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 in
flash memory for the auto-copy setting for the line card’s slot.
b. If the auto-copy feature for the slot is enabled, the management
card copies the settings of the line card for that slot from its master
configuration file in flash memory 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 discards the settings and instead 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 settings for the auto-copy parameters for the slots in a chassis are
stored in the master configuration file on the management card. They are
not stored in the configuration files on the line cards. Consequently, the
line cards do not carry this setting with them when they are moved to
different slots or different chassis.
AT-CM Line
Cards and
Remote Peer
Management
The discussions so far have concerned the configuration files found on the
local AT-CM Line Cards. These are the line cards that reside in the same
chassis as the management card. But most of this information also
happens to apply to remote AT-CM Line Cards. These are line cards that
are managed through the remote peer management feature. This feature,
which is explained in “Remote Peer Management” on page 56, lets you
manage remote line cards through their local AT-CM Line Card
counterparts.
When the management card polls a local line card for its parameter
settings, it checks to see if the local line card has a remote peer
connection to a remote line card. If there is a remote peer connection, the
management card also polls the remote line card for its configuration, as
well, and stores the configuration in its master configuration file. This
makes it possible for you to restore the configurations to the remote line
cards just as you can to the local line cards. For instance, if you install a
new line card in a remote chassis, you can download the last saved
configuration to the line card from the management card to give the new
card the same configuration as the previous card in the remote chassis.
