Protected Ports (Private Vlan Edge) - Dell Networking 7048 Configuration Manual

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.
