Chapter 8: Configuration File Commands
130
Overview
The management and media converter modules store their parameter
settings in a series of files called configuration files. These files enable the
modules to retain their parameter settings even when they are moved to a
different slot or chassis or when the chassis is reset or power cycled. This
saves you from having to reconfigure the parameter settings when you
power cycle a chassis or move a module.
The modules do not automatically update their configuration files when
you change a parameter setting. Rather, you must initiate the update with
this command:
config save
When you issue this command, all the modules in the chassis or stack
update their configuration files to match their current operating
parameters.
The management module has in its file system the master configuration
file. This file contains the parameter settings for all the modules in a
chassis and is used by the management module to configure the settings
of the modules whenever you reset or power cycle a chassis.
The media converter modules have auxiliary configuration files that store
their individual configuration settings. These files are primary used to build
the master configuration file on the management module. But these files
also enable the modules to retain their settings when they are moved to a
different slot in a chassis or to an entirely different chassis.
The management and media converter modules come with predefined
auxiliary configuration files, but there is no predefined master
configuration file on the management module. You must create it as part
of the initial configuration procedure of the chassis. For instructions, refer
to “Creating a Master Configuration File” on page 28.
When you issue the CONFIG SAVE command to save your parameter
changes, the management module updates the master configuration file
using the auxiliary configuration files from the media converter modules.
Here is an outline of the process:
1. When the CONFIG SAVE command is issued, all the modules in the
chassis or stack update their auxiliary configuration files to reflect their
current parameter settings. The filenames are “BM.CFG” for a media
converter’s file and “MM.CFG” for the management module’s file.
These file naming conventions cannot be changed.
