Setting up 802.1x auth using command line in Ubuntu

My company’s network has 802.1x auth. So I need to auth my network.Today we using the nmcli tool to set up network.

which nmcli
nmcli con edit eth0
nmcli> set ipv4.method auto
nmcli> set 802-1x.eap peap
nmcli> set 802-1x.identity USERNAME
nmcli> set 802-1x.phase2-auth mschapv2
nmcli> save
nmcli> quit

Now the system had created a new config file. The path is /etc/NetworkManager/system-connections/eth0

Then we edit it 
sudo vim /etc/NetworkManager/system-connections/eth0
[connection]
id=CONNECTION_NAME

[802-1x]
password=YOUR_8021X_PASSWORD

Save the file and close it. Restart NetworkManager to pick up the changes

systemctl restart NetworkManager  
or 
nmcli con down eth0
nmcli con up eth0
