LACP (802.3ad) provides the dynamic link aggregation function.
The LACPDU includes the LACP system priority, the system MAC, the port priority, and I.D. The port, included in the LACP LAG, will transmit the LACPDU to its neighbors.
The configuration of the LACP LAG is similar to that of the static LAG.
The min-selected-port label denotes that the LAG is up only when no fewer than the defined number of ports are up. Below, our defined number is 4.
Configuring LACP LAGs
