The L2 Multicast service is based on an L2 switch receiving a single packet addressed to a specific Multicast address. Multicast forwarding creates copies of the packet, and transmits the packets to the relevant ports. This device supports: • Forwarding L2 Multicast Packets - Forwards Layer 2 Multicast packets. Layer 2 Multicast filtering is enabled by default and is not user-configurable. NOTE: The system supports Multicast filtering for 256 Multicast groups. • Filtering L2 Multicast Packets - Forwards Layer 2 packets to interfaces. If Multicast filtering is disabled, Multicast packets are flooded to all relevant ports. To open the Multicast Support page, click Switch→Multicast Support in the tree view. Defining Multicast Global Parameters Layer 2 switching forwards Multicast packets to all relevant VLAN ports by default, managing the packet as a Multicast transmission. While Multicast traffic forwarding is effective, it is not optimal as irrelevant ports also receive the Multicast packets. The excess packets cause increased network traffic. Multicast forwarding filters enable forwarding of Layer 2 packets to port subsets. Configuring Switch Information 317
