Description (partial)

Symptom:
When the productSpec of a DVS is changed from Cisco Systems to Vmware Inc as a workaround for bug CSCvr86180, if the VMware vCenter is reloaded after that point, that will result in a change of the object type at the VMware vCenter (DistributedVirtualSwitch to VmwareDistributedVirtualSwitch). That has the effect of the Cisco APIC deleting the hvsLNode the next time it pulls inventory from the VMware vCenter after the VMware vCenter comes back up.

When the productSpec is switched back to Cisco Systems, a new hvsLNode is created with most of the fields left as uninitialized, which raises faults on the DVS. Lnode(DVS) gets deleted on the external VMM controller and the MTU on the DVS is different than the MTU in the policy.
This is a cosmetic issue. There is no functionality impact.

Conditions:
This issue occurs when the productSpec of a DVS is changed from Cisco Systems to Vmware Inc.
