Chapter 45 Troubleshooting

Recovering from a Lost or Forgotten Password

Procedure with Password Recovery Enabled

If the password-recovery mechanism is enabled, this message appears:

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

Step 1 Initialize the flash file system:

switch: flash_init

Step 2 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. Step 3 Load any helper files:

switch: load_helper

Step 4	Display the contents of flash memory:
	switch: dir flash:
	The switch file system appears:
	Directory of flash:
	13	drwx	192	Mar 01	1993	22:30:48	c3750e-universal-mz.122-35.SE2
	11	-rwx	5825	Mar 01	1993	22:31:59	config.text
	18	-rwx	720	Mar 01	1993	02:21:30	vlan.dat

16128000 bytes total (10003456 bytes free)

Step 5 Rename the configuration file to config.text.old.

This file contains the password definition.

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

Step 6 Boot up the system:

switch: boot

You are prompted to start the setup program. Enter N at the prompt:

Continue with the configuration dialog? [yes/no]: N

Step 7 At the switch prompt, enter privileged EXEC mode:

Switch> enable

Step 8 Rename the configuration file to its original name:

Switch# rename flash:config.text.old flash:config.text

Note Before continuing to Step 9, power on any connected stack members and wait until they have completely initialized. Failure to follow this step can result in a lost configuration depending on how your switch is set up.
