Snooping cannot tell the multicast packet from the broadcast packet, so it can only treat
them all as the broadcast packet. Without IGMP Snooping, the multicast packet forwarding
function is plain and nothing is different from broadcast packet.
A switch supported IGMP Snooping with the functions of query, report and leave, a type of
packet exchanged between IP Multicast Router/Switch and IP Multicast Host, can update
the information of the Multicast table when a member (port) joins or leaves an IP Multicast
Destination Address. With this function, once a switch receives an IP multicast packet, it will
forward the packet to the members who joined in a specified IP multicast group before. The
packets will be discarded by the IGMP Snooping if the user transmits multicast packets to
the multicast group that had not been built up in advance. IGMP mode enables the switch
to issue IGMP function that you enable IGMP proxy or snooping on the switch, which
connects to a router closer to the root of the tree. This interface is the upstream interface.
The router on the upstream interface should be running IGMP.
