I have Genian NAC deployed as a VM, trunked to all VLANs. I can ping the network sensor IP for each vlan from another host in the network. The software has picked up a few servers and most of the switches (all managed switches) but very few endpoint devices such as desktops, laptops, printers, etc. We have a layer 3 core switch with DHCP helper configured to forward DHCP requests to a Windows server running multiple DHCP scopes.
Not sure why there is limited visibilty in Genian. Do I need a SPAN port to a second vNIC in the VM?
