Recovering from a Lost or Forgotten Password Follow the steps in this procedure if you have forgotten or lost the switch password.
Step 1 Connect a terminal or PC with terminal emulation software to the console port. For more information, refer to the switch installation guide.

Note You can configure your switch for Telnet by following the procedure in the "Accessing the CLI" section.
Step 2 Set the line speed on the emulation software to 9600 baud.
Step 3 Unplug the switch power cord.
Step 4 Press the Mode button, and at the same time, reconnect the power cord to the switch.
You can release the Mode button a second or two after the LED above port 1X goes off. Several lines of information about the software appear, as do instructions:
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 5 Initialize the Flash file system:
switch: flash_init


Step 6 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 7 Load any helper files:
switch: load_helper


Step 8 Display the contents of Flash memory:
switch: 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)


Step 9 Rename the configuration file to config.text.old.
This file contains the password definition.
switch: rename flash:config.text flash:config.text.old


Step 10 Boot 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 11 At the switch prompt, change to privileged EXEC mode:
switch> enable


Step 12 Rename the configuration file to its original name:
switch# rename flash:config.text.old flash:config.text


Step 13 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 use these normal commands to change the password.
Step 14 Enter global configuration mode:
switch# config terminal


Step 15 Change the password:
switch(config)# enable secret <password>


or
switch(config)# enable password <password>


Step 16 Return to privileged EXEC mode:
switch(config)# exit switch#


Step 17 Write the running configuration to the startup configuration file:
switch# copy running-config startup-config


The new password is now included in the startup configuration.
