ensp-----链路聚合实验

一.实验原理

• 以太网链路聚合：Eth-Trunk简称链路聚合，它通过将多条以太网物理链路捆绑在一起成为一条逻辑链路，从而实现增加链路带宽的母的。此外，这些捆绑在一起的链路通过相互的动态备份，有效的提高了链路的可靠性
• 链路聚合分为手工模式和LACP模式
• LACP模式需要有链路聚合控制协议LACP的参与。当需要在两个直连设备间提供一个较大的链路带宽而设备支持LACP协议时，建议使用LACP模式。LACP模式不仅可以实现增加带宽、提高可靠性、负载分担的目的，而且可以提高Eth-Trunk的容错性、提供备份功能
• LACP模式下，部分是活动链路，所有活动链路均参与数据转发。如果某条活动链路故障，链路聚合组自动在非活动链路中选择一条链路作为活动链路，参与数据转发的链路数目不变
• 链路捆绑有二层设备之间的链路捆绑，三层设备之间的捆绑，二层设备和三层设备之间的捆绑
