    Cisco 2950 Switch — IOS Error Message

    Locked

    by fm21496 ·

    I get the following IOS error messages – from my Cisco 2950 switch – when I try to backup the IOS file to my TFTP server:

    %Error parsing filename (Bad file number)

    %Error opening flash: file_name (no such file or directory)

    Has anyone come across this problem before? Your help is greatly appreciated.

      Check the Running Configuration

      Look for the following, where BootFilename is replaced by the real boot file name:

      boot-start-marker
      boot system flash:.bin
      boot-end-marker

      Either remove the line completely or put the correct file name of the file located in the flash.
