The nmcli connection command can be used to list your network interfaces. Something like this should be returned. Often, this will produce the same exact output as the nmcli connection show command.

~]# nmcli connection
NAME  UUID                                  TYPE      DEVICE 
eth0  5fb06bd0-0bb0-7ffb-45f1-d6edd65f3e03  ethernet  eth0

The nmcli connection show command will display basic information about your network interface connection.

~]# nmcli connection show
NAME  UUID                                  TYPE      DEVICE 
eth0  5fb06bd0-0bb0-7ffb-45f1-d6edd65f3e03  ethernet  eth0

The --active flag can be used to only display active connections.

~]# nmcli connection show --active
NAME  UUID                                  TYPE      DEVICE 
eth0  5fb06bd0-0bb0-7ffb-45f1-d6edd65f3e03  ethernet  eth0

Specifying a connection will show the settings for the connection.

~]# nmcli connection show ens192
connection.id:                          ens192
connection.uuid:                        08e06b69-1e5c-39f0-b9db-9f4c3c9c7903
