Cisco Switch Password Recovery

If you have forgotten the password of your cisco switch, you should follow the procedure for password recovery:

1- Power up the device after connecting the device with the console.

Cisco Packet Tracer console
Cisco Packet Tracer console


2-In order to start our device in recovery mode, we start by pressing the mode button at the bottom left of our switch. We need to use the Ctrl + Break or Ctrl + c key combination after the connection is established for the switches that do not have a Mode button.

switch console
switch console


3-  After that, type the following commands

switch: flash_init
switch: load_helper
switch: dir flash


flash_init, load_helper, dir flash
flash_init, load_helper, dir flash


4- Then the name of this file should be changed temporarily so that we cannot get the initial configuration when we reboot.

switch: rename flash:config.text flash:config.old
switch: boot

5- Then the switch will reboot. The name of the file is no longer the initial configuration, so the device will open without the password.

6-In the device we access without a password, we revert the file we changed back to.

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

7- Create a new password and save the configuration.

Switch# conf t
Switch (config)#enable secret password
Switch (config)#line vty 0 15
Switch (config-line)#password password
Switch (config-line)# exit
Switch#copy running-config startup-config
