MAC Address Table—Multicast Filtering
Multicasts are similar to broadcasts, they are sent to all end stations on a LAN or VLAN. Multicast filtering
is the system by which end stations only receive multicast traffic if they register to join specific multicast
groups. With multicast filtering, network devices only forward multicast traffic to the ports that are
connected to registered end stations.
• IP Address: Assign a multicast group IP address in the range of 224.0.0.0 ~ 239.255.255.255.
• Member Ports: Tick the check box beside the port number to include them as the member ports in the
specific multicast group IP address.
• Click Clear M AC Table to clear the current port static MAC address information on screen.
