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 11):
The method of  claim 10 , wherein:\n the forwarding database is populated by entries that further indicate associations between i) respective network addresses corresponding to devices coupled to downstream ports of the port extender via one or more other port extenders downstream from the port extender, and ii) respective ports of one or more other port extenders, downstream from the port extender, to which the devices are coupled; and the method further comprises, when an entry in the forwarding database indicates that a destination network address of the first packet is associated with a downstream port of another port extender, including in a tag corresponding to the first packet an indication of i) the other port extender, and ii) the downstream port of the other port extender.
