1. 网络拓扑

2. SW1配置：
[SW1]vlan batch 10 20
[SW1]interface GigabitEthernet 0/0/1
[SW1-GigabitEthernet0/0/1]port link-type access
[SW1-GigabitEthernet0/0/1]port default vlan 10

[SW1]interface GigabitEthernet 0/0/2
[SW1-GigabitEthernet0/0/2]port link-type access
[SW1-GigabitEthernet0/0/2]port default vlan 20

创建一个聚合链路接口：
[SW1]lacp priority 1
[SW1]interface Eth-Trunk 1
[SW1-Eth-Trunk1]mode lacp-static
[SW1-Eth-Trunk1]max active-linknumber 2
[SW1-Eth-Trunk1]port link-type trunk
[SW1-Eth-Trunk1]port trunk allow-pass vlan 10 20

将端口加入聚合：
[SW1]interface GigabitEthernet 0/0/22
[SW1-GigabitEthernet0/0/22]eth-trunk 1
[SW1]interface GigabitEthernet 0/0/23
[SW1-GigabitEthernet0/0/23]eth-trunk 1
[SW1]interface GigabitEthernet 0/0/24
[SW1-GigabitEthernet0/0/24]eth-trunk 1

3. SW3配置：
以下不用配置：（其余与SW1配置相同）
[SW1]lacp priority 1
[SW1-Eth-Trunk1]max active-linknumber 2
