Link Aggregation Overview
Link Aggregation is also called Trunk. It refers to bundling of mul-
tiple physical ports into a logical port to implement load balance of
in/out flow in each member port. Switch determines from which
member port to transmit message to the peer end switch accord-
ing to port load sharing policy that the users configured. When
the switch detects that one member port link is broken, it does
not transmit messages in this port until this port link becomes
normal. Link aggregation is a very important technology in adding
link bandwidth, implementing link transmission flexibility and re-
dundancy.

Static Trunk adds multiple physical ports to trunk group; to
form a logical port. This mode goes against observing status
of link aggregation port.
Link Aggregation Control Protocol (LACP) complies with IEEE
802.3ad. LACP aggregates multiple physical ports to trunk
group dynamically through protocol to form a logical port.
LACP generates aggregation automatically to obtain the max-
imum bandwidth.
Thirty-two trunk groups totally can be configured, each trunk
group contains up to eight member ports.
Support cross-interface-board aggregation, the member ports
can be located at any interface board, but the selected port
must work in full-duplex mode and the working rate must be
consistent.
