LAG Config 
Group Number: 
Select a Group Number for the LAG.   
Description: 
Displays the description of LAG. 
 
LAG Table 
Member Port:
 
Select the port as the LAG member. Clearing all the ports of
the LAG will delete this LAG. 
 Tips: 
1.  The LAG can be deleted by clearing its all member ports. 
2.  A port can only be added to a LAG. If a port is the member of a LAG or is dynamically 
aggregated as the LACP member, the port number will be displayed in gray and can not be 
selected. 
5.2.3 LACP Config 
LACP (Link Aggregation Control Protocol) is defined in IEEE802.3ad and enables the dynamic link 
aggregation and disaggregation by exchanging LACP packets with its partner. The switch can 
dynamically group similarly configured ports into a single logical link, which will highly extend the 
bandwidth and flexibly balance the load. 
With the LACP feature enabled, the port will notify its partner of the system priority, system MAC, 
port priority, port number and operation key (operation key is determined by the physical 
properties of the port, upper layer protocol and admin key). The device with higher priority will lead 
the aggregation and disaggregation. System priority and system MAC decide the priority of the 
device. The smaller the system priority, the higher the priority of the device is. With the same 
system priority, the device owning the smaller system MAC has the higher priority. The device with 
the higher priority will choose the ports to be aggregated based on the port priority, port number 
and operation key. Only the ports with the same operation key can be selected into the same 
aggregation group. In an aggregation group, the port with smaller port priority will be considered 
as the preferred one. If the two port priorities are equal, the port with smaller port number is 
preferred. After an aggregation group is established, the selected ports can be aggregated 
together as one port to transmit packets.   
On this page, you can configure the LACP feature of the switch.
