The icfVgGroupPortCapacity is the number of ports
that can be contained within the group. Valid range
is 1-1024. Within each group, the ports are uniquely
numbered in the range from 1 to
icfVgGroupPortCapacity. Some ports may not be
present in a given group instance, in which case the
actual number of ports present is less than
icfVgGroupPortCapacity. The number of ports present
is never greater than icfVgGroupPortCapacity.
