Multicast

Multicast forwarding allows a single packet to be forwarded to multiple
destinations. The 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.

Multicast Filtering

The Multicast Filtering page allows for the definition of action settings
when an unknown multicast request is received. The options include:
Drop, Flood, or Router Port.

IGMP Snooping

IGMP Snooping is defined as the process of listening to Internet Group
Management Protocol (IGMP) network traffic. IGMP Snooping allows a
network switch to listen in on the IGMP conversation between hosts and
routers and maintain a map of which links need which IP multicast
streams. Multicasts can be filtered from the links which do not need them
in turn controlling which ports receive specific multicast traffic.
