实验题目
1、在S3760与S2126上划分VLAN，将PC机与服务器加入到相应的VLAN 中。

S2126A划分VLAN、端口
S2126B划分VLAN、端口
S3760B划分VLAN
2、服务器直接连接在核心交换机SW3760的Fa0/1上，需要在两个端口上限制接入服务器的数量，F0/1限制为4台，超过后将关闭该端口。

3、为S3760上的VLAN接口、R1762A和R1762B上的以太网接口配置IP地址。

S3760上的VLAN配置
R1762A以太网接口配置
R1762B以太网接口配置
4、在S3760A使用具有三层特性的物理端口实现RIP路由与R1762A实现内网的互联。

5、R1762A和R1762B之间运行静态路由协议，提供园区内部网络的连通性。

6、在R1762A和R1762B之间建立PPP链路，并对PPP进行CHAP验证。

（分）
7、在一台SERVER2上配置FTP服务器，使VLAN 10中的PC能够进行文件的上传和下载。

8、在R1762A上使用网络地址转换技术，使VLAN 10内使用私有地址的主机能够访问Internet中的资源。

9、在一台SERVER3上配置Web服务器，使VLAN 10中的PC1能够进行Web 网页的浏览。

存。
