5-4-5. Trunking

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 allows grouping of 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 IEEE 802.3ad.

If there are two trunk groups A and B, and B group is enabled LACP, then it

will act as a redundant link (Backup group for Trunk group A). If trunk group A

fails, Group B will be its backup.
