一、試驗拓撲

二,、試驗需求

PC1和PC3屬于VLAN 10 ,PC2和PC四屬于VLAN 20,，實現(xiàn)不同VLAN之間的相互通訊

三、試驗過程

配置三層交換機SW1

[Huawei]sysname S1
[S1]SYS S1
[S1]vlan b 10 20
Info: This operation may take a few seconds. Please wait for a moment...done.
[S1]int vlan 10
[S1-Vlanif10]ip add 192.168.10.1 24
[S1-Vlanif10]int vlan 20
[S1-Vlanif20]ip add 192.168.20.1 24
[S1-Vlanif20]int g0/0/1
[S1-GigabitEthernet0/0/1]port link-type trunk
[S1-GigabitEthernet0/0/1]port trunk allow-pass vlan 10 20
[S1-GigabitEthernet0/0/1]quit
[S1]int g0/0/2
[S1-GigabitEthernet0/0/2]port link-type trunk
[S1-GigabitEthernet0/0/2]port trunk allow-pass vlan 10 20
[S1-GigabitEthernet0/0/2]quit

1,、首先,，在三層交換機上新建vlan10、vlan20,，然后分別為vlan10和vlan20配置IP,。

2、其次,，設(shè)置g0/0/1,、g0/0/2端口為trunk模式，這兩trunk端口用于連接兩個二層交換機,，并且允許vlan10和vlan20通過,。（g0/0/1為1000Mb/s告訴口，E0/0/1為10Mb/s低速口）。

配置二層交換機SW2

<Huawei>undo ter m

<Huawei>sys
Enter system view, return user view with Ctrl+Z.
[Huawei]vlan b 10 20
Info: This operation may take a few seconds. Please wait for a moment...done.
[Huawei]int g0/0/1
[Huawei-GigabitEthernet0/0/1]port link-type trunk
[Huawei-GigabitEthernet0/0/1]port trunk allow-pass vlan 10 20 
[Huawei-GigabitEthernet0/0/1]int e0/0/1
[Huawei-Ethernet0/0/1]port link-type access
[Huawei-Ethernet0/0/1]port default vlan 10
[Huawei-Ethernet0/0/1]int e0/0/2
[Huawei-Ethernet0/0/2]port link-type access
[Huawei-Ethernet0/0/2]port default vlan 20
[Huawei-Ethernet0/0/2]qu

首先配置g0/0/1高速口為trunk模式,，并且允許vlan10,、vlan20的通過，該高速口用于連接三層交換機用,。

其次在二層交換機上指定e0/0/1口為access模式,，并將該口劃歸為vlan10,用于連接PC1（連接的電腦的地址須和vlan10的地址在一個網(wǎng)段內(nèi)）；指定e0/0/2口為access模式,，并將該口劃歸為vlan20,用于連接PC2,。

配置二層交換機SW3

<Huawei>sys

[Huawei]vlan batch 10 20
Info: This operation may take a few seconds. Please wait for a moment...done.
[Huawei]int g0/0/1
[Huawei-GigabitEthernet0/0/1]port link-type trunk
[Huawei-GigabitEthernet0/0/1]port trunk allow-pass vlan 10 20
[Huawei-GigabitEthernet0/0/1]quit
[Huawei]int e0/0/3
[Huawei-Ethernet0/0/3]port link-type access
[Huawei-Ethernet0/0/3]port default vlan 10
[Huawei-Ethernet0/0/3]qu
[Huawei]int e0/0/4
[Huawei-Ethernet0/0/4]port link-type access
[Huawei-Ethernet0/0/4]port default vlan 20
