Abstract
A network switch comprises a multiplicity of ports for receiving and forwarding addressed data packets, a forwarding engine for directing packets received at the ports to at least one other port, a register for storing unit identifications of a set of units including the network unit, and hashing logic for selecting one of the unit identifications in response to address data in a packet. The forwarding engine makes a determination whether the one of the unit identifications corresponds to the network unit and is operative to direct the packet in accordance with that determination. The use of the register enables a substantial increase in the number of ports that can be members of a stack-wide trunk.
