Why does traffic forwarding fail when an S series switch is connected to another device through Eth-Trunk

After Eth-Trunk link aggregation is configured for an S series switch (except the S1700), the Eth-Trunk works in manual load balancing mode by default. If Eth-Trunk link aggregation is also configured for the peer device, the Eth-Trunk works in LACP mode by default. The two ends of the Eth-Trunk work in different default modes, resulting in forward traffic failure. To ensure normal traffic forwarding, you must configure the same working mode for the two ends.
