Point 1: View all the saved connections
# nmcli connection show
ens1f0 XXXX-XXXX-XXXX-XXXX-XXXX ethernet ens1f0
ens1f1 YYYY-YYYY-YYYY-YYYY-YYYY ethernet ens1f1
ens10f0 ZZZZ-ZZZZ-ZZZZ-ZZZZ-ZZZZ ethernet --
ens10f1 AAAA-AAAA-AAAA-AAAA-AAAA ethernet --
Point 2a: Stop Network
You can use the command “nmcli connection down ssid/uuid". For example
# nmcli connection down XXXX-XXXX-XXXX-XXXX-XXXX
Connection 'eno0' successfully deactivated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/3)
Point 2b: Start Network
You can use the command “nmcli connection up ssid/uuid". For example
# nmcli connection up XXXX-XXXX-XXXX-XXXX-XXXX
Connection 'eno0' successfully activated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/3)
Point 3: Device Connection
To check the Device status
# nmcli dev status
ens1f0 ethernet connected ens1f0
eno1f1 ethernet connected ens1f1
eno10f0 ethernet disconnected --
eno10f1 ethernet disconnected --
