Protected Ports (Private VLAN Edge)
Private VLAN Edge (PVE) ports are a Layer 2 security feature that provides 
port-based security between ports that are members of the same VLAN. It is 
an extension of the common VLAN. Traffic from protected ports is sent only 
to the uplink ports and cannot be sent to other ports within the VLAN.
For information about configuring IPSG, see "Configuring Port-Based Traffic 
Control" on page 687.
