Recursive network discovery and vicinity dashboard

Hello all

I added 1 core switch to network discovery rule of type (recursive),

1- not all connected devices to the switch get discovered, (eventhough snmp is enabled and I can discover those devices if I add them explicitly to the discovery rule)

1- using recursive discovery I could see some of the connected devices are discovered but when I open network vicinity I don't see them connected to the core switch "cannot explin this, it has been discovered as connected device, but not shown in the vicinity dashboard.

the core switch has 2 sunbets and scom server is connected to these subnets as well ( using 2 network cards)

the scom server I used in the discobery isn't the RMS.

I don't get accurate result out of the network discovery and I don't know how to troublshoot this.. please assist.

Thanks
