Troubleshooting a Newly Discovered Down Device

If the device status on the APs/Devices > List page remains Down after it has been added to a group, the most
likely source of the problem is an error in the SNMP community string being used to manage the device. Perform
the following steps to troubleshoot this scenario.
1. Select the Name of the down device in the list of devices on the APs/Devices > List or APs/Devices > Down
page. This automatically directs you to the APs/Device > Monitor page for that device.
2. Locate the Status field in the Device Info section. If the Status is Down, it includes a description of the cause
of the problem. Some of the common system messages are as follows in
Table 86 Common System Messages for Down Status
Message

Meaning
This means the AP no longer shows up in any controller's AP list (on the AirWave server). Either
the AP was removed from the controller, or it has roamed to another controller that AirWave does
not have visibility of, or it is offline.
When a controller goes down, AMP automatically marks all associated thin APs down (because
communication to thin APs are via the controller and AirWave assumes that if the Controller has
gone offline then all associated APs are down as well until reassociated another Controller).
The AP is in the process of downloading firmware or configuration (only applies to Cisco WLC thin
APs and some Symbol APs).
AMP could not fetch a config for the AP. Usually this is because the AMP has incorrect credentials
and was not able to log in.
The device is not responding and is likely offline.
