Abstract
Theft detection in data center networks may be provided. First, a first leaf switch may create an entry in a first distributed secure cache in response to an endpoint appearing on the first leaf switch. The entry may correspond to the endpoint and may be marked as having a tentative state. Then a request message may be sent to a plurality of leaf switches. The request message may comprise data identifying the endpoint. Next, a reply message may be received in response to the request message from a second leaf switch within the plurality of leaf switches. The tentative state may then be removed from the entry in response to the reply message indicating that the endpoint is valid.
