The Link Aggregation Control Protocol (LACP) provides a standardized means for exchanging information
between Partner Systems that require high speed redundant links. Link aggregation lets you group up to eight
consecutive ports into a single dedicated connection. This feature can expand bandwidth to a device on the
network. LACP operation requires full-duplex mode, more detail information refer to the IEEE 802.3ad standard.
Port link aggregations can be used to increase the bandwidth of a network connection or to ensure fault
recovery. Link aggregation lets you group up to 4 consecutive ports into a single dedicated connection between
any two the Switch or other Layer 2 switches. However, before making any physical connections between
devices, use the Link aggregation Configuration menu to specify the link aggregation on the devices at both ends.
When using a port link aggregation, note that:
• The ports used in a link aggregation must all be of the same media type (RJ45, 100 Mbps fiber).
• The ports that can be assigned to the same link aggregation have certain other restrictions (see below).
