ACI Private vlan equivalent with Cat Switches

Hi Folks,

I am migrating my 2 x Catalyst switches connecting to N5K (VPC) in the existing environment  to ACI Fabric leaf's in VPC. The catalyst SW have Private VLANs.

 

Desired/expected result is to have private VLAN communication with between clients connected between the catalyst switches in ACI environment.

 

In ACI, I have 3 epg's for each of the VLANs (Pri, Isolated (intra isolation enabled), Community) under single BD, under a single vrf/tenant. The VPC port channel (dot1q trunk) formed good. 

 

During the testing, I experience intermittent ping drops due to MAC flaps seen between the client connected interface and the port-channel (dot1q trunk) towards leaf, with the normal VLAN I don't face this issue. 

 

If anyone experience this before, can help on this issue? thanks!

It looks like ACI is not compatible with private VLANs configured on legacy switches which are connected to leafs.

Did you find any solution for this issue?
