链路聚合分为：静态链路聚合、动态链路聚合
链路聚合的负载分担模式：对于二层数据流，系统会根据MAC地址（源
mac地址和目的mac地址来计算），而对于三层数据流则会根据ip地址
来进行负载分担计算。
静态链路聚合实验：实验环境：H3C ENSP
配置要点：
第一步：创建链路聚合端口
：（系统模式）interface eth-trunk 2(端口号)
第二步：指定聚合端口的链路类型
：（聚合端口模式）port link-type trunk
第三步：如果聚合链路端口是trunk类型，则需要进一步指定允许相应
数据通过的vlan编号
：（聚合端口模式）port trunk allow-pass vlan 10(vlan号)
第四步：把接口加入到链路聚合端口中
：（接口模式）eth-trunk 2
