       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 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:

               the device is missing

               the device is powered down

               the device is powered up, but it does not yet have a carrier

               the device has a carrier, but is not yet ready for normal traffic

               for bond or bridge master, one of the bonding or bridge slave network interfaces
               is in off, no-carrier, or dormant state

               the link has a carrier, or for bond or bridge master, all bonding or bridge slave
               network interfaces are enslaved to the master

               the link has carrier and addresses valid on the local link configured

               the link has carrier and is enslaved to bond or bridge master network interface

               the link has carrier and routable address configured

           The setup status is one of the following:

               udev is still processing the link, we don't yet know if we will manage it

               udev has processed the link, but we don't yet know if we will manage it

               in the process of retrieving configuration or configuring the link

               link configured successfully

               networkd is not handling the link

               networkd failed to manage the link

               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

           Produces output similar to:

               ‚óŹ        State: routable
                 Online state: online
                      Address: on eth0
                      on virbr0
                      on eth0
                               fe80::5054:aa:bbbb:cccc on eth0
                      Gateway: (CISCO SYSTEMS, INC.) on eth0

           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:

               all links have unknown online status (i.e. there are no required links)

               all required links are offline

               some, but not all, required links are 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 for details.

           Produces output similar to:

               s - Service VLAN, m - Two-port MAC Relay (TPMR)

               1 neighbors listed.

           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

           Produces output similar to:

       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

           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


       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.

           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.

           Print a short version string and exit.

           Do not print the legend, i.e. column headers and the footer with hints.

           Do not pipe output into a pager.


       On success, 0 is returned, a non-zero failure code otherwise.
