COMMANDS¶
The following commands are understood:
list [PATTERN...]
Show a list of existing links and their status. If one or
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
one of the bonding or bridge slave network interfaces is
in off, no-carrier, or dormant state, and the master interface has no
address.
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. For bond or bridge master this means that not all slave
network interfaces have carrier but at least one does.
enslaved
the link has carrier and is enslaved to bond or bridge
master network interface
routable
the link has carrier and routable address configured. For
bond or bridge master it is not necessary for all slave network interfaces to
have carrier, but at least one must.
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
initialized
udev has processed the link, but we don't yet know if we
will manage it
configuring
in the process of retrieving configuration or configuring
the link
configured
link configured successfully
unmanaged
networkd is not handling the link
failed
networkd failed to manage 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 or 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
Online state: online
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
In the overall network status, the online state depends on the
individual online state of all required links. Managed links are required
for online by default. In this case, the online state is one of the
following:
unknown
all links have unknown online status (i.e. there are no
required links)
offline
all required links are offline
partial
some, but not all, required links are online
online
all required links are online
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 DEVICE...
Deletes virtual netdevs. Takes interface name or index
number.
up DEVICE...
Bring devices up. Takes interface name or index
number.
down DEVICE...
Bring devices down. Takes interface name or index
number.
renew DEVICE...
Renew dynamic configurations e.g. addresses received from
DHCP server. Takes interface name or index number.
forcerenew DEVICE...
Send a FORCERENEW message to all connected clients,
triggering DHCP reconfiguration. Takes interface name or index number.
reconfigure DEVICE...
Reconfigure network interfaces. Takes interface name or
index number. Note that this does not reload .netdev or .network corresponding
to the specified interface. So, if you edit config files, it is necessary to
call networkctl reload first to apply new settings.
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.
OPTIONS¶
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.
--json=MODE
Shows output formatted as JSON. Expects one of
"short" (for the shortest possible output without any redundant
whitespace or line breaks), "pretty" (for a pretty version of the
same, with indentation and line breaks) or "off" (to turn off JSON
output, the default).
-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.
