Recovering from a Lost or Forgotten Password
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 switch_image
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.
Step 9 Copy the configuration file into memory:
Switch# copy flash:config.text system:running-config
Source filename [config.text]?
Destination filename [running-config]?
Press Return in response to the confirmation prompts.
The configuration file is now reloaded, and you can change the password.
Step 10 Enter global configuration mode:
Switch# configure terminal
