配置步骤

交换机A的配置

采用动态聚合模式：创建二层聚合接口，并配置动态聚合模式

[设备A]interface bridge-aggregation 1
[设备A-Bridge-Aggregation1] link-aggregation mode dynamic
[设备A-Bridge-Aggregation1] quit
[设备A]interface gigabitethernet 1/0/1
[设备A-GigabitEthernet1/0/1] port link-aggregation group 1
[设备A-GigabitEthernet1/0/1] quit
[设备A]interface gigabitethernet 1/0/2
[设备A-GigabitEthernet1/0/2] port link-aggregation group 1
[设备A-GigabitEthernet1/0/2] quit
[设备A]interface gigabitethernet 1/0/3
[设备A-GigabitEthernet1/0/3] port link-aggregation group 1
[设备A-GigabitEthernet1/0/3] quit
[设备A]interface bridge-aggregation 1
[设备A-Bridge-Aggregation1] port link-type trunk
[设备A-Bridge-Aggregation1] port trunk permit vlan all
[设备A-Bridge-Aggregation1] quit
[设备A]save force

交换机B的配置

[设备B]interface bridge-aggregation 1
[设备B-Bridge-Aggregation1] link-aggregation mode dynamic
[设备B-Bridge-Aggregation1] quit
[设备B]interface gigabitethernet 1/0/1
[设备B-GigabitEthernet1/0/1] port link-aggregation group 1
[设备B-GigabitEthernet1/0/1] quit
[设备B]interface gigabitethernet 1/0/2
[设备B-GigabitEthernet1/0/2] port link-aggregation group 1
[设备B-GigabitEthernet1/0/2] quit
[设备B]interface gigabitethernet 1/0/3
[设备B-GigabitEthernet1/0/3] port link-aggregation group 1
[设备B-GigabitEthernet1/0/3] quit
[设备B]interface bridge-aggregation 1
[设备B-Bridge-Aggregation1] port link-type trunk
[设备B-Bridge-Aggregation1] port trunk permit vlan all (这里根据自己所需要的网络需求来配置允许哪些vlan通过
[设备B-Bridge-Aggregation1] quit
[设备B]save force

检查配置效果

[H3C]display link-aggregation verbose

结果说明

查看本端和对端设备上聚合组内的成员端口是否都处于Selected状态。状态一致说明成功配置好了链路聚合。
