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?

Thank you for using Genian NAC.

We need to confirm a few questions to answer.
Please answer the following questions.

– Did you choose Trunk Port (802.1Q) during installation?
– In the System > Systems list in the menu, what are the values of ‘Up / All Nodes’ and ‘Up / All Sensors’?

Yes I chose 802.1Q during installation.

Up/All Nodes 7/7

Up/All Sensors 6/6

Ok, I solved it.  The sensors on each vlan were set to none except for the sensor matching the management vlan of the VM.  I went to system, sensor, and changed all the sensor modes to host.  Now there are 107 devices and climbing.
