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.
