Managing CMM Directory Content

CMM Files

The management of a stack or single switch is controlled by three types of files:
• Image files, which are proprietary code developed by Alcatel-Lucent to run the hardware. These files
are not configurable by the user, but can 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 under a
common heading.
• 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.
• A boot file on the OmniSwitch, named boot.slot.cfg, is an ASCII-based text file that numbers the
switches in a stack. A boot file on the OmniSwitch, named boot.params, is an ASCII-based text file
that sets the Ethernet Management Port (EMP) IP address, gateway, and mask. It also controls the baud
rate of the console port and displays directory loading information and is located in the Flash memory
of the switch.
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 through 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 two parts:
• The certified directory contains files that have been certified by an authorized user as the default files
for the switch. If the switch reboots, it would reload the files in the certified directory to reactivate its
functionality.
• The working directory contains files that can or cannot 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. You can reboot the switch from the working directory by using the reload working command as
described in "Rebooting from the Working Directory" on page
The running configuration is the current operating parameters of the switch obtained from information
from the image and configuration files. The running configuration is in the RAM.
