The fewest number of interfaces that can be SANTap enabled is four.
The first interfaces in a group must be 1, 5, 9, 13, 17, 21, 25, or 29. (You can specify fc5 through
fc8, but not fc7 through fc10.)
The groups of four interfaces do not need to be consecutive. For example, you can specify fc1
through fc8 and fc17 through fc20.
