4.4.5 VLAN 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 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.
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.
