Static Filtering
Multicasts are similar to broadcasts in that they are sent to all end stations on a LAN or VLAN. With multicast
filtering, end stations can receive multicast traffic if the connected ports are included in the specified multicast
groups, and network devices only forward multicast traffic to the ports that are connected to the registered end
stations.
To configure filtering, choose Configure-->Multicast Support-->Static Filtering.
