Configuring a Dynamic LACP Aggregation Group
A dynamic LACP aggregation group is automatically created by the system based on LACP-enabled
ports. The adding and removing of ports to/from a dynamic aggregation group are automatically
accomplished by LACP.
You need to enable LACP on the ports which you want to participate in dynamic aggregation of the
system, because, only when LACP is enabled on those ports at both ends, can the two parties reach
agreement in adding/removing ports to/from dynamic aggregation groups.
You cannot enable LACP on a port which is already in a manual aggregation group.
