Troubleshooting a Newly Discovered Device with Down Status
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 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 87:
3. If the SNMP Get Failed message appears, select the APs/Devices > Manage tab to go to the management
page for that device.
4. If visible, select the View device credentials link in the Device Communications section. This displays the
credentials AWMS is using unsuccessfully to communicate with the device. This link can be removed from
AWMS for security reasons by setting a flag in AWMS. Only users with root access to the AMP command line
can show or hide this link. To disable this feature, please contact Dell support. Figure 103 illustrates this page.
Table 87 Common System Messages for Down Status
Message Meaning
SNMP Get Failed An incorrect SNMP community string or incorrect SNMP port is specified. If SNMP is not enabled
on the device, you will also receive this message. Some APs, including Cisco and Dell
PowerConnect W devices, do not have SNMP enabled by default.
Telnet Error: command
timed out
Telnet username and password specified for that device is incorrect, or an incorrect telnet port is
specified.
ICMP Ping Failed (after
SNMP Get Failed)
The device is not responding on the network and is likely non-operational.
