NETWORKCTL(1) networkctl NETWORKCTL(1)
networkctl - Query the status of network links
networkctl [OPTIONS...] COMMAND [LINK...]
networkctl may be used to introspect the state of the network links
as seen by systemd-networkd. Please refer to
systemd-networkd.service(8) for an introduction to the basic
concepts, functionality, and configuration syntax.
The following commands are understood:
list [PATTERN...]
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:
missing
the device is missing
off
the device is powered down
no-carrier
the device is powered up, but it does not yet have a carrier
dormant
the device has a carrier, but is not yet ready for normal
traffic
degraded-carrier
for bond or bridge master, one of the bonding or bridge slave
network interfaces is in off, no-carrier, or dormant state
carrier
the link has a carrier, or for bond or bridge master, all
bonding or bridge slave network interfaces are enslaved to
the master.
degraded
the link has carrier and addresses valid on the local link
configured
enslaved
the link has carrier and is enslaved to bond or bridge master
network interface
routable
the link has carrier and routable address configured
The setup status is one of the following:
pending
udev is still processing the link, we don't yet know if we
will manage it
failed
networkd failed to manage the link
configuring
in the process of retrieving configuration or configuring the
link
configured
link configured successfully
unmanaged
networkd is not handling the link
linger
the link is gone, but has not yet been dropped by networkd
status [PATTERN...]
Show information about the specified links: type, state, kernel
module driver, hardware and 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 --all.
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
fe80::5054:aa:bbbb:cccc on eth0
Gateway: 10.193.11.1 (CISCO SYSTEMS, INC.) on eth0
DNS: 8.8.8.8
8.8.4.4
lldp [PATTERN...]
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.network(5) for
details.
Produces output similar to:
LINK CHASSIS ID SYSTEM NAME CAPS PORT ID PORT DESCRIPTION
enp0s25 00:e0:4c:00:00:00 GS1900 ..b........ 2 Port #2
Capability Flags:
o - Other; p - Repeater; b - Bridge; w - WLAN Access Point; r - Router;
t - Telephone; d - DOCSIS cable device; a - Station; c - Customer VLAN;
s - Service VLAN, m - Two-port MAC Relay (TPMR)
1 neighbors listed.
label
Show numerical address labels that can be used for address
selection. This is the same information that ip-addrlabel(8)
shows. See RFC 3484[1] for a discussion of address labels.
Produces output similar to:
Prefix/Prefixlen Label
::/0 1
fc00::/7 5
fec0::/10 11
2002::/16 2
3ffe::/16 12
2001:10::/28 7
2001::/32 6
::ffff:0.0.0.0/96 4
::/96 3
::1/128 0
delete
Deletes virtual netdevs. Takes interface name or index number.
up
Bring devices up. Takes interface name or index number.
down
Bring devices down. Takes interface name or index number.
renew
Renew dynamic configurations e.g. addresses received from DHCP
server. Takes interface name or index number.
forcerenew
Send a FORCERENEW message to all connected clients, triggering
DHCP reconfiguration. Takes interface name or index number.
reconfigure
Reconfigure network interfaces. Takes interface name or index
number.
reload
Reload .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.
The following options are understood:
-a --all
Show all links with status.
-s --stats
Show link statistics with status.
-l, --full
Do not ellipsize the output.
-n, --lines=
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.
-h, --help
Print a short help text and exit.
--version
Print a short version string and exit.
--no-legend
Do not print the legend, i.e. column headers and the footer with
hints.
--no-pager
Do not pipe output into a pager.
On success, 0 is returned, a non-zero failure code otherwise.
