Please refer to [**systemd-networkd.service**(8)](https://www.chedong.com/phpMan.php/man/systemd-networkd.service/8/markdown) 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 or more _PATTERN_s 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. Added in version 245. off The device is powered down. Added in version 240. no-carrier The device is powered up, but does not yet have a carrier. Added in version 240. dormant The device has a carrier, but is not yet ready for normal traffic. Added in version 240. degraded-carrier One of the bonding or bridge slave network interfaces is in off, no-carrier, or dormant state, and the master interface has no address. Added in version 242. carrier The link has carrier, or for bond or bridge master, all bonding or bridge slave network interfaces are enslaved to the master. Added in version 240. degraded The link has carrier and addresses valid on the local link configured. For bond or bridge master this means that not all slave network interfaces have carrier but at least one does. Added in version 240. enslaved The link has carrier and is enslaved to bond or bridge master network interface. Added in version 242. routable The link has carrier and routable address configured. For bond or bridge master it is not necessary for all slave network interfaces to have carrier, but at least one must. Added in version 240. The setup status is one of the following: pending [**systemd-udevd**(8)](https://www.chedong.com/phpMan.php/man/systemd-udevd/8/markdown) is still processing the link, we don't yet know if we will manage it. Added in version 240. initialized [**systemd-udevd**(8)](https://www.chedong.com/phpMan.php/man/systemd-udevd/8/markdown) has processed the link, but we don't yet know if we will manage it. Added in version 251. configuring Configuration for the link is being retrieved or the link is being configured. Added in version 240. configured Link has been configured successfully. Added in version 240. unmanaged **systemd-networkd **is not handling the link. Added in version 240. failed **systemd-networkd **failed to configure the link. Added in version 240. linger The link is gone, but has not yet been dropped by **systemd-networkd**. Added in version 240. Added in version 219. **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 _PATTERN_s 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](https://www.chedong.com/phpMan.php/perldoc/fe80%3A%3A5054/markdown):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). Added in version 249. offline All required links are offline. Added in version 249. partial Some, but not all, required links are online. Added in version 249. online All required links are online. Added in version 249. Added in version 219. **lldp **[_PATTERN..._] Show discovered LLDP (Link Layer Discovery Protocol) neighbors. If one or more _PATTERN_s 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)](https://www.chedong.com/phpMan.php/man/systemd.network/5/markdown) 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. Added in version 219. ### label Show numerical address labels that can be used for address selection. This is the same information that [**ip-addrlabel**(8)](https://www.chedong.com/phpMan.php/man/ip-addrlabel/8/markdown) shows. See **RFC 3484**[1] 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 Added in version 234. **delete _**DEVICE..._ Deletes virtual netdevs. Takes interface name or index number. Added in version 243. **up _**DEVICE..._ Bring devices up. Takes interface name or index number. Added in version 246. **down _**DEVICE..._ Bring devices down. Takes interface name or index number. Added in version 246. **renew _**DEVICE..._ Renew dynamic configurations e.g. addresses received from DHCP server. Takes interface name or index number. Added in version 244. **forcerenew _**DEVICE..._ Send a FORCERENEW message to all connected clients, triggering DHCP reconfiguration. Takes interface name or index number. Added in version 246. **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. Added in version 244. ### 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. Added in version 244. **edit _**FILE_|_@DEVICE_... Edit network configuration files, which include .network, .netdev, and .link files. If no network config file matching the given name is found, a new one will be created under /etc/. Specially, if the name is prefixed by "@", it will be treated as a network interface, and editing will be performed on the network config files associated with it. Additionally, the interface name can be suffixed with ":network" (default) or ":link", in order to choose the type of network config to operate on. If **--drop-in= **is specified, edit the drop-in file instead of the main configuration file. Unless **--no-reload **is specified, **systemd-networkd **will be reloaded after the edit of the .network or .netdev files finishes. The same applies for .link files and **systemd-** [**udevd**(8)](https://www.chedong.com/phpMan.php/man/udevd/8/markdown). Note that the changed link settings are not automatically applied after reloading. To achieve that, trigger uevents for the corresponding interface. Refer to [**systemd.link**(5)](https://www.chedong.com/phpMan.php/man/systemd.link/5/markdown) for more information. Added in version 254. **cat _**FILE_|_@DEVICE_... Show network configuration files. This command honors the "@" prefix in the same way as **edit**. Added in version 254. ## OPTIONS The following options are understood: ### -a --all Show all links with **status**. Added in version 219. ### -s --stats Show link statistics with **status**. Added in version 243. ### -l --full Do not ellipsize the output. Added in version 245. ### -n --lines= 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. Added in version 245. **--drop-in=_**NAME_ When used with **edit**, edit the drop-in file _NAME_ instead of the main configuration file. Added in version 254. ### --no-reload When used with **edit**, [**systemd-networkd.service**(8)](https://www.chedong.com/phpMan.php/man/systemd-networkd.service/8/markdown) or [**systemd-udevd.service**(8)](https://www.chedong.com/phpMan.php/man/systemd-udevd.service/8/markdown) will not be reloaded after the editing finishes. Added in version 254. **--json=_**MODE_ Shows output formatted as JSON. Expects one of "short" (for the shortest possible output without any redundant whitespace or line breaks), "pretty" (for a pretty version of the same, with indentation and line breaks) or "off" (to turn off JSON output, the default). ### -h --help Print a short help text and exit. ### --version Print a short version string and exit. ### --no-legend Do not print the legend, i.e. column headers and the footer with hints. ### --no-pager Do not pipe output into a pager. ## EXIT STATUS On success, 0 is returned, a non-zero failure code otherwise. ## SEE ALSO [**systemd-networkd.service**(8)](https://www.chedong.com/phpMan.php/man/systemd-networkd.service/8/markdown), [**systemd.network**(5)](https://www.chedong.com/phpMan.php/man/systemd.network/5/markdown), [**systemd.netdev**(5)](https://www.chedong.com/phpMan.php/man/systemd.netdev/5/markdown), [**ip**(8)](https://www.chedong.com/phpMan.php/man/ip/8/markdown) ## NOTES 1.
