148 | VLAN Commands
www.dell.com | support.dell.com
This section describes commands you use to configure and view protected ports. Ports are unprotected
by default. A Private Edge VLAN, also referred to as a “protected VLAN” — PVLAN), prevents ports
designated as such in the specified protected port group from forwarding traffic to each other even if
they are on the same VLAN. However, protected ports can forward traffic to all unprotected ports in
their group. Unprotected ports can forward traffic to both protected and unprotected ports.
