networkd

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

               ●        State: routable
                 Online state: online
                      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

           In the overall network status, the online state depends on the individual online state of all required links. Managed links are required for online by default. In this case, the online state is one of the
           following:

           unknown
               all links have unknown online status (i.e. there are no required links)

           offline
               all required links are offline

           partial
               some, but not all, required links are online

           online
               all required links are online

       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.

               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.
