LACP is a dynamic protocol which helps to automate
thecongurationandmaintenanceofLAG’s.Themain
purposeofLACPistoautomaticallycongureindividual
links to an aggregate bundle, while adding new links and
helping to recover from link failures if the need arises.
LACP can monitor to verify if all the links are connected
to the authorized group. LACP is a standard in comput-
er networking, hence LACP should be enabled on the
Switch’s trunk ports initially in order for both the partic-
ipating Switches/devices that support the standard, to
use it.
