To attach a filter set to ports:
• Attach to all ports: the filter set applies to all the ports of the system.
• Attach to certain ports: you can specify the ingress ports and egress
port to be applied.
• Detach from all ports: remove all the filters from the attached ports.
You may not detach certain ports after issuing an "Attach All"
command. If you wish to detach ports, use the "Detach All"
command.
Once the filter set is attached to the ingress ports and egress ports, it will
filter the packets according to the ingress port, egress port, and the packet
fields in the rules. For example, a set with a single rule to filter out
destination MAC address 00:10:20:30:40:50 is attached to ingress port 1
and egress port 2. A packet with destination MAC 00:10:20:30:40:50 from
port 1 is not switched to port 2, but it is possible to go to other ports except
port 2 in flooding situation.
