Physical port setting guidelines
It is recommended that you use the default settings listed in Port class default settings on page 67 for
most Port class areas. Consider the Port class to be a superset containing the E_Port, FOP_Port, and
FCU_Port subclasses. If you make a change to a default setting for an area in the Port class, it applies
to all of the subclasses. This is convenient if you have determined that changes you plan to make to the
default settings for the subclasses are the same for certain areas. In this case, you only need to make
the changes to the Port class. Note, however, that if you make a change to one of the subclasses, that
change overrides the Port class setting.
