Имя (Name)
networkctl - Query the status of network links
Синопсис (Synopsis)
networkctl [OPTIONS...] COMMAND [LINK...]
Описание (Description)
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.
Команды (Commands)
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
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
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.
Параметры (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.
Статус выхода (Exit)
On success, 0 is returned, a non-zero failure code otherwise.
