traditional network design. As an example, with VLANs you can segment

Configuration Save
and Restore
The Configuration Save and Restore feature allows the configuration of
your Switch to be saved as a file on a remote server, or to be restored
onto the Switch from a remote file. The configuration information is
stored in an editable ASCII text file as a set of Command Line Interface
(CLI) commands.
All configuration information that can be set using the Switch’s
Command Line Interface is saved and restored. Sensitive information such
as user passwords and the IP address configuration
is not saved. You can
edit the text file and add this information if you wish before restoring the
configuration.
If the Switch is part of a stack, it is the configuration of the stack that is
saved and restored. You cannot restore the configuration of a single unit
in the stack from the saved file; you must restore the configuration of the
entire stack.
You must have either the manager or security management access level
to be able to save and restore the Switch configuration. If a manager level
user attempts to restore a configuration that was saved by a security level
user, the restore operation will fail because the security level commands
are not available to the manager. A manager level user can only save a
configuration that contains the commands that are available to that user
level.
Important Considerations
■
The Switch unit must be reset to its factory default settings before you
can restore a configuration onto it. You can reset the Switch using the
protocol ip initializeConfig
CLI command or the System >
Control > Initialize Web interface operation.
