9.4Applying a Filter and Factory Defaults
This section shows you where to apply the filter(s) after you design it (them). Two sets of factory default filter rules have been configured in Menu 21 to prevent NetBIOS traffic from triggering calls (see Figure 8- 7 Menu 21 - Filter Set Configuration).
9.4.1Ethernet 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 below) 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.
