Link Aggregation in Manual Mode
Link aggregation can work in manual mode or static LACP mode depending on whether LACP is used.
In manual mode, you must manually create an Eth-Trunk and add member interfaces to the Eth-Trunk. Manual mode can be used when two directly connected devices require a high link bandwidth between them, but the remote device does not support the LACP protocol.
In Figure 3-2, an Eth-Trunk is created between DeviceA and DeviceB. In manual mode, three active links participate in data forwarding and load balance traffic. When one link becomes faulty, the remaining two links can still load balance traffic assuming the remaining pipes have sufficient bandwidth.
