Creating a new connection on interface not used before using nmcli

Trying to setup a new connection using nmcli. The system is debian wheezy, the platform ci20.

I am missing an ID or UUID parameter in order to perform nmcli con up [id | uuid ]

It complains about this argument missing, but since no connection was made through this interface before I don't seem to be able to get it anywhere.

When I do nmcli con it spits out two previous connections on a different interface.

Maybe I'm missing something obvious, not sure, kinda stuck. Maybe I should be doing something else entirely in order to achieve what I want to achieve, not sure.

No gui present, would prefer to set it from the command line interface if it's possible.

Thanks in advance.
