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 14):
The method of  claim 11 , wherein:\n the second forwarding database is populated with entries indicating associations between i) respective media access control (MAC) addresses of devices coupled to local downstream ports of the port extender a) directly or b) via one or more other port extenders downstream from the port extender, and ii) respective local downstream ports of the port extender, wherein the second forwarding database excludes entries corresponding to MAC addresses of devices coupled directly, or via another port extender, to the at least one local upstream port of the port extender; and the method further comprising:\n at each of the at least some first packet processors and for a first packet i) received via one of the local downstream ports, and ii) having a destination MAC address in the forwarding database, forwarding the first packet to the different local downstream port indicated by the forwarding database, and \n at each of the at least some first packet processors and for a second packet i) received via one of the local downstream ports, and ii) having a destination MAC address not in the forwarding database, forwarding the second packet to the at least one local upstream port.
