Troubleshooting a Newly Discovered Device with Down Status
If the device status on the

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. Click 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, shown in
Figure 120
.
