# Traffic Insights General Settings

Use the **General Settings** screen to configure behavior that applies across all Traffic Insights screens.

## Configuring Interface Data Source

By default, Traffic Insights uses NetFlow v9 (with the interface options template) or IPFIX as the interface data source for Cisco networks and other supported devices. You should only change this setting if you need interface information from non-Cisco devices or if interface metadata is not being sent via NetFlow v9/IPFIX.

### Changing Interface Data Source

1. Navigate to **Traffic Insights > Settings > General Settings**.
2. In the **Interface Name Source** section, select the radio button of the source you want.
3. Review the warning message explaining impacts on existing configurations.
4. Click **Save** to apply the change.

{% hint style="warning" %}
Changing the interface data source may alter interface names displayed throughout the platform, potentially affecting existing alerts, dashboards, and filters. Review the impact carefully before making this change.
{% endhint %}

### When You Change Data Sources

* **Interface Names:** May change to reflect the new naming conventions.
* **Hierarchy Display:** Shows device-interface relationships based on the new data source.
* **Existing Alerts:** Typically continue to function, but we recommend you verify alert configurations after the change.
* **Dashboards:** Interface names update to reflect the new data source.
* **Path Visualization:** Remains unchanged (always uses SNMP).
* **Data retention:** The platform continues to show device and interface names from the previous data source for a retention period of 30 days. These names time out after the retention period, when you will no longer see them in filters or views.

## Configuring Flow Consolidation

Flow consolidation combines records for the same conversation when multiple traffic monitors report that conversation. It affects how Traffic Insights calculates and displays aggregated traffic, but it does not reduce the number of records counted toward your FPS limit.

To enable or disable flow consolidation:

1. Go to **Traffic Insights > Settings > General Settings**.
2. Locate **Flow Consolidation**.
3. Enable or disable the setting.
4. Select **Save**.

Changing this setting can affect displayed throughput and existing alert thresholds. For details, see [Flow Consolidation](https://docs.thousandeyes.com/product-documentation/traffic-insights/traffic-insights-views-and-settings/flow-consolidation).
