一、实验目的

通过本实验，可以掌握以下技能：

配置接口IP地址。
配置路由器主机名。

二、设备需求

Cisco路由器1台，
1台带有超级终端程序的PC机，以及Console电缆及转接器。

三、拓扑结构及接口IP配置

1. 设置主机名、描述、IP地址和始终速率

进入特权模式，使用hostname命令来修改主机名，使用console线连接路由器和pc机

拓扑结构为：

拓扑结构1

使用banner命令来设置一个网络管理员可以看到的标志区。

拓扑结构和拓扑结构1一样。

使用ip address命令可以为一个接口添加IP地址。

拓扑结构如下：

拓扑结构2

接口及IP地址

使用description命令为一个接口添加标识

拓扑结构及实验结果如下：

拓扑结构3及实验结果

当模拟一个DCE的WAN链接时，可以为一个串行链路添加带宽和时钟速率

拓扑结构如下：

拓扑结构4
