networkctlsystemdnetworkctl1networkctlQuery the status of network linksnetworkctlOPTIONSCOMMANDLINKDescriptionnetworkctl may be used to introspect the
state of the network links as seen by
systemd-networkd. Please refer to
systemd-networkd.service8
for an introduction to the basic concepts, functionality, and
configuration syntax.CommandsThe following commands are understood:listPATTERN…Show a list of existing links and their status. If one ore more
PATTERNs are specified, only links matching one of them are shown.
If no further arguments are specified shows all links,
otherwise just the specified links. Produces output similar to:
IDX LINK TYPE OPERATIONAL SETUP
1 lo loopback carrier unmanaged
2 eth0 ether routable configured
3 virbr0 ether no-carrier unmanaged
4 virbr0-nic ether off unmanaged
4 links listed.The operational status is one of the following:

IP address, configured DNS servers, etc. If one ore more PATTERNs are
specified, only links matching one of them are shown.When no links are specified, an overall network status is shown. Also see the option
.Produces output similar to:
● State: routable
Address: 10.193.76.5 on eth0
192.168.122.1 on virbr0
169.254.190.105 on eth0

Gateway: 10.193.11.1 (CISCO SYSTEMS, INC.) on eth0
DNS: 8.8.8.8
8.8.4.4lldpPATTERN…Show discovered LLDP (Link Layer Discovery Protocol) neighbors. If one or more
PATTERNs are specified only neighbors on those interfaces are shown.
Otherwise shows discovered neighbors on all interfaces. Note that for this feature to work,
LLDP= must be turned on for the specific interface, see
systemd.network5 for
details.Produces output similar to:

1 neighbors listed.labelShow numerical address labels that can be used for address selection.
This is the same information that
ip-addrlabel8
shows. See RFC 3484
for a discussion of address labels.Produces output similar to:

Takes interface name or index number.reconfigureReconfigure network interfaces. Takes interface name or index number.reloadReload .netdev and .network files.
If a new .netdev file is found, then the corresponding netdev is created.
Note that even if an existing .netdev is modified or removed,
systemd-networkd does not update or remove the netdev.
If a new, modified or removed .network file is found, then all interfaces
which match the file are reconfigured.OptionsThe following options are understood:Show all links with status.Show link statistics with status.Do not ellipsize the output.When used with status, controls the number of journal lines to show,
counting from the most recent ones. Takes a positive integer argument. Defaults to 10.Exit statusOn success, 0 is returned, a non-zero failure code otherwise.See Alsosystemd-networkd.service8,
