Modifies the proportion of bits assigned to the VPI and VCI
for a given VCC or VPI/VCI set. The combined total of VPI
and VCI bits must equal 12. The four most common VCC
masks are predefined in the system (see
modify portconfig).
When modifying a VPI/VCI set, you must specify the VCC
mask by using the mask index identifier. If you modify a
specific mask index, for example a VPI/VCI set is modified
from 6/6 to 7/5, you will modify occurrences of the 6/6
configuration on all ports, as only four different VCC masks
configurations can exist at any one time.
