7.9 IGMP (IP Multicast)
Multicasting is used to support real-time applications such as video conferencing or streaming audio. IGMP (
Internet Group Management Protocol ) allow you to query for any attached hosts who want to receive a specific
multicast service. The switch looks up the IP Multicast Group used for this service and adds any port which
received a similar request to that group. It then propagates the service request on to any neighboring multicast
switch to ensure that it will continue to receive the multicast service.
If you want your switch to support multimedia and IP multicast, enable this option (default is enabled). When this
option is enabled, this switch only directs the multicast data packets to the ports where needed, saving bandwidth. If
Forward with high priority is enabled, then the IP multicast traffic will have a higher priority than other traffic.
