show flash

This command displays the the contents of the Flash file system. Flash file systems differ between Catalyst
supervisors. Some supervisors use the show flash command to display the contents, while others use the dir
bootflash: command. When you copy an image to the SupIIIG, for example, you use the download command
and the Flash is completely erased in the process of installing the image. With other sups, you can use the
copy tftp flash command in order to add one or more images.
Many problems, both hardware and software related, can be avoided if you understand the Flash system for
your supervisor.
Refer to the show flash or dir bootflash: command for more information.
