Note
4.7.2 Filter attach
A filter set is idle if you did not attach it to any ingress port. Use the Filter Attach
page to attach a filter set to ingress ports.
Click
OK to save the configuration. To make the configuration effective, go to
the “Save Configuration” page, then click Save, or click on Reload to refresh the
page.
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 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, it will filter the packets
according to the ingress 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 3. A packet with destination MAC 00:10:20:30:40:50
from port 3 is not permitted.
