4.10.2 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 make the settings effective. Click Reload to refresh the
settings to current value.
To attach a filter set to ports:
Filter ID/Name: Select a filter name or ID.
Attach to all ports: The filter set applies to all the ports of the system
Attach to certain ports: 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.
Note
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.
