The following options are understood:

`-a` `--all`

  Show all links with status.

`-h`, `--help`

  Print a short help text and exit.

`--version`

  Print a short version string and exit.

`--no-legend`

`--no-pager`

  Do not pipe output into a pager.

## 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
      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.

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 for a discussion of address labels.

  Produces output similar to:

      Prefix/Prefixlen                          Label
              ::/0                                  1
