DHCP Relay for Clearpass profiling

I'm trying to get wired profiling set up between our clearpass server and wired clients. I already have profiling working for my wireless clients.

 

I have two DHCP relays setup on a test VLAN, one for the DHCP server subnet, and one for the clearpass subnet. I'm receiving DHCP addresses, but not seeing these devices get profield by clearpass. 

 

 

Does clearpass need the DHCP relay to point directly to clearpass, or can it point to the subnet it is in?

The DHCP relay needs to forward client DHCP relay requests directly to the ip address of the ClearPass Box.

Thanks Joseph, that worked out.

 

Why does the DHCP helper need to point at clearpass instead of the subnet, shouldn't clearpass see the DHCP broadcast when it's relayed to the subnet clearpass resides in?

ClearPass needs to receive a unicast, not multi/broadcast packet for the fingerprinting process.
