华三交换机配置链路聚合

• 二层聚合配置

1、聚合方式：

（1）lacp

静态链路聚合

动态链路聚合（开启lacp模式，常用）

（2）手工负载分担

2、配置步骤

静态端口聚合（两台交换机都按照下面命令配置）

//创建静态链路聚合口1，不启用lacp
 
[SWB]interface Bridge-Aggregation 1       
[SWB-Bridge-Aggregation1]port link-type trunk
[SWB-Bridge-Aggregation1]port trunk permit vlan all
[SWB-Bridge-Aggregation1]link-aggregation mode static  //聚合口设置成静态（默认就是静态，此处这条命令可以不写）
 
 
//把 1 2口加入 聚合口1
[SWB]interface Ethernet 1/0/1
[SWB-Ethernet1/0/1]port link-aggregation group 1
[SWB-Ethernet1/0/1]quit
[SWB]interface Ethernet 1/0/2
[SWB-Ethernet1/0/2]port link-aggregation group 1

查看链路聚合的状态，1口和2口都是工作状态

动态端口聚合 （两台交换机都按照下面命令配置，

//创建动态链路聚合口1，启用lacp
 
[SWB]interface Bridge-Aggregation 1       
[SWB-Bridge-Aggregation1]port link-type trunk
[SWB-Bridge-Aggregation1]port trunk permit vlan all
[SWB-Bridge-Aggregation1]link-aggregation mode dynamic  //聚合口设置成动态，即lacp，常用这种
 
 
//把 1 2口加入 聚合口1
[SWB]interface Ethernet 1/0/1
[SWB-Ethernet1/0/1]port link-aggregation group 1
[SWB-Ethernet1/0/1]quit
[SWB]interface Ethernet 1/0/2
[SWB-Ethernet1/0/2]port link-aggregation group 1

查看动态链路聚合状态，状态为动态

负载分担

//创建动态链路聚合口1
 
[SWB]interface Bridge-Aggregation 1       
[SWB-Bridge-Aggregation1]port link-type trunk
[SWB-Bridge-Aggregation1]port trunk permit vlan all
 
 
//把 1 2口加入 聚合口1
[SWB]interface Ethernet 1/0/1
[SWB-Ethernet1/0/1]port link-aggregation group 1
[SWB-Ethernet1/0/1]quit
[SWB]interface Ethernet 1/0/2
[SWB-Ethernet1/0/2]port link-aggregation group 1

[SWA]link-aggregation load-sharing mode destination-mac 两端都配置

三层聚合命令

interface Route-Aggregation10                  //创建三层聚合口 10
 ip address 192.168.100.2 255.255.255.0        //配置ip地址
 
interface rang gig1/0/1 gig1/0/2    
  port link-mode route                       //把端口 1 2 改成三层口
  port link-Aggregation group 10             //加入聚合口10
