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. For more detailed
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 8 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).
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.
It allows a maximum of 8 ports to be aggregated at the same time. The Managed Switch supports
Gigabit Ethernet ports (up to 8 groups). If the group is defined as an LACP static link aggregation group,
then any extra ports selected are placed in a standby mode for redundancy if one of the other ports fails.
If the group is defined as a local static link aggregation group, then the number of ports must be the
same as the group member ports.
