Symptom

1800s running 1.3.3.0 could not be PnP through wireless. It could be PnP through wired however. The DNAC was in the same subnet as the WLC's service port. During the wireless PnP process, the sensor was claimed. It then went into the Onboarding process. In the middle of the process, the sensor lost the connectivity to DNAC. PnP was eventually timed out. The sensor was then put in in the Error state. DNAC registered "NCOB02074: Executing Workflow Timed Out, Please check the device connectivity with the Server." in the history. 1800s running 1.3.1.2 was successfully in wireless PnP.

Conditions

1800s running 1.3.3.0. DNAC is in the subnet as the WLC. DNAC: 1.3.3.3, 1.3.3.4 WLC: 9800 16.12.2t

Workaround

Downgrade the sensor to 1.3.1.2. Or use the wired connection.
