链路聚合LACP模式配置

1 问题
交换机之间的链路如何通过自动方式实现链路的捆绑？
配置思路：
1.终端pc设置
2.交换机设置
-建立vlan 10 20
-pc与交换机接口设置acc加入对应vlan
-创建eth-trunk1
-设置手工分担模式
[SW1-Eth-Trunk1]mode lacp-static /设置自动工作模式
-添加成员进入trunkport g0/0/1
-在int eth-trunk 1 接口设置trunk 允许vlan all
-[SW2]lacp priority 100 /设置优先级100
-[SW2-Eth-Trunk2]max active-linknumber 2 /设置链路最大连接数
-[SW2-Eth-Trunk2]lacp preempt enable /设置抢占功能 要求两个交换机都要设置

[SW1]int g0/0/4
