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
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.
