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.

COMMANDS         top

       The following commands are understood:

       list [PATTERN...]
           Show a list of existing links and their status. If one ore
           more PATTERNs are specified, only links matching one of them
           are shown. 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.

           The operational status is one of the following:

           missing
               the device is missing

           off
               the device is powered down

           no-carrier
               the device is powered up, but it does not yet have a
               carrier

           dormant
               the device has a carrier, but is not yet ready for normal
               traffic

           degraded-carrier
               for bond or bridge master, one of the bonding or bridge
               slave network interfaces is in off, no-carrier, or
               dormant state

           carrier
               the link has a carrier, or for bond or bridge master, all
               bonding or bridge slave network interfaces are enslaved
               to the master

           degraded
               the link has carrier and addresses valid on the local
               link configured

           enslaved
               the link has carrier and is enslaved to bond or bridge
               master network interface

           routable
               the link has carrier and routable address configured

           The setup status is one of the following:

           pending
               udev is still processing the link, we don't yet know if
               we will manage it

           failed
               networkd failed to manage the link

           configuring
               in the process of retrieving configuration or configuring
               the link

           configured
               link configured successfully

           unmanaged
               networkd is not handling the link

           linger
               the link is gone, but has not yet been dropped by
               networkd

       status [PATTERN...]
           Show information about the specified links: type, state,
           kernel module driver, hardware and IP address, configured DNS
           servers, etc. If one ore 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
                    Address: 10.193.76.5 on eth0
                             192.168.122.1 on virbr0
                             169.254.190.105 on eth0

                             8.8.4.4

       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.

           Produces output similar to:

               LINK             CHASSIS ID        SYSTEM NAME      CAPS        PORT ID           PORT DESCRIPTION

               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[1] for a discussion of address labels.

           Produces output similar to:

               Prefix/Prefixlen                          Label

                      ::1/128                                0

       delete DEVICE...
           Deletes virtual netdevs. Takes interface name or index
           number.

       up DEVICE...
           Bring devices up. Takes interface name or index number.

       down DEVICE...
           Bring devices down. Takes interface name or index number.

       renew DEVICE...
           Renew dynamic configurations e.g. addresses received from
           DHCP server. Takes interface name or index number.

       forcerenew DEVICE...
           Send a FORCERENEW message to all connected clients,
           triggering DHCP reconfiguration. Takes interface name or
           index number.

       reconfigure DEVICE...
           Reconfigure network interfaces. Takes interface name or index
           number. Note that this does not reload .netdev or .network
           corresponding to the specified interface. So, if you edit
           config files, it is necessary to call networkctl reload first
           to apply new settings.

       reload
           Reload .netdev and .network files. If a new .netdev file is
           found, then the corresponding netdev is created. Note that
           even if an existing .netdev is modified or removed,
           systemd-networkd does not update or remove the netdev. If a
           new, modified or removed .network file is found, then all
           interfaces which match the file are reconfigured.

           When used with status, controls the number of journal lines
           to show, counting from the most recent ones. Takes a positive
