- 创建Eth-Trunk接口
[Stack]int Eth-Trunk 1
[Stack-Eth-Trunk1]port link-type trunk
[Stack-Eth-Trunk1]port trunk allow-pass vlan all
[LSW3]interface Eth-Trunk 1
[LSW3-Eth-Trunk1]port link-type trunk
[LSW3-Eth-Trunk1]port trunk allow-pass vlan all - 加入Eth-Trunk的成员接口
[Stack-GigabitEthernet0/0/1]eth-trunk 1
[Stack-GigabitEthernet0/0/3]eth-trunk 1
[LSW3]interface Eth-Trunk 1
[LSW3-Eth-Trunk1]trunkport GigabitEthernet 0/0/1 to 0/0/2 - 使能Eth-Trunk接口流量本地优先转发功能
[Stack-Eth-Trunk1]local-preference enable - 配置各接口加入相应VLAN，实现二层互通
