30.4.2 Generic Filter Rule
This section shows you how to configure a generic filter rule. The purpose of generic rules is
to allow you to filter non-IP packets. For IP, it is generally easier to use the IP rules directly.
For generic rules, the Prestige treats a packet as a byte stream as opposed to an IP packet. You
specify the portion of the packet to check with the
Offset
(from 0) and the
Length
fields, both
in bytes. The Prestige applies the Mask (bit-wise ANDing) to the data portion before
comparing the result against the Value to determine a match. The
Mask
and
Value
fields are
specified in hexadecimal numbers. Note that it takes two hexadecimal digits to represent a
byte, so if the length is 4, the value in either field will take 8 digits, for example, FFFFFFFF.
To configure a generic rule select an empty filter set in menu 21, for example 5. Select
Generic Filter Rule
in the
Filter Type
field and press
[ENTER]
to open
Menu 21.1.5.1 –
Generic Filter Rule
, as shown in the following figure.
