Additional Information

If somehow you encounter an issue during or after the controller upgrade, it's suggested to contact us with the following info:

• Omada Controller version (previous and current)
• Device Model(s), Hardware and Firmware versions
• (if possible) A copy of the Log file and Backup Config file

 

If you decide to downgrade the controller before reporting the issue to TP-Link, it's suggested to save a copy of the current Log file and Backup Config file before you do that, which could help to investigate and address the issue quickly.

 

>> How to get the Log file and Backup Config file for Omada SDN Controller:

• If your Windows software controller failed to get launched, please locate the controller installation path for the Log file.

• If it's not a launch issue, you can export the Log file and Backup Config file in the local network.

  • For Omada Controller v5.8 or later version,

    In the Global View, go to Settings > Maintenance > Backup & Restore > Retained Data Backup, select Settings Only, then click Export for the Backup Config file. On the same page, scroll down for Export for Support, click Export Running Logs for desensitized Log file.

  • For Omada Controller v5.6 or v5.7, 

    Go to Settings > Maintenance > Backup & Restore > Retained Data Backup, select Settings Only, then click Export  for the Backup Config file. On the same page, scroll down for Export for Support, click Export Running Logs for desensitized Log file.
