Abstract: A method is described and in one embodiment includes receiving at a top-of-rack (“TOR”) switch a notification concerning a virtual machine (“VM”), wherein the received notification identifies a host associated with the VM; determining whether the identified host is directly connected to the TOR switch; and if the identified host is not directly connected to the TOR switch, identifying an intermediate switch to which the identified host is directly connected; and determining whether the identified intermediate switch to which the identified host is directly attached is attached to the TOR switch.

Abstract: In an example, there is disclosed a network switch, including: an ingress interface; an egress interface; an endpoint repository network interface; and one or more logic elements including an endpoint admission control engine to: receive a packet on the ingress interface, the packet having an associated source Internet protocol (IP) address and virtual network identifier (VNI); query an endpoint repository via the endpoint repository network interface for the source IP address and VNI; determine that the source IP address and VNI are found in an endpoint repository database of the endpoint repository; and forward the packet to a destination IP address via the egress interface.
