VLAN实验

知识点

交换机的接口模式：

  • Access：用来连接终端，电脑，打印机

  • Trunk：用来连接其他的交换机

拓扑图1

实验步骤

1.按照拓扑图配置

2.用PC1去Ping PC2，是通的。

PC>ping 1.1.1.2

Ping 1.1.1.2: 32 data bytes, Press Ctrl_C to break
From 1.1.1.2: bytes=32 seq=1 ttl=128 time=47 ms
From 1.1.1.2: bytes=32 seq=2 ttl=128 time=47 ms
From 1.1.1.2: bytes=32 seq=3 ttl=128 time=47 ms
From 1.1.1.2: bytes=32 seq=4 ttl=128 time=31 ms
From 1.1.1.2: bytes=32 seq=5 ttl=128 time=46 ms

--- 1.1.1.2 ping statistics ---
  5 packet(s) transmitted
  5 packet(s) received
  0.00% packet loss
  round-trip min/avg/max = 31/43/47 ms

PC>

3.创建VLAN10和VLAN20

[Huawei]vlan 10
[Huawei-vlan10]q
[Huawei]vlan 20
[Huawei-vlan20]q

4.查看VLAN是否创建成功

[Huawei]disp vlan
The total number of vlans is : 3

20   common  

VID  Status  Property      MAC-LRN Statistics Description      
--------------------------------------------------------------------------------

1    enable  default       enable  disable    VLAN 0001                         
10   enable  default       enable  disable    VLAN 0010                         
20   enable  default       enable  disable    VLAN 0020

5.进入g0/0/1接口视图，将接口类型设置为access,将该接口划分到VLAN 10

[Huawei]int g0/0/1
[Huawei-GigabitEthernet0/0/1]port link-type access 
[Huawei-GigabitEthernet0/0/1]port default vlan 10

6.同样使用display vlan查看配置是否成功，可以看到g0/0/1口已经被划分到vlan10

[Huawei]dis vlan
The total number of vlans is : 3

10   common  UT:GE0/0/1(U)                                                      

20   common  

VID  Status  Property      MAC-LRN Statistics Description      
--------------------------------------------------------------------------------

1    enable  default       enable  disable    VLAN 0001                         
10   enable  default       enable  disable    VLAN 0010                         
20   enable  default       enable  disable    VLAN 0020

7.同样将g0/0/2口放入vlan20

[Huawei]int g0/0/2
[Huawei-GigabitEthernet0/0/2]port link-type access 
[Huawei-GigabitEthernet0/0/2]port default vlan 20

8.dis vlan

VID  Type    Ports

                GE0/0/19(D)     GE0/0/20(D)     GE0/0/21(D)     GE0/0/22(D)     
                GE0/0/23(D)     GE0/0/24(D)                                     

10   common  UT:GE0/0/1(U)                                                      

20   common  UT:GE0/0/2(U)

9.从PC1 Ping PC2

PC>ping 1.1.1.2

Ping 1.1.1.2: 32 data bytes, Press Ctrl_C to break
From 1.1.1.1: Destination host unreachable
From 1.1.1.1: Destination host unreachable
From 1.1.1.1: Destination host unreachable
From 1.1.1.1: Destination host unreachable
From 1.1.1.1: Destination host unreachable

--- 1.1.1.2 ping statistics ---
  5 packet(s) transmitted
  0 packet(s) received
  100.00% packet loss

拓扑图2

实验步骤

1.将PC3和PC4都划分到vlan10和vlan20中

[LSW2]int g0/0/2	
[LSW2-GigabitEthernet0/0/2]port link-type access 	
[LSW2-GigabitEthernet0/0/2]port default vlan 10
[LSW2-GigabitEthernet0/0/2]int g0/0/3
[LSW2-GigabitEthernet0/0/3]port link-type access
[LSW2-GigabitEthernet0/0/3]port default vlan 20

2.查看dis vlan，已经成功划分好vlan

The total number of vlans is : 3
--------------------------------------------------------------------------------
U: Up;         D: Down;         TG: Tagged;         UT: Untagged;
MP: Vlan-mapping;               ST: Vlan-stacking;
#: ProtocolTransparent-vlan;    *: Management-vlan;
--------------------------------------------------------------------------------

VID  Type    Ports                                                          
--------------------------------------------------------------------------------
1    common  UT:GE0/0/1(U)      GE0/0/4(D)      GE0/0/5(D)      GE0/0/6(D)      
                GE0/0/7(D)      GE0/0/8(D)      GE0/0/9(D)      GE0/0/10(D)     
                GE0/0/11(D)     GE0/0/12(D)     GE0/0/13(D)     GE0/0/14(D)     
                GE0/0/15(D)     GE0/0/16(D)     GE0/0/17(D)     GE0/0/18(D)     
                GE0/0/19(D)     GE0/0/20(D)     GE0/0/21(D)     GE0/0/22(D)     
                GE0/0/23(D)     GE0/0/24(D)                                     

10   common  UT:GE0/0/2(U)                                                      

20   common  UT:GE0/0/3(U)                                                      


VID  Status  Property      MAC-LRN Statistics Description      
--------------------------------------------------------------------------------

1    enable  default       enable  disable    VLAN 0001                         
10   enable  default       enable  disable    VLAN 0010                         
20   enable  default       enable  disable    VLAN 0020

3.尝试ping不通，是因为交换机之间还没有配置trunk

[LSw1]int g0/0/3	
[LSw1-GigabitEthernet0/0/3]port link-type trunk 
[LSw1-GigabitEthernet0/0/3]port trunk allow-pass vlan 10
[LSw1-GigabitEthernet0/0/3]port trunk allow-pass vlan 20
[LSW2]int g0/0/1	
[LSW2-GigabitEthernet0/0/1]port link-type trunk 
[LSW2-GigabitEthernet0/0/1]port trunk allow-pass vlan 10
[LSW2-GigabitEthernet0/0/1]port trunk allow-pass vlan 20

4.尝试在相同Vlan和不同VLAN之间Ping

PC>ping 1.1.1.3

Ping 1.1.1.3: 32 data bytes, Press Ctrl_C to break
From 1.1.1.3: bytes=32 seq=1 ttl=128 time=63 ms
From 1.1.1.3: bytes=32 seq=2 ttl=128 time=47 ms
From 1.1.1.3: bytes=32 seq=3 ttl=128 time=78 ms
From 1.1.1.3: bytes=32 seq=4 ttl=128 time=78 ms
From 1.1.1.3: bytes=32 seq=5 ttl=128 time=78 ms

--- 1.1.1.3 ping statistics ---
  5 packet(s) transmitted
  5 packet(s) received
  0.00% packet loss
  round-trip min/avg/max = 47/68/78 ms

PC>ping 1.1.1.4

Ping 1.1.1.4: 32 data bytes, Press Ctrl_C to break
From 1.1.1.1: Destination host unreachable
From 1.1.1.1: Destination host unreachable
From 1.1.1.1: Destination host unreachable
From 1.1.1.1: Destination host unreachable
From 1.1.1.1: Destination host unreachable
