Abstract
This document describes tools that withhold a data packet from a switch port despite its destination address. In one embodiment, the tools may receive a port description identifying a set of switch ports. The tools configure the set of ports so that data packets exchanged through the switch by interested entities that would otherwise be forwarded to uninterested entities are instead withheld from the uninterested entities. In another embodiment, the tools may configure a data-packet switch according to a port description identifying a set of ports and a subset of the set of ports. The tools receive a data packet that includes a broadcast destination address on a receive port and then determine, based on the port description, whether the receive port belongs to the subset. If the receive port does not belong to the subset the data packet is withheld from the other ports of the set.
