H3C switch configuration link aggregation

H3C and Huawei switches are called link aggregation,
Cisco switches are called port aggregation

Layer 2 aggregation configuration

1. Polymerization method:

（1）、lacp

static link aggregation

Dynamic link aggregation (enable lacp mode, commonly used)

(2), manual load sharing

2. Configuration steps

Static port aggregation (both switches are configured according to the following commands)

//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

Check the status of link aggregation, both port 1 and port 2 are working

Dynamic port aggregation (both switches are configured according to the following commands,

//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

View the status of dynamic link aggregation, the status is dynamic

load sharing

//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 is configured at both ends

Three-tier aggregation command

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
