1、实验需求：
按照图中的IP对PC进行配置，在SW1与SW2上配置链路聚合，确保其中任何一根链路离线，另外一个链路依旧能够提供通信。
2、实验拓扑
3、实验步骤
（1）配置PC地址，此部分省略。
（2）配置SW1与SW2交换机上的链路聚合。
SW1：
[H3C]int Bridge-Aggregation 1
SW2：
[H3C]int Bridge-Aggregation 1
（3）将SW1与SW2交换机上两个接口加入链路聚合。
SW1：
[H3C]int g1/0/1
[H3C-GigabitEthernet1/0/1]port link-aggregation group 1
[H3C]int g1/0/2
[H3C-GigabitEthernet1/0/2]port link-aggregation group 1
SW2：
[H3C]int g1/0/1
[H3C-GigabitEthernet1/0/1]port link-aggregation group 1
[H3C]int g1/0/2
[H3C-GigabitEthernet1/0/2]port link-aggregation group 1
（4）查看链路运行状态
SW1：
[H3C]display link-aggregation verbose
Loadsharing Type: Shar -- Loadsharing, NonS -- Non-Loadsharing
Port: A -- Auto
Port Status: S -- Selected, U -- Unselected, I -- Individual
Flags: A -- LACP_Activity, B -- LACP_Timeout, C -- Aggregation,D -- Synchronization, E -- Collecting, F -- Distributing,G -- Defaulted, H -- ExpiredAggregate Interface: Bridge-Aggregation1
Aggregation Mode: Static
Loadsharing Type: SharPort Status Priority Oper-Key
--------------------------------------------------------------------------------GE1/0/1 S 32768 1GE1/0/2 S 32768 1
（5）配置SW1与SW2上的两个接入为Trunk接口类型，允许所有接口通过。由于链路聚合会自动承接物理接口的属性，所以不需要在物理接口上配置Trunk，直接在链路聚合接口下配置即可。
SW1：
[H3C]int Bridge-Aggregation 1
[H3C-Bridge-Aggregation1]port link-type trunk
Configuring GigabitEthernet1/0/1 done.
Configuring GigabitEthernet1/0/2 done.
[H3C-Bridge-Aggregation1]port trunk permit vlan all
Configuring GigabitEthernet1/0/1 done.
Configuring GigabitEthernet1/0/2 done.
SW2：
[H3C]int Bridge-Aggregation 1
[H3C-Bridge-Aggregation1]port link-type trunk
Configuring GigabitEthernet1/0/1 done.
Configuring GigabitEthernet1/0/2 done.
[H3C-Bridge-Aggregation1]port trunk permit vlan all
Configuring GigabitEthernet1/0/1 done.
Configuring GigabitEthernet1/0/2 done.
（6）测试连通性。
PC3：

（7）断掉一根链路再进行测试。
SW1：
[H3C]int g1/0/1
[H3C-GigabitEthernet1/0/1]shutdown
（8）断掉后测试连通性。
