1.基础配置
PC1 10.1.1.1 255.255.255.0
PC2 10.1.1.2 255.255.255.0
PC3 10.1.1.3 255.255.255.0
PC4 10.1.1.4 255.255.255.0
2.创建VLAN，配置Access接口
开发组属于VLAN 10
运维组属于VLAN 20
SW1,SW2,SW3 分别执行如下命令
<Huawei>system-view
[Huawei]undo info-center enable
[Huawei]vlan 10
[Huawei-vlan10]description R$D
[Huawei-vlan10]quit
[Huawei]vlan 20
[Huawei-vlan20]description Market
3. SW1,SW2配置Access接口，并划分相应的VLAN
SW1
[Huawei]interface Ethernet 0/0/2
[Huawei-Ethernet0/0/2]port link-type access
[Huawei-Ethernet0/0/2]port default vlan 10
[Huawei-Ethernet0/0/2]quit
[Huawei]interface Ethernet 0/0/3
[Huawei-Ethernet0/0/3]port link-type access
[Huawei-Ethernet0/0/3]port default vlan 20
SW2
[Huawei]interface Ethernet 0/0/3
[Huawei-Ethernet0/0/3]port link-type access
[Huawei-Ethernet0/0/3]port default vlan 10
[Huawei-Ethernet0/0/3]quit
[Huawei]interface Ethernet 0/0/4
[Huawei-Ethernet0/0/4]port link-type access
[Huawei-Ethernet0/0/4]port default vlan 20
4.配置Trunk接口
此时PC1 ping不通 PC3
在SW1配置E0/0/1为Trunk口，允许VLAN10和VLAN20通过。
[Huawei]interface Ethernet 0/0/1
[Huawei-Ethernet0/0/1]port link-type trunk
[Huawei-Ethernet0/0/1]port trunk allow-pass vlan 10 20
[Huawei-Ethernet0/0/1]
在SW2配置E0/0/1为Trunk口，允许VLAN10和VLAN20通过。
[Huawei]interface Ethernet 0/0/1
[Huawei-Ethernet0/0/1]port link-type trunk
[Huawei-Ethernet0/0/1]port trunk allow-pass vlan 10 20
[Huawei-Ethernet0/0/1]
在SW3配置GE 0/0/1和0/0/2 配置为Trunk接口，允许所用VLAN通过。
[Huawei]interface GigabitEthernet 0/0/1
[Huawei-GigabitEthernet0/0/1]port link-type trunk
[Huawei-GigabitEthernet0/0/1]port trunk allow-pass vlan all
[Huawei-GigabitEthernet0/0/1]quit
[Huawei]interface gigabitEthernet 0/0/2
[Huawei-GigabitEthernet0/0/2]port link-type trunk
[Huawei-GigabitEthernet0/0/2]port trunk allow-pass vlan all
[Huawei-GigabitEthernet0/0/2]quit
此时PC1pingPC3
示例4
1.分别在S1交换机上，创建VLAN10和VLAN20。(S2也执行此步)
vlan batch 10 20
2.进入进入GigabitEthernet 0/0/2接口，配置接口的链路类型，
然后配置Access类型接口加入VLAN10。GigabitEthernet 0/0/3接口的配置同GigabitEthernet 0/0/2接口
[S1]interface GigabitEthernet0/0/2
[S1-GigabitEthernet0/0/2]port link-type access
[S1-GigabitEthernet0/0/2]port default vlan 10
[S1-GigabitEthernet0/0/2]quit
[S1]
[S1]interface GigabitEthernet0/0/3
[S1-GigabitEthernet0/0/3]port link-type access
[S1-GigabitEthernet0/0/3]port default vlan 10
[S1-GigabitEthernet0/0/3]quit
3.进入GigabitEthernet 0/0/4接口，配置接口的链路类型，然后配置Access类型接口加入VLAN20
[S1]interface GigabitEthernet0/0/4
[S1-GigabitEthernet0/0/4]port link-type access
[S1-GigabitEthernet0/0/4]port default vlan 20
[S1-GigabitEthernet0/0/4]quit
4.进入GigabitEthernet 0/0/1接口，配置接口的链路类型，然后配置Trunk类型接口加入VLAN10和VLAN20
[S1]interface GigabitEthernet0/0/1
[S1-GigabitEthernet0/0/1]port link-type trunk
[S1-GigabitEthernet0/0/1]port trunk allow-pass vlan 10 20
[S1-GigabitEthernet0/0/1]quit
5.S2交换机
<Huawei>system-view
[Huawei]sysname S2
[S2]
[S2]interface GigabitEthernet0/0/2
[S2-GigabitEthernet0/0/2]quit
[S2]vlan batch 10 20
Info: This operation may take a few seconds. Please wait for a moment...done.
[S2]interface GigabitEthernet0/0/2
[S2-GigabitEthernet0/0/2]port link-type access
[S2-GigabitEthernet0/0/2]port default vlan 10
[S2-GigabitEthernet0/0/2]quit
[S2]
[S2]interface GigabitEthernet0/0/3
[S2-GigabitEthernet0/0/3]port link-type access
[S2-GigabitEthernet0/0/3]port default vlan 20
[S2-GigabitEthernet0/0/3]quit
[S2]
[S2]interface GigabitEthernet0/0/1
[S2-GigabitEthernet0/0/1]port link-type trunk
[S2-GigabitEthernet0/0/1]port trunk allow-pass vlan 10 20
[S2-GigabitEthernet0/0/1]quit
PC1 ping PC4
三层交换机可以充当路由器的作用，在LSW2交换机上配置VLAN10和VLAN20的IP地址（网关），实现两台交换机上的VLAN间能够通信。
[S2]interface Vlanif 10
[S2-Vlanif10]ip address 192.168.10.1 24
[S2-Vlanif10]quit
[S2]interface Vlanif 20
[S2-Vlanif20]ip address 192.168.30.1 24
[S2-Vlanif20]quit
[S2]
