TFTP Configuration Backup

This section discusses the following:

• Optional TFTP Backup Parameters
• Default Backup Procedure
• Specific Configuration Backup Procedure
• Monitoring TFTP Configuration Backup

If you have a particular configuration of a Passport 4400 stored in configuration banks 3 or 4, a copy of that configuration can be uploaded to a TFTP host workstation for backup purposes. This configuration backup file can then be downloaded to a Passport 4400 unit at a later time for quick, first-time configuration or reconfiguration. To perform the backup, the requirements described in TFTP Software Download must be met.

For security purposes on the TFTP server, you may want to store backup configuration files in a separate directory from boot and application code images. The directory for backup configuration files must be both read and write accessible. An alternative security measure is to select a specific port or socket on the TFTP host machine through which to perform configuration backups.

Similar to TFTP file downloads, there are two methods that can be used to accomplish a TFTP configuration backup:

• Default Backup Procedure -- Set the source and target IP addresses and the backup file name, then execute the upload base configuration default procedure/command.
• Specific Backup Procedure -- Execute the upload base configuration specific procedure/command and set the parameters one by one "on the fly."

Each of these methods has its own advantages depending on your application environment.

Note: You can upload only one configuration image from a Passport 4400 at a time.
