Hi,


These messages are printed by "nm-dispatcher" (in systemd, the service is called 
NetworkManager-dispatcher.service).

The NetwokManager.conf configuration primarily affects what NetworkManager itself (NetworkManager.service) 
prints.

With the additional behavior, that when you enable
  level=DEBUG|TRACE
  domains=DISPATCH (or ALL, or DEFAULT)
then also nm-dispatcher will log additional Debugging logs.


The logs you are seeing are logged by nm-dispatcher with info level.
These cannot be disabled.

Well, actually, nm-dispatcher uses syslog (journald).
The intended way to configure this, is by configuring syslog/journal accordingly.


For example, `man systemd.exec` explains a "LogLevelMax" parameter.
Though, I don't know if that is available on CentOS 7.4 (because it's rather new). But surely, there are ways 
to configure syslog...


best,
Thomas
