1、南昌航空大学实验报告课程名称：计算机网络 实验名称： 实验五 配置VLAN 班 级： 070613 学生姓名： 严斌 学号： 07061324 指导教师评定： 签 名： 一、 实验目的1. 配置VLAN2. 通过VLAN Trunk配置跨交换机的VLAN3. 配置VTP4. 查看上述配置项目的有关信息二、 设备需求 本实验需要以下设备：1. Cisco Catalyst 2950 系列交换机2台，型号不限；2. 交叉线序网线1条；3. 1台带有超级终端程序的PC机，以及Console电缆及转换器。三、 拓扑结构及配置说明图 8-1 网络拓扑图如图所示用交叉网线把C2950A的FastEther

2、net0/24端和C2950B的FastEthernet0/24端口连接起来。四、 实验步骤及要求1. 在2950系列交换机上配置VTP和VLAN的方法有两种，本实验演示的是使用vlandatabase命令的一种;另一种是在全局配置模式下发出配置命令，格式与vlan database方式相似。方法如下：1) vlan vlan-id 输入一个VLAN号, 然后进入vlan配置状态，可以输入一个新的VLAN号或旧的来进行修改。2) name vlan-name (可选)输入一个VLAN名，如果没有配置VLAN名，缺省的名字是VLAN号前面用0填满的4位数，如VLAN0004是VLAN4的缺省名字

3、.2. 首先使用vlan database命令进入VLAN配置模式。在VLAN配置模式下，可以设置VTP的一系列属性，如vtp?命令所示，也可以对VLAN进行定义。3. 把C2950A交换机设置成VTP Server模式(缺省配置)，VTP域名为Test。4. 定义V10、V11、V12和V13等4个VLAN。5. show vtp status命令显示了VTP相关的配置和状态信息，我们应主要关注VTP模式、域名，VLAN数量等信息。6. show vtp counters命令列出了VTP的统计信息，表明各种VTP相关包的收发情况，因为C2950A交换机与C2950B交换机没有进行VTP信息的

4、传输，所以各项数值均为0。7. 在接口配置模式下的switchport mode access命令设置对应端口为静态VLAN访问模式。8. 在接口配置模式下的switchport access vlan命令把端口分配给相应的VLAN。9. 在第2段中，配置了C2950B交换机的VTP属性，域名设为Test，模式为Client。10. 第3段设置了C2950A和C2950B之间的VLAN Trunk。所使用的命令是在接口配置模式下发出switchport mode trunk。当然这是命令的一种形式，设置Trunk还有其他可选的命令形式。11. show interface fa0/24 swi

5、tchport查看了Fa0/24端口上的交换端口属性，我们关心的是几个与Trunk相关的信息。它们是:运行方式为Trunk、Trunk，封装格式为802.1Q、Trunk中允许所有VLAN传输等。12. 完成两台交换机之间的Trunk配置后，可以看到C2950B交换机上的VTP和VLAN属性已经可以从C2950A交换机自动获得。13. 最后发出的ping指令表明C2950A和C2950B之间在IP层是连通的，并且再次验证了Trunk的工作是正常的。五、 实验结果第一段 配置2950A交换机的VTP CLI session with the switch is open.
