Abstract
A network switch includes a plurality of isolated ports, each associated with a private domain. The switch also includes a network port associated with the private domain. A memory in the switch maintains a hardware-based forwarding table for the private domain. Processing logic in the network switch prevents forwarding of packets between isolated ports within the private domain based at least in part on a privacy level associated with each entry in the hardware-based forwarding table for the private domain.
