    I have a number of 2960s that I have inherited and there is no documentation on the setup and NO passwords. I need to change setting so I can deploy WDS images which is not presently possible with the present switch configurations. By resetting I can hopefully accomplish this AND create documentation so the next idiot who takes over these sites doesn’t go through the same hell as me.

    I have found the following instructions and need to know if these will take the switches back to Factory Defaults and allow me to run an Express Setup feature. I am a Cisco nuffy and know diddly squat about Cisco CLI so I request some confirmation on the validity of the below instructions I found at http://internationalmanofawesome.wordpress.com/2010/09/13/resetting-a-cisco-2960g-switch-back-to-factory-defaults-if-you-dont-know-the-passwords/

    Code:

    Thanks.
