Abstract:
A switching system comprises a controlling switch and multiple port extenders. The controlling switch includes: a plurality of controlling switch ports; and a first packet processor having a first forwarding engine. The first forwarding engine is configured to forward packets received at any controlling switch port to any other controlling switch port. Each of at least some multiple port extenders includes: at least one local upstream port coupled to the controlling switch directly or via another port extender; a plurality of local downstream ports; and a second packet processor having a second forwarding engine and a forwarding database. The second forwarding engine is configured to forward packets i) received at the downstream ports, and ii) for which the forwarding database does not include forwarding information, only to the at least one upstream port. The second packet processor has reduced functionality as compared to the first packet processor.

Claim (Index 10):
A method implemented in a switching system that includes a controlling switch and a plurality of port extenders that are coupled to the controlling switch, the method comprising:\n receiving packets via a plurality of local downstream ports of the plurality of port extenders; at each of at least some first packet processors disposed in at least some of the port extenders, performing a first set of packet processing functions, including:\n directing packets received from a port of the controlling switch to ports of the port extender according to forwarding decisions of the controlling switch, and \n rendering forwarding decisions for first packets received via the plurality of downstream ports to forward selected first packets to other downstream ports of the port extender if the destination addresses of the selected first packets are included in a forwarding database of the first packet processor of the port extender, and to forward selected second packets to a port of the controlling switch if the destination addresses of the selected second packets are not known to the port extender; \n at a second packet processor disposed in the controlling switch, performing a second set of packet processing functions, including:\n forwarding packets received at any controlling switch port to any other controlling switch port.
