Figure 5-11. Port Priority – Type of Service
IGMP (IP Multicast)
IGMP is used in multicast communication network applications
where one or more servers, for example, video servers, generate
multicast traffic. 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" option is enabled, then the IP multicast traffic will have a
higher priority than other traffic.
