Value
va
(Blank)
A value to match in hexadecimal notation.
When matching parts of a packet, you must enter exactly
what you are matching against. Used in conjunction with
the Mask parameter, the Value parameter allows you to
match against a specific value at a specific mask
location.
In the following example, we have entered a mask of 80,
specifying that we want to match a value in position 8 of
the first half of a byte:
The value that we want to match here is 0. The value
entered in the Value parameter then is 00. This specifies
that we want to match a zero against the first position of
the byte as specified in the Mask parameter.
In the next example, a mask value of 96 has been
entered. The mask specifies that we are checking
positions 8 and 1 in the first half of the byte and
positions 4 and 2 in the second half:
Using this mask, we want to match a 1 in position 8 and
a 0 in position 1 of the first half of the byte and a 0
against position 4 and 2 in the second half. The value
entered here (in hexadecimal) is 80.
