/RATING=DYNAMIC
       /RATING=STATIC=value

    Clients use the service rating to select a service in the case of
    multiple matching services. The service with the highest service
    rating is selected.

    The system adjusts the dynamic service rating based on load. You
    can also set a static rating between 0 and 65535. The system does
    not adjust static ratings.

    One use of static ratings is to migrate clients from one copy
    of a service to another. If you set a static rating of 0 on
    services you want to migrate clients away from, no new clients
    will connect to a 0-rated service; instead, they will connect to
    higher-rated services. When all current clients have disconnected
    from a service, you can safely delete it.
