Abstract: Systems and methods are provided for overlaying a virtual network on a physical network in a data center environment. An overlay system is arranged in an overlay virtual network to include an overlay agent and an overlay helper. The overlay agent is implemented in an access switch. The overlay helper is implemented in an end station that is in communication with the access switch. Overlay parameters in compliance with an in-band protocol are transmitted between the overlay agent and the overlay helper.

Abstract: In one embodiment, a system includes at least one processor and logic integrated with and/or executable by the at least one processor, the logic being configured to receive, by the at least one processor, a request to assign a media access control (MAC) address to a device on a port, determine, by the at least one processor, the MAC address to assign to the device based at least partially on the port, and send, by the at least one processor, a response to the request with the MAC address. According to a further embodiment, the logic may be configured to create a MAC address allocation table that includes a plurality of hash values, each hash value being associated with one port and a plurality of MAC addresses, wherein the assigned MAC address is one of the MAC addresses associated with the port in the MAC address allocation table.
