Hi ,
Anyone can help guide me. How to solve this issue.
My authorization rules allow ONLY Registered Device to access. During the testing I deleted a client's MAC from Endpoint Identity Group List > RegisteredDevices. Then I try to register the device again through My Devices portal. Error show "Device ID already exists".
I try to find out from the document but it's not much help. The document is not clear. It said
Errors When Adding Devices to My Devices Portal
Employees cannot add a device, if another employee has previously added it such that the device already exists in the Cisco ISE endpoints database.
If employees attempt to add a device that already exists in the Cisco ISE database:
• And it supports native supplicant provisioning, we recommend adding the device through the BYOD portal. This will overwrite any registration details that were created when it was initially added to the network.
• If the device is a MAC Authentication Bypass (MAB) device, such as a printer, then you must resolve ownership of the device first. If appropriate, you can remove the device from the endpoints database using the Admin portal, so that the new owner can successfully add the device using the My Devices portal.

When I try to add a device, I get an error that says that the device already exists, but I do not see it listed as one of my devices. How can I add this device?
That error means that someone has already added the device to the system. If it does not appear on your list, one of your coworkers has registered the device already.
You have several options for resolving this situation:
• If you are attempting to add a device such as a printer, you will need to contact your help desk to locate the current owner and to resolve this issue for you.
• Regardless of the device type, you can contact your help desk so that they can verify who registered the device previously and delete it from the database so you can re-register it.
Some source tell me to delete device from My Device portal that was registered. However, the device is not shown there.
Any suggestions are welcome. Thank you.
