1、精选优质文档-倾情为你奉上第十一章 VLAN11.1 配置VLANs and VTP 1.这节实验主要用到的命令vlan database vlan ID name *vtp password *vtp domain *vtp pruning vtp mode *switchport trunk encapsulation *switchport mode *switchport access vlan IDencapsulation dot1Q VLAN ID 2.命令的定义vlan database ：进入VLAN的配置模式下配置vlan ID name * ：创建新的VLAN，并可以对创
2、建的VLAN进行命名vtp password * ：VTP的验证密码配置vtp domain * ：VTP的域名设置vtp pruning ：VTP的裁剪vtp mode *：VTP的模式switchport trunk encapsulation *：对交换机接口进行干道的封装switchport mode *：交换机的接口模式switchport access vlan ID ：把交换机的接口加入到VLAN中encapsulation dot1Q VLAN ID ：对路由期子接口封装，加入VLAN3.所需设备下面是做这个实验练习所需的设备：1) 一台Cisco 路由器都具有一个以太网接口；
3、2) 两台Cisco交换机24接口；3) Cisco 10.0版或更高；4) 三台运行了终端仿真程序的PC可以连接到交换机端口；4.实验步骤：掌握VTP配置方法，掌握VLAN间路由配置方法以及子接口的配置。通过这个综合的实验了解完整的交换常用的各种模式的配置。 实验的拓扑如下图，IP地址在图中都有注明：1. 交换机SW1SW1(config)#interface fastEthernet 1/1SW1(config-if)#switchport trunk encapsulation dot1q SW1(config-if)#switchport mode trunk SW1(config-i
