Add Interface Status and User-Defined Fields to Duplicate IP/Subnet Manager View

The Duplicate IP and Subnet Manager view does not currently display interface administrative status, making it difficult to distinguish genuine duplicate address conflicts from interfaces that are administratively down and pose no immediate network risk. The view also lacks support for user-defined fields, so there is no way to tag or track individual duplicate entries over time, such as marking known and accepted duplicates versus items that require action. This enhancement would add an interface status column to the Duplicate IP and Subnet Manager view and introduce configurable user fields that allow entries to be tagged and followed through their lifecycle. Customers would benefit from clearer prioritization of true network risks, reduced false alarms from expected duplicate configurations, and improved ability to track remediation progress over time.
