It was my understanding that most "fakes" come out of the same factories as the originals. So Cisco orders 1000 switches, but the factory has a secret midnight shift that assembles another 500 that go out the back door. It would take pretty tight supply chain controls to make sure that this isn't happening. As a consumer you wouldn't really care since you're getting the same product.
