实验环境：两台H3C E126A，Ethernet1/0/24、Ethernet1/0/23汇聚为一条链路。
手工汇聚：

启动某端口的LACP协议后，该端口将通过发送LACPDU向对端通告自己的系统优先级、系统MAC、端口优先级、端口号和操作Key。对端接收到这些信息后，将这些信息与其它端口所保存的信息比较以选择能够汇聚的端口，从而双方可以对端口加入或退出某个动态汇聚组达成一致。
按照汇聚方式的不同，端口汇聚可以分为三类：手工汇聚、静态LACP汇聚、动态LACP汇聚。

链路聚合（端口汇聚）配置
端口汇聚是将多个以太网端口汇聚在一起形成一个逻辑上的汇聚组，使用汇聚服务的上层实体把同一汇聚组内的多条物理链路视为一条逻辑链路。
端口汇聚可以实现流量在汇聚组中各个成员端口之间进行分担，以增加带宽。同时，同一汇聚组的各个成员端口之间彼此动态备份，提高了连接可靠性。

基于IEEE802.3ad标准的LACP（Link Aggregation Control Protocol，链路汇聚控制协议）是一种实现链路动态汇聚与解汇聚的协议。LACP协议通过LACPDU（Link Aggregation Control Protocol Data Unit，链路汇聚控制协议数据单元）与对端交互信息。
