Abstract
Network switch modules are cascaded in a prescribed sequence to support higher port requirements. The network switch modules may circulate a received frame indefinitely if the frame is not destined for any one of the output ports of the cascaded arrangement of network switch modules. Frame forwarding logic within each of the cascaded network switch modules is employed to determine when a network switch module should cease forwarding the received frame. Specifically, the frame forwarding logic takes the frame out of circulation based upon the sequence identifier of the network switch module and an embedded identifier associated with the frame.
