What is unmanaging a device?
Unmanaging devices
Using the NSP to unmanage a device excludes the device from the managed network.
The unmanage function may be used for unusual conditions such as when the NSP requires a complete refresh of device data because of data corruption, or when NEs are decommissioned.
The next time the discovery rule scans the network, it discovers and manages the device again.
Note: If you need to unmanage and re-manage an NE with a telemetry subscription configured, a delay may be required to ensure the telemetry subscription will be automatically reinstated. To ensure the telemetry subscription is created again, Nokia recommends waiting at least 15 minutes between unmanaging and re-managing the NE.
