Cisco Systems 3560 사용자 설명서

switch: flash_init

If you had set the console port speed to anything other than 9600, it has been reset to that particular 
speed. Change the emulation software line speed to match that of the switch console port.

Load any helper files:

switch: load_helper

Start the file transfer by using the Xmodem Protocol.

switch: copy xmodem: flash:image_filename.bin

After the Xmodem request appears, use the appropriate command on the terminal-emulation software to 
start the transfer and to copy the software image into flash memory.

Boot the newly downloaded Cisco IOS image.

switch:boot flash:image_filename.bin

Use the archive download-sw privileged EXEC command to download the software image to the 
switch.

Use the reload privileged EXEC command to restart the switch and to verify that the new software 
image is operating properly.

Delete the flash:image_filename.bin file from the switch.

The default configuration for the switch allows an end user with physical access to the switch to recover 
from a lost password by interrupting the boot process during power-on and by entering a new password. 
These recovery procedures require that you have physical access to the switch.

On these switches, a system administrator can disable some of the functionality of this feature by 
allowing an end user to reset a password only by agreeing to return to the default configuration. If you 
are an end user trying to reset a password when password recovery has been disabled, a status message 
shows this during the recovery process.

These sections describes how to recover a forgotten or lost switch password:

You enable or disable password recovery by using the service password-recovery global configuration 
command. Follow the steps in this procedure if you have forgotten or lost the switch password. 

Connect a terminal or PC with terminal-emulation software to the switch console port.

Set the line speed on the emulation software to 9600 baud.

Power off the switch.
