Working with the Flash File System
The flash file system is a single flash device on which you can store files. It also provides several
commands to help you manage software image and configuration files. The default flash file system on
the switch is named flash:.
As viewed from the stack master, or any stack member, flash: refers to the local flash device, which is
the device attached to the same switch on which the file system is being viewed. In a switch stack, each
of the flash devices from the various stack members can be viewed from the stack master. The names of
these flash file systems include the corresponding switch member numbers. For example, flash3:, as
viewed from the stack master, refers to the same file system as does flash: on stack member 3. Use the
show file systems privileged EXEC command to list all file systems, including the flash file systems in
the switch stack.
No more than one user at a time can manage the software images and configuration files for a switch
stack.
