Perform Resync

The Resync function initiates one or more queries to the network and the controller to capture up-to-date information for this asset. You can run all available queries or specific queries.

The following are the queries available for Resync:

  • Backplane scan — Discovers modules and their specifications within a backplane.

  • DNS scanning — Searches for the DNS names of the assets in the network.

  • Details query — Retrieves the controller’s hardware and firmware details. The result appears in the Firmware field in the Assets > Controllers and Modules page.

  • Identification query — Uses multiple protocols to identify the asset.

  • NetBIOS query— Sends a NetBIOS unicast packet that is used to classify and detect Windows machines in the network.

  • SNMP query (for SNMP enabled assets) — Retrieves configuration details for SNMP-enabled assets.

  • State — Detects the current status of the asset (Running, Stopped, Fault, Unknown, and Test).

  • ARP — Retrieves the MAC address of new IPs detected in the network. The result appears in the Details > Overview section.

The Resync button may be disabled under specific conditions. Possible reasons include:

  • The device is unreachable or lacks available queries.

  • Permission configured on the Active Queries page may restrict non-administrator accounts from initiating certain queries.

  • Queries are not enabled on this OT Security deployment.

  • All queries in the Active Queries > Manual section are disabled.

  • The asset lacks a known IP address for querying.

To run Resync asset data:

  1. On the Asset Details page for the required asset, in the upper-right corner, click Resync.

    A drop-down list of queries appears.

  2. Click the query that you want to run or click on Run All Queries to run all available queries.

    As each query runs, a notification appears with the status of the query.

For each completed query, OT Security updates the system data for that asset based on the new data.
