The AR supports the following link aggregation modes:
Manual load balancing mode: This mode allows you to manually add interfaces to an Eth-Trunk. All the member interfaces are in forwarding state and perform load balancing.
Static LACP mode: This mode allows the AR to select active links by negotiating parameters using LACP. In static LACP mode, you need to manually set up an Eth-Trunk and add interfaces to the Eth-Trunk.
