Right Mask The value field is 64-bit long in a Boolean comparison.
If the value you specified is less than 64 bits, select a mask between 0 and
63 to define how many bit(s) from the right will turn to zero and not be
used for comparison when the specified value is right-aligned. This is useful
when you want to check only few bits in a pre-defined field, such as the 3-
bit CoS value (by setting the left mask to 48 and the right mask to 13) or
12-bit VLAN ID (by setting the left mask to 52) in a 32-bit VLAN tag.
For example, if the value you specified is a network address with a 24-bit
subnet mask, set the left mask to 32 and the right mask to 8.
Operator Select the operator that applies to the incoming packets.
Select == (equal to) and the matched packet must contain the field exactly
the same as what you specified in the Field and Value fields.
Select != (not equal to) and the matched packets must not contain the field
exactly the same as what you specified in the Field and Value fields.
Select <= and the matched packet must contain the field which is less than
or equal to what you specified in the Value field.
Select >= and the matched packet must contain the field which is greater
than or equal to what you specified in the Value field.
Select exists and the matched packet must include the field you specified
in the Field field.
Select !exists and the matched packet must not include the field you
specified in the Field field.
Select Always match and the packet always matches the profile regardless
of what you specified in the Field and Value fields.
