Managing CMM Directory Content
CMM Files
The management of a switch is controlled by three types of files:
•
Image files, which are proprietary code developed by Alcatel-Lucent. These files are not configurable
by the user, but may be upgraded from one release to the next. These files are also known as archive
files as they are really the repository of several smaller files grouped together under a common head-
ing.
Available Files
This table lists the image and configuration files for the OmniSwitch. Most of the files listed here are part
of the base switch configuration. Files that support an optional switch feature are noted in the table.
File Name
Reni.img
Ros.img
Rrescue.img
boot.cfg
•
A configuration file, named boot.cfg, which is an ASCII-based text file, sets and controls the config-
urable functions inherent in the image files provided with the switch. This file can be modified by the
user. When the switch boots, it looks for the file called boot.cfg. It uses this file to set various switch
parameters defined by the image files.
Modifications to the switch parameters affect or change the configuration file. The image files are static
for the purposes of running the switch (though they can be updated and revised with future releases or
enhancements). Image and configuration files are stored in the Flash memory (which is equivalent to a
hard drive memory) in specified directories. When the switch is running, it loads the image and configura-
tion files from the Flash memory into the RAM. When changes are made to the configuration file, the
changes are first stored in the RAM. The procedures for saving these changes via the CLI are detailed in
the sections to follow.
CMM Software Directory Structure
The directory structure that stores the image and configuration files is divided into multiple parts:
•
The certified directory contains files that have been certified by an authorized user as the default files
for the switch. Should the switch reboot, it would reload the files in the certified directory to reactivate
its functionality. Configuration changes CAN NOT be saved directly to the certified directory.
•
The working directory contains files that may or may not be altered from the certified directory. The
working directory is a holding place for new files. Files in the working directory must be tested before
committing them to the certified directory. You can save configuration changes to the working direc-
tory.
•
User-defined directories are any other directories created by the user. These directories are similar to
the working directory in that they can contain image and configuration files. These directories can have
any name and can be used to store additional switch configurations. Configuration changes CAN be
saved directly to any user-defined directory.
