phenomenon:
After aggregation, two links form one logical link and thus the
bandwidth is doubled. Besides, the load is shared based on the source or
destination MAC address. When one link in the aggregation group is
disconnected, the packet is sent through another link, and thus the
communication is not interrupted.
