CTION
For each filter category, there are three filtering actions that the system can perform on a packet:
discard, forward, or connect the packet.
MAC-A
DDRESS
An assigned Media Access Control address as defined by IEEE 802.3 specifications. MAC-
addresses are specified as 12 character hexadecimal numbers.
M
ULTICAST
A
DDRESS
A Media Access Control address with the group bit set to 1.
D
ISTRIBUTION
L
IST
A distribution list is defined as the WAN and/or LAN ports to which the filter action will be
applied. The distribution list is selected from a displayed list of possible choices (LAN, WAN,
Device Table, or all destinations).
M
ASK
Hexadecimal number up to 80 characters in length that specifies which bits in the data packets are
significant. There must be an even number of hexadecimal digits in the number. A scale will be
displayed to help you enter the Mask accurately.
D
ATA
V
ALUE
Hexadecimal number up to 80 characters in length that specifies the value used to determine if the
packet matches the filter. The value field must be a subset of the mask field. That is, the value field
logically “anded” with the mask field must be equal to the value field. The value and mask fields
must have equal lengths. There must be an even number of hexadecimal digits in the number.
P
ACKET
O
FFSET
A decimal number between 1 and 100 that indicates the starting offset in a data packet where a
packet filter will begin its data comparison.
P
ROTOCOL
-I
D
The symbolic name for the Ethernet protocol to be filtered. The protocol-Id is selected from a
displayed list of previously defined protocols. (Refer to the section titled
.)
