思科设备交换机vtp学习功能配置.docx

本次讲解交换机vtp的vlan学习功能（相对于上一期各交换机vlan配置，使用中继线相连的交换机都需要进行相应的配置。如果更改 VLAN，所有的相关交换机也要做变更，这样工作就太大了。采用VTP (VLAN Trunking Protocol)协议可以简化配置工作。VTP有三种工作模式：服务器模式、客户端模式和透明(transparent)模式，默认是服务器模式。 服务器模式的交换机可以设置VLAN配置参数，服务器会将配置参数发给其他交换机。客户端模式的交换机不能设置VLAN配置参数，只能接受服务器模式的交换机发送的VLAN配置参数。透明模式的交换机是相对独立的，它允许设置VLAN配置参数，但不向其他交换机发送自己的配置参数。当透明模式的交换机收到服务器模式的交换机 发送的VLAN配置参数时，仅仅是简单地转发给其他交换机，并不用来设置自己的VLAN参数。当交换机处于VTP服务器模式时，如果删除一个VLAN，则该VLAN将在所有相同VTP的交换机上被删除。当在透明模式下删除时，只在当前交换机上被删除）本例配置模型图命令行：SwitchA配置如下：SwitchenableSwitch#vlan database /进入vlan配置模式% Warning: It is recommended to configure VLAN from config mode, as VLAN database mode is being deprecated.
