NotE. Some switches (as specified in the Private VLAN Catalyst Switch Support Matrix ) currently support only the PVLAN Edge feature. The term “protected ports” also refers to this feature. PVLAN Edge ports have a restriction that prevents communication with other protected ports on the same switch. Protected ports on separate switches, however, can communicate with each other. Do not confuse this feature with the normal PVLAN configurations that this document shows. For more information on protected ports, refer to the Configuring Port Security section of the document Configuring Port-Based Traffic Control.

Configuring Protected Ports
Some applications require that no traffic be forwarded between ports on the same switch so that one neighbor does not see the traffic generated by another neighbor. In such an environment, the use of protected ports ensures that there is no exchange of unicast, broadcast, or multicast traffic between these ports on the switch.
Protected ports have these features:
A protected port does not forward any traffic (unicast, multicast, or broadcast) to any other port that is also a protected port. Traffic cannot be forwarded between protected ports at Layer 2; all traffic passing between protected ports must be forwarded through a Layer 3 device. Forwarding behavior between a protected port and a nonprotected port proceeds as usual.
The default is to have no protected ports defined.
