If a port is the member of a LAG, the port number will be displayed in gray and cannot 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.
Select the port as the LAG member. Clearing all the ports of
the LAG will delete this LAG.
