When using manual link aggregation mode, which of the following description regarding adding member interfaces is wrong?
A . Eth-Trunk interfaces cannot be nested, that is, member interfaces cannot be Eth-Trunk.
B . An Ethernet interface can only be added to any th-Trunk interface. If you need to add another Eth-Trunk interface, you must first exit the original Eth-Trunk interface.
C . If the local device uses Eth-Trunk, the peer interface directly connected to the member interface must also be bundled as an Eth-Trunk interface so that both ends can communicate normally.
D . Eth-Trunk has two working modes: Layer 2 working mode and Layer 3 working mode. Two working modes are automatically recognized, no need to switch manually.
Answer: D
