networkctl systemd networkctl 1 networkctl Query the status of network links networkctl OPTIONS COMMAND LINK Description networkctl may be used to introspect the state of the network links as seen by systemd-networkd. Please refer to systemd-networkd.service8 for an introduction to the basic concepts, functionality, and configuration syntax. Commands 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: 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 . 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 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.network5 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-addrlabel8 shows. See RFC 3484 for a discussion of address labels. Produces output similar to: Prefix/Prefixlen Label ::/0 1 fc00::/7 5 fec0::/10 11 2002::/16 2 3ffe::/16 12 2001:10::/28 7 2001::/32 6 ::ffff:0.0.0.0/96 4 ::/96 3 ::1/128 0 delete Deletes virtual netdevs. Takes interface name or index number. renew Renew dynamic configurations e.g. addresses received from DHCP server. Takes interface name or index number. reconfigure Reconfigure network interfaces. Takes interface name or index number. 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. Options The following options are understood: Show all links with status. Show link statistics with status. Do not ellipsize the output. When used with status, controls the number of journal lines to show, counting from the most recent ones. Takes a positive integer argument. Defaults to 10. Exit status On success, 0 is returned, a non-zero failure code otherwise. See Also systemd-networkd.service8, systemd.network5, systemd.netdev5, ip8
