settings of the modules when a unit is power cycled or reset. Without the
files, you would have to reconfigure the modules whenever you reset a
device.
The modules do not automatically update their configuration files and the
active master configuration file when you change a device’s parameter,
such as the speed of a port on a media converter module. Instead, you
must initiate the update with the CONFIG SAVE command. This command
instructs all the modules in a chassis, or stack, to update their
configuration files to match their current settings. You should always
perform this command after adjusting the parameter settings of the
modules. Otherwise, your changes are discarded when you reset or power
cycle the unit.
Note
Many of the chapters in this guide have a note on the first page
reminding you to update the configuration files with the CONFIG
SAVE command after entering your parameter changes.
For further information on configuration files and the CONFIG SAVE
command, refer to Chapter 9, “Configuration File Commands” on page
141.
Setting Chassis
ID Numbers
Commands that configure or display the parameters on a media converter
module must include a chassis ID number. This parameter identifies the
chassis with the media converter module. For example, to configure a port
on a media converter module with the SYSTEM SET PORT command,
you must include in the command the chassis ID of the unit with the
module. See Figure 1.
