Multicast Forwarding Support
Multicast forwarding allows a single packet to be forwarded to multiple destinations. L2 Multicast
service is based on 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.
The switch module supports:
•
Forwarding L2 Multicast Packets — Enabled by default, and not configurable.
NOTE:
•
Filtering L2 Multicast Packets — Enables forwarding of 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, treating the
packet as a Multicast transmission. While this is functional, in the sense that all relevant
ports/nodes receive a copy of the frame, it is potentially wasteful as ports/nodes may receive
irrelevant frames only needed by a subset of the ports of that VLAN. Multicast forwarding filters
enable forwarding of Layer 2 packets to port subsets, defined in the Multicast filter database.
