General Status
nmcli general status
Show All Connections
nmcli con[nection] show
Show All Devices
To show devices recognized by NetworkManager and their state:
nmcli dev[ice] show
nmcli dev[ice] status
Configuration Changes
Changes made with nmcli do not require a reload but do require the associated interface to be put down and then up again as follows:
nmcli dev disconnect <interface-name> nmcli con up <interface-name>
Adding a Static Ethernet Connection
nmcli connection add type ethernet con-name <connection-name> ifname <interface-name> ip4 <address> gw4 <address>
Note that a connection with the same name exists, NetworkManager will add another one, so you will end up with two connections with the same name. It is best if the existing one is either deleted, modified or edited.
Example:
mcli con del eth0 nmcli con add type ethernet con-name eth0 ifname eth0 ip4 172.30.0.4/16 gw4 172.30.0.1
Adding a Dynamic Ethernet Connection
Same as adding the static one, but without specifying the ip/gateway:
nmcli connection add type ethernet con-name <connection-name> ifname <interface-name>
