Description
This article describes the recommended steps to be performed when a network Inventory device is replaced and assigned the same management IP as the old entry.
Scope
FortiNAC.
Solution
When adding a switch or router that will use the same IP address as the original device modeled in Topology, the original model must be deleted from the database, and a new model must be added. This ensures all internal mappings and related files associated with that model are correct for the new device. Otherwise, unexpected behavior occurs.
Examples include:
- Unable to read VLANs.
- L2/L3 Poll failures.
- Credential validation failure.
- Switching VLANs on the wrong ports.
Deleting the model from FortiNAC removes all manual switch devices and port groupings done on the switch model.
- Review the model of the device to be replaced. Note or take screen captures of all configurations, including port and device group memberships. They will need to be re-entered later.
- Ensure the new device is configured appropriately.
- Once the original device is decommissioned, delete the old device model.
- Once the new device is on the network, add it to Topology using the appropriate credentials.
- Configure the device model using the settings recorded in the previous step.
