The Multicast Port Filtering Mode window is divided into two sections. The top section allows the user to change the multicast
port filtering mode of specific ports. The bottom section of the window displays all the ports on the Switch and the Multicast Port
Filtering Mode they have been configured with.
The following parameters can be set in the Multicast Port Filtering Mode Setup section of the window:
Parameter Description
From/To
Select the ports that require their Multicast Port Filtering Mode to be changed from the drop-down
menus.
Mode
Choose the following Multicast Port Filtering Mode from the drop-down menu:
Forward All Groups- In this mode all frames destined for group MAC addresses are forwarded
according to the VLAN rule.
Forward Unregistered Groups- In this mode if the Group MAC Address Registration entries exist
in the Multicast Table, frames destined for the corresponding Group MAC addresses are
forwarded only to ports identified in the member port set. On the other hand, if the Group MAC
address does not exist in the Multicast Table the frames are forwarded according to the VLAN
rule.
Filter Unregistered Groups- In this mode frames destined for group MAC addresses are only
forwarded only if such forwarding is explicitly permitted by a Group Address entry in the
Multicast Table. In other words, if the Group MAC address does not exist in
the Multicast table, the packets are dropped.
