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 1):
A port extender for use in a switching system comprising a controlling switch and one or more other port extenders, the port extender comprising:\n 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 forwarding engine coupled to the at least one local upstream port and the plurality of local downstream ports, the forwarding engine including, or being coupled to, a forwarding database that is populated with entries indicating associations between i) respective network addresses corresponding to 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 network addresses corresponding to devices coupled directly, or via another port extender upstream from the port extender, to the at least one local upstream port of the port extender, wherein the forwarding engine is configured to:\n for a first packet i) received via one of the local downstream ports, and ii) having a destination network address in the forwarding database, forward the first packet to a different local downstream port indicated by the forwarding database, and \n for a second packet i) received via one of the local downstream ports, and ii) having a destination network address not in the forwarding database, forward the second packet to the at least one local upstream port.
