If not try the online Red Hat Documentation.
-:-"Using the NetworkManager Command Line Tool, nmcli"-:-
https://access.redhat.com/documentat...ool_nmcli.html

If Red Hat is your guest what distribution is your host?

you must have an adapter (device) for the interface. in this case it is eno16777736. so ifname should always be eno16777736 except you have other option in : nmcli dev status like eno2 or etc. you must in this case have only two option 1. eno16777736 and 2. lo. so u can only use one interface at this time. if you have 2 physical ethernet or a ethernet and a wireless interface then youcan add more than one ifname.

in rhel 6 this was not the case. but in 7 it is.
