NAME         top

       networkctl - Query the status of network links

SYNOPSIS         top

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

DESCRIPTION         top

       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.

OPTIONS         top

       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

COMMANDS         top

       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,

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

           Produces output similar to:

               ●      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

           Produces output similar to:

               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 labels.
