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.
