NA-NP-IE系列实验46:VTP 配置

[align=left]实验46:VTP 配置[/align]
[align=left]1. 实验目的[/align]
[align=left]通过本实验，读者可以掌握如下技能：[/align]
[align=left]（1） 理解VTP 的三种模式[/align]
[align=left]（2） 熟悉VTP 的配置[/align]
[align=left]2. 实验拓扑[/align]
[align=left]拓扑图[/align]



[align=left]3. 实验步骤[/align]

注：
[align=left]1.VTP 修剪和VTP 版本只需要在一个VTP server 进行即可，其他server 或者client[/align]
[align=left]会自动跟着更改。VTP 修剪是为了防止不必要的流量从trunk 链路上通过，通常需要启用。[/align]
[align=left]2.有的IOS 版本可以在全局模式下配置vlan，我用的这个只支持在vlan database 下配置vlan。[/align]
[align=left]3. 把三台交换机的配置清除干净，重启交换机[/align]
[align=left]delete flash:vlan.dat[/align]
[align=left]erase startup-config[/align]
[align=left]reload[/align]
[align=left]sw1:server[/align]
[align=left]sw2:client[/align]
[align=left]sw3;transparent[/align]
[align=left] [/align]

[align=left]sw1(vlan)#vtp ser//以上配置S1 为VTP server，实际上这是默认值[/align]

Device mode already VTP SERVER.
[align=left]sw1(vlan)#vtp domain cisco//以上配置VTP 域名[/align]

Changing VTP domain name from NULL to cisco
sw1(vlan)#vtp password cisco//以上配置VTP 的密码，目的是为了安全，防止不明身份的交换机加入到域中
Setting device VLAN database password to cisco.
