DFM 2.0.6 is reporting a duplicate IP address alert that has been cleared from the device long time ago. This alert appeared on the previous version of DFM, it was a legitimate alert then. The IP address was removed from both devices already and yet DFM is still reporting it as duplicate, eventhough it doesn't exist on any of the reported devices anymore. Upgrading to the latest DFM version also didn't help.
Some alerts have a tendency not to clear on their own. Since you now have DFM 2.0.6, you can manually clear these alerts. To do this, drill into the alert from the AAD screen, and click the Clear button.
Then drill into the alert, and look at the associated event(s). Check the config for the interfaces that apparently have a duplicate IP, and make sure the IP address is not configured on the interface. Note: it is not sufficient to just have the interface shutdown. The address must not be present.
Note: it may be necessary to poll the ipAddrTable to get the same information that DFM sees.
