vlan 和 trunk 实验

实验拓扑图

实验拓扑.png

实验需求

按图示为PC配置IP地址
SW1和SW2上分别创建vlan10和vlan20，要求PC3和PC5属于vlan10，PC4和PV6属于vlan20
SW1和SW2相连的接口配置为trunk类型，允许vlan10和vlan20通过
测试效果，同一vlan的PC可以互通，不同vlan的PC无法互通

实验解法

1.PC配置IP地址命令
  略
2.SW1和SW2上分别创建vlan10和vlan20
 步骤一：
  进入系统视图模式  system-view
  更改交换机设备名称 sysname SW1
 步骤二：
  在SW1和SW2上设置创建vlan 10，vlan 20

[SW1]vlan 10
[SW1-vlan10]vlan 20
[SW1-vlan10]quit

 步骤三：
  查看已经设置好的vlan

[SW1]display vlan
[SW1]display vlan brief

3.SW1把g1/0/1接口加入vlan10，g1/0/2接口加入vlan20;SW2把g1/0/2接口加入vlan10，把g1/0/3接口加入vlan20

[SW1]vlan 10
[SW1-vlan10]port g1/0/1
[SW1-vlan10]vlan 20
[SW1-vlan20]port g1/0/2

4.SW1的g1/0/3接口,SW2的G1/0/1接口都配置为trunk，允许vlan10和vlan20通过

[SW1]interface g1/0/3
[SW1-GigabitEthernet1/0/3]port link-type trunk

[SW1-GigabitEthernet1/0/3]port trunk permit vlan 10 20

5.**测试结果，如下所示，PC3可以PING通PC5，但无法PING通PC4和PC6
