4.0(3d) 4.1(1j)

Description (partial)

Symptom:
Host subnets (/32) that are created under an SCVMM-integrated EPG get pushed as a virtual machine subnet under the virtual machine network in SCVMM. Virtual machine networks on SCVMM  do not support /32 virtual machine subnets and fail to come up. Virtual machines that were previously associated to the virtual machine networks lose connectivity.

Conditions:
EPG has to be integrated with SCVMM ( should have SCVMM VMM domain under domains in the EPG) . /32 host subnets are created under the EPG.
