6.4 Applying a Filter and Factory Defaults
This section shows you where to apply the filter(s) after you design it (them).
6.4.1 Ethernet Traffic
You seldom need to filter Ethernet traffic; however, the filter sets may be useful to block certain packets,
reduce traffic and prevent security breaches. Go to Menu 3.1 (shown next) and enter the number(s) of the
filter set(s) that you want to apply as appropriate. You can choose up to four filter sets (from twelve) by
entering their numbers separated by commas, e.g., 3, 4, 6, 11. Input filter sets filter incoming traffic to the
Prestige and Output filter sets filter outgoing traffic from the Prestige.

6.4.2 Cable Port Filters
Go to Menu 4.1 (shown next) and enter the number(s) of the filter set(s) as appropriate. You can cascade up
to four filter sets by entering their numbers separated by commas.
