A down device is one that is unreachable and not responding to ICMP ECHO or other monitoring protocols, such as ARP cache retrievals. The device may be booted and online, but something is preventing a response. If the device is responding to ARP only, it is indicated with an asterisk.

When a device is not responding to the Onsite Manager discovery scan or Device Manager is down, Service Center continues to keep full asset, description, and addressing information for the device until the specified interval triggers the next clean-up.
Even though a device may be down, you may not want to delete the device.
What You Can Do
To ensure that the information you see in the dashboards and reports is fresh and accurate, you can
- Delete down devices manually.
- Delete down devices automatically on a schedule after a specified period of inactivity.
