+custom_ports
+    A mapping of service names to port numbers that will override the
+    default ports used for those services. The service names are:
+    ``smb``, ``smbmetrics``, and ``ctdb``. If a service name is not
+    present in the mapping the default port will be used.

+    ports used by smb for client access and the metrics exporter, but
+    not change the port used by the CTDB clustering daemon.
