    Recovering from Lost or Forgotten Passwords on Non-LRE Catalyst 2950 Switches

    Follow these steps if you have forgotten or lost the switch password on a non-LRE Catalyst 2950 switch:

    Step 1 Connect a terminal or PC with terminal emulation software to the consoleservice port. For more information, see the switch hardware installation guide.

    Note You can configure your switch for Telnet by following the procedure in the "Accessing the CLI" section on page 2-9.

    Step 2 Set the line speed on the emulation software to 9600 baud.

    Step 3 Unplug the switch power cord.

    Step 4 Reconnect the power cord to the switch and, within 15 seconds, press the Mode button while the System LED above port 1X is still flashing green. Continue pressing the Mode button until the System LED turns briefly amber and then solid green; then release the Mode button.

    Several lines of information about the software appear, as do instructions:

    The system has been interrupted prior to initializing the flash file system. These
    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 consoleservice 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 appears in the directory.

    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 the following normal commands to change the password.

    Step 14 Enter global configuration mode:

    switch# configure 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
