1.拔掉交换机的电源线                                                       

 

2.用超级终端和控制线连到交换机,超级终端的设置是:                         

  9600 baud rate                                                 

  No parity                                                            

  8 data bits                                                       

  1 stop bit                                                         

  No flow control                                               

 

3.按住交换机前面板“mode”按钮;插上电源线, 当端口1上面的灯不亮后,放松“mode”按钮,

 

4.这时超级终端上应该显示:                                                 

  The system has been interrupted prior to initializing the flash file system.

 

  The following commands will initialize the flash file system, and finish loading

 

  the operating system software:                 

 

  flash_init                                                         

  load_helper                                                       

  boot                                                                      

 

5.输入flash_init                                                 

 

6.输入load_helper

 

7.输入dir flash:

  这时显示:

  Directory of flash:                                       

  2 -rwx 843947 Mar 01 1993 00:02:18 C2900XL-h-mz-112.8-SA

   4 drwx 3776 Mar 01 1993 01:23:24 html

  66 -rwx 130 Jan 01 1970 00:01:19 env_vars

   68 -rwx 1296 Mar 01 1993 06:55:51 config.text

 

 1728000 bytes total (456704 bytes free)

 

 

8.输入rename flash:config.text flash:config.old

9.输入boot,重新启动系统                                                

 

10.系统启动完后显示:Continue with the configuration dialog? [yes/no] : 输入N                                                                       

 

11.输入enable

 

12.进入enable模式后,输入rename flash:config.old flash:config.text

 

 

13.接着按以下步骤操作:

 

Switch# copy flash:config.text system:running-config

 

Source filename [config.text]? (press Return)

Destination filename[running-config]? (press Return)

 

14.接着按以下步骤操作:

switch#configure terminal

switch(config)#no enable secret

switch(config)#no enable password

switch(config)#exit

switch#write memory

 

这时,系统就恢复没有密码的状态了
