Vlan和Trunk实验

Vlan和Trunk实验

一、拓扑图

二、实验需求

1. 按图示为PC端配置IP地址

2. sw1和sw2上分别创建vlan10和vlan20，要求PC3和PC5属于vlan10，PC4和PC6属于vlan20

3. sw1和sw2相连的接口配置为trunk类型，允许vlan10和vlan20通过

4. 测试效果，同一vlan的PC端可以互通，不同vlan的PC端无法互通

三、实验解法

1. PC端配置IP地址
   
   
   
   

2. sw1和sw2相连的接口配置为trunk类型

<H3C>sys
System View: return to User View with Ctrl+Z.
[H3C]sysn
[H3C]sysname sw1
[sw1]vlan 10
[sw1-vlan10]vlan 20
[sw1-vlan20]quit

<H3C>system-view 
System View: return to User View with Ctrl+Z.
 [H3C]sysname SW2
 [sw2]vlan 10
 [sw2-vlan10]vlan 20
 [sw2-vlan20]quit 

3. sw1和sw2都把g1/0/1接口加入vlan10,g1/0/2接口接入vlan20

[sw1]vlan 10
[sw1-vlan10]port GigabitEthernet 1/0/1
[sw1-vlan10]vlan 20
[sw1-vlan20]port GigabitEthernet 1/0/2
[sw1-vlan20]quit

[sw2]vlan 10
[sw2-vlan10]port GigabitEthernet 1/0/1
[sw2-vlan10]vlan 20
[sw2-vlan20]port GigabitEthernet 1/0/2
[sw2-vlan20]quit

4. sw1和sw2的g1/0/3接口都配置为trunk,允许vlan10和vlan20通过

   [sw1]interface GigabitEthernet 1/0/3
   [sw1-GigabitEthernet1/0/3]port link-type trunk
   [sw1-GigabitEthernet1/0/3]port trunk permit vlan 10 20
   [sw1-GigabitEthernet1/0/3]display this
   #
   interface GigabitEthernet1/0/3
    port link-mode bridge
    port link-type trunk
    port trunk permit vlan 1 10 20
    combo enable fiber
   #
   return
   [sw1-GigabitEthernet1/0/3]quit
   

   [sw2]interface GigabitEthernet 1/0/3
   [sw2-GigabitEthernet1/0/3]port link-type trunk
   [sw2-GigabitEthernet1/0/3]port trunk permit vlan 10 20
   [sw2-GigabitEthernet1/0/3]display this
   #
   interface GigabitEthernet1/0/3
    port link-mode bridge
    port link-type trunk
    port trunk permit vlan 1 10 20
    combo enable fiber

   return
   [sw2-GigabitEthernet1/0/3]quit
   

   5. 测试结果，如下图所示，PC3可以ping通PC5，但无法ping通PC4和PC6
