配置LACP模式的跨设备链路聚合（单机）示例
组网需求
如图3-22所示，DeviceA双归接入DeviceB和DeviceC，在DeviceA上部署LACP模式的Eth-Trunk接口，成员口分别与DeviceB和DeviceC的10GE1/0/1～10GE1/0/2连接，10GE1/0/1～10GE1/0/2的接口速率和双工模式相同，现在需要使流量可以在两台设备上负载分担。
配置思路
采用如下的思路配置跨设备LACP模式链路聚合：
分别在DeviceA、DeviceB、DeviceC上创建Eth-Trunk1，并配置为静态LACP模式，将成员接口加入Eth-Trunk1，实现链路聚合功能。
在DeviceB和DeviceC上配置相同的LACP系统ID。
在DeviceB和DeviceC上配置相同的系统LACP优先级。
在DeviceC上配置Eth-Trunk成员接口在LACP协议中的编号扩展，使成员接口编号均增加32768，避免和设备DeviceB上的成员接口在LACP协议中的编号相同。
操作步骤
- 分别在DeviceA、DeviceB和DeviceC上创建Eth-Trunk1并配置为LACP模式，并将成员口加入Eth-Trunk1。

- 配置DeviceB和DeviceC的系统ID为00e0-cf00-0000。

- 在DeviceB和DeviceC上配置系统LACP优先级为100。
[~DeviceB] lacp priority 100 [*DeviceB] commit
[~DeviceC] lacp priority 100 [*DeviceC] commit
- 在DeviceC上配置Eth-Trunk成员接口编号扩展，使成员接口编号均增加32768。
[~DeviceC] interface eth-trunk 1 [~DeviceC-Eth-Trunk1] lacp port-id-extension enable [*DeviceC-Eth-Trunk1] commit
- 验证配置结果

通过以上显示信息可以看到，各Device的Operating Status均为Up，表明Eth-Trunk1已经协商成功。DeviceB和DeviceC上的成员接口成为活动接口，处于“Selected”状态，表示DeviceB和DeviceC上的成员接口均可以负载分担。DeviceC的PortNo显示成员口的LACP编号已经增加32768。
