APIC not discovering some hosts

Hi

I did read one of the previous posts where EM do not discover wired endpoints.  I did look at the articles and suggestions posted and verified the environment my controller is installed in.

I have a slightly different issue here.  This is a multi vrf environment which is the first bit of complexity (need to sort out some routing here).  Then on the vrf that the controller is installed in, it would only discover some of the connected devices.  The client runs ipt with most of the phones being detected but not all the PCs. 

The access layer is mostly c3750 stacks.  These connect to a pair of N7K core switches.  these, in turn, connects to a pair of N5K switches that the servers connect to. 

Besides the limited discovery in the access layer, I do not see a single device that connects to the N5Ks (data center)

Could anyone give me some advice here?

PS. I am running APIC-EM Version 1.4.3.1009.

Thanks in advance

It sounds like you need IPDT enabled on all of the devices.
