Calculating the Range Covered by a Rule
Adding a mask to an explicit number of any field (COS, VID, TOS, etc.) selection, you can
create a rule which covers a RANGE of values.
This section describes how to calculate the range covered by a rule.
NOTE: You may calculate the range using the Range Calculator Dialog (on page 10-23).
Note that:
 Mask bit, when set to 0 – allows both 0 and 1 bits in result,
 Mask bit, when set to 1 – requires result bit to be matched with a field value bit.
COS
Note that COS bit is provided in Decimal format and Mask is in Binary format.
