思科八爪电缆的用法_路由器设置网

第一次接触思科的八爪电缆，是在上CCNA的时候，那个时候还不知道八爪电缆的作用，现在终于有机会见到了，开始配置一台2511 作为管理路由器，通过电脑Console路由器，然后路由器的ASYNC口分出线缆来管理其他的路由器，什么也别说了，开始我们的实验吧！

材料：2511路由器一台，八爪鱼一根，Console线一条，然后测试机器一台。

连接方法：电脑连接console管理2511，在2511的SYNC口接上八爪鱼，然后就做以下的配置（嫌麻烦的童鞋可以直接拷贝代码，修改一下地址和名字就可以直接用了。

ip host zyw16 2016 192.168.100.200
ip host zyw17 2017 192.168.100.200

ip host第一个命令把终端服务其的第一条异步线路和一个叫做zyw1的主机名进行了关联，以后只要在终端服务器中输入 zyw1，就可以把配置界面切换到叫做zyw1的那一台设备上进行调试，前提是zyw1这台设备必须连接在终端服务器的异步接口1上的第一条线路。

以下是我的2511配置信息：

Tserver#sho run

最后测试的结果是：

（Tserver是我的2511）

Tserver#zyw1
Trying zyw1 (192.168.100.200, 2001)... Open
Router>（这一台是测试路由）

进入测试路由器后要从测试路由器退出的话就要按快捷键 CTRL+Shift+X 然后按6 就退出2511的管理界面。另外要注意的是：如果出现远端拒绝的信息的话就先要检查线路是否接上，还有线路号是否对上，物理都没有问题的话就要清线路了。

清除线路的命令:

Tserver#clear line 1
[confirm]
[OK]

下面是看线路有没有被占用的命令:
