Hi All,
Whats the best way to erase sensitive info from Cisco 2950 switches before disposing.
1) Is it enough to delete config.text and vlan.dat from rommon (switch:) mode ?
2) Is it better to format flash: from rommon (switch:) mode ?
3) What about the NVRAM. According to my testing once format flash: is done the startup-config file in NVRAM is empty.
Thank you.

My concern about formatting flash is with deleting the image file for the switch. The original post speaks of "disposing" the switch but I am not sure what that really means. If they intend to scrap the switch then having no image file is fine and formatting flash is the most effective way to remove any sensitive information. But if they have any intention of selling the switch or of passing it on to someone else then having no image file is a problem. Perhaps the original poster can clarify what they intend to do with this switch?

Hi Richard and All,
Thanks for the replies. These switches are going to be scrapped.
There are many switches so I have written a Python script to format flash via console.

Thanks for clarifying that these switches will be scrapped. In this case I agree that format flash is the most complete way to remove any sensitive information.
