The switch supports IP multicasting. You can enable IGMP via the web
management’s configuration screen. In addition, you can view different
multicast groups, VIDs and member ports, and IP multicast addresses that
range from 224.0.0.0 through 239.255.255.255.
The Internet Group Management Protocol (IGMP) is an internal protocol of the
Internet Protocol (IP) suite. IP manages multicast traffic by using switches,
routers, and hosts that support IGMP. Enabling IGMP allows the ports to detect
IGMP queries and report packets and manage IP multicast traffic through the
switch. IGMP has three fundamental types of messages.
