Chapter 1: AT-CV5M02 Management Card

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 the 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 “Save” command needed to perform this
operation. 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. These 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 whenever you change the operating modes of
these line cards through the AT-CV5M02 Management Card.
AT-CV5M02
Management
Card
The AT-CV5M02 Management Card has four configuration files. Two of
the files are referred to as the master configuration files and the other two
as the SNMPv3 configuration files. Most of the following sections discuss
the master configuration files. To learn about the SNMPv3 configuration
files, refer to “SNMPv3 Configuration Files” on page 37.
The master configuration files contain most of the settings of the
management card itself. For example, stored in these files are the card’s
IP address, the syslog server address, and the settings of its 10/100Base-
TX port.
The master configuration files also contain the settings of all of the
AT-CM2, AT-CM3, and AT-CM70S Line Cards in the chassis. This
includes their operating modes, their port settings, and the OAM settings.
The reason the configurations of the line cards are stored here as well as
on the cards themselves is so that you can restore them to the cards,
should that be necessary, such as if you replace a card.
The two master configuration files differ in where they are stored and how
they are updated. One of the master configuration files is stored in DRAM.
The management card updates this file automatically when you change a
parameter on the management card or on a line card. It does this by
