USG FLEX H Series - Bootup Status

Introduction

Understanding the bootup status and configuration application process of the USG FLEX H Series firewalls is crucial for effective troubleshooting and maintenance. This guide provides a detailed overview of the bootup sequence, symbols used during the process, and how to interpret various status indicators.

Bootup Sequence

When the USG FLEX H Series firewall powers on, it follows a specific sequence to apply its configuration files. This sequence helps identify and troubleshoot any issues that may arise during the bootup process.

Bootup Symbols on Console Cable

The firewall uses a series of symbols to indicate the progress and status of the configuration application, these symbol can be displayed when connecting via console cable:

  • Start Applying Startup Config (•): Indicates that the firewall is applying the startup configuration.
  • Start Applying Last Good Config (@): Indicates that the firewall is applying the last good configuration.
  • Start Applying System Default Config (*): Indicates that the firewall is applying the system default configuration.
  • Success ($): Indicates successful application of the configuration.
  • Failure (X): Indicates a failure to apply the current configuration.

Bootup Status on the Dashboard

The main dashboard of the firewall provides a visual representation of the current configuration status. This section explains how to interpret the status indicators.

Status Indicators

  • OK Sign: Indicates that the boot process and configuration application were successful.
  • Warning Sign: Indicates there was an issue during the boot process.

Detailed Status Descriptions

Hovering over the status indicator on the dashboard provides detailed descriptions of the current status:

  • Boot Success: Configuration applied successfully.
  • Firmware Update Success: Configuration applied successfully after a firmware update.
  • User Rebooted: Device was rebooted by the user.

Warning Messages

In case of issues, the following warning messages may appear:

  • Fallback to Last Good Configuration: Indicates the firewall reverted to the last good configuration due to issues with the startup configuration.
  • Fallback to Last Good Configuration After Firmware Update: Indicates the firewall reverted to the last good configuration following a firmware update.
  • Error Fallback to System Default Configuration: Indicates the firewall reverted to the system default configuration due to issues with both the startup and last good configs.
  • Error Fallback to System Default Configuration After Firmware Update: Indicates the firewall reverted to the system default configuration following a firmware update due to configuration issues.

Troubleshooting

Console Output

If you experience issues during the bootup process, connecting a console cable to the firewall provides real-time feedback on the boot sequence and configuration application. This can help identify where the process fails and what configurations are causing the issue.

Event Logs

Review the event logs for detailed error messages. The logs will provide information on stage one and stage two errors, helping you pinpoint the exact lines and configurations causing issues.

Using the Test Option

To validate new configurations before applying them, use the test option available in the web GUI or CLI. This helps ensure that configurations are error-free and ready for deployment.

Configuration File Header

Ensure that the configuration file header matches the model name and firmware version of your firewall. This helps avoid issues when applying configurations from one device to another or when downgrading firmware versions.

Conclusion

Understanding the bootup status and configuration application process is essential for maintaining the USG FLEX H Series firewalls. By following the steps outlined in this guide, you can effectively troubleshoot and resolve configuration issues, ensuring your firewall operates smoothly and efficiently.
