Cisco交换机密码初始化
1.连接交换机的console口到终端或PC仿真终端。用无Modem的直连线连接PC的串行口到交换机的console口。2.拔掉交换机的电源.
3.按住交换机上的Mode按钮,与此同时,重新插上交换机的电源线.当交换机上SYST的LED长期亮的时候，可以松开Mode按钮。
4.再通过超级终端连接交换机。
5.交换机有如下显示：

Go to the IOS command prompt without saving this config.
Return back to the setup without saving this config.
Save this configuration to nvram and exit.
这里有一个有趣的地方，那就是你能够选择进入命令行接口模式并放弃刚才的配置（0），你也能够回头重新再设置一遍（1），也能够保存配置到NVRAM中并退出重启（2）。这里我选择的是0，我们将不保存刚才的配置并进入命令行接口模式（CLI）。接下来我们将介绍CLI。再重复一次，你可以在任何时候按下 Ctrl+C来退出安装模式。
Enter your selection : 2
