Configuration file backup

The configuration file backup is an automatic, transparent process. After writing the configuration file
to FLASH, the switch writes to the primary configuration block, updates the CRC16 checksum to the
Multi Configuration area, and then saves the same information to the auxiliary configuration block.
After the switch boots, if it detects that the primary configuration file is corrupted (checksum
mismatch), it logs a message to the system log. The switch then attempts to load the secondary
configuration file, if the checksum is correct on the auxiliary configuration block, and logs a message
to the system log.
If both primary and auxiliary configurations blocks are corrupted, the settings are restored to default
and a message is created in the system log.
You can check the system log for messages indicating that a configuration block is corrupted. The
following are examples of messages the switch can forward to the system log for a corrupt
configuration file:
• Error loading primary configuration block <block number>
• Error loading backup configuration block <block number>
• Backup configuration block <block number> is in use
• Configuration files are corrupted. Restored to default
The following messages are loaded to the engineering log menu:
• Backup configuration restored from primary configuration block
• Backup configuration updated for next active configuration block

ASCII download log

The ASCII download log displays informational customer messages, describing the result of the
ASCII configuration file download, especially the failed commands. You can log four hundred
customer messages in dynamic random-access memory (DRAM).
The informational messages logged for describing the result of the ASCII configuration file download
are:
• Connection error (ACG_DOWNLOAD_ERROR): Indicates that the connection failed and the
ASCII configuration file cannot be accessed or used. The ACLI logged message contains the
