######1. 设置手工模式聚合链路###### ######2. 查看接口######

具体实施

设置手工动模式聚合链路

##### SW1: ##### [SW1]int Eth-Trunk 1 // [SW1-Eth-Trunk1]mode manual load-balance //设置模式（手动模式为默认模式） [SW1-Eth-Trunk1]trunkport Ethernet 0/0/1 to 0/0/4 或者分别进入不同端口，确认后输入eth-trunk 1//将4个接口加入聚合链路1


SW2:
[SW2]int Eth-Trunk 2
[SW2-Eth-Trunk2]mode manual load-balance
[SW2-Eth-Trunk2]trunkport  Ethernet 0/0/1 to 0/0/4
查看接口
SW1:
[SW1]dis eth-trunk 1

Ethernet0/0/4 Up  1
SW2:
[SW2]dis eth-trunk 2
Eth-Trunk2's state information is:

Least Active-linknumber: 1  Max Bandwidth-affected-linknumber: 8  
Operate status: up  Number Of Up Port In Trunk: 4

具体实施

将各个接口退出手工聚合链路

##### SW1: ##### [SW1]int e0/0/1 [SW1-Ethernet0/0/1]undo eth-trunk [SW1]int e0/0/2 [SW1-Ethernet0/0/2]undo eth-trunk [SW1]int e0/0/3 [SW1-Ethernet0/0/3]undo eth-trunk [SW1]int e0/0/4 [SW1-Ethernet0/0/4]undo eth-trunk ##### SW2: ##### [SW2]int e0/0/1 [SW2-Ethernet0/0/1]undo eth-trunk [SW2]int e0/0/2 [SW2-Ethernet0/0/2]undo eth-trunk [SW2]int e0/0/3 [SW2-Ethernet0/0/3]undo eth-trunk [SW2]int e0/0/4 [SW2-Ethernet0/0/4]undo eth-trunk


设置LACP模式聚合链路

##### SW1: ##### [SW1]int Eth-Trunk 1 [SW1-Eth-Trunk1]mode lacp-static [SW1-Eth-Trunk1]trunkport Ethernet 0/0/1 to 0/0/4 ##### SW2: ##### [SW2]int Eth-Trunk 2 [SW2-Eth-Trunk2]mode lacp-static [SW2-Eth-Trunk2]trunkport Ethernet 0/0/1 to 0/0/4


比较优先级确认主动端

**设置主动端需要比较优先级，因SW1与SW2的优先级都是默认的32768，故需要对比MAC地址大小。**

SW1:
[SW1]dis int Ethernet 0/0/1
Ethernet0/0/1 current state : UP
Line protocol current state : UP

SW2:
[SW2]dis int Ethernet 0/0/1
Ethernet0/0/1 current state : UP
Line protocol current state : UP
Description:
Switch Port, TPID : 8100(Hex), The Maximum Frame Length is 9216

由结果可看出SW1的MAC地址是4c1f-ccdc-53b6，SW2的MAC地址是4c1f-cc88-04f1，通过比较可知SW2的MAC地址较小，故SW2的优先级更高，应设为主动端。

设置活跃接口数目

##### SW1: ##### [SW1]int Eth-Trunk 1 [SW1-Eth-Trunk1]max active-linknumber 2 //最好两边设备都设置 ##### SW2: ##### [SW2]int Eth-Trunk 2 [SW2-Eth-Trunk2]max active-linknumber 2


设置e0/0/1和e0/0/3为活跃接口

**设置活跃接口需要比较优先级，因此时优先级均为默认值，接口依照接口号设置接口e0/0/1与e0/0/2为活跃接口。若要将接口e0/0/3设为活跃接口则需要修改优先级。**


SW2:
[SW2]int e0/0/3
[SW2-Ethernet0/0/3]lacp priority 100   //更改e0/0/3的优先级为100
[SW2-Ethernet0/0/3]q
[SW2]int Eth-Trunk 2
[SW2-Eth-Trunk2]lacp preempt enable     //开启抢占
[SW2-Eth-Trunk2]lacp preempt delay 10  //设置抢占延迟为10s
SW1:
[SW1]int Eth-Trunk 1
[SW1-Eth-Trunk1]lacp preempt enable   //两边设备都设置
[SW1-Eth-Trunk1]lacp preempt delay 10
查看接口
