5.2.5 VLAN Port Isolation Configuration
Function name: Port Isolation Configuration
Function description: Port Isolation provides a method to isolate ports on layer 2 switches on the same VLAN to restrict traffic
flow. It applies to a switch that has more than one port, and each port is configured as a protected port or a non-protected port.
An address table memory stores an address table with a destination address and port number pair. A forwarding map generator
generates a forwarding map that responds to a data packet’s destination address. 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 a data packet is matched with a physical address on the 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 all the ports indicated by the
forwarding map generated based upon whether the ingress port was configured as a protected or non-protected port.
