静态LACP链路聚合模式和手动负载均衡链路聚合模式的主要区别：在LACP模式中，一些链路充当备份链路；在手动负载均衡模式中，所有的成员口都处于转发状态。
一、示例展示的要点：
1. 路由器和路由器链路聚合；
2. 路由器和交换机链路聚合；
3. 交换机和交换机链路聚合；
4. 手动负载分担模式；
5.静态LACP模式（配置设备优先级用于选出主设备，配置端口优先级用于指定备份链路）。
二、示例场景
为实现提高网络带宽和链路备份。

六、测试验证
使用display eth-trunk 命令查看Eth-Trunk 1接口状态，测试聚合链路备用端口切换启用。
如果将SW1的GE 0/0/2端口down掉：
开启SW1的GE 0/0/2端口：
SW1的GE 0/0/2端口从故障状态恢复正常后，没有自动变成活动状态。
使用display interface eth-trunk 命令查看Eth-Trunk 1接口信息
Eth-Trunk 3为2G，是两个GE端口带宽之和，GE0/0/3接口为Eth-Trunk 3的备用接口。
