nmcli is the cli for network manager which is the new way to configure network and network adaptors in Redhat/Centos 7 and Fedora 21
Here are some basic nmcli commands to get you going.
The nice thing with nmcli is that you can tab through all options ie you don't need to remember all the commands, tab completion will bring them up.
nmcli hitting tab here brings up the following options
con -- NetworkManager connections
dev -- devices managed by NetworkManager
nm -- NetworkManager status
nmcli dev hitting tab here will bring up the following options
disconnect -- disconnect device and prevent it from automatically activating
list -- get detailed information about devices
status -- print status of devices
wifi -- list available WiFi access points
similarly
nmcli con hit tab will bring up the following
delete -- delete a connection
down -- deactivate a connection
list down -- list configured connections
status -- print status of active connections
up -- activate a connection
nmcli nm
enable -- get status or enable/disable networking
sleep -- get sleep status or put to sleep/awake NetworkManager
status -- show overall status of NetworkManager
