实验目的：

l  学习如何登录到Cisco设备的Console口

实验说明：

Console口是最直接配置Cisco设备的接口，密码恢复，路由器挂机还原都必须使用此端口

实验步骤：

1.将PC的串行接口（COM通讯端口）和路由器的CONSOLE端口通过反转电缆（Roll-over Cable ）连接

2.在PC上，开始-所有程序-附件-通讯-超级终端 

3.点击 “确定”后,开始新连接向导

4.输入名称点击 “确定”

5.选择对应的com端口,并点击 “确定”

6.点击 “还原为默认值”，将“端口设置”参数还原为默认值即可进入到cisco设备的console配置界面

7.打开路由器电源开关，观察路由器启动过程。若路由器此时已经启动，show version查看并填写路由器以下参数:

路由器型号:              

路由器内存:                 

IOS版本号:              

接口类型和数目:                  

FLASH容量:              

NVRAM容量:

注：1） 此方法用于连接较少数量的设备

2） 新设备配置通常使用此方法

3） 建议使用Scrt软件做为Console口控制端软件，功能比微软自带的超级终端强很多
