恢复出厂教程

使用终端软件进行连接

  1. 电脑COM口，通过console线连接到交换机console口，并打开超级终端调试窗口，我这里使用MobaXterm演示。

  2. 打开MobaXterm，点击Session。

  3. 选择Serial，再选择对应的COM口，波特率选择9600，点击ok。

  4. 刚进入是黑屏的，敲一下Enter键就会出来显示画面。

  5. 交换机接上电，上电过程中，按住交换机正面"MODE"按钮，直到syst灯快速闪烁。

    松开"MODE"按钮（也可以关注终端界面显示字符了就可以松开"mode"按钮），进入到交换机的底层模式switch:

重置为出厂默认设置，而 VLAN 信息除外。

  1. 进入特权模式

    enable

  2. 输入命令进行清除，按Enter键进行确认。

    write erase

  3. 输入重启命令，然后按Enter键/y确认加载。

    reload

  4. 交换机将自动重启，稍等片刻就会重新显示连接画面。

  5. Cisco官方教程（和实际的略有不同）

    重置交换机配置
要将交换机重置为出厂默认设置，请发出e rase startup-config  或 write erase   命令。此命令不会清除引导变量，例如 config-register 和引导系统设置。

可以使用 boot 命令修改引导系统参数。在运行Cisco IOS软件的Catalyst 4500/4000和6500/6000系列交换机中，您可以将 config-register   命令。

本示例显示如何使用CLI将运行Cisco IOS软件的交换机重置为出厂默认设置 write erase 指令：

Cat2950# write erase
Erasing the nvram filesystem will remove all files! Continue? [confirm]y[OK]
Erase of nvram: complete
Cat2950#
Cat2950# reload

System configuration has been modified. Save? [yes/no]: n    

!--- Do not save the configuration at this prompt. Otherwise, the switch !--- reloads with the current running configuration and does not reset to default. 

Proceed with reload? [confirm]y

此时交换机配置已重置为出厂默认设置，而 VLAN 信息除外。

清除所有配置

  1. 同样和前面一样使用终端进行连接，并进去特权模式。

    enable

  2. 清除启动配置信息

    erase startup-config

    下面的提示按Enter键进行确认

  3. 删除vlan配置信息

    delete flash:vlan.dat

    下面的两个提示按Enter键进行确认

  4. 输入重启命令

    reload

    提示是否继续重新加载，按Enter键进行确认。

  5. 交换机将自动重启，并自动显示连接画面。

  6. 显示当前配置
