5-4-5. Trunking
Trunking 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 it's backup.
