5.3 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, GVRP, VLAN, port attributes, MAC Address Learning
mode and other associated settings. The further explains are as following:
 If the ports, which are enabled for the GVRP, 802.1Q VLAN, Voice VLAN, STP, QoS, Port
Isolation, DHCP Snooping and Port Configuration (Speed, Flow Control), are in a LAG,
their configurations should be the same.
 The ports, which are enabled for the Port Security, Port Mirror, MAC Address Filtering,
Static MAC Address Binding, 802.1X Authentication, IP Source Guard, and half-duplex
cannot be added to the LAG.
 It’s not suggested to add the ports with ARP Inspection and DoS Defend enabled 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.
