5.2 IGMP Snooping

Internet Group Management Protocol (IGMP) snooping is a multicast control mechanism, which
can be used on the switch for dynamic registration of the multicast group.
IGMP Snooping allows the switch to recognize the IGMP messages transmitted between network
stations or devices and an IGMP host. When receiving IGMP report message from the IGMP host,
the switch will add the port to the multicast address table; when listening to IGMP leave message
from the IGMP host, the switch will remove the port from the multicast address table. By managing
and controlling the multicast address table, the broadcasting of multicast traffic can be effectively
prevented in the network.
On this page you can enable IGMP Snooping feature, Report Message Suppression feature and
view the current IGMP Group information.
Choose the menu Switching→IGMP Snooping to load the following page.
Allows you to enable or disable the port. "Enable" indicates that
the port is operational and "Disable" indicates the port is
non-operational. If a port is unused for a long time, its status can
be set to "Disable" to cut down the energy cost.
Select the Speed and Duplex mode for the port. The device
connected to the switch should be in the same Speed and Duplex
mode with the switch. Available field values are "Auto", "10M HD",
"10M FD", "100M HD", "100M FD" and "1000M FD". "HD" stands
for Half-Duplex and "FD" stands for Full-Duplex. "Auto" means
auto negotiation.
Allows you to On/Off the Flow Control feature. When "On" is
selected, the switch can synchronize the speed with its peer to
avoid the packet loss caused by congestion.
