交换技术之 交换机间同步Vlan配置信息 VTP
1.目的：
解决多个交换机之间Vlan配置信息的同步（不包括哪些接口属于哪个vlan ，这个猜需要到具体的交换机上对端口进行配置）
2.原理：
配置一个管理端 Server（所有的vlan配置都在这台交换机，配置信息会自动同步到客户端）
配置一个或多个客户端 Client（不允许创建Vlan的一些信息，只能通过同步服务器端的配置）
3.拓扑图：
4.配置命令：
VTP-SERVER(config)#vtp domain frogtwo
VTP-SERVER(config)#vtp mode server [ client ]
VTP-SERVER(config)#vtp version 2
5.配置步骤：
S1作为服务器端配置
