection profiles
are handled by NetworkManager and only NetworkManager keyfile format
profiles are supported in
<code>/etc/NetworkManager/system-connections/</code> since
RHEL9.</p></li>
</ul>
<p>For each host the network state configuration can also be applied to
the interface directly via the <code>network_state</code> variable, and
only the <code>nm</code> provider supports using the
<code>network_state</code> variable.</p>
<p>Note that the <code>network</code> role both operates on the
connection profiles of the devices (via the
<code>network_connections</code> variable) and on devices directly (via
the <code>network_state</code> variable). When configuring the
connection profiles through the role, it uses the profile name by
default as the interface name. It is also possible to create generic
profiles, by creating for example a profile with a certain IP
configuration without activating the profile. To apply the configuration
to the actual networking interface, use the <code>nmcli</code> commands
on the target system.</p>
<p><strong>Warning</strong>: The <code>network</code> role updates or
creates all connection profiles on the target system as specified in the
<code>network_connections</code> variable. Therefore, the
<code>network</code> role removes options from the specified profiles if
the options are only present on the system but not in the
<code>network_connections</code> variable. Exceptions are mentioned
below. However, the partial networking configuration can be achieved via
specifying the network state configuration in the
<code>network_state</code> variable.</p>
<h1 id="requirements">Requirements</h1>
<p>See below</p>
<h2 id="collection-requirements">Collection requirements</h2>
<p>The role requires external collections only for management of
<code>rpm-ostree</code> nodes. Please run the following command to
install them if you need to manage <code>rpm-ostree</code> nodes:</p>

<h1 id="variables">Variables</h1>
<p>The <code>network</code> role is configured via variables starting
with <code>network_</code> as the name prefix. List of variables:</p>
<ul>
<li><code>network_provider</code> - The <code>network_provider</code>
variable allows to set a specific provider (<code>nm</code> or
<code>initscripts</code>) . Setting it to
<code>{{ network_provider_os_default }}</code>, the provider is set
depending on the operating system. This is usually <code>nm</code>
except for RHEL 6 or CentOS 6 systems. Changing the provider for an
existing profile is not supported. To switch providers, it is
recommended to first remove profiles with the old provider and then
create new profiles with the new provider.</li>
<li><code>network_connections</code> - The connection profiles are
configured as <code>network_connections</code>, which is a list of
dictionaries that include specific options.</li>
<li><code>network_allow_restart</code> - It defaults to
<code>false</code>. To load NetworkManager plugins after installation,
NetworkManager requires to be restarted. For example, if a wireless
connection is configured and NetworkManager-wifi is not installed,
NetworkManager must be restarted prior to the connection being
configured. The restart can result in connectivity loss and therefore
the role does not allow it without explicit consent. The user can
consent to it by setting <code>network_allow_restart</code> to
<code>true</code>. Setting <code>network_allow_restart</code> to
<code>false</code> will prevent the role from restarting
NetworkManager.</li>
<li><code>network_state</code> - The network state settings can be
configured in the managed host, and the format and the syntax of the
configuration should be consistent with the <a
href="https://nmstate.io/examples.html">nmstate state examples</a>
(YAML).</li>
</ul>

<h1 id="network_connections-options">network_connections Options</h1>
<p>The <code>network_connections</code> variable is a list of
dictionaries that include the following options. List of options:</p>
<h2 id="name-usually-required"><code>name</code> (usually required)</h2>
<p>The <code>name</code> option identifies the connection profile to be
configured. It is not the name of the networking interface for which the
profile applies, though we can associate the profile with an interface
and give them the same name. Note that you can have multiple profiles
for the same device, but only one profile can be active on the device
each time. For NetworkManager, a connection can only be active at one
device each time.</p>
<ul>
<li><p>For <code>NetworkManager</code>, the <code>name</code> option
corresponds to the <a
href="https://developer.gnome.org/NetworkManager/stable/nm-settings.html#nm-settings.property.connection.id"><code>connection.id</code></a>
property option. Although NetworkManager supports multiple connections
with the same <code>connection.id</code>, the <code>network</code> role
cannot handle a duplicate <code>name</code>. Specifying a
<code>name</code> multiple times refers to the same connection
profile.</p></li>
<li><p>For <code>initscripts</code>, the <code>name</code> option
determines the ifcfg file name
<code>/etc/sysconfig/network-scripts/ifcfg-$NAME</code>. Note that the
<code>name</code> does not specify the <code>DEVICE</code> but a
filename. As a consequence, <code>'/'</code> is not a valid character
for the <code>name</code>.</p></li>
</ul>
<p>You can also use the same connection profile multiple times.
Therefore, it is possible to create a profile and activate it
separately.</p>
<p><strong>Note:</strong> The network role will only change the profiles
that are specified in the <code>network_connections</code> variable.
Therefore, if only the ports of a profile are specified to be removed
from the controller and the controller is not specified, then the
controller profile will remain on the system. This can happen, if for
example all ports are removed from a bond interface.</p>
<p><strong>Note:</strong> To remove all profiles on a system that are
not specified in the <code>network_connections</code> variable, add an
entry without a name and <code>persistent_state: absent</code>. This
will match and remove all remaining profiles:</p>

<h2 id="state"><code>state</code></h2>
<p>The <code>state</code> option identifies what is the runtime state of
each connection profile. The <code>state</code> option (optional) can be
set to the following values:</p>
<ul>
<li><code>up</code> - the connection profile is activated</li>
<li><code>down</code> - the connection profile is deactivated</li>
</ul>
<h3 id="state-up"><code>state: up</code></h3>
<ul>
<li><p>For <code>NetworkManager</code>, this corresponds to
<code>nmcli connection id {{name}} up</code>.</p></li>
<li><p>For <code>initscripts</code>, this corresponds to
<code>ifup {{name}}</code>.</p></li>
</ul>
<p>When the <code>state</code> option is set to <code>up</code>, you can
also specify the <code>wait</code> option (optional):</p>
<ul>
<li><code>wait: 0</code> - initiates only the activation, but does not
wait until the device is fully connected. The connection will be
completed in the background, for example after a DHCP lease was
received.</li>
<li><code>wait: <seconds></code> is a timeout that enables you to
decide how long you give the device to activate. The default is using a
suitable timeout. Note that the <code>wait</code> option is only
supported by NetworkManager.</li>
</ul>
<p>Note that <code>state: up</code> always re-activates the profile and
possibly changes the networking configuration, even if the profile was
already active before. As a consequence, <code>state: up</code> always
changes the system.</p>
<h3 id="state-down"><code>state: down</code></h3>
<ul>
<li><p>For <code>NetworkManager</code>, it corresponds to
<code>nmcli connection id {{name}} down</code>.</p></li>
<li><p>For <code>initscripts</code>, it corresponds to call
<code>ifdown {{name}}</code>.</p></li>
</ul>
<p>You can deactivate a connection profile, even if is currently not
active. As a consequence, <code>state: down</code> always changes the
system.</p>
<p>Note that if the <code>state</code> option is unset, the connection
profile's runtime state will not be changed.</p>
<h2 id="persistent_state"><code>persistent_state</code></h2>
<p>The <code>persistent_state</code> option identifies if a connection
profile is persistent (saved on disk). The <code>persistent_state</code>
option can be set to the following values:</p>
<h3
id="persistent_state-present-default"><code>persistent_state: present</code>
(default)</h3>
<p>Note that if <code>persistent_state</code> is <code>present</code>
and the connection profile contains the <code>type</code> option, the
profile will be created or updated. If the connection profile is
incomplete (no <code>type</code> option), the behavior is undefined.
Also, the <code>present</code> value does not directly result in a
change in the network configuration. If the <code>state</code> option is
not set to <code>up</code>, the profile is only created or modified, not
activated.</p>
<p>For NetworkManager, the new connection profile is created with the
<code>autoconnect</code> option enabled by default. Therefore,
NetworkManager can activate the new profile on a currently disconnected
device. (<a
href="https://bugzilla.redhat.com/show_bug.cgi?id=1401515">rh#1401515</a>).</p>
<h3
id="persistent_state-absent"><code>persistent_state: absent</code></h3>
<p>The <code>absent</code> value ensures that the profile is not present
on the target host. If a profile with the given <code>name</code>
exists, it will be deleted. In this case:</p>
<ul>
<li><p><code>NetworkManager</code> deletes all connection profiles with
the corresponding <code>connection.id</code>. Deleting a profile usually
does not change the current networking configuration, unless the profile
was currently activated on a device. Deleting the currently active
connection profile disconnects the device. That makes the device
eligible to autoconnect another connection (for more details, see <a
href="https://bugzilla.redhat.com/show_bug.cgi?id=1401515">rh#1401515</a>).</p></li>
<li><p><code>initscripts</code> deletes the ifcfg file in most cases
with no impact on the runtime state of the system unless some component
is watching the sysconfig directory.</p></li>
</ul>
<p><strong>Note</strong>: For profiles that only contain a
<code>state</code> option, the <code>network</code> role only activates
or deactivates the connection without changing its configuration.</p>
<h2 id="type"><code>type</code></h2>
<p>The <code>type</code> option can be set to the following values:</p>
<ul>
<li><code>ethernet</code></li>
<li><code>bridge</code></li>
<li><code>bond</code></li>
<li><code>team</code></li>
<li><code>vlan</code></li>
<li><code>macvlan</code></li>
<li><code>infiniband</code></li>
<li><code>wireless</code></li>
<li><code>dummy</code></li>
</ul>
<h3 id="type-ethernet"><code>type: ethernet</code></h3>
<p>If the type is <code>ethernet</code>, then there can be an extra
<code>ethernet</code> dictionary with the following items (options):
<code>autoneg</code>, <code>speed</code> and <code>duplex</code>, which
correspond to the settings of the <code>ethtool</code> utility with the
same name.</p>
<ul>
<li><code>autoneg</code>: <code>true</code> (default) or
<code>false</code> [if auto-negotiation is enabled or disabled]</li>
<li><code>speed</code>: speed in Mbit/s</li>
<li><code>duplex</code>: <code>half</code> or <code>full</code></li>
</ul>
<p>Note that the <code>speed</code> and <code>duplex</code> link
settings are required when autonegotiation is disabled
(<code>autoneg: false</code>).</p>
<h3 id="type-bridge-type-bond-type-team"><code>type: bridge</code>,
<code>type: bond</code>, <code>type: team</code></h3>
<p>The <code>bridge</code>, <code>bond</code>, <code>team</code> device
types work similar. Note that <code>team</code> is not supported in
RHEL6 kernels, and has been deprecated in RHEL 9.</p>
<p>For ports, the <code>port_type</code> and <code>controller</code>
properties must be set. Note that ports should not have <code>ip</code>
settings, which means that the active ports will not have IP addresses
assigned.</p>
<p>The <code>controller</code> refers to the <code>name</code> of a
profile in the Ansible playbook. It is neither an interface-name nor a
connection-id of NetworkManager.</p>
<ul>
<li><p>For NetworkManager, <code>controller</code> will be converted to
the <code>connection.uuid</code> of the corresponding profile.</p></li>
<li><p>For initscripts, the controller is looked up as the
<code>DEVICE</code> from the corresponding ifcfg file.</p></li>
</ul>
<p>As <code>controller</code> refers to other profiles of the same or
another play, the order of the <code>connections</code> list matters.
Profiles that are referenced by other profiles need to be specified
first. Also, <code>--check</code> ignores the value of the
<code>controller</code> and assumes it will be present during a real
run. That means, in presence of an invalid <code>controller</code>,
<code>--check</code> may signal success but the actual play run
fails.</p>
<p>If only bringing down the <code>controller</code> profile , then the
port profiles will be brought down automatically. If bringing down the
connection on some or all ports, then the controller profile stay
active.</p>
<p>The <code>team</code> type uses <code>roundrobin</code> as the
<code>runner</code> configuration. No further configuration is supported
at the moment.</p>
<h3 id="type-vlan"><code>type: vlan</code></h3>
<p>Similar to <code>controller</code>, the <code>parent</code>
references the connection profile in the ansible role. The vlan ID can
be specified by using nested vlan setting, the valid vlan ID value
ranges from 0 to 4094. Here is how to specify the vlan ID:</p>
<div class="sourceCode" id="cb5"><pre
class="sourceCode yaml"><code class="sourceCode yaml"><span id="cb5-1"><a href="#cb5-1" aria-hidden="true" tabindex="-1"></a><span class="fu">type</span><span class="kw">:</span><span class="at"> vlan</span></span>
<span id="cb5-2"><a href="#cb5-2" aria-hidden="true" tabindex="-1"></a><span class="fu">vlan</span><span class="kw">:</span></span>
<span id="cb5-3"><a href="#cb5-3" aria-hidden="true" tabindex="-1"></a><span class="at"> </span><span class="fu">id</span><span class="kw">:</span><span class="at"> </span><span class="dv">6</span></span></code></pre></div>
<h3 id="type-macvlan"><code>type: macvlan</code></h3>
<p>Similar to <code>controller</code> and <code>vlan</code>, the
<code>parent</code> references the connection profile in the ansible
role.</p>
<h3 id="type-infiniband"><code>type: infiniband</code></h3>
<p>For the infiniband connection, currently it is only supported for the
nm provider, and the following options are supported:</p>
<ul>
<li><code>p_key</code>: The infiniband P_Key to use for the device. When
it is not specified, then the connection is created on the physical
infiniband fabrics. Otherwise, it is a 16-bit unsigned integer and the
ipoib (IP over Infiniband) connection will be created, the high bit
should be set if it is a "full membership" P_Key. The special
<code>p_key</code> values 0x0000 and 0x8000 are invalid as kernel does
not support them.</li>
<li><code>transport_mode</code>: The ipoib (IP over Infiniband)
connection operation mode. The possible modes are <code>datagram</code>
(default) and <code>connected</code>.</li>
</ul>
<p><strong>Note:</strong> If the <code>p_key</code> is specified , then
the <code>interface_name</code> must be unset.</p>
<h3 id="type-wireless"><code>type: wireless</code></h3>
<p>The <code>wireless</code> type supports WPA-PSK (password)
authentication, WPA-EAP (802.1x) authentication, WPA3-Personal SAE
(password) authentication and Enhanced Open (OWE).</p>
<p><code>nm</code> (NetworkManager) is the only supported
<code>network_provider</code> for this type.</p>
<p>If WPA-EAP is used, ieee802_1x settings must be defined in the <a
href="#ieee802_1x">ieee802_1x</a> option.</p>
<p>The following options are supported:</p>
<ul>
<li><p><code>ssid</code>: the SSID of the wireless network
(required)</p></li>
<li><p><code>key_mgmt</code> (required)</p>
<p>Any key from following key list:</p>
<ul>
<li><code>owe</code></li>
<li><code>sae</code></li>
<li><code>wpa-eap</code></li>
<li><code>wpa-psk</code></li>
</ul></li>
<li><p><code>password</code>: password for the network (required if
<code>wpa-psk</code> or <code>sae</code> is used)</p></li>
</ul>
<h3 id="type-dummy"><code>type: dummy</code></h3>
<p>Dummy network interface, <code>nm</code> (NetworkManager) is the only
supported <code>network_provider</code> for this type.</p>
<h2 id="autoconnect"><code>autoconnect</code></h2>
<p>By default, profiles are created with autoconnect enabled.</p>
<ul>
<li><p>For <code>NetworkManager</code>, this corresponds to the
<code>connection.autoconnect</code> property.</p></li>
<li><p>For <code>initscripts</code>, this corresponds to the
<code>ONBOOT</code> property.</p></li>
</ul>
<h2 id="mac"><code>mac</code></h2>
<p>The <code>mac</code> address is optional and restricts the profile to
be usable only on devices with the given MAC address. <code>mac</code>
is only allowed for <code>type</code> <code>ethernet</code> or
<code>infiniband</code> to match a non-virtual device with the profile.
The value of the <code>mac</code> address needs to be specified in
hexadecimal notation using colons (for example:
<code>mac: "00:00:5e:00:53:5d"</code>). To avoid YAML parsing mac
addresses as integers in sexagesimal (base 60) notation (see <a
href="https://yaml.org/spec/1.1/#id858600">https://yaml.org/spec/1.1/#id858600</a>),
it is recommended to always quote the value with double quotes and
sometimes it is necessary.</p>
<ul>
<li><p>For <code>NetworkManager</code>, <code>mac</code> is the
permanent MAC address, <code>ethernet.mac-address</code>.</p></li>
<li><p>For <code>initscripts</code>, <code>mac</code> is the currently
configured MAC address of the device (<code>HWADDR</code>).</p></li>
</ul>
<h2 id="cloned_mac"><code>cloned_mac</code></h2>
<p>The <code>cloned_mac</code> address is optional and allow to specify
the strategy to get the default mac or to set your own mac. The value of
the <code>cloned_mac</code> address needs to be specified in hexadecimal
notation like <code>mac</code> property. Besides explicitly specifying
the value as a MAC address with hexadecimal notation, the following
special values are also supported:</p>
<ul>
<li><code>default</code>: honor the default behavior in
NetworkManager</li>
<li><code>permanent</code>: use the permanent MAC address of the
device</li>
<li><code>preserve</code>: don't change the MAC address of the device
upon activation</li>
<li><code>random</code>: generate a randomized value upon each
connect</li>
<li><code>stable</code>: generate a stable, hashed MAC address</li>
</ul>
<h2 id="mtu"><code>mtu</code></h2>
<p>The <code>mtu</code> option denotes the maximum transmission unit for
the profile's device. The maximum value depends on the device. For
virtual devices, the maximum value of the <code>mtu</code> option
depends on the underlying device.</p>
<h2 id="interface_name"><code>interface_name</code></h2>
<p>For the <code>ethernet</code> and <code>infiniband</code> types, the
<code>interface_name</code> option restricts the profile to the given
interface by name. This argument is optional and by default the profile
name is used unless a mac address is specified using the
<code>mac</code> key. Specifying an empty string (<code>""</code>) means
that the profile is not restricted to a network interface.</p>
<p><strong>Note:</strong> With <a
href="https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/Networking_Guide/ch-Consistent_Network_Device_Naming.html">persistent
interface naming</a>, the interface is predictable based on the hardware
configuration. Otherwise, the <code>mac</code> address might be an
option.</p>
<p>For virtual interface types such as bridges, the
<code>interface_name</code> is the name of the created interface. In
case of a missing <code>interface_name</code>, the <code>name</code> of
the profile name is used.</p>
<p><strong>Note:</strong> The <code>name</code> (the profile name) and
the <code>interface_name</code> (the device name) may be different or
the profile may not be tied to an interface at all.</p>
<h2 id="match"><code>match</code></h2>
<p>Settings to specify devices or systems matching a profile. Currently,
only the <code>path</code> setting is implemented.</p>
<p>The settings support a list of patterns which support the following
modifiers and wildcards:</p>
<p><strong>Special modifiers for <code>match</code>
settings:</strong></p>
<ul>
<li><p><code>|</code>, the element is an alternative, the match
evaluates to be true if at least one of the alternatives matches
(logical OR). By default, an element is an alternative. This means that
an element <code>foo</code> behaves the same as
<code>|foo</code></p></li>
<li><p><code>&</code>, the element is mandatory, the match evaluates
to be true if all the element matches (logical AND)</p></li>
<li><p><code>!</code>, an element can also be inverted with exclamation
mark (<code>!</code>) between the pipe symbol (or the ampersand) and
before the pattern. Note that <code>!foo</code> is a shortcut for the
mandatory match <code>&!foo</code></p></li>
<li><p><code>\</code>, a backslash can be used at the beginning of the
element (after the optional special characters) to escape the start of
the pattern. For example, <code>&\!a</code> is an mandatory match
for literally <code>!a</code></p></li>
</ul>
<p><strong>Wildcard patterns for <code>match</code> Settings:</strong>
In general these work like shell globs.</p>
<ul>
<li><code>*</code>, matches zero or more of any character</li>
<li><code>?</code>, matches any single character</li>
<li><code>[fo]</code> - matches any single <code>f</code> or
<code>o</code> character - also supports ranges - <code>[0-9]</code>
will match any single digit character</li>
</ul>
<h2 id="path"><code>path</code></h2>
<p>The <code>path</code> setting is a list of patterns to match against
the <code>ID_PATH</code> udev property of devices. The
<code>ID_PATH</code> udev property represents the persistent path of a
device. It consists of a subsystem string (pci, usb, platform, etc.) and
a subsystem-specific identifier. The <code>ID_PATH</code> of a device
can be obtained with the command
<code>udevadm info /sys/class/net/$dev | grep ID_PATH=</code> or by
looking at the <code>path</code> property exported by NetworkManager
(<code>nmcli -f general.path device show $dev</code>). The
<code>path</code> setting is optional and restricts the profile to be
activated only on devices with a matching <code>ID_PATH</code>. The
<code>path</code> setting is only supported for ethernet or infiniband
profiles. It supports modifiers and wildcards as described for match
settings.</p>
<h2 id="zone"><code>zone</code></h2>
<p>The <code>zone</code> option sets the firewalld zone for the
interface.</p>
<p>Ports to the bridge, bond or team devices cannot specify a zone.</p>
<h2 id="ip"><code>ip</code></h2>
<p>The IP configuration supports the following options:</p>
<ul>
<li><p><code>address</code> Manual addressing can be specified via a
list of addresses under the <code>address</code> option.</p></li>
<li><p><code>auto_gateway</code></p>
<p>If enabled, a default route will be configured using the default
gateway. If disabled, the default route will be removed.</p>
<p>If this variable is not specified, the role will use the default
behavior of the <code>network_provider</code> selected.</p>
<p>Setting this option to <code>false</code> is equivalent to:</p>
<ul>
<li><code>DEFROUTE = no</code> in initscripts, or</li>
<li><code>ipv4.never-default/ipv6.never-default yes</code> in nmcli</li>
</ul></li>
<li><p><code>dhcp4</code>, <code>auto6</code>, and
<code>ipv6_disabled</code></p>
<p>Also, manual addressing can be specified by setting either
<code>dhcp4</code> or <code>auto6</code>. The <code>dhcp4</code> key is
for DHCPv4 and <code>auto6</code> for StateLess Address Auto
Configuration (SLAAC). Note that the <code>dhcp4</code> and
<code>auto6</code> keys can be omitted and the default key depends on
the presence of manual addresses. <code>ipv6_disabled</code> can be set
to disable ipv6 for the connection.</p></li>
<li><p><code>dhcp4_send_hostname</code></p>
<p>If <code>dhcp4</code> is enabled, it can be configured whether the
DHCPv4 request includes the hostname via the
<code>dhcp4_send_hostname</code> option. Note that
<code>dhcp4_send_hostname</code> is only supported by the
<code>nm</code> provider and corresponds to <a
href="https://developer.gnome.org/NetworkManager/stable/nm-settings.html#nm-settings.property.ipv4.dhcp-send-hostname"><code>ipv4.dhcp-send-hostname</code></a>
property.</p></li>
<li><p><code>dns</code></p>
<p>Manual DNS configuration can be specified via a list of addresses
given in the <code>dns</code> option.</p></li>
<li><p><code>dns_search</code></p>
<p>Manual DNS configuration can be specified via a list of domains to
search given in the <code>dns_search</code> option.</p></li>
<li><p><code>dns_options</code></p>
<p><code>dns_options</code> is only supported for the NetworkManager
provider. Manual DNS configuration via a list of DNS options can be
given in the <code>dns_options</code>. The list of supported DNS options
for IPv4 nameservers is described in <a
href="https://man7.org/linux/man-pages/man5/resolv.conf.5.html">man 5
resolv.conf</a>. Currently, the list of supported DNS options is:</p>
<ul>
<li><code>attempts:n</code></li>
<li><code>debug</code></li>
<li><code>edns0</code></li>
<li><code>inet6</code></li>
<li><code>ip6-bytestring</code></li>
<li><code>ip6-dotint</code></li>
<li><code>ndots:n</code></li>
<li><code>no-aaaa</code></li>
<li><code>no-check-names</code></li>
<li><code>no-ip6-dotint</code></li>
<li><code>no-reload</code></li>
<li><code>no-tld-query</code></li>
<li><code>rotate</code></li>
<li><code>single-request</code></li>
<li><code>single-request-reopen</code></li>
<li><code>timeout:n</code></li>
<li><code>trust-ad</code></li>
<li><code>use-vc</code></li>
</ul>
<p><strong>Note:</strong> The "trust-ad" setting is only honored if the
profile contributes name servers to resolv.conf, and if all contributing
profiles have "trust-ad" enabled. When using a caching DNS plugin
(dnsmasq or systemd-resolved in NetworkManager.conf) then "edns0" and
"trust-ad" are automatically added.</p></li>
<li><p><code>dns_priority</code></p>
<p>DNS servers priority. The relative priority for DNS servers specified
by this setting. The default value is 0, a lower numerical value has
higher priority. The valid value of <code>dns_priority</code> ranges
from -2147483648 to 2147483647. Negative values have the special effect
of excluding other configurations with a greater numerical priority
value; so in presence of at least one negative priority, only DNS
servers from connections with the lowest priority value will be
used.</p></li>
<li><p><code>gateway4</code> and <code>gateway6</code></p>
<p>The default gateway for IPv4 (<code>gateway4</code>) or IPv6
(<code>gateway6</code>) packets.</p></li>
<li><p><code>ipv4_ignore_auto_dns</code> and
<code>ipv6_ignore_auto_dns</code></p>
<p>If enabled, the automatically configured name servers and search
domains (via DHCPv4, DHCPv6, modem etc) for IPv4 or IPv6 are ignored,
only the name servers and search domains specified in <code>dns</code>
and <code>dns_search</code> properties are used. The settings are
distinguished by the address families. The variables are not supported
by initscripts provider.</p>
<p>If the variables are not specified, the role will use the default
behavior of nm provider.</p></li>
<li><p><code>route_metric4</code> and <code>route_metric6</code></p>
<p>For <code>NetworkManager</code>, <code>route_metric4</code> and
<code>route_metric6</code> corresponds to the <a
href="https://developer.gnome.org/NetworkManager/stable/nm-settings.html#nm-settings.property.ipv4.route-metric"><code>ipv4.route-metric</code></a>
and <a
href="https://developer.gnome.org/NetworkManager/stable/nm-settings.html#nm-settings.property.ipv6.route-metric"><code>ipv6.route-metric</code></a>
properties, respectively. If specified, it determines the route metric
for DHCP assigned routes and the default route, and thus the priority
for multiple interfaces. For <code>initscripts</code>,
<code>route_metric4</code> sets the metric for the default route and
<code>route_metric6</code> is not supported.</p></li>
<li><p><code>route</code></p>
<p>Static route configuration can be specified via a list of routes
given in the <code>route</code> option. The default value is an empty
list. Each route is a dictionary with the following entries:
<code>gateway</code>, <code>metric</code>, <code>network</code>,
<code>prefix</code>, <code>src</code>, <code>table</code> and
<code>type</code>. <code>network</code> and <code>prefix</code> specify
the destination network. <code>src</code> specifies the source IP
address for a route. <code>table</code> supports both the numeric table
and named table. In order to specify the named table, the users have to
ensure the named table is properly defined in
<code>/etc/iproute2/rt_tables</code> or
<code>/etc/iproute2/rt_tables.d/*.conf</code>. The optional
<code>type</code> key supports the values <code>blackhole</code>,
<code>prohibit</code>, and <code>unreachable</code>. See <a
href="https://man7.org/linux/man-pages/man8/ip-route.8.html#DESCRIPTION">man
8 ip-route</a> for their definition. Routes with these types do not
support a gateway. If the type is not specified, the route is considered
as a unicast route. Note that the classless inter-domain routing(CIDR)
notation or the network mask notation are not supported for the
<code>network</code> key.</p></li>
<li><p><code>routing_rule</code></p>
<p>The policy routing rules can be specified via a list of rules given
in the <code>routing_rule</code> option, which allow routing the packets
on other packet fields except for destination address. The default value
is a an empty list. Each rule is a dictionary with the following
entries:</p>
<ul>
<li><code>priority</code> - The priority of the rule. A valid priority
ranges from 0 to 4294967295. Higher number means lower priority.</li>
<li><code>action</code> - The action of the rule. The possible values
are <code>to-table</code> (default), <code>blackhole</code>,
<code>prohibit</code>, <code>unreachable</code>.</li>
<li><code>dport</code>- The range of the destination port (e.g.
<code>1000 - 2000</code>). A valid dport value for both start and end
ranges from 0 to 65534. And the start cannot be greater than the
end.</li>
<li><code>family</code> - The IP family of the rule. The possible values
are <code>ipv4</code> and <code>ipv6</code>.</li>
<li><code>from</code> - The source address of the packet to match (e.g.
<code>192.168.100.58/24</code>).</li>
<li><code>fwmark</code> - The fwmark value of the packet to match.</li>
<li><code>fwmask</code> - The fwmask value of the packet to match.</li>
<li><code>iif</code> - Select the incoming interface name to match.</li>
<li><code>invert</code> - Invert the selected match of the rule. The
possible values are boolean values <code>true</code> and
<code>false</code> (default). If the value is <code>true</code>, this is
equivalent to match any packet that not satisfying selected match of the
rule.</li>
<li><code>ipproto</code> - Select the IP protocol value to match, the
valid value ranges from 1 to 255.</li>
<li><code>oif</code> - Select the outgoing interface name to match.</li>
<li><code>sport</code> - The range of the source port (e.g.
<code>1000 - 2000</code>). A valid sport value for both start and end
ranges from 0 to 65534. And the start cannot be greater than the
end.</li>
<li><code>suppress_prefixlength</code> - Reject routing decisions that
have a prefix length of the specified or less.</li>
<li><code>table</code> - The route table to look up for the
<code>to-table</code> action. <code>table</code> supports both the
numeric table and named table. In order to specify the named table, the
users have to ensure the named table is properly defined in
<code>/etc/iproute2/rt_tables</code> or
<code>/etc/iproute2/rt_tables.d/*.conf</code>.</li>
<li><code>to</code> - The destination address of the packet to match
(e.g. <code>192.168.100.58/24</code>).</li>
<li><code>tos</code> - Select the tos value to match.</li>
<li><code>uid</code> - The range of the uid to match (e.g.
<code>1000 - 2000</code>). A valid uid value for both start and end
ranges from 0 to 4294967295. And the start cannot be greater than the
end.</li>
</ul></li>
<li><p><code>route_append_only</code></p>
<p>The <code>route_append_only</code> option allows only to add new
routes to the existing routes on the system.</p>
<p>If the <code>route_append_only</code> boolean option is set to
<code>true</code>, the specified routes are appended to the existing
routes. If <code>route_append_only</code> is set to <code>false</code>
(default), the current routes are replaced. Note that setting
<code>route_append_only</code> to <code>true</code> without setting
<code>route</code> has the effect of preserving the current static
routes.</p></li>
<li><p><code>rule_append_only</code></p>
<p>The <code>rule_append_only</code> boolean option allows to preserve
the current routing rules.</p></li>
</ul>
<p><strong>Note:</strong> When <code>route_append_only</code> or
<code>rule_append_only</code> is not specified, the network role deletes
the current routes or routing rules.</p>
<p><strong>Note:</strong> Ports to the bridge, bond or team devices
cannot specify <code>ip</code> settings.</p>
<h2 id="ethtool"><code>ethtool</code></h2>
<p>The ethtool settings allow to enable or disable various features. The
names correspond to the names used by the <code>ethtool</code> utility.
Depending on the actual kernel and device, changing some options might
not be supported.</p>
<p>The ethtool configuration supports the following options:</p>
<ul>
<li><p><code>ring</code></p>
<p>Changes the <code>rx</code>/<code>tx</code> <code>ring</code>
parameters of the specified network device. The list of supported
<code>ring</code> parameters is:</p>
<ul>
<li><code>rx</code> - Changes the number of ring entries for the Rx
ring.</li>
<li><code>rx-jumbo</code> - Changes the number of ring entries for the
Rx Jumbo ring.</li>
<li><code>rx-mini</code> - Changes the number of ring entries for the Rx
Mini ring.</li>
<li><code>tx</code> - Changes the number of ring entries for the Tx
ring.</li>
</ul></li>
