链路聚合是网络工程中常用的技术手段，可以有效提高链路带宽并提供链路冗余。本文将通过具体的配置命令和示例，详细介绍如何在华为交换机上实现链路聚合。

链路聚合的好处

1. 提高带宽
2. 链路冗余

SW_2的配置

<Huawei>sys
[Huawei]sys SW_2
[SW_2]vlan batch 10 20
[SW_2]int g0/0/4
[SW_2-GigabitEthernet0/0/4]port link-type access
[SW_2-GigabitEthernet0/0/4]port default vlan 10
[SW_2-GigabitEthernet0/0/4]int g0/0/5
[SW_2-GigabitEthernet0/0/5]port link-type access
[SW_2-GigabitEthernet0/0/5]port default vlan 20
[SW_2-GigabitEthernet0/0/5]quit
[SW_2]int Eth-Trunk 1   //创建编号为1的聚合口
[SW_2-Eth-Trunk1]port link-type trunk
[SW_2-Eth-Trunk1]port trunk allow-pass vlan all
[SW_2-Eth-Trunk1]int g0/0/1
[SW_2-GigabitEthernet0/0/1]eth-trunk 1  // g0/0/1加入编号为1的聚合口
[SW_2-GigabitEthernet0/0/1]int g0/0/2
[SW_2-GigabitEthernet0/0/2]eth-trunk 1
[SW_2-GigabitEthernet0/0/2]int g0/0/3
[SW_2-GigabitEthernet0/0/3]eth-trunk 1  

SW_3的配置

<Huawei>sys
[Huawei]sys SW_3
[SW_3]vlan batch 10 20
[SW_3]int vlan 10
[SW_3-Vlanif10]ip add 192.168.1.254 24
[SW_3-Vlanif10]int vlan 20
[SW_3-Vlanif20]ip add 192.168.2.254 24
[SW_3-GigabitEthernet0/0/1]quit
[SW_3]int Eth-Trunk 1
[SW_3-Eth-Trunk1]port link-type trunk
[SW_3-Eth-Trunk1]port trunk allow-pass vlan all
[SW_3-Eth-Trunk1]int g0/0/1
[SW_3-GigabitEthernet0/0/1]eth-trunk 1
[SW_3-GigabitEthernet0/0/1]int g0/0/2
[SW_3-GigabitEthernet0/0/2]eth-trunk 1
[SW_3-GigabitEthernet0/0/2]int g0/0/3
[SW_3-GigabitEthernet0/0/3]eth-trunk 1
[SW_3-GigabitEthernet0/0/3]  

测试验证

一条链路1G，汇聚后变3G

Ping测试

模拟g0/0/1的链路出现故障后，再Ping

[SW_2]int g0/0/1  
[SW_2-GigabitEthernet0/0/1]shutdown
