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

After an Eth-Trunk is configured on the switch, the manual load balancing mode is adopted on the Eth-Trunk by default. If the device connected to the switch uses the static LACP mode after link aggregation is configured, the two devices use different working modes at two ends of the Eth-Trunk. As a result, traffic cannot be transmitted on the Eth-Trunk. To ensure traffic transmission on the Eth-Trunk, you need to set the same working mode on the two devices.
