208 CyberSWITCH
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
Protocol Definitions
.)

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. Up to 63 MAC addresses can be configured.
The mode of hardware filtering be in manual to configure this element.

A decimal number between 1 and 63 that indicates the maximum number of MAC addresses to be
learned by the CyberSWITCH. The mode of hardware filtering must be in auto to configure this
element.

This timer represents the amount of time the CyberSWITCH will remain in the learning phase.
Once either the time limit or the number of addresses limit is reached, the hardware filtering feature
will be enabled and proceed to the forwarding phase.

This timer represents the amount of time the CyberSWITCH will wait before going back to the
learning phase again. After this time-out, the bridge delete the previously learned addresses and
relearn available MAC addresses.
