Trunking

Port trunking is the combination of several ports or network cables to expand the
connection speed beyond the limits of any one single port or network cable. The
Managed Switch supports two types of port trunk technology:
• Static Trunk
• LACP
The Link Aggregation Control Protocol (LACP) provides a standardized means for
exchanging information between Partner Systems on a link to allow their Link
Aggregation Control instances to reach agreement on the identity of the Link
Aggregation Group to which the link belongs, move the link to that Link Aggregation
Group, and enable its transmission and reception functions in an orderly manner. 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 refers to IEEE 802.3ad.
