5.2 LAG

LAG (Link Aggregation Group) is to combine a number of ports together to make a single

high-bandwidth data path, so as to implement the traffic load sharing among the member ports in

the group and to enhance the connection reliability.

For the member ports in an aggregation group, their basic configuration must be the same. The

basic configuration includes STP, QoS, VLAN, port attributes, MAC Address Learning mode

and other associated settings. The further explains are following:

 If the ports, which are enabled for the 802.1Q VLAN, STP, QoS and Port Configuration

(Speed and Duplex, Flow Control), are in a LAG, their configurations should be the same.

 The ports, which are enabled for the Port Security, Port Mirror and MAC Address Filtering,

can not be added to the LAG.

If the LAG is needed, you are suggested to configure the LAG function here before configuring the

other functions for the member ports.

Tips:

1. Calculate the bandwidth for a LAG: If a LAG consists of the four ports in the speed of

1000Mbps Full Duplex, the whole bandwidth of the LAG is up to 8000Mbps (2000Mbps * 4)

because the bandwidth of each member port is 2000Mbps counting the up-linked speed of

1000Mbps and the down-linked speed of 1000Mbps.

2. The traffic load of the LAG will be balanced among the ports according to the Aggregate

Arithmetic. If the connections of one or several ports are broken, the traffic of these ports will

be transmitted on the normal ports, so as to guarantee the connection reliability.

The LAG function is implemented on the LAG Table and Static LAG configuration pages.
