Network switch shows Non-active

[tgibney-Uni-Cas]

I have several running network switches that list in Assets automatically but appear "grayed out" and show Non-active.  I set them to Active but they reverted to Non-active after some time.  Each are pingable from the other.  Switches are on a management VLAN that is different from Lansweeper server's VLAN.  Could that be the reason?

Assets are marked as non-active depending on the configured Asset Cleanup Options (Configuration > Server Options) Perform automated database cleanups - Lansweeper Community

You can try modifying the value for the days it takes to mark assets as non-active and see if it makes any difference.  When was the last time they were scanned successfully?

The switches had been configured to only respond to a list of allowed IP addresses.  The switches were on the network long enough to register with SNMP then essentially become dark "Non-active" when that switch setting was made.  Very soon after adding the Lansweeper server in the "ip authorized-managers..." list the switches became Active.

What I meant by "Each are pingable from the other" is the switches can ping the Lansweeper server and the Lansweeper server can ping the switches.  Just to be clear...
