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 4):
The switching system of  claim 2 , wherein the second forwarding engine is configured to:\n populate the second forwarding database with network address/port association information based on source network addresses of packets received via the plurality of local downstream ports; and not populate the forwarding database with network address/port association information based on source network addresses of any packets received via the at least one local upstream port.
