## e.g. new network interface (enp0s9) added to the system

[root@rhel7mgmt1 ~]# nmcli device status
DEVICE      TYPE      STATE         CONNECTION
enp0s3      ethernet  connected     enp0s3    
virbr0      bridge    connected     virbr0    
enp0s8      ethernet  connected     enp0s8    
enp0s9      ethernet  disconnected  --        
lo          loopback  unmanaged     --        
virbr0-nic  tun       unmanaged     --


## activate the connection

[root@rhel7mgmt1 ~]# nmcli con add con-name enp0s9 type ethernet ifname enp0s9
Connection 'enp0s9' (155866d3-4ce7-4d71-8ca9-c6d709be6e03) successfully added.


## then define the IP addresses and set method to manual

[root@rhel7mgmt1 ~]# nmcli con mod enp0s9 ipv4.addresses "192.168.1.30/24"

[root@rhel7mgmt1 ~]# nmcli con mod enp0s9 ipv4.method manual

[root@rhel7mgmt1 ~]# nmcli con show
