Saving configuration for Brocade fiber optic switches

Brocade switch configurations can be backed up using FTP, SFTP, or SCP to an external server, with backups being non-disruptive and restores requiring a maintenance window.

Backup Overview

Backing up Brocade switch configurations is essential to prevent loss of zoning and fabric settings, especially before firmware upgrades or configuration changes. Backups are non-disruptive, meaning they do not affect switch operations, but restoring a configuration is disruptive and should be performed during a planned maintenance window .

Supported Protocols

You can use the following protocols to transfer configuration files to an external server:

• SCP (Secure Copy Protocol) – default and secure option
• SFTP (Secure File Transfer Protocol)
• FTP (File Transfer Protocol) – less secure, but supported Ensure the server host key is correctly configured on the switch before initiating the backup .

Backup Methods

Using Web Tools or CLI

1. Web Tools: Navigate to the configuration backup section, specify the server details, protocol, and file path, then initiate the backup. A confirmation message will indicate the estimated time for completion .
2. CLI: Use the configupload command to upload the configuration to a remote server. Example:

configupload -p ftp -h -l -u -s

Replace , , , and with your server details .

Automated Script

You can automate backups using a Perl or shell script on a UNIX/Linux host. Steps include:

• Create a low-privilege user on the host for backups
• Generate SSH keys for passwordless authentication
• Configure the script with server and switch details
• Schedule the script to run periodically, storing backups in a directory for archival

Restore Considerations

• Restoring a configuration overwrites the current switch settings and may require a reboot .
• Only use configuration files from the same switch model to avoid failures .
• Perform restores during planned downtime to minimize traffic disruption .

Best Practices

• Regular Backups: Schedule frequent backups to ensure the latest configuration is saved.
• Verify Integrity: Always confirm that the backup file is complete and accessible before performing firmware upgrades.
• Separate Storage: Store backups on a dedicated server or external storage to prevent accidental loss.
• Avoid Cross-Switch Copying: Do not copy configuration files between different switch models . By following these procedures, you can maintain reliable backups of Brocade switch configurations, ensuring quick recovery and consistent fabric management.
