How do I recover a password on a Catalyst 3524?

Customer forgot his password on a Cat3524...need to know how to get back into the box.


Re: How do I recover a password on a Catalyst 3524?

Attach a terminal or PC with terminal emulation (for example, Hyper Terminal) to the console port of the switch. Use the following terminal settings:

9600 baud rate

No parity

8 data bits

1 stop bit

No flow control

Unplug the power cable.

Hold down the mode button located on the left side of the front panel, while reconnecting the power cord to the switch. You can release the mode button a second or two after the LED above port 1x is no longer illuminated.

The following instructions appear:

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:




Type flash_init.

Type load_helper.

Type dir flash:.

!--- Make sure to type a colon ":" after the dir flash

The switch file system is displayed:

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)

Type rename flash:config.text flash:config.old to rename the configuration file.

This file contains the password definition.

Type boot to boot the system.

Enter N at the prompt to start the Setup program, Continue with the configuration dialog? [yes/no] : N

At the switch prompt type en to turn on enable mode.

Type rename flash:config.old flash:config.text to rename the configuration file with its original name.

Copy the configuration file into memory:

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

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

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

The configuration file is now reloaded.

Change the password:

switch#configure terminal

switch(config)#no enable secret

!-- This step is necessary if the switch had an enable secret password

switch(config)#enable password Cisco



Write the running configuration to the configuration file:

switch#write memory
