3-3-5. Port Isolation
Function name:
Port Isolation
Function description:
Port Isolation provides for an apparatus and method to isolate ports on layer 2 switches
on the same VLAN to restrict traffic flow. The apparatus comprises a switch having said
plurality of ports, each port configured as a protected port or a non-protected port. An
address table memory stores an address table having a destination address and port
number pair. A forwarding map generator generates a forwarding map which is
responsive to a destination address of a data packet. The method for isolating ports on
a layer 2 switch comprises configuring each of the ports on the layer 2 switch as a
protected port or a non-protected port. A destination address on an data packet is
matched with a physical address on said layer 2 switch and a forwarding map is
generated for the data packet based upon the destination address on the data packet.
The data packet is then sent to the plurality of ports pursuant to the forwarding map
generated based upon whether the ingress port was configured as a protected or non-
protected port.
