链路聚合实验

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
静态端口聚合（两台交换机都按照下面的命令配置）

<H3C>sys
System View: return to User View with Ctrl+Z.
[H3C]sysname SW1
[SW1]interface Bridge-Aggregation 1
[SW1-Bridge-Aggregation1]port link-type trunk
[SW1-Bridge-Aggregation1]port trunk permit vlan all \\默认模式为静态所以不需要修改模式了
[SW1-Bridge-Aggregation1]link-aggregation mode static \\如果原本为动态则使用该命令进行修改


#将 g1/0/1和g1/0/2加入链路聚合组1
[SW1]interface GigabitEthernet 1/0/1
[SW1-GigabitEthernet1/0/1]port link-type trunk
[SW1-GigabitEthernet1/0/1]port trunk permit vlan all
[SW1-GigabitEthernet1/0/1]port link-aggregation group 1
[SW1-GigabitEthernet1/0/1]qu
[SW1]interface GigabitEthernet 1/0/2
[SW1-GigabitEthernet1/0/2]port link-type trunk
[SW1-GigabitEthernet1/0/2]port trunk permit vlan all
[SW1-GigabitEthernet1/0/2]port link-aggregation group 1
Can't assign the port to the aggregation group because its attribute configurations are different than the aggregate interface.

动态端口聚合（两台交换机都按照下面的命令配置）

<H3C>sys
System View: return to User View with Ctrl+Z.
[H3C]sysname SW1
[SW1]interface Bridge-Aggregation 1
[SW1-Bridge-Aggregation1]port link-type trunk
[SW1-Bridge-Aggregation1]port trunk permit vlan all
[SW1-Bridge-Aggregation1]link-aggregation mode dynamic \\将聚合模式设置为动态
[SW1-Bridge-Aggregation1]qu

[SW1]interface g1/0/1
[SW1-GigabitEthernet1/0/1]port link-type trunk
[SW1-GigabitEthernet1/0/1]port trunk permit vlan all
[SW1-GigabitEthernet1/0/1]port link-aggregation group 1
[SW1-GigabitEthernet1/0/1]qu
[SW1]interface g1/0/2

三层聚合命令

在交换机上配置三层链路聚合

<H3C>sys
System View: return to User View with Ctrl+Z.
[H3C]sysname SW1
[SW1]interface Route-Aggregation 1
[SW1-Route-Aggregation1]ip add 192.168.1.1 24
[SW1-Route-Aggregation1]qu

[SW1]int GigabitEthernet 1/0/1
[SW1-GigabitEthernet1/0/1]port link-mode route //这里要将端口转换成三层端口
[SW1-GigabitEthernet1/0/1]port link-aggregation group 1
[SW1-GigabitEthernet1/0/1]qu
[SW1]int GigabitEthernet 1/0/2
[SW1-GigabitEthernet1/0/2]port link-mode route //这里要将端口转换成三层端口
the interface GigabitEthernet1/0/2 changed to down.
[SW1-GigabitEthernet1/0/2]qu
[SW1]int GigabitEthernet 1/0/2
[SW1-GigabitEthernet1/0/2]port link-aggregation group 1
