Managing System Files
This chapter describes how to work with the Controller File System (CFS), which
provides a single interface for managing all files available for use with Meru control-
lers. This chapter contains the following sections:
 About the CFS
 Working with Configuration Files
 Manipulating System Files

About the CFS
The CFS allows you to manage the controller operating system (System Director) and
its configuration files.
Files used to operate the controller are located in directories on the controller flash
card. Initially, the flash contains the shipped operating system, referred to as the
image, which of course is set with default settings. During the course of normal oper-
ation, you probably will want to perform some or all of the following tasks:
 Configure custom settings and save the settings to a configuration file.
 Save the configuration file to a backup directory on the controller.
 Save the configuration file to a remote location to provide a more secure backup
or as input for configuring other controllers.
 Restore the settings from a known, reliable backup file.
 Restore the system to its default settings.
 Upgrade the system to a new version of the operating system.
 Downgrade the system to a previous operating system version.
 Execute scripts to automate configuration.
