Hi all, NMS does not show links between devices after being configured, after some time the links disappear, any idea of what may be happening? The version of NMS is 8.1.2.59.

Hello,

We've seen this behavior is a device has been modeled multiple times using different management IP addresses, or if one of the discovery protocols provides incorrect information and overwrites what we've learned with another protocol.

How to debug the links:

How to limit discovery protocols if you find that one is providing incorrect data:

Maps issues are difficult to diagnose, I would suggest creating a ticket with GTAC.

Thanks
