华为配置LACP模式的链路聚合示例

操作步骤
在AC1上创建Eth-Trunk1并配置为LACP模式。AC2配置过程与AC1类似，不再赘述
<HUAWEI> system-view [HUAWEI] sysname AC1 [AC1] interface eth-trunk 1 [AC1-Eth-Trunk1] mode lacp-static [AC1-Eth-Trunk1] quit
配置AC1上的成员接口加入Eth-Trunk。AC2配置过程与AC1类似，不再赘述
[AC1] interface gigabitethernet 0/0/1 [AC1-GigabitEthernet0/0/1] eth-trunk 1 [AC1-GigabitEthernet0/0/1] quit [AC1] interface gigabitethernet 0/0/2 [AC1-GigabitEthernet0/0/2] eth-trunk 1 [AC1-GigabitEthernet0/0/2] quit [AC1] interface gigabitethernet 0/0/3 [AC1-GigabitEthernet0/0/3] eth-trunk 1 [AC1-GigabitEthernet0/0/3] quit
在AC1上配置系统优先级为100，使其成为LACP主动端
[AC1] lacp priority 100
在AC1上配置活动接口上限阈值为2
[AC1] interface eth-trunk 1 [AC1-Eth-Trunk1] max active-linknumber 2 [AC1-Eth-Trunk1] quit
在AC1上配置接口优先级确定活动链路
[AC1] interface gigabitethernet 0/0/1 [AC1-GigabitEthernet0/0/1] lacp priority 100 [AC1-GigabitEthernet0/0/1] quit [AC1] interface gigabitethernet 0/0/2 [AC1-GigabitEthernet0/0/2] lacp priority 100 [AC1-GigabitEthernet0/0/2] quit
验证配置结果
# 查看各AC设备的Eth-Trunk信息，查看链路是否协商成功。

通过以上显示信息可以看到，AC1的系统优先级为100，高于AC2的系统优先级。Eth-Trunk的成员接口中GigabitEthernet0/0/1、GigabitEthernet0/0/2成为活动接口，处于“Selected”状态，接口GigabitEthernet0/0/3处于“Unselect”状态，同时实现M条链路的负载分担和N条链路的冗余备份功能。
