首先配置一下交换机

SC-2950>

SC-2950>en

SC-2950#conf t

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

SC-2950(config)#config-register 0x2102

SC-2950(config)#end

添加三个VLAN

SC-2950#vlan data

SC-2950(vlan)#vlan 10 name v1

VLAN 10 added:

Name: v1

SC-2950(vlan)#vlan 20 name v2

VLAN 20 added:

Name: v2

SC-2950(vlan)#vlan 30 name v3

VLAN 30 added:

Name: v3

SC-2950(vlan)#exit

APPLY completed.

Exiting....

SC-2950#

划分接口到各个VLAN

SC-2950#conf t

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

SC-2950(config)#int fa0/1 //留给管理员

SC-2950(config-if)#switchport mode access

SC-2950(config-if)#sw acc vlan 10

SC-2950(config-if)#no shutdown

SC-2950(config-if)#exit

SC-2950(config)#int range f0/2 - 15

SC-2950(config-if-range)#sw mode acc

SC-2950(config-if-range)#sw acc vlan 20

SC-2950(config-if-range)#no sh

SC-2950(config-if-range)#exit

SC-2950(config)#int range f0/16 - 24

SC-2950(config-if-range)#sw mode acc

SC-2950(config-if-range)#sw acc vlan 30

SC-2950(config-if-range)#no sh

SC-2950(config-if-range)#exit

激活VLAN,并且给VLAN 10加个IP以便管理

SC-2950(config)#int vlan 10

SC-2950(config-if)#ip add 192.168.1.1 255.255.255.0

SC-2950(config-if)#no sh

SC-2950(config-if)#exit

SC-2950(config)#int vlan 20

SC-2950(config-if)#no sh

SC-2950(config-if)#exit

SC-2950(config)#int vlan 30

SC-2950(config-if)#no sh

SC-2950(config-if)#exit

将交换机指向网关

SC-2950(config)#ip default-gateway 192.168.1.254

SC-2950(config)#end

SC-2950#

检测配置

SC-2950#sh vlan brief
