Chapter 29 Filter Configuration

For generic rules, the ZyAIR treats a packet as a byte stream as opposed to an IP or IPX
packet. You specify the portion of the packet to check with the
Offset
(from 0) and the
Length
fields, both in bytes. The ZyAIR 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
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
Generic Filter Rule
in the
Filter Type
field in menu
21.1.4.1 and press
[ENTER]
to open Generic Filter Rule, as shown below.
