How to restart network services on Sierra?

Question

On FreeBSD/Linux, it is possible to restart network services by restarting a daemon.

Is there something similar in macOS Sierra?

You can tear down and start up the network interface using:

sudo ifconfig en0 down
sudo ifconfig en0 up

Network interfaces can also be Disabled & Enabled in System Preferences‑Network.

If you've got some extra bridge and filter interfaces along with your main network service, make them inactive as well.

The restarts Wi-Fi without sudo. Does anyone know how to do this with a single command?

networksetup -setairportpower en0 off
networksetup -setairportpower en0 on

Create a shell script with those two lines, or use Automator to create an application from a shell script with those two lines. I just did the latter, seems to work fine.

You can perhaps use && like so: networksetup -setairportpower en0 off && networksetup -setairportpower en0 on for single command.
