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:

               ‚óŹ      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

               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

       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.
