Port class guidelines and default settings
7
Physical port setting guidelines
It is recommended that you use the default settings listed in Table 16 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.
Port class default settings
Table 16 provides default settings for areas in the Port class.
