    Abstract: In one embodiment, a method includes receiving network traffic, determining whether packets have an overlay header, terminating a tunnel and de-encapsulating inner packets of packets having an overlay header, performing services on the inner packets in response to a determination that services are to be performed on the inner packets, originating a tunnel, encapsulating a first packet of the serviced inner packets with an overlay header, and switching the encapsulated serviced inner packets to a destination address in a virtual network in response to determining that the first packet is to be switched to the destination address in the virtual network, and switching a second packet of the serviced inner packets to a destination address in a non-virtual network without encapsulating the serviced inner packets with the overlay header in response to a determination that the second packet is to be switched to the destination address in the non-virtual network.

    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.
