IGMP Snooping: Enable or disable IGMP snooping function globally on the switch.

¾ Multicast IP Table

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.

4.3 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:

z For the member ports in a trunk group, their configuration of Port setting (Speed and

Duplex, Flow Control), QoS must be the same.

z For the newly joined member ports in a trunk group, their default setting of Port setting

(Speed and Duplex, Flow Control), QoS will be configured the same as that of the first

member port in the trunk group.

z The trunk member ports cannot be set as mirroring port.

z Before setting the trunk, its member ports should be divided to the same VLAN, and have the

same PVID and drop the untagged packet rule. Change of the trunk setting will not affect the

VLAN setting.

If the port trunk is needed, you are suggested to configure the port trunk function here before

configuring the other functions for the member ports.
