你還在為不知道Cisco 3750交換機密碼初始化教程而煩惱么?接下來是小編為大家收集的Cisco 3750交換機密碼初始化教程教程，希望能幫到大家。
Cisco 3750交換機密碼初始化教程
1. 連接交換機的console口到終端或PC仿真終端。用無Modem的直連線連接PC的串行口到交換機的console口。
2. 拔掉交換機的電源.
3. 按住交換機上的Mode按鈕,與此同時,重新插上交換機的電源線.當交換機上SYST的LED長期亮的時候，可以松開Mode按鈕。

[1] Return back to the setup without saving this config.
[2] Save this configuration to nvram and exit.
這里有一個有趣的地方，那就是你能夠選擇進入命令行接口模式并放棄剛才的配置(0)，你也能夠回頭重新再設置一遍(1)，也能夠保存配置到NVRAM中并退出重啟(2)。這里我選擇的是0，我們將不保存剛才的配置并進入命令行接口模式(CLI)。接下來我們將介紹CLI。再重復一次，你可以在任何時候按下 Ctrl+C來退出安裝模式。
Enter your selection [2]: 2
