And now we should connect the two switches’ corresponding ports with three cables. We’ve finished the whole configuration process. And modify status as Enable, Group ID as 2, Port Priority as 32768, Mode as Passive. On the main Web page, go to L2 FEATURES-> Switching-> LAG-> LACP Config. The configuration process is basically the same as above. It is suggested that set one side as Active mode and the other side as Passive mode. In Active mode, the port can send LACP packets actively while in Passive mode, the port can only send LACP packets after it has received a LACP packet. There are two modes of ports: Active and Passive.

If the System Priority value is the same, the device with smaller MAC address owns higher priority.Ģ. When exchanging information between systems, the system with higher priority determines which link aggregation a port belongs to, and the system with lower priority adds the proper ports to the link aggregation according to the selection of its partner. A lower system priority value indicates a higher system priority. And click Apply to take settings into effect.ġ. Then Choose Mode as Active and Status as Enable. The ports with the same Admin Key will be aggregated to the same group. Check port 10, 11, 12, designate an Admin Key 2 for these ports. Go to Switching-LAG-LACP Config as screenshots below. We want to aggregate port 10, 11, 12 of T3700G-28TQ and port 22, 23, 24 of T2600G-28TS via LACP protocol.īefore everything, at the first place we cannot connect the two switches through three cables at the same time because it will make broadcast storm if there is no advanced configuration like LAG.

Here we take an example to clarify how to configure LACP feature between two TP-Link switches.Īs shown in the picture below, here are T3700G-28TQ v1 and T2600G-28TS v3. LACP, defined in IEEE802.3ad, is used to combine multiple physical links dynamically as a logical link, and thus this logical link will have higher bandwidth and higher reliability.
LAG is short for link aggregation group, including static LAG and LACP(Link Aggregation Control Protocol) two achievement mechanisms.
