Abstract
A switch is configured to block packets from being transmitted through designated ports. The switch has port bitmap generator configured to obtain a port bitmap and a table is configured to store a block mask indicating which port the packet should not be transmitted. A block mask lookup is configured to determine the block mask for the packet from the table, and a transmit port bitmap generator is configured to determine which ports the packet should be transmitted using the port bitmap and the block mask.
