Filter Configuration
34.4.2 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
