Scheduled Subnet Scanning with Automatic Device Inventory Lifecycle Management

NetBrain currently requires manual initiation of subnet scans and does not support automatic, recurring discovery against a defined list of subnets. It also has no mechanism to automatically remove devices from inventory when they become unreachable for an extended period. This enhancement would allow administrators to configure a list of subnets for automatic, scheduled scanning, so that any new device responding with valid SNMP configuration is automatically added to inventory. It would also add a configurable time threshold after which a device on a monitored subnet that remains unreachable is automatically removed from inventory. Customers managing large or dynamic environments would benefit from reduced manual inventory upkeep and more accurate, self-maintaining device records.
