Global Setting to Designate Primary Data Source Between CLI and API

NetBrain currently does not provide a way for administrators to designate which data collection method, CLI or API, should serve as the authoritative source when both are configured for a device. When the two sources report conflicting values for items such as configuration content, serial number, or interface status, the platform has no defined precedence rule, which can lead to inconsistent or inaccurate data being displayed or used in downstream tasks. This enhancement would add a global setting that lets administrators specify a primary data source, either CLI or API, with the secondary source used automatically only when the primary source is unavailable or fails to return data. Customers operating hybrid environments with both CLI and API-managed devices would gain more predictable data accuracy and reduced troubleshooting effort tied to source conflicts.
