3-2-5. VLAN Port Isolation Configuration

Function name

Port Isolation Configuration

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 des-

tination 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 destina-

tion address of 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 des-

tination address of 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.
