   for an introduction to the basic concepts, functionality, and
   configuration syntax.

COMMANDS

   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 --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
                Gateway: 10.193.11.1 (CISCO SYSTEMS, INC.) on eth0
                    DNS: 8.8.8.8
                         8.8.4.4

   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 systemd.network(5) for
       details.

       Produces output similar to:

           LINK             CHASSIS ID        SYSTEM NAME      CAPS        PORT ID           PORT DESCRIPTION
