Huawei's two switches, SWA and SWB, are connected through seven Ethernet ports and are configured with static link aggregation. The corresponding ports on the switch SW are Ethernet 1/0/2, Ethernet 1/0/3, Ethernet 1/0/4, and Ethernet 1/0/5, Ethernet 1/0/6, and Ethernet 1/0/7. The configuration mode is configured in the order of the ports. If the switch SWA and SWB support only 6 ports in each aggregation group.

• A.In the case that the configurations of the ports are the same, the SWA randomly selects one of the seven ports as the aggregation group Unselected port.
• B.Ethernet1/0/7 Unselected port with consistent port configuration
• C.Ethernet1/0/6 Unselected port with consistent port configuration
• D.Ethernet1/0/1 Unselected port when the configurations of the ports are the same
