Link Aggregation
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 (RJ-45, 100 Mbps fiber).

The ports that can be assigned to the same link aggregation have certain other restrictions (see below).

Ports can only be assigned to one link aggregation.

The ports at both ends of a connection must be configured as link aggregation ports.

None of the ports in a link aggregation can be configured as a mirror source port or a mirror target port.

All of the ports in a link aggregation have to be treated as a whole when moved from/to, added or deleted from a VLAN.

The Spanning Tree Protocol will treat all the ports in a link aggregation as a whole.

Enable the link aggregation prior to connecting any cable between the switches to avoid creating a data loop.

Disconnect all link aggregation port cables or disable the link aggregation ports before removing a port link aggregation to
avoid creating a data loop.
