3-11.5.2 Port
Isolation
Parameter
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 a 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.
