实验总结 ：
VTP 版本一致
VTP 域名定义
VLAN 创建
观察VTP修订版本号和VTP数目变化
VTP三种模式 ：
修改VTP工作模式会导致VTP修订版本号置0 但VLAN数据不会丢失
VTP工作过程中VLAN传输原理与规则 ：
从高版本号的交换机想低版本号的交换机传输 （VTP工作模式为Server/Client）
VTP透明模式在工作过程中版本号和VLAN不发生改变 可创建和修改VLAN
可以提供透明转发其他网络交换机VLAN数据的功能
VTP Server模式在工作过程中版本号会随VLAN的创建修改和VTP模式变换而发生改变
VTP Client模式在工作过程中版本号会随其他交换机的同步数据而发生改变
VLAN由其他交换机传递而创建在本地数据库 此模式并不允许手动创建和修改VLAN数据
