Saving Your Configuration Changes
As you configure the parameter settings on the AT-CV5M02 Management
Card and the AT-CM2, AT-CM3, and AT-CM70S Line Cards, it’s important
to keep in mind how the cards go about the task of permanently saving
their settings. Otherwise, you may find yourself having to reenter the same
settings if you have to reset a card or a chassis. You’ll also miss out on an
important feature of the Converteon product line that lets you restore
previous configurations to the line cards.
There are two parts to this discussion. The first has to do with the
commands that you use in the menus and the web browser windows to
save the configuration settings. This part of the discussion is the focus of
the following subsections. As you’ll learn, all of these commands do
basically the same thing, which is they update the master configuration file
in flash memory on the management card. Where they differ is in the
amount of information that’s saved. There are commands for saving just
the changes to the management card, the changes to a single line card, or
the changes to all of the line cards in the chassis.
The second part of the discussion has to do with the configuration files
themselves. There are actually several configuration files on the
management card and a separate configuration file on each of the line
cards. This part of the discussion is explained in “Configuration Files” on
page 32.
Saving the
Configuration of
the AT-CV5M02
Management
Card
When you enter a change to a parameter setting on the management
card, your change is automatically saved by the card in a file in DRAM. For
instance, if you change the card’s IP address, adjust the speed or duplex
setting of its 10/100Base-TX port, or enter the IP address of a syslog
server, the management card automatically records the new setting in the
file. However, since this file is stored in DRAM, it’s only temporary, which
is why its referred to as the temporary master configuration file. If you turn
off the chassis or reset or remove the management card, your changes
are discarded.
If you want to permanently save your changes, which, in most cases, you
probably will, you have to instruct the management card to copy its
temporary master configuration file in DRAM to permanent storage in flash
memory. The configuration file, after stored in flash, will retain the settings
even when the card is powered off.
The command in the menus for instructing the management card to save
its configuration settings to permanent storage is in the System
Configuration Menu. The menus that lead to the command and the
command itself are:
Main Menu -> Configuration -> System Configuration -> Save System
