Menu 21.1.1 - Generic Filter Rule
Filter #: 1,1
Filter Type= Generic Filter Rule
Active= Yes
Offset= 6
Length= 6
Mask= ffffffffffff
Value= 0080c84cea63
More= No Log= None
Action Matched= Drop
Action Not Matched= Forward
Key Settings:
• Generic Filter Ruls
Set the 'Filter Type' to 'Generic Filter Rule'
• Active
Turn 'Active' to 'Yes'
• Offset (in bytes)
Set to '6' since the source MAC address starts at 7th octets we need to skip the first octets of the
destination MAC address.
• Length (in bytes)
Set to '6' since MAC address has 6 octets.
• Mask (in hexadecimal)
Specify the value that the Prestige will logically qualify (logical AND) the data in the packet.
Since the Length is set to 6 octets the Mask for it should be 12 hexadecimal numbers. In this case,
we intent to set to 'ffffffffffff' to mask the incoming source MAC address, [00 80 c8 4c ea 63].
• Value (in hexadecimal)
Specify the MAC address [00 80 c8 4c ea 63] that the Prestige should use to compare with the
masked packet. If the result from the masked packet matches the 'Value', then the packet is
considered matched.
