Configuration Backup
ThirdEye allows you to use the functionality of the Net LineDancer config management tool.
In ThirdEye, obtaining the device configuration is called a “Configuration Backup”. For configuration backup, ThirdEye connects to the device via SSH or Telnet and retrieves the configuration using show commands, TFTP commands, etc.
Before performing a configuration backup, ensure the following requirements are met:
-
A login username and password for logging into the device have been set. Refer to the Credentials section to make sure the credentials are set.
-
The model supports configuration backup by ThirdEye. For a list of supported devices, visit https://logicvein.com/supported-devices.
-
The NCM (Network Configuration Management) function is enabled. The target of configuration backup is the device with
ncmdisplayed in the trait column.

NCM (Network Configuration Management)
The Network Configuration Management (NCM) in ThirdEye functions as a monitoring-centric tool that automatically tracks device configuration states as part of its network surveillance system. Implemented as an optional module, it focuses on preserving configuration integrity for already-deployed devices within monitored networks.
In ThirdEye, the NCM performs the following functions:
- Provides historical versioning of configurations
- Detects unauthorized changes through SNMP-triggered alerts
- Supports compliance checks against predefined baselines
To enable NCM functionality, click the target device in the [Inventory] main tab, and click [Enable NCM functionality] in the menu bar’s [Device] menu.
Backup Status
After the backup, the status icon displayed on the left side of the device view will change. The icons used for backup status are as follows.
| Icon | Status | Condition Description |
|---|---|---|
| Backup complete | Configuration acquisition has completed successfully. | |
![]() |
Configuration mismatch | There are differences between the device’s running-config and startup-config. Doubleclick the icon to see the comparison results. |
| Credential mismatch | You cannot log in with the registered credentials and the backup is failing. Please check your credential settings. | |
| Backup failure | Backup has failed for some reason. | |
| Backup not executed | No backups have been performed. | |
![]() |
Warning | This device violates a compliance policy with severity set to Warning. |
![]() |
Error | This device violates a compliance policy with failure level set to Error. |
The icon displayed in the status column is the icon with the highest priority among the severity and backup status set in the trigger in the monitor settings.
| Priority | Status | Severity Status Icon | Backup Status Icon | Compliance Status Icon |
|---|---|---|---|---|
| High | Emergency | - | - | |
| Alert | - | - | ||
| Backup failure | - | - | ||
| Critical | - | - | ||
| Credential mismatch | - | - | ||
| Config mismatch | - | ![]() |

| Priority | Compliance error | - | - | ![]() |
| Error | - | - | ||
| Compliance warning | - | - | ![]() |

Acquired Configuration
You can check the acquired configuration from the device details screen.

You can check the contents by double-clicking on the [Config] button.

Compare Configurations
You can compare the configurations by selecting two configurations and clicking the [Compare] button.
Multiple selections can be made by holding down the [Ctrl] key while selecting.

When you compare configurations, configuration differences are highlighted in color. Each type of difference is displayed in a different color, with red representing deleted parts, yellow representing changed parts, and green representing added parts.

Disable Configuration Backup
Even if the model supports configuration backup, if you do not want to acquire the configuration, you can exclude it from the backup target by disabling the NCM function.
To disable NCM functionality.
- Click the target device in the [Inventory] main tab.
- Click [Disable NCM functionality] in the Menu Bar’s [Device] menu.

Disabling the NCM feature will remove the “ncm” trait from the device’s properties, and “ncm” will no longer appear in the device’s traits.

Enable Configuration Backup
To enable the NCM function:
-
Select the target device.
-
Click [Enable NCM function] in the [Device] submenu.
Enabling the NCM feature will add the “ncm” trait to the device’s properties, and “ncm” will appear in the device’s traits.
