要求:设置sw3为VTP server,设置sw1和sw2为VTP client,域名为cisco,密码为:cisco,在server创建vlan 10(name:aa)和vlan20(name:bb);设置sw3为vlan1的根桥,sw1为vlan10的根桥,sw2为vlan20的根桥;
![实验一、配置STP与VTP_网络交换](http://l.thec.cn/walkbird/FileImg/配置STP与VTP.jpg)
Sw#Delete vlan.dat 用此命令将vlan删除
Sw#show startup-config 查看一下NVRAM是否保存了配置
Sw#erase startup-config 清空配置文件
Sw#reload 重新启动交换机
sw>enable
sw#config terminal
sw(config)#hostname sw1
sw1(config)#no ip domain-lookup 关闭域名查找
sw1(config)#line console 0
sw1(config-line)#logging synchronous 命令输入达到同步
sw1(config-line)#exec-timeout 0 0 设置永不超时
sw1(config-line)#exit
sw3(config)#vtp mode server 在sw3上启用vtp server
Device mode already VTP SERVER.
sw3(config)#vtp domain cisco 设置域名
Changing VTP domain name from NULL to cisco
sw3(config)#vtp password cisco 设置密码
Setting device VLAN database password to cisco
sw1#vlan database 进入vlan数据库
sw1(vlan)#vtp client 启用VTP client模式
Setting device to VTP CLIENT mode.
sw1(vlan)#vtp domain cisco 作用到cisco域中
Changing VTP domain name from NULL to cisco
sw1(vlan)#vtp password cisco 设置密码与server端相同
Setting device VLAN database password to cisco.
sw1(vlan)#exit 使配置生效
In CLIENT state, no apply attempted.
Exiting....
sw2#vlan database
sw2(vlan)#vtp client
Setting device to VTP CLIENT mode.
sw2(vlan)#vtp domain cisco
Changing VTP domain name from NULL to cisco
sw2(vlan)#vtp password cisco
Setting device VLAN database password to cisco.
sw2(vlan)#exit
