Tp-Link TL-SG1024DE [25/48] Igmp snooping

Status: Allows you to enable or disable the port. “Enable" indicates that

the port is operational an

d "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.

Speed/Duplex: 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.

Flow Control: Allows you to On/Off the Flow Control feature. When “On”

selected

, the switch can synchronize the speed with its peer to

avoid the packet loss caused by congestion.

Note:

The switch cannot be managed through the disabled port. Please enable the port which is used to

manage the switch.

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.
