Configuration Files
The management card and the media converter line cards store their
parameter settings in a series of configuration files. These files enable the
cards to retain their settings even when they are removed from the chassis
or when the chassis is powered off.
AT-CM Line
Cards
The parameter settings of the AT-CM Line Cards are stored in the
configuration files in flash memory on the cards. The files contain the
operating modes, the port settings, the ingress and egress filters, and the
OAM client settings of the line cards.
The cards automatically update their configuration files when you change
a parameter setting. There is no command that you have to perform. For
example, if you adjust the OAM settings on a line card, the card
automatically updates its configuration file so that it retains the new
settings even if you immediately afterwards remove the card and install it
in another slot or chassis.
AT-CV Line
Cards
The configuration files on the AT-CV Line Cards operate the same as the
files on the AT-CM Line Cards. The AT-CV Line Cards, however, have
only one adjustable parameter, the operating mode. So their configuration
files contain just that one parameter. These configuration files are also
automatically updated when you change the operating modes of these line
cards through a management card.
AT-CV5M02
Management
Card
The AT-CV5M02 Management Card has two master configuration files.
These files contain the settings of the management card and all of the line
cards in the chassis. The management card stores one of the master
configuration files in DRAM and automatically updates it by constantly
polling the line cards over the backplane in the chassis for their current
parameter settings. This file is temporary because it is discarded
whenever the chassis is powered off or the management card is reset or
removed from the chassis.
The second master configuration file on the AT-CV5M02 Management
Card is stored in flash memory and so is retained even when the chassis is
powered off. This master configuration file, however, is not updated
automatically. Instead, you have to instruct the management card to do it
by issuing one of the save commands. When you enter a save command,
the management card copies the master configuration file in DRAM to
flash memory for permanent storage. For information on the save
commands, refer to “Saving Your Configuration Changes” on page 64.
Here are the steps that the management card and the line cards perform
when one of their parameter settings is changed.
