Abstract
Packet switch operating methods and packet switches receive a packet on a first port of the packet switch. The packet is addressed to a device that is in communication with a second port of forwarding circuitry of the packet switch and the packet has an Ethernet destination address field and an Ethernet source address field. The Ethernet destination address field includes a first address and the Ethernet source address field includes a second address. The methods and packet switches also forward the packet to an output queue associated with a third port of the forwarding circuitry, forward the packet from the output queue to the first port, and modify the packet so that the Ethernet destination address field comprises the second address instead of the first address.
