4.4 Multicast

The Internet Group Management Protocol (IGMP) is a protocol used to manage IP multicast
members. It sets up and maintains the member relationship between IP hosts and their directly
connected multicast routers.

4.4.1 IGMP Snooping

Located between hosts and a multicast router, the S3700 supports static multicast forwarding
entries and generates a dynamic Layer 2 multicast forwarding table with multicast groups,
VLANs, and outbound interfaces by listening to IGMP messages.

When the S3700 receives a multicast packet, it forwards the packet only to the members on the
VLAN corresponding to the multicast group. The multicast packet is transmitted in multicast
mode on the VLAN according to the Layer 2 multicast forwarding table. This saves bandwidth
and enhances the security of information transfer.
