    cisco catalyst 2960 password recovery

    To reset your Cisco 2960 password, connect your console cable to the switch and open up your terminal emulator software, you can use minicom if you are using Linux. Please visit this link on how to install and configure minicom using in Fedora/Red Hat/CentOS and this link if you are using Debian/Ubuntu.
    Power on the switch while holding the mode button. Release the mode button after you see the screen below in your terminal emulator software.
    Boot Sector Filesystem (bs) installed, fsid: 2       
    Base ethernet MAC Address: 1c:1d:86:db:c8:80         
    Xmodem file system is available.
    The password-recovery mechanism is enabled.
    The system has been interrupted prior to initializing the
    flash filesystem.  The following commands will initialize
    the flash filesystem, and finish loading the operating 
    system software:
    Initialize the flash file system using the below command.

    Find the config file in flash: directory
    dir flash:
    The files that we are looking for in the flash: directory is the config.text file.
    Directory of flash:/

    Rename the config file so that it will not be loaded when we boot to the switch.
    rename flash:config.text flash:config.text.old
    Then type the below command to boot to the switch
    After booting, the switch will ask you to enter the "initial configuration dialog" to initially configure the switch using interactive CLI mode. Just type the word "no" because we are not re-configuring the switch.
             --- System Configuration Dialog ---
    Enable secret warning
    In order to access the device manager, an enable secret is required
    If you enter the initial configuration dialog, you will be prompted for the enable secret
    If you choose not to enter the intial configuration dialog, or if you exit setup without setting the enable secret,
    please set an enable secret using the following CLI in configuration mode-
    enable secret 0 
    Would you like to enter the initial configuration dialog? [yes/no]: no
    At the switch prompt type en to enter enable mode.
    Rename the configuration file to its original filename.
    rename flash:config.text.old flash:config.text
    Copy the configuration file into the memory
    copy flash:config.text system:running-config
    Now that the config is loaded in to the memory, we can start changing the password.
    conf t
    enable secret newpassword
    After changing the password, save the config and done.
    write memory
    This tutorial will also work on Cisco 2950 switches. Hope this helps.
