Using ATX Port Filtering
4-2
• Port filters use the physical index number of a bridge port to determine
whether traffic is to be screened at the port. These filters are useful for
screeningpacketsfrombeingforwardedontoaport’sattachedsegment.When
youuse Portfilters in combinationwith BridgeAddressTable entries, youcan
create highly specific filtering conditions to allow certain packets to be
forwarded onto a port’s attached segment, or be filtered from it. For example,
you could make a filter that screens packets only if they are forwarded from
Port 3 of the ATX, are AppleTalk protocol packets, and are destined for a
station with an XYZ physical address.
The Port Filtering window (Figure 4-1) allows you to view and configure the
ATX’s Port Filtering capabilities.
To access the Port Filtering window:
1. Click on the PPE’s Module Index (Module 1). The Module menu will appear.
2. Drag down Port Filtering, and release. The Port Filtering window, Figure 4-1,
will appear.
