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 11):
The method of  claim 10 , further comprising:\n at each of the at least some first packet processors, searching a first forwarding database of the at least some of the port extenders populated with entries indicating associations between i) respective network addresses of devices coupled to local downstream ports of the port extender directly or via one or more other port extenders downstream from the port extender, and ii) respective local downstream ports of the port extender, wherein the first forwarding database excludes entries corresponding to network addresses of devices coupled directly, or via another port extender upstream from the port extender, to at least one local upstream port of the port extender that is coupled to at least one port of the controlling switch; and at the second packet processor, searching a second forwarding database populated with entries indicating associations between i) respective network addresses of devices coupled to local downstream ports of the plurality of port extenders directly or via one or more other port extenders, and ii) respective controlling switch ports.
