Port-to-Port Filtering
A
port-to-port
filter set is a group of ports that are allowed to
communicate through the bridge. There is a port-to-port filter set
for each bridge port.
Figure 1-24
and Figure 1-25 illustrate a port-to-port filter
example. Figure 1-24
shows four network segments connected by
a bridge. The ports' filter sets have been set up, allowing
communication between ports 1 and 2, ports 1 and E, and ports
2 and 3.
Figure 1-24 Port-to-Port Filtering Example
Figure 1-25 shows the port communications that are allowed.
