How to restart the networking after changing the network configuration?

[Zhengyu Guo]

Hi all,

My question is how to restart the networking after changing the network
configuration?

I setup a bridge in my machine and I need to restart the network to make it
work. However, If I use the following command it will not work.

~~~
/etc/network$ sudo service networking restart
Job for networking.service failed because the control process exited with
error code. See "systemctl status networking.service" and "journalctl -xe"
for details.
~~~
 But if I reboot the machine, the configuration will take effect without
any problem.

Therefore, I want to know if there are any alternative way that I can use
for restart the networking without the need for rebooting.

Thanks for any help.

Zhengyu
