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 1):
A switching system, comprising:\n a controlling switch including:\n a plurality of controlling switch ports, and \n a first packet processor coupled to the controlling switch ports, the first packet processor including a first forwarding engine that includes, or is coupled to, a first forwarding database, wherein the first forwarding engine is configured to forward packets received at any controlling switch port to any other controlling switch port; and \n a plurality of port extenders, each of at least some of the port extenders including:\n at least one local upstream port coupled to the controlling switch directly or via another port extender, \n a plurality of local downstream ports, and \n a second packet processor coupled to the at least one local upstream port and the plurality of local downstream ports, the second packet processor including a second forwarding engine that includes, or is coupled to, a second forwarding database, wherein: \n the second forwarding engine is configured to forward packets i) received at the downstream ports, and ii) for which the second forwarding database does not include forwarding information, only to the at least one upstream port; \n wherein the second packet processors have reduced functionality as compared to the first packet processor.
