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 15):
The method of  claim 10 , further comprising:\n populating the forwarding database with network address/port association information based on source MAC addresses of packets received via the plurality of local downstream ports; and not populating the forwarding database with network address/port association information based on source network addresses of any packets received via the at least one local upstream port.
