H3C Cloud Lab交换机VLAN划分

单交换机VLAN划分

实验拓扑：

要求：PC1能和PC4通信但是不能和PC2、PC3通信

PC2能和PC3通信但是不能和PC1、PC4通信

S1配置：

<H3C>sys
System View: return to User View with Ctrl+Z.
[H3C]sysname S1
[S1]vlan 10
[S1-vlan10]port GigabitEthernet 1/0/1
[S1-vlan10]port GigabitEthernet 1/0/4
[S1-vlan10]vlan 20
[S1-vlan20]port g 1/0/2
[S1-vlan20]port g 1/0/3
[S1-vlan20]dis vlan
Total VLANs: 3
The VLANs include:
1(default), 10, 20
[S1-vlan20]dis vlan all
