By default, two port groups of the XP4 card are created. The member ports are
port 0 to 1 and port 2 to 3 respectively. The system allocates port group numbers
automatically. They are 300 + 2 x slot-no. and 300 + 2 x slot-no. + 1 respectively.
"slot-no" indicates the number of the slot where the XP4 card resides. For
example, when the XP4 card resides in slot 1, the corresponding port group
numbers are 302 and 303. The following section describes the special limits on the
port group configuration of the XP4 card:
