2-­‐16.2 Port Isolation
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 is a switch with more than one port, with each port
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 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 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 the ports in accordance with
the forwarding map generated based upon whether the ingress port was configured as a protected
or non-­‐protected port.
This page is used for enabling or disabling port isolation on ports in a Private VLAN. A port member of
a VLAN can be isolated to other isolated ports on the same VLAN and Private VLAN.
