2. After the line card initializes its software, it queries for a management
card over the backplane of the chassis.
3. If the chassis does not have a management card, the line card
configures its operating parameters using the settings in its
configuration file in flash memory.
4. If the chassis has a management card, the following occurs:
a. The management card examines its master configuration file for
the auto-copy setting for the line card’s slot.
b. If auto-copy for the slot is enabled, the management card copies
the settings of the line card for that slot from its master
configuration file and sends them to the line card over the
backplane. When the line card receives the settings, it examines
them to determine whether or not they are from the same line card
model. If they are, it implements the settings. If they are not, it uses
the settings in its own configuration file in flash memory to
configure its parameters.
c. If auto-copy for the slot is disabled, the line card uses the settings
in its own configuration file in flash memory to configure its
operating parameters.
The setting for the auto-copy parameter is stored in the master
configuration file on the management card. It is not stored in the
configuration files on the line cards. Consequently, line cards do not carry
this setting with them when they are moved to different slots or chassis.
AT-CM Line
Cards and
Remote Peer
Management
The discussions so far have concerned configuration files on local AT-CM
Line Cards that reside in the same chassis as the management card. Most
of this information, however, also applies to remote AT-CM Line Cards that
are managed through the remote peer management feature. As explained
in “Remote Peer Management” on page 46, this feature lets you manage
remote line cards through their local AT-CM Line Card counterparts.
When a local line has a remote peer connection to a remote line card, the
AT-CV5M02 Management Card stores the remote card’s configuration in
its master configuration file. You can restore a configuration back to a
remote line card just as you can to a local line card. For instance, if you
install a new line card in a remote chassis, you can download the last
saved configuration to the card from the management card to give the new
card the same configuration as the previous card in the remote chassis.
Here are two items of importance to restoring configurations to remote
AT-CM Line Cards:
ˆ There is no auto-copy for remote line cards. To restore a previous
configuration to a remote line card, you have to do it manually. The
