Permanent NIC Setup from command line???

[Peter Ulrich Kruppa]

Hi,

this is the background to question:

Last week I set up my first Fedora (21) server - everything went well 
until ... now, of course "I didn't do anything" (TM) ... all my network 
configuration was gone.
First Aid was to set my NIC with the ip command - but this won't 
survive a reboot.

Reading the fine manuals led me to NetworkManager and nmcli but
    # systemctl status Networkmanager
    ● Networkmanager.service
    	   Loaded: not-found (Reason: No such file or directory)
            Active: inactive (dead)
doesn't look good.

So now my question: What would be "the" Fedora 21 way to set up a NIC 
permanently from command line?

Thanks and regards

Peter
