3.15.2 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 comprises a switch with 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 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 identified by 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.
WEB INTERFACE
To configure Port Isolation configuration in the web interface:
1. Click Private VLAN, Port Isolation.
2. Select the port for which you want to enable Port Isolation.
3. Click Apply.
