Ensp模拟器VLAN 技术
一:实验要求:
能使相同的VLAN之间正常通讯
二:所需设备:
使用Ensp模拟两个S3700交换机,四台PC机
三:技术解释:
使用VLAN技术,屏蔽广播风暴
四:实验拓扑:
五:实验步骤:
1.开启所有设备
2.给LSW1更改主机名为sw1 ,LSW2更改为sw2
[Huawei]sysname sw1
[sw1]
[Huawei]sysname sw2
[sw2]
3.给LSW1添加VLAN10 和 VLAN 20
[sw1]VLAN 10 //在特权模式下新建VLAN10
[sw1-vlan10] //进入VLAN10
[sw1-vlan10]VLAN 20 //新建VLAN20
[sw1-vlan20] //进入VLAN20
4.给 LSW2添加 VLAN10和VLAN20
[sw2]vlan 10
[sw2-vlan10]
[sw2-vlan10]VLAN 20
[sw2-vlan20]
5.在LSW1中将PC1加入VLAN 10 PC2加入VLAN 20
[sw1-vlan20]int e0/0/2
[sw1-Ethernet0/0/2]port link-type access
[sw1-Ethernet0/0/2]port default vlan 10
[sw1-Ethernet0/0/2]int e0/0/3
[sw1-Ethernet0/0/3]port link-type access
[sw1-Ethernet0/0/3]port default vlan 20
[sw1-Ethernet0/0/3]
查看VLAN10 VLAN20
[sw1-Ethernet0/0/3]dis vlan
反馈信息的一部分:
-----------------------------------------------------------------1 common UT:Eth0/0/1(U) Eth0/0/4(D) Eth0/0/5(D) 10 common UT:Eth0/0/2(U)
20 common UT:Eth0/0/3(U)
6.在LSW2中将PC3加入VLAN 10 PC4加入VLAN 20
[sw2]int e0/0/2
[sw2-Ethernet0/0/2]port link-type access
[sw2-Ethernet0/0/2]port default vlan 10
[sw2-Ethernet0/0/2]int e0/0/3
[sw2-Ethernet0/0/3]port link-type access
[sw2-Ethernet0/0/3]port default vlan 20
[sw2-Ethernet0/0/3]
7.在SW1与SW2之间都配置中继口
[sw1-Ethernet0/0/3]int e0/0/1
[sw1-Ethernet0/0/1]port link-type trunk
[sw1-Ethernet0/0/1]port trunk allow-pass vlan all
[sw2-Ethernet0/0/3]int e0/0/1
[sw2-Ethernet0/0/1]port link-type trunk
[sw2-Ethernet0/0/1]port trunk allow-pass vlan all
8.验证:能使PC1 ping PC3 ,PC1不能 ping通 PC2
