OK,
I think the cause is that although the connection profile was created correctly in /etc/NetworkManager/system-connections/ on Vivid, the change won't be reflected in the "nmcli con show" command.
Not until it's refreshed with "nmcli con reload"
BTW, it seems that the "nmcli con show" command on Vivid and "nmcli con list" command on Precise are equivalent to "nmcli con" on both distributions.
