Note: 
The switch cannot be managed through the disabled port. Please enable the port which is used to 
manage the switch. 
4.4.2 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 and view the current IGMP Group 
information.

Figure 4-5 IGMP Snooping 
The following entries are displayed on this screen: 
 
IGMP Snooping 
IGMP Snooping: 
Enable or disable IGMP snooping function globally on the switch. 
IP Address: 
Displays the multicast IP address. 
VLAN ID: 
Displays the VLAN ID of the multicast group. If the packet does 
not carry VLAN ID, then here displays the PVID of the port. All port 
members of a multicast group should be divided to the same 
VLAN, and have the same PVID. 
Ports: 
Displays the forwarding port list of the multicast group. 
4.4.3 Port Trunk 
Port trunk is used to combine a number of ports together to make a single high-bandwidth data 
path, which can highly extend the bandwidth. The bandwidth of the trunk is the sum of bandwidth 
of its member ports.   
There are some rules on using trunk: 
 
For the member ports in a trunk group, their configuration of Port setting (Speed and Duplex
Flow Control), QoS must be the same.
