NETWORKCTL(1)                     networkctl                     NETWORKCTL(1)

NAME
       networkctl - Query the status of network links

SYNOPSIS
       networkctl [OPTIONS...] COMMAND [LINK...]

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.

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
                    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

                        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.

       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.

       delete
           Deletes virtual netdevs. Takes interface name or index number.

       renew
           Renew dynamic configurations e.g. addresses received from DHCP
           server. 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.

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.

       -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.

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