这里使用交换机万兆口3口与4口做的链路聚合，为trunk模式

创建ETH-trunk1

[HUAWEI]interface Eth-Trunk 1

链路聚合模式为trunk模式，并且放通全部vlan

[HUAWEI-Eth-Trunk1]port link-type trunk
[HUAWEI-Eth-Trunk1]port trunk allow-pass vlan all 

将XG0/0/3与XG0/0/4加入到ETH-trunk1中

[HUAWEI]interface XGigabitEthernet 0/0/3
[HUAWEI-XGigabitEthernet0/0/3]eth-trunk 1

[HUAWEI-Eth-Trunk1]display eth-trunk 1
Eth-Trunk1's state information is:
