Chapter 8: Configuration File Commands
148
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.
2. The media converter modules transmit a copy of their updated
auxiliary configuration files to the management module through the
backplane in the chassis.
3. When the management module stores an auxiliary configuration file in
its file system, it adds the chassis ID number and the slot number of
the source module to the filename in order to distinguish between the
various files. An example is “BM_0_1.CFG.” The first number is the
chassis ID and the second is the slot number of the module. This file
naming convention cannot be changed.
4. After the management module has received the updated auxiliary
configuration files from all of the media converter modules, it forms a
new, updated master configuration file for the entire chassis or stack
by concatenating the files.
The entire process is usually completed in a of couple seconds, but it can
vary depending on the number of media converter modules in the chassis
or stack and the number of parameter settings.
Creating a New
Master
Configuration
File
There are several ways to create a new master configuration file on a
management module. One method is with the CONFIG SAVE
FILESYSTEM command. What this command does is it creates a new
master configuration file with all of the current settings of the modules in
the chassis or stack.
Here is an example of the command. It creates the new master
configuration file “mcf_ai_traffic.cfg” on a management module in a
chassis with the ID 0:
config save filesystem=system://0/m/mcf_ai_traffic.cfg
Another way to create a new master configuration file is to edit an existing
file with a text editor by uploading it from the file system on the
management module to your management workstation, editing it with a
text editor, and downloading it again to the management module. The
instructions for uploading or downloading a file to a module’s file system
are found in Chapter 9, “File System Commands” on page 169. For
information about editing the file, refer to “Editing a Master Configuration
File” on page 150.
