Abstract:
A switching system comprises a controlling switch and a plurality of port extenders. One of the port extenders includes: at least one upstream port; multiple downstream ports; and a forwarding engine. A forwarding database is populated with entries indicating associations between i) respective network addresses corresponding to devices coupled to downstream ports, and ii) respective local downstream ports. The forwarding database excludes entries corresponding to network addresses corresponding to devices coupled to the at least one upstream port. The forwarding engine is configured to: for a first packet received via one of the local downstream ports, and having a destination network address in the forwarding database, forward the first packet to a different local downstream port indicated by the forwarding database. For a second packet received via one of the local downstream ports, and having a destination network address not in the forwarding database, forward the second packet to the at least one upstream port.

Claim (Index 17):
The method of  claim 10 , wherein:\n the 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 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 comprises:\n for the 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 for the 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.
