Lacp Config - Planet FGSW-2840 User Manual

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.

4.3.2.3 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 Managed 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.
