Configuring LACP
A dynamic LAG is LACP-enabled, and LACP is run on every candidate port
defined in the LAG.

LACP system priority and LACP port priority are both used to determine which of
the candidate ports become active member ports in a dynamic LAG configured
with more than eight candidate ports.
The selected candidate ports of the LAG are all connected to the same remote
device. Both the local and remote switches have a LACP system priority.
