两台思科交换机vlan划分_思科交换机划分vlan配置实例

VLAN是一种比较新的&＃39;技术&＃xff0c;工作在OSI参考模型的第2层和第3层&＃xff0c;一个VLAN就是一个广播域&＃xff0c;VLAN之间的通信是通过第3层的路由器来完成的。那么在思科交换机上怎么划分vlan&＃xff0c;一起来看看吧!

//添加vlan

Switch>enable

Switch#vlan data

Switch(vlan)#vlan 10 name v1

VLAN 10 added:

Name: v1

Switch(vlan)#vlan 20 name v2

VLAN 20 added:

Name: v2

Switch(vlan)#vlan 30 name v3

VLAN 30 added:

Name: v3

Switch(vlan)#exit

APPLY completed.

Exiting…

//为vlan添加接口

Switch#config t

Enter configuration commands, one per line. End with CNTL/Z.

Switch(config)#int f0/1

Switch(config-if)#switchport mode access

Switch(config-if)#switchport acc vlan 10

Switch(config-if)#no shutdown

Switch(config-if)#exit //留给管理员用

Switch(config)#int range f0/2-15

Switch(config-if-range)#switchport mode acc

Switch(config-if-range)#switchport acc vlan 20

Switch(config-if-range)#no sh

Switch(config-if-range)#exit

Switch(config)#int range f0/16-24

Switch(config-if-range)#switchport mode access

Switch(config-if-range)#switchport access vlan 30

Switch(config-if-range)#no sh

Switch(config-if-range)#exit

//激活vlan,并且给vlan 10 添加ip以便管理

Switch(config)#int vlan 10

Switch(config-if)#ip add 192.168.1.1 255.255.255.0 //给vlan 10 添加ip以便管理

Switch(config-if)#no sh

Switch(config-if)#exit

Switch(config)#int vlan 20

Switch(config-if)#no sh

Switch(config-if)#exit

Switch(config)#int vlan 30

Switch(config-if)#no sh ^

Switch(config-if)#exit

//指定网关

Switch(config)#ip default-gateway 192.168.1.254

Switch(config)#end

//检测配置

Switch#show vlan brief

//以上为检测结果

Switch#

//保存配置

Switch#write

Building configuration…

[OK]

Switch#

补充&＃xff1a;

//删除一个接口的vlan

Switch>enable

Switch#config

Configuring from terminal, memory, or network [terminal]?

Enter configuration commands, one per line. End with CNTL/Z.

Switch(config)#int f0/5

Switch(config-if)#no switchport access vlan

Switch(config-if)#end

Switch#

检查一个特定端口的生成树信息

Switch#show spanning-tree ?

Switch#show spanning-tree vlan ? 指定vlan显示其STP配置

Switch#show spanning-tree vlan 10
