       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 options are understood:

       -a --all
           Show all links with status.

       -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.


       The following commands are understood:

       list [LINK...]
           Show a list of existing links and their status. 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.

       status [LINK...]
           Show information about the specified links: type, state, kernel module driver,
           hardware and IP address, configured DNS servers, etc.

           When no links are specified, an overall network status is shown. Also see the option

           Produces output similar to:

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

       lldp [LINK...]
           Show discovered LLDP (Link Layer Discovery Protocol) neighbors. If one or more link
           names 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 on the specific interface, see 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.

           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:

               Prefix/Prefixlen                          Label
                       ::/0                                  1

                   2001::/32                                 6
               ::ffff:                             4
                       ::/96                                 3
                      ::1/128                                0


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